Abstract

The air conditioner includes a housing having an air intake port and an air outlet port respectively arranged on a surface intersecting a horizontal plane and on a surface on the opposite side, and a heat exchanger and a cross-flow fan arranged in a row in the housing. The cross flow fan is driven such that the upper half side thereof rotates in a direction from the heat exchanger toward the blowout port. Bending of the flow path of the air in the case, that is, the in-body flow path is indispensable for the air blowing operation based on the rotation of the cross flow fan. In order to achieve the buckling of the flow path in the body, the air conditioner is provided with an air flow adjustment portion, so that an air flow from the obliquely downward direction to the cross flow fan is generated on the air intake side, and an air flow from the cross flow fan to the obliquely downward direction is generated on the blowout port side.

Description

Air conditioner and radiation air conditioner using the same

Technical Field

The present invention relates to an air conditioner and a radiation air conditioning device using the same.

Background

As an air conditioning apparatus for maintaining the comfort of the environment of an indoor space, a convection system has been generally used. The air conditioning system is a system in which air-conditioned air whose temperature and humidity have been adjusted is blown into a room, and air conditioning is performed by convection.

However, the convection method is liable to be uncomfortable in terms of comfort.

One of the reasons for this is that when air is convected, a difference in vertical temperature distribution occurs in the indoor space, and warm air tends to go to the ceiling side and cool air tends to stay on the floor. The health-care pillow is always uncomfortable because the pillow is in a state opposite to the head cold and foot heat which are beneficial to health and are comfortable for people.

Another cause of the easy dissatisfaction is that the convective air flow directly touches the human body, creating a phenomenon called cold feel (draft). For example, it is said that the temperature of the body temperature drops by 3 ℃ at a wind speed of 0.5m in a room where refrigeration is effective. Therefore, when entering an air-conditioned room from outdoors under the sun, the user feels comfortable at first, but feels cold after the body is cooled.

In addition, there are many people who feel uncomfortable because the airflow continues to collide with the body itself.

The radiation type air conditioning apparatus improves the above-described drawbacks of the convection type air conditioning apparatus in that the air flow is not directly collided with the body.

As an example of such a radiation type air conditioner, patent document 1 discloses an air conditioner in which an air conditioner and a radiation panel are mounted on a ceiling surface (patent document 1 is referred to as a "radiation air conditioning system").

The radiation panel is configured such that an air passage is formed between the radiation panel and the heat-insulating panel which face each other and have moisture permeability, and an inlet of the air passage faces a blowout port of the air conditioner (see paragraphs [0025] to [0029] of patent document 1, fig. 1 to 11). Accordingly, the air-conditioning air blown out from the outlet of the air conditioner is introduced into the air duct and circulated in the air duct. Thus, the temperature of the radiation panel can be controlled to perform radiation cooling and heating.

Disclosure of Invention

Technical problem to be solved by the invention

Patent document 1 discloses a thin air conditioner having a height low in the vertical direction (see fig. 5 to 11 of document 1). With regard to this air conditioner, patent document 1 describes "cooling or heating is performed by an endothermic or exothermic action that is accompanied by a phase change of a heating agent fluid by introducing air of the indoor space 1 so that the cooled or heated air is ejected from the air-conditioning air ejection port 211 a" (refer to paragraph [0027] of document 1). On the other hand, the internal structure of the air conditioner is not described, and details thereof are not known.

As a blowing source of the air conditioner, a cross flow fan is widely used. The cross flow fan can uniformly blow out the air-conditioning air even from a wide air outlet, and has a small operating sound, and therefore is suitable for use as an air supply source of an air conditioner.

Therefore, in the air conditioner described in patent document 1, the use of a cross flow fan is also conceivable.

However, in order to perform a normal air blowing operation using the cross flow fan, it is necessary to bend a flow path of air in the air conditioning unit from the air intake port to the air outlet port (hereinafter, also referred to as "in-unit flow path"). Therefore, a relatively large space is required for disposing the flow path in the body, and layout constraints are also imposed on the air intake port and the air outlet port.

When a cross flow fan is used for the thin air conditioner described in patent document 1, it is necessary to arrange the in-casing flow path in consideration of how to ensure a space for the in-casing flow path in the casing of the air conditioner in which it is difficult to obtain a sufficient height dimension in the vertical direction. In other words, a cross flow fan is used as the air supply source, but it is an issue to reduce the height of the air conditioner.

The invention aims to reduce the height of an air conditioner using a cross flow fan as a blowing source.

Solution for solving the technical problems

The air conditioner of the present invention comprises: a housing having an air inlet and an air outlet respectively arranged on a surface intersecting a horizontal plane and on a surface on the opposite side; a heat exchanger disposed between the air introduction port and the air outlet port; a cross flow fan disposed closer to the air outlet than the heat exchanger; and a driving unit that drives a driving source of the cross-flow fan so that a rotation direction of a region above the rotation axis is a direction from the heat exchanger toward the blowout port.

The air conditioner of the present invention comprises: a housing having an air inlet and an air outlet respectively arranged on a surface intersecting a horizontal plane and on a surface on the opposite side; a heat exchanger disposed between the air introduction port and the air outlet port; a cross flow fan disposed closer to the air outlet than the heat exchanger; a drive unit that drives a drive source of the cross-flow fan so that a rotation direction of a region above a rotation axis is a direction from the heat exchanger toward the blowout port; and a flow adjustment unit that generates an air flow from the obliquely downward direction toward the cross flow fan on the air intake side and generates an air flow from the cross flow fan to the obliquely downward direction on the blowout port side.

The radiation air conditioning device of the present invention includes: the air conditioner installed on the ceiling; a back panel mounted adjacent to the air conditioner outlet on the ceiling surface; a ventilation radiation panel having a horizontal projection area larger than an area where the air conditioner and the rear panel are combined; and a pair of side walls interposed between the back panel and the radiation panel in a direction in which the conditioned air is blown out from the air outlet.

Effects of the invention

According to the present invention, even if a cross flow fan is used as the air supply source, the height dimension of the air conditioner can be reduced.

1. Radiation air conditioning device

As shown in fig. 1, the radiation air-conditioning device 11 of the present embodiment is composed of an air conditioner 51 and a radiation panel unit 101, both of which are provided on a ceiling surface C. The radiation air conditioning device 11 is disposed near a wall surface W provided on one surface of the room R.

In the present embodiment, the directions of the air conditioner 51 and the radiation panel unit 101 are defined as follows. First, a horizontal plane is envisaged. The horizontal plane is not a horizontal plane which can exist as a living body, but is an abstract and conceptual virtual horizontal plane.

One surface intersecting such a horizontal plane and the opposite surface are referred to as the back surface and the front surface of the air conditioner 51. The back surface is a surface provided with an air introduction port 52 (see fig. 1 and 3) described later. The front surface is a surface on which a blow-out port 55 (described later) is arranged (see fig. 1 and 4).

When the air conditioner 51 is viewed from the front side, the surface intersecting the horizontal plane is a side surface. The right side surface is a right side surface, and the left side surface is a left side surface.

The upper and lower surfaces of the air conditioner 51 are upper surfaces, and the upper surface in the vertical direction is a lower surface.

When the air conditioner 51 is viewed from the front side, the direction connecting the both side surfaces is defined as the lateral width direction (width direction), the direction connecting the front surface and the rear surface is defined as the depth direction, and the direction connecting the upper surface and the lower surface is defined as the height direction. The front side is also referred to as a front side, and the back side is also referred to as a back side.

As shown in fig. 1, the radiation panel unit 101 is disposed adjacent to the front surface of the air conditioner 51. When such an arrangement relationship is maintained, the surfaces (end portions) and directions of the radiation panel unit 101 are defined in the same manner as those described above with respect to the air conditioner 51. The plane (end) and direction of the radiation panel unit 101 thus defined are uniquely determined and do not change even if the arrangement relationship shown in fig. 1 in which the radiation panel unit 101 is adjacent to the air conditioner 51 is broken.

Regarding the air conditioner 51, a case 51a of the air conditioner 51, a panel base 111 (back panel 112, side wall 113) and a radiation panel 131 (frame 132, cloth cover 141) constituting the radiation panel unit 101, which will be described later, are also similar to the radiation panel unit 101. That is, when the radiation panel unit 101 is in the state of fig. 1 adjacent to the front surface of the air conditioner 51, the surfaces (end portions) and directions of the respective portions are defined in the same manner as those described above for the air conditioner 51. The respective surfaces (end portions) and directions of the respective portions thus defined are uniquely determined and do not change even if the arrangement relationship shown in fig. 1 in which the radiation panel unit 101 is adjacent to the air conditioner 51 is broken.

(1) Air conditioner

The ceiling surface C is a folded ceiling, and has a recess C1 (see also fig. 18 and 19). The air conditioner 51 is attached to the pit C1 by, for example, an eye bolt (see fig. 18).

As shown in fig. 1, the air conditioner 51 introduces air in the room R from an air introduction port 52 provided in the rear surface, brings the air into contact with a heat exchanger 53, and then blows out the air as air-conditioned air from a blowout port 55 by a cross flow fan 54. A filter 56 is detachably attached to the air introduction port 52.

(a) Appearance of

As shown in fig. 2 to 6, the casing 51a of the air conditioner 51 has a thin shape in which the dimensions become smaller in the order of lateral width, depth, and height.

As shown in fig. 3, the air intake port 52 disposed on the back surface of the case 51a has three horizontally aligned regions each having a rectangular cross section. Each of the air introduction ports 52 is opened at a respective region so that the space on the indoor R side is connected to the inner space of the housing 51a.

Filters 56 are respectively installed at regions of three portions of the air introduction port 52. These filters 56 are attached to the housing 51a so as to be removable by a work from the lower surface side. The rear region of the housing 51a includes a structure that enables attachment of the filter 56 by pressing from below to above and removal of the filter 56 by pulling out from above to below. This structure includes a structure for guiding the filter 56 in the up-down direction and a structure for holding the filter 56 at a position where the air introduction port 52 is blocked.

The areas of the three portions serving as the air introduction ports 52 are disposed near the right side surface of the case 51a (see fig. 2 and 5). Therefore, when viewed from the back side, the areas of these three places are close to the left side.

As shown in fig. 4, the air outlet 55 arranged on the front surface of the casing 51a has three areas having a rectangular cross section arranged in parallel in the horizontal direction. The three regions are arranged near the right side in the lateral direction of the housing 51a in such a manner that the positions of the three regions are matched with the positions of the three regions serving as the air introduction ports 52 (see fig. 2 and 5).

The number of three portions to be the air outlet 55 and the arrangement of the air outlet 55 to the right are merely one embodiment. The implementation is not limited to this, and the air outlet 55 may be divided into a plurality of areas, or may be divided into two areas or four or more areas. The air outlet 55 may be disposed near the left side surface of the case 51a or may be disposed at the center. It is not necessary to dispose the air intake port 52 and the air outlet port 55 close to the same side of the housing 51a, and for example, the air intake port 52 may be disposed to the left, and the air outlet port 55 may be disposed to the right or the center.

As shown in fig. 2 and 4 to 6, the air outlet 55 is provided at the front end of the cover 61 having a shape protruding from the front surface of the housing 51 a. The areas of the three portions of the blow-out port 55 are divided by a partition plate 62 provided vertically in the cover 61. The partition plate 62 is not required in the case where the blowout port 55 is not divided into a plurality of areas.

The root side of the upper surface of the cover 61 connected to the front surface of the housing 51a is an inclined surface 63. Such an inclined shape is similar not only to the outer surface but also to the inner surface of the cover 61 (see fig. 9), and an inclined inner surface 64 inclined is provided on the upper surface of the cover 61 corresponding to the inclined surface 63.

In the air conditioner 51 mounted so as to be fitted in the recess C1 of the ceiling surface C, the cover 61 protrudes toward the panel base 111 side than the edge E that is the boundary between the ceiling surface C and the recess C1. At this time, the inclined shape of the inclined surface 63 of the cover 61 contributes to smooth connection with the panel base 111 described later.

The inclined shape of the inclined inner surface 64 of the cover 61 helps to ensure a normal operation of the cross flow fan 54 described later.

The contribution of these inclined surfaces 63 and inclined inner surfaces 64 will be described later.

As shown in fig. 2 to 6 and 8, guide rails 57 are attached to both side surfaces of a casing 51a of the air conditioner 51. The mounting positions of the pair of guide rails 57 are positions relatively lower on the rear side of the housing 51 a.

As shown in fig. 7, the guide rail 57 extends along the arrangement direction (depth direction) of the air conditioner 51 and the panel base 111, and has a stepped portion 57a. The step 57a is low in height on the panel base 111 side and high in height on the air conditioner 51 side.

The pair of left and right guide rails 57 are used for mounting the radiation panel unit 101 to the radiation air conditioning device 11. Details will be described later.

As shown in fig. 3, 5 to 6, and 8, a pair of magnets MG are provided on both end sides of the back surface of the casing 51a of the air conditioner 51.

As shown in fig. 8, the magnet holder 71 protrudes from the rear surface of the case 51 a. The magnet MG is mounted on the lower surface of the magnet frame 71.

The pair of right and left magnets MG are used for mounting the radiation panel unit 101 to the radiation air conditioning device 11. Details will be described later.

(b) Internal structure

Referring to fig. 9, the air intake port 52 provided on the back side and the air outlet 55 provided on the front side of the housing 51a are disposed on a surface intersecting the horizontal plane and on the opposite side.

The case 51a is provided with a heat exchanger 53 between the air intake port 52 and the air outlet 55, and a cross flow fan 54 on the air outlet 55 side of the heat exchanger 53. The air intake port 52, the heat exchanger 53, the cross flow fan 54, and the blowout port 55 are provided on a straight line in the depth direction.

The cross flow fan 54 rotates about the rotation axis a. In such a case 51a, a flow path of air (hereinafter also referred to as "in-body flow path 81") is provided, and the flow path of air is configured to introduce air in the room R from the air intake port 52 by rotation of the cross flow fan 54, and to cause the introduced air to come into contact with the heat exchanger 53 and blow out from the blowout port 55.

The cross flow fan 54 is not expected to perform only the irregular placement in the flow passage 81 in the body, that is, the air is sucked from the air intake port 52 and discharged to the air outlet 55. In order to generate an airflow in such a direction (see the arrow in fig. 9), the following conditions must be provided:

the in-vivo flow path 81 is curved

A cross flow fan 54 is disposed at a predetermined position in the body flow path 81

The crossflow fan 54 rotates in a direction matching the shape of the in-body flow path 81.

Therefore, in the present embodiment, there is provided: a structure for rotating the cross flow fan 54 in a predetermined direction; and an airflow adjuster 82, the airflow adjuster 82 generating an airflow from the air intake port 52 toward the blow-out port 55 by rotation of the cross-flow fan 54.

Detailed description will be made.

(rotation direction of Cross flow Fan)

As shown in fig. 2 to 5, the air intake port 52 and the air outlet port 55 are disposed on the right side of the casing 51a of the air conditioner 51. Thereby, a space is created on the left side of the housing 51a, which is independent of the flow of air connecting the air intake port 52 and the air outlet 55. The air conditioner 51 disposes an electrical structure in the space.

As shown in fig. 9, the electric structure is a driving portion DR and a control portion CR that drive a motor M as a driving source of the cross flow fan 54. The control unit CR controls all operations of the air conditioner 51, including the operation of the driving unit DR.

In fig. 9, the driving unit DR controlled by the control unit CR drives the cross flow fan 54 to rotate in the clockwise direction. The clockwise direction in fig. 9 is a direction in which the rotation direction of the upper half side of the cross flow fan 54, that is, the region above the rotation axis a, is directed from the heat exchanger 53 toward the blowout port 55.

(shape of flow passage in housing and arrangement of Cross-flow Fan)

As shown in fig. 10, the heat exchanger 53 passes the refrigerant tube 53b through a plurality of aluminum plates 53a arranged in the vertical direction. The temperature of the refrigerant is thermally conducted to the aluminum plates 53a by passing the refrigerant through the inside of the refrigerant tube 53b, and the temperature of the air passing through the slits 53c formed between the aluminum plates 53a is controlled.

The heat exchanger 53 of the present embodiment has three layers. That is, three heat exchangers 53 to be one layer of one unit are directly arranged.

The three-layer heat exchanger 53 is fixed in the housing 51a in an inclined state. The inclined direction is a direction in which one side surface of the cross flow fan 54 faces downward.

As shown in fig. 9, the air passing through the slit 53c of the heat exchanger 53 travels in a direction orthogonal to the face of the heat exchanger 53. Thereby, an air flow directed obliquely downward from the heat exchanger 53 is generated.

The airflow adjuster 82 causes the air that is perpendicular to the surface of the heat exchanger 53 and directed downward to follow the bottom surface in the housing 51a, and draws the air flowing along the bottom surface by the cross flow fan 54. The drawn air is directed toward the cross flow fan 54 from obliquely below.

In order to generate such an air flow, the air conditioner 51 is provided with two air flow adjustment plates 83 around the cross flow fan 54, and changes the traveling direction of the air from the heat exchanger 53 to the obliquely lower direction to the obliquely upper direction, and changes the air flow from the obliquely lower direction to the cross flow fan 54. The two airflow adjustment plates 83 are arranged so as to sandwich the cross flow fan 54 with a slight gap therebetween from the up-down direction, so that the airflow from obliquely below is introduced into the cross flow fan 54.

The airflow adjuster 82 connects the cross-flow fan 54 and the blowout port 55 by a cavity member forming a space inclined downward from the cross-flow fan 54 toward the blowout port 55. Used as the cavity member are the air flow adjustment plate 83 and the cover 61 in two upper and lower pieces.

The airflow adjusting plates 83 of the upper and lower plates are inclined obliquely downward with respect to the body flow path 81 on the side of the blowout port 55 of the cross flow fan 54. As a result, the in-body flow path 81 generates an air flow obliquely downward from the cross flow fan 54 at the air outlet 55.

More specifically, the in-body flow passage 81 guides the air introduced from the heat exchanger 53 side to the cross flow fan 54 to the blow-out port 55 side by bending the air by 90 °. Thus, the operation of the cross flow fan 54 is normally performed in which air is sucked from the air intake port 52 and discharged to the air discharge port 55.

The inclined inner surface 64 of the cover 61 has a shape inclined obliquely downward. The inclined inner surface 64 having such a shape serves as a part of the in-body flow path 81 on the blow-out port 55 side of the cross flow fan 54, and contributes to ensuring normal operation of the cross flow fan 54.

(2) Radiation panel unit

The radiation panel unit 101 is composed of a panel base 111 and a radiation panel 131.

(a) Panel base

As shown in fig. 11, the panel base 111 is a heat insulating member in the shape of a pair of side walls 113 standing from both side portions of a flat plate-shaped back panel 112 having a rectangular shape. For example, foamed styrene (EPS), resin, gypsum, polyurethane, glass wool, asbestos, or the like can be used as a material of the panel base 111.

The pair of side walls 113 are erected from both end portions in the longitudinal direction (width direction) of the back surface panel 112, that is, both side ends, and are wound slightly in the width direction along the longitudinal direction. Based on such a shape, three surfaces of the region on one end side, the region on the other end side, and the region facing the back surface panel 112 of the pair of side walls 113 are open.

For convenience of explanation, the region on one end side of the pair of side walls 113 is referred to as an inlet 114, the region on the other end side is referred to as an outlet 115, and the region facing the rear surface panel 112 is referred to as an opposite region 116. The facing region 116 is a region in a plane including upper end surfaces of the pair of side walls 113.

Accordingly, the panel base 111 includes a side wall 113 as a wall portion that is formed by taking the rear panel 112 as a base and is erected in a surrounding manner from the rear panel 112. An inlet 114 and an outlet 115 are provided between the pair of side walls.

The inlet 114 of the panel base 111 has a shape inclined toward an end edge connected to the outlet 55 of the air conditioner 51. The shape matches the inclined surface 63 of the cover 61 having the outlet 55 at the tip.

The panel base 111 having such a structure is attached to the ceiling surface C so that the position of the edge that becomes the inlet 114 matches the position of the edge E that becomes the boundary between the ceiling surface C and the pit C1. Thus, the inclined surface 63 of the cover 61 of the air conditioner 51 is aligned with the inlet 114 of the panel base 111, and the air outlet 55 and the inlet 114 are connected (see fig. 19).

The manner of mounting the panel base 111 to the ceiling surface C is not limited to this type. For example, screw fixation, surface fasteners, adhesive tapes, adhesion, or the like may be used, or attachment methods such as eye bolts may be used depending on the structure of the ceiling surface C.

A pair of stoppers 117 is provided on the panel base 111 so as to be located at the discharge port 115. Thus, the discharge port 115 is divided into three portions, that is, one portion on the center side of the width and two portions on the both sides of the width. These stoppers 117 are constituted by stopper metal fittings 119 fixed to the back panel 112.

The stopper metal fitting 119 functions as a coupling member, and thus a coupling groove 119a is provided.

Such a panel base 111 is integrally molded, for example, from EPS. Therefore, the whole functions as a heat insulating material.

(b) Radiation panel

As shown in fig. 12 to 14, the radiation panel 131 is formed by covering a rectangular frame 132 with a cloth cover 141, which is a bag-like cloth.

The frame 132 is formed in a rectangular shape that connects the plurality of rod-like members 133 and has ribs for reinforcing and preventing rotation. For the rod-like member 133, a part is used as an outer frame member 133a of a rectangular shape constituting the outer shape of the determination frame 132, and the other part is used as a reinforcing member 133b reinforcing the outer frame. As an example, a prismatic aluminum pipe having a hollow structure is used as the rod-shaped member 133, and these aluminum pipes are connected or screwed with a resin-made connector, thereby constituting the frame 132.

As another example, the rod-shaped member 133 may be formed of resin or carbon.

Such a frame 132 includes a first frame 134 and a second frame 135.

The first housing 134 is disposed in a region facing the air conditioner 51. The width of the first housing 134 is set to be wider than the air conditioner 51.

The second frame 135 has a width direction and a depth direction that are larger than those of the panel base 111, and a rear end side in the depth direction is a length up to a rear portion in the depth direction of the lower surface of the air conditioner 51.

The first housing 134 is coupled to the rear end of the second housing 135 by a hinge 136, and is rotatable with respect to the second housing 135 (see fig. 12 to 13 and 16). The rear end portions in the depth direction of the first frame 134 and the second frame 135 are each sized to completely cover the air conditioner 51.

As shown in fig. 13 to 14, the cloth cover 141 has a bag shape like a quilt cover. Is in the shape of an open edge 142 having four sides closed and capable of opening to three sides. A clip 143 is attached to the open edge 142, and the clip 143 can be opened and closed freely. By opening the opening edge 142, the housing 132 can be housed. The open edge 142 is positioned slightly inward of the end of the cloth cover 141.

The cloth cover 141 is formed from cloth, that is, fiber, and has air permeability and stretchability.

The cloth cover 141 is formed to be slightly smaller than the frame 132 in the width direction and the depth direction, and maintains a stretched state when the frame 132 is stored.

The shape of the cloth cover 141 like a bag can be regarded as a ring shape when viewed as a shape wrapping the frame 132 in the width direction. This is because the shape of the ring with both ends open and both ends closed is a bag.

The bag-shaped cloth cover 141 has a structure in which the fiber raw material exposed on the front surface side of the indoor R side is sewn to the fiber raw material on the back surface side facing the flow path 151. For convenience of explanation, the fiber material on the front side is referred to as front fiber 141A (see fig. 29 and 30), and the fiber material on the back side is referred to as back fiber 141B.

When the radiation panel 131 is provided, the surface fiber 141A is exposed to the indoor R side, and the appearance of the radiation air conditioning device 11 is determined. Accordingly, aesthetic considerations are important in selecting the material of the surface fibers 141A.

The back surface fibers 141B are selected from the viewpoint of avoiding resistance to the air flow as much as possible when the air flow blown out from the air outlet 55 of the air conditioner 51 is directed to the back side of the front surface fibers 141A. From this point of view, in the present embodiment, the mesh cloth, that is, the fibers of the mesh raw material are used as the back surface fibers 141B.

As shown in fig. 13 and 14, the front surface fibers 141A are wound around the back surface side facing the back surface panel 112, and are sewn to the back surface fibers 141B on the back surface side. The cloth cover 141 positions the stitched portion SP so as to be aligned with the pair of side walls 113 when the radiation panel 131 is assembled to the panel base 111.

In the radiation panel 131 in which the cloth cover 141 is covered on the frame 132, the first frame 134 and the second frame 135 are rotatable about the axis passing through the hinge 136, so that the rotation is free even in a state where the cloth cover 141 is covered. Therefore, for convenience of explanation, the portion of the radiation panel 131 where the first frame 134 is covered by the cloth cover 141 is referred to as a first panel 131A, and the portion of the radiation panel 131 where the second frame 135 is covered by the cloth cover 141 is referred to as a second panel 131B.

The first panel 131A assumes an area facing a part of the air conditioner 51.

The second panel 131B occupies a region facing the rest of the air conditioner 51 and the entire surface of the panel base 111.

As shown in fig. 1, the radiation panel 131 is positioned and secured to the opposite region 116 of the panel base 111. Thus, a space from the inlet 114 to the outlet 115 is defined, which becomes the flow path 151 of the air-conditioning air.

As schematically shown in fig. 15 (a), the radiation panel 131 in a state where the cover cloth 141 is attached to the frame 132 is formed in a hollow shape having one surface formed by the front surface fibers 141A and the opposite surface formed by the back surface fibers 141B. At this time, the radiation panel 131 is formed such that the back surface fibers 141B of the cloth cover 141 are mesh cloth, and thus have openings O on the back surface side. Accordingly, the air-conditioning air flowing through the flow channel 151 freely enters the inside of the radiation panel 131 from the back surface fibers 141B, and contacts the inside of the front surface fibers 141A. Accordingly, the surface fiber 141A having air permeability originally functions as the radiation surface RS.

As described above, the projection area of the frame 132 of the radiation panel 131 is larger than the air conditioner 51 and the panel base 111. More specifically, the width of the first frame 134 is set to be wider than the air conditioner 51, and the width and depth of the second frame 135 are set to be larger than the width and depth of the panel base 111. Accordingly, the radiation panel 131 has a horizontal projection area larger than the combined area of the air conditioner 51 and the panel base 111.

At this time, as schematically shown in fig. 15 (a), the radiation surface RS on the front surface fiber 141A side is wider than the rear surface 112 in terms of the above-mentioned dimensional relationship because the radiation surface 131 is hollow by the cover 141 covering the frame 132.

In contrast, the opening O is narrower than the width of the rear panel 112 corresponding to the relative interval between the pair of side walls 113. In other words, the pair of side walls 113 are interposed between the back surface panel 112 and the radiation panel 131 in the direction in which the air-conditioning air is blown out from the air outlet 55 of the air conditioner 51, and are installed between and opposed to the back surface panel 112 and the radiation panel 131 so that the opening O does not protrude. Thus, the width of the air-conditioning air flow path 151 is defined by the pair of side walls 113, and is connected to the inner space of the radiation panel 131 so that the air-conditioning air is not leaked to the outside from the opening O.

As schematically shown in fig. 15 (b), a rod-like member 133 of a frame 132 is positioned in the inner space of the radiation panel 131. Of these rod-like members 133, an outer frame member 133a of the first housing 134 and an outer frame member 133a of the second housing 135 are positioned immediately below the heat exchanger 53 incorporated in the air conditioner 51 in the vertical direction. The lower surface of the casing 51a of the air conditioner 51 is a flat surface, and the casing 132 is brought into close contact with each other via the cloth cover 141.

The outer frame member 133a of the second frame member 135 coupled to the first frame member 134, out of the first frame member 134 and the second frame member 135, which are in close contact with the lower surface of the housing 51a, functions as a rod-shaped close contact member RM. The rod-shaped close contact member RM is a part of the outer frame member 133a, and is in close contact with the casing 51a of the air conditioner 51 via the cloth cover 141. Closely contacting is the lower surface of the housing 51 a. The structure for bringing a part of the outer frame member 133a, which is the close contact member RM, into close contact with the housing 51a will be described later.

Such close contact member RM segments the inner space of the radiation panel 131, preventing the air-conditioning air from being wound on the rear side (side of the air introduction port 52) of the air conditioner 51 than the heat exchanger 53.

(c) Mounting/dismounting structure of radiation panel relative to panel base

As shown in fig. 12 to 14, 16 (a), and 16 (b), the frame 132 is provided with a pair of sliders 137, a pair of coupling pins 138 as coupling members, and a pair of suction plates 139 as suction members, as structures for pre-fastening and fixing the radiation panel 131.

The pair of sliders 137 cooperate with the pair of guide rails 57 to pre-fasten the radiation panel 131.

The pair of coupling pins 138 cooperate with the stopper 117 to fix the radiation panel 131.

The pair of attraction plates 139 cooperate with a magnet MG described later to hold the first panel 131A of the radiation panel 131.

(prefastening Structure of radiation Panel)

As shown in fig. 2 to 5, 7 to 8, 12 to 14, and 16 (a) and 17, the pre-fastening structure of the radiation panel 131 is constituted by a pair of guide rails 57 and a pair of sliders 137.

The pair of sliders 137 are fixed to the outer frame member 133a which becomes the close contact member RM of the second frame 135. The fixed positions are positions near both ends of the outer frame member 133a.

The slider 137 is fixed with a round bar-shaped pin 137b to a plate 137a for screw-fixing to the outer frame member 133a. The sheet 137a positions the pins 137b at a position higher than the outer frame member 133a. The pins 137b are arranged along the width direction of the radiation panel 131, that is, along the rotation axes of the first and second housings 134 and 135.

The relative interval of the pins 137b of the pair of sliders 137 is set to be slightly wider than the lateral width dimension of the housing 51a of the air conditioner 51. Accordingly, the pair of sliders 137 can be guided from above the pair of guide rails 57, and the pins 137b can be placed on the guide rails 57 (see fig. 20 and 21).

The pin 137b mounted on the rail 57 is slidably movable on the rail 57. At this time, the pins 137b pass over the stepped portions 57a, and the height of the slider 137, in other words, the height of the radiation panel 131 is varied. When the slider 137 moves from the panel base 111 side to the air conditioner 51 side, the radiation panel 131 is positioned at the high position. When the slider 137 moves from the air conditioner 51 side to the panel base 111 side, the radiation panel 131 is positioned at the low position. The radiation panel 131 positioned at the high position brings the outer frame member 133a of the second frame 135, which is the close contact member RM, into close contact with the casing 51a of the air conditioner 51 via the cloth cover 141.

As shown in fig. 2 to 5 and fig. 7 to 8, restricting pieces 57b are provided at both ends of the guide rail 57, respectively. These restricting pieces 57b prevent the pin 137b slidably moving on the guide rail 57 from coming off.

(formal fixing Structure of radiation Panel)

As shown in fig. 11 to 14 and (b) of fig. 16, the main fixing structure of the radiation panel 131 is composed of a pair of stoppers 117 and a pair of coupling pins 138.

A pair of coupling pins 138 are fixed to the second frame 135. The fixing position is a pair of reinforcing members 133b connected to the outer frame member 133a connected to the opposite side of the first housing 134. In these reinforcing members 133b, the connecting pins 138 are attached to relatively close positions of the outer frame member 133 a.

The pair of coupling pins 138 have a stud shape that is fitted into coupling grooves 119a of the pair of right and left stoppers 117 provided in the panel base 111. The coupling groove 119a is located at the discharge port 115 of the radiation panel unit 101 and opens to the indoor R side. Therefore, the coupling pin 138 is fitted into the coupling groove 119a of the stopper 117 by the horizontal movement of the radiation panel 131 from the panel base 111 toward the air conditioner 51.

Therefore, the stopper 117 and the coupling pin 138 constitute a coupling portion CN that is detachably coupled in accordance with the movement of the air conditioner 51 and the panel base 111 in the arrangement direction (depth direction).

(retaining Structure of first Panel)

As shown in fig. 1, 3, 5, 8, 12 to 14, and 16 (a), the holding structure of the first panel 131A is constituted by a pair of magnets MG (panel holding portion) and a pair of suction plates 139 (suction members).

The pair of suction plates 139 are fixed to the two reinforcing members 133b provided in the first housing 134. The fixed position is a position slightly lower than the pin 137b of the slider 137 in a state where the first housing 134 and the second housing 135 are disposed in the same plane. The suction plates 139 are horizontally positioned with respect to the flat suction surfaces 139a in a state where the first housing 134 is horizontally erected.

As described above, the pair of magnets MG are provided on both end sides of the back surface of the air conditioner 51, and are mounted downward.

The magnets MG and the attraction plate 139 are positioned such that, when the first panel 131A is horizontally erected in a formally fixed state on the radiation panel 131, the attraction surface 139a of the attraction plate 139 faces the magnets MG and is attracted by magnetic force.

(study of cloth cover)

The frame 132 of the radiation panel 131 is provided with a structure for attaching and detaching the radiation panel 131 to and from the panel base 111, and thus has irregularities. The concave-convex is a portion of the slider 137, the connection pin 138, and the suction plate 139.

If the cloth cover 141 is configured to cover these portions together with the housing 132, not only is the attachment and detachment of the cloth cover 141 to and from the housing 132 complicated, but the functions of these portions cannot be normally exhibited.

Accordingly, the cloth cover 141 is provided with openings for exposure at the portions of the slider 137, the connection pins 138, and the suction plate 139 so that these portions can be exposed. The opening for exposure is not shown.

2. Order of arrangement

The procedure for installing the radiation air conditioning device 11 will be described.

(1) Arrangement of air conditioner

First, as shown in fig. 18, the air conditioner 51 is provided in a pit C1 provided in a ceiling surface C that is a folding ceiling.

If the pit C1 is provided in advance, the pit C1 is used, and if the pit C1 is not provided, the ceiling surface C is constructed to form the pit C1.

(2) Installation of panel substrates

As shown in fig. 19, a panel base 111 is attached to the ceiling surface C.

The panel base 111 is aligned and fixed to the ceiling surface C so that the inlet 114 is positioned at an edge E that is a boundary between the ceiling surface C and the pit C1.

At this time, the inlet 114 of the panel base 111 is positioned along the edge E that is the boundary between the ceiling surface C and the pit C1. As a result, the air outlet 55 of the air conditioner 51 is aligned with the inlet 114 of the panel base 111, and is connected to each other (see fig. 1).

(3) Mounting a radiation panel

(a) Prefastening

First, the radiation panel 131 is pre-fastened.

As shown in fig. 20 to 22, the pair of sliders 137 provided on the radiation panel 131 are brought close to the guide rails 57 provided on both side portions of the air conditioner 51, and the sliders 137 are placed on the guide rails 57, whereby the radiation panel 131 is pre-fastened. The slider 137 is placed at a low level in front of the guide rail 57.

The positions of the second frame 135 and the first frame 134 are not limited and the radiation panel 131 in the pre-fastened state is rotatable.

(b) Rotation of the second panel

As shown in fig. 23 to 24, if the radiation panel 131 is pre-fixed, the second panel 131B is rotated to be horizontal.

At this time, the pair of sliders 137 are placed at a low level of the pair of guide rails 57. The joining pin 138 of the second panel 131B is in a state of facing the stopper metal fitting 119 of the panel base 111 at a spaced-apart interval.

(c) Formally fix

As shown in fig. 25 to 26, if the second panel 131B is horizontal, the second panel 131B is pushed in while maintaining the posture. That is, the radiation panel 131 is moved in the direction of the air conditioner 51.

Thereby, the coupling pin 138 is fitted into the coupling groove 119a of the stopper fitting 119, thereby positively fixing the radiation panel 131.

At this time, the slider 137 slides on the guide rail 57 and is positioned at a high position beyond the step portion 57 a. Thereby, the end side of the second panel 131B connected to the front end side of the radiation panel 131, that is, the first panel 131A, is lifted up and pressed against the lower surface of the casing 51A of the air conditioner 51. As a result, the outer frame member 133a of the second frame 135, which becomes the close contact member RM, is brought into close contact with the lower surface of the housing 51a via the cloth cover 141.

When the radiation panel 131 is fixed formally, the first panel 131A is freely rotated by the hinge 136 and hangs down in the vertical direction.

(d) Retaining of the first panel

As shown in fig. 27 to 30, the first panel 131A is rotated to the horizontal.

Then, the suction surface 139a of the suction plate 139 provided on the first panel 131A is attracted by the magnet MG provided on the back surface of the air conditioner 51 by the magnetic force, and is sucked to the magnet MG through the cloth cover 141. Thereby, the first panel 131A is held, and a horizontal state is ensured.

The first panel 131A ensures a horizontal state, whereby the cloth cover 141 is stretched by the first frame 134 and ensured to be in a stretched state.

Thus, the mounting operation of the radiation panel 131 is completed.

(4) Removal of the radiation panel

(a) Holding release of first panel

As shown in fig. 29, the first panel 131A is rotated against the attractive force of the attraction plate 139 generated by the magnetic force of the magnet MG.

Then, as shown in fig. 25 to 26, when the hand is released, the first panel 131A is freely rotated and hangs down in the vertical direction.

(b) Connection release of connection part

The second panel 131B is held and stretched from the state shown in fig. 25 to the state shown in fig. 23. That is, the radiation panel 131 is moved from the air conditioner 51 toward the panel base 111.

Thereby, the coupling pin 138 is disengaged from the coupling groove 119a of the stopper fitting 119, and the main fixing of the radiation panel 131 is released.

At this time, the slider 137 slides on the guide rail 57 and is positioned at a low height beyond the step portion 57 a. Thereby, the position of the end side of the radiation panel 131, that is, the end side of the second panel 131B connected to the first panel 131A is also lowered and separated from the lower surface of the casing 51A of the air conditioner 51. As a result, the state in which the outer frame member 133a of the second frame 135, which is the close contact member RM, is brought into close contact with the lower surface of the housing 51a via the cloth cover 141 is also released, and the radiation panel 131 is in the pre-fastened state.

(c) Rotation of the second panel

As shown in fig. 21 to 22, the second panel 131B is rotated from the pin 137B of the slider 137 placed on the guide rail 57 to be inclined.

(d) Shedding off

The second panel 131B is gripped at both ends thereof, and the slider 137 is lifted from the guide rail 57 to be released.

Thereby, the removal operation of the radiation panel 131 is completed.

3. Effects of action

When the air conditioner 51 is operated, the conditioned air is blown out from the air outlet 55, and flows from the inlet 114 to the outlet 115 through the flow path 151. Thus, the temperature of the radiation panel 131 can be adjusted by air-conditioning air. Heating and cooling. Thereby, the indoor R is subjected to radiation air conditioning.

(1) Dew condensation prevention

During cooling, the radiation air-conditioning device 11 of the present embodiment suppresses dew condensation on the radiation panel 131.

The reason for this will be described in detail.

(a) Cause of dew condensation

Moisture is contained in air as a gas (water vapor).

The state in which the air contains water vapor to the limit is referred to as a saturated state, and the amount of water vapor at this time is referred to as a saturated water vapor amount. The saturated water vapor amount varies depending on the air temperature, and the higher the air temperature is, the lower the air temperature is, and the smaller the air temperature is.

Therefore, when the air is gradually cooled, moisture in the form of water vapor at a high temperature is saturated in time and changed into liquid. That is, since the saturated steam amount decreases together with the decrease in the air temperature, if the air is continuously cooled, the steam is saturated and becomes liquid at a certain time.

The temperature at this time is referred to as dew point temperature.

The dew point temperature varies according to the amount of water vapor contained in the air, and the higher the amount of water vapor, the lower the amount of water vapor.

More specifically, the saturated vapor condenses due to the temperature lower than the dew point, and becomes water droplets adhering to the surface of the object. This is a phenomenon called dew condensation.

At this time, even if the air temperature is reduced from the same temperature, the condensation temperature is lower when the amount of water vapor contained is small than when the amount of water vapor contained is large. For example, when the air temperature starts to decrease in an environment of 25 ℃, condensation occurs at about 14 ℃ in the case of 50% of the saturated steam, whereas the condensation temperature is about 6.5 ℃ in the case of only 30% of the saturated steam.

(b) Radiation air conditioning device of this embodiment

In the radiation air-conditioning device 11 of the present embodiment, the air is dried by the cooling operation of the air conditioner 51 on the rear side divided by the radiation panel 131, that is, on the side where the flow path 151 of the air conditioner 51 is arranged, and the dried air is circulated. This is because, the air introduced into the room R of the air conditioner 51 from the air introduction port 52 is rapidly cooled when passing through the heat exchanger 53, and a part of the water vapor contained in the air is liquefied and removed.

Therefore, even if the saturated water vapor amount of the air passing through the air-conditioning air flow path 151 decreases due to a cooling operation, the dew point temperature of the air decreases due to drying, and dew condensation does not occur on the back surface of the radiation panel 131. More specifically, dew condensation does not occur in both the back surface fibers 141B and the front surface fibers 141A wound around the back surface side in the cloth cover 141.

On the other hand, the surface side of the radiation panel 131 is cooled by the cooling operation, and the air in the cooling chamber R is radiated. Therefore, the cloth cover 141, that is, the surface fiber 141A, located on the surface of the radiation panel 131 maintains a low temperature state, and thus the air in contact with the surface fiber 141A approaches the dew point temperature.

At this time, when the air in contact with the surface fibers 141A reaches the dew point temperature, the water vapor contained in the air becomes liquid.

(c) Principle of dew prevention

In contrast, in the present embodiment, the cloth cover 141 has air permeability.

Accordingly, the air passing through the air-conditioning air flow path 151 passes through the cloth cover 141 and leaks out to the front side of the surface fibers 141A exposed to the indoor R side. As a result, the dried air is in a state of being a layer on the front side of the surface fiber 141A.

Therefore, the dew point temperature of the air is lower than the temperature of the surface fibers 141A that have been lowered on the surface side of the surface fibers 141A where the dried air becomes a layer, and thus dew condensation does not occur.

Based on the above principle, according to the present embodiment, dew condensation on the surface of the radiation panel 131 can be avoided in various environments during cooling.

(2) Thinning of air conditioner

(a) Cross flow fan

The air conditioner 51 uses a cross flow fan 54 as a blowing source. When the cross flow fan 54 is used, the body flow path 81 needs to be curved, so that the height of the casing 51a is easily increased anyway.

In contrast, in the air conditioner 51 of the present embodiment, the in-housing flow path 81 is curved in a limited height dimension within the housing 51a by providing the air flow adjustment portion 82 including the inclined arrangement of the three-layer heat exchanger 53 and the pair of air flow adjustment plates 83. This makes it possible to arrange the air intake 52, the heat exchanger 53, the cross flow fan 54, and the blowout port 55 on a straight line.

Therefore, even if the cross flow fan 54 is used as the air supply source, the height dimension of the air conditioner 51 can be reduced. As a result, the radiation air-conditioning device 11 of the air-conditioner 51 can be covered with the radiation panel 131 along the ceiling surface C.

(b) Heat exchanger

The heat exchanger 53 inclines the surface of the side of the cross flow fan 54 obliquely downward, and causes the air flow passing through the heat exchanger 53 to travel obliquely downward. After that, the air flow is guided to the pair of upper and lower air flow adjustment plates 83, and the traveling direction is changed from obliquely downward toward the cross flow fan 54. Such a flow of the so-called V-shaped air contributes to the generation of an air flow that enables the cross flow fan 54 to function normally in the only distance between the heat exchanger 53 and the cross flow fan 54.

(3) Heat exchanger

The heat exchanger 53 has three layers. This can increase the area of the aluminum plate 53a contributing to heat exchange, and can obtain high heat exchange efficiency.

On the other hand, the air sucked by the cross flow fan 54 passes through slits 53c formed between the aluminum plates 53a of the heat exchanger 53. Therefore, if the number of layers of the heat exchanger 53 increases, the air resistance increases accordingly, and the amount of conditioned air blown out from the air outlet 55 decreases.

In contrast, in the present embodiment, this problem is solved by tilting the heat exchanger 53 in the housing 51 a. As described above, the air passes in the direction orthogonal to the face of the heat exchanger 53. Therefore, if the number of refrigerant tubes 53b is the same, the area of the slit 53c can be enlarged in an oblique direction with respect to the airflow, as compared with the case where the heat exchanger 53 is arranged in an orthogonal direction with respect to the airflow, and therefore, the corresponding air resistance can be reduced.

Such an inclined configuration of the heat exchanger 53 brings about another advantage of improvement in heat exchange efficiency. This is because the area of the aluminum plate 53a contacted by the air can be increased by tilting with respect to the air flow.

As described above, three effects are produced simultaneously by the three-layer heat exchanger 53 disposed obliquely.

The first effect is: since the operation of generating the V-shaped air flow on the downstream side of the heat exchanger 53 is performed, the air flow for normally functioning the cross flow fan 54 is generated.

The second effect is: the resistance applied to the air passing through the slit 53c is reduced, thereby preventing the reduction of the blowing amount of the air-conditioning air from the blowing-out port 55.

The third effect is: the area of the aluminum plate 53a contacted with the air is increased, and the heat exchange efficiency is improved.

(4) Amplification of heat radiation area

(a) Amplification in width direction

As shown in fig. 15 (a), the air-conditioning air flow path 151 is formed in a space between the rear panel 112 and the radiation panel 131 of the panel base 111. At this time, the width of the flow channel 151 is defined by the relative distance between the pair of side walls 113 provided on the panel base 111.

At this time, the relative interval of the pair of side walls 113 is determined by the width of the back panel 112. The relative spacing of the pair of side walls 113 does not expand beyond the width of the back panel 112. Therefore, the width of the air-conditioning air flow path 151 is not increased to be equal to or larger than the width of the rear panel 112.

In contrast, in the present embodiment, a hollow radiation panel 131 is used. The radiation panel 131 expands the internal space from the opening O in contact with the flow path 151 of the air conditioner, and forms a radiation surface RS on the side opposite to the opening O. The radiation surface RS has a horizontal projection surface wider than the width of the rear panel 112.

Therefore, according to the present embodiment, the heat radiation area of the radiation panel 131 can be enlarged beyond the flow path width of the air conditioning air defined by the pair of side walls 113. As a result, the heat radiation efficiency of the actual size or more can be obtained.

(b) Expansion of area overlapping with air conditioner

As shown in fig. 15 (b), the hollow radiation panel 131 has a hollow region from a position beyond the air outlet 55 of the air conditioner 51 to a position overlapping the air conditioner 51, and the radiation surface RS is also disposed in this region.

Therefore, the heat radiation area of the radiation panel 131 can be further enlarged.

Further, the expansion range of the heat radiation area is limited to an area where the close contact member RM generated by the outer frame member 133a of the second frame 135 is in close contact with the housing 51a of the air conditioner 51 via the cloth cover 141. The close contact member RM is disposed immediately below the heat exchanger 53 incorporated in the air conditioner 51 in the vertical direction, and therefore the entire area up to the close contact member RM serves as a heat radiation area, thereby achieving an improvement in heat radiation efficiency.

(5) Prevention of shortcut phenomena

As described above, by the configuration in which the hollow area of the radiation panel 131 is enlarged to a position overlapping with the air conditioner 51, the air-conditioning air blown out from the air outlet 55 of the air conditioner 51 is wound around the back surface side of the air conditioner 51, that is, the side where the air intake 52 is provided. At this time, if the air-conditioning air is wound around the back surface of the air conditioner 51, the air-conditioning air is introduced from the air introduction port 52, and a so-called shortcut phenomenon is caused. As a result, the operation efficiency of the air conditioner 51 is lowered, and thus, some countermeasure is required.

In this regard, in the present embodiment, the close contact member RM formed based on the outer frame member 133a of the second frame 135 prevents the flow of the air-conditioning air to prevent the occurrence of the shortcut phenomenon. When the radiation panel 131 is fixed (see fig. 27 to 30), the close contact member RM is in close contact with the casing 51a of the air conditioner 51 via the cloth cover 141, and blocks the flow of the air-conditioning air toward the rear surface side of the air conditioner 51 through the inside of the radiation panel 131.

In the present embodiment, when the first panel 131A is in the horizontal state (see fig. 27 and 30), the cloth cover 141 is stretched by the first frame 134 to be secured in the stretched state. Thus, the surface fibers 141A of the cloth cover 141 serving as the radiation surface RS are brought into close contact with the close contact member RM, and leakage of the air-conditioning air from between the close contact member RM and the surface fibers 141A can be prevented.

Thus, according to the present embodiment, it is possible to prevent a decrease in the operation efficiency of the air conditioner 51 caused by the shortcut phenomenon.

(6) Effects brought about by the shape and structure of the sheet

The cloth cover 141 has a bag shape for accommodating the frame 132.

Thereby bringing about the following operational effects.

(a) Expansion of heat radiation area

One effect is that it is easy to make the radiation panel 131 hollow.

As a result, it is easy to expand the heat radiation area of the radiation surface RS in the width direction to the area overlapping with the air conditioner 51.

(b) Make manufacture easy

Another effect is that the mounting of the housing 132 is easy, and the manufacturing of the radiation panel 131 can be facilitated.

(c) Eliminating the disadvantage

On the other hand, since the air-conditioning air passes through the two cloth covers 141 from the flow path 151 to the indoor R, the cloth cover 141 on the flow path 151 side becomes resistance to the air-conditioning air directed toward the cloth cover 141 on the indoor R side. At this time, if the resistance is excessively large, the operation of generating a layer of dry air-conditioning air in the area facing the indoor R of the cloth cover 141 is hindered.

Therefore, in the present embodiment, the opening O is provided on the surface of the cloth cover 141 facing the air-conditioning air flow path 151, and the mesh cloth is provided on the opening O.

More specifically, the cloth cover 141 is formed in a bag shape by a sewing structure of a fiber raw material (front fiber 141A) exposed on the front surface side of the indoor R side and a fiber raw material (back fiber 141B) facing the back surface side of the back surface panel 112. Accordingly, the back surface fiber 141B can be freely made of various materials and forms without being a body of the cloth cover 141. In the present embodiment, the use of the mesh-like material for the back surface fibers 141B reduces the resistance of the back surface fibers 141B against the air-conditioning air flowing from the flow path 151 toward the indoor R-side cloth cover 141.

Also, the stitched portions SP of the front and rear fibers 141A and 141B are aligned with the side walls 113. Thereby, when the radiation panel 131 is viewed from below, the stitched portion SP can be prevented from being seen through the surface fiber 141A.

(7) Make the assembly and disassembly of the radiation panel easy

According to the present embodiment, when the radiation panel 131 is attached and detached, the radiation panel 131 can be pre-fastened in an inclined state. Then, the radiation panel 131 is moved while being horizontally maintained, whereby the radiation panel 131 can be fixed formally.

Therefore, the mounting and dismounting operation of the radiation panel 131 can be facilitated.

In this case, in the present embodiment, the radiation panel 131 is divided into the first panel 131A and the second panel 131B, and when the radiation panel 131 is pre-fastened and fixed formally, the radiation panel 131 may be focused on the first panel 131A more than the radiation panel 131. This makes it possible to further facilitate the attachment and detachment of the radiation panel 131.

(8) Freedom of choice of material of sheet material

According to the present embodiment, the air-conditioning air blown out from the air outlet 55 of the air conditioner 51 is guided out from the outlet 115 into the room R. That is, the air-conditioning air does not need to be intentionally led out to the indoor R through the cloth cover 141.

Therefore, the cloth cover 141 does not require a characteristic for passing the air-conditioning air.

The cloth cover 141 is required to have substantially only air permeability of the degree of allowing air passing through the air-conditioning air flow path 151 to leak out to the indoor R side and generating a layer of dried air on the front side of the surface fibers 141A.

Therefore, according to the present embodiment, the range of material selection of the sheet can be widened.

(9) Inhibition of deformation of sheet material

According to the present embodiment, the cloth cover 141 of the radiation panel 131 is arranged along the direction in which the air-conditioning air blown out from the air outlet 55 flows through the flow path 151. Further, since the air flowing through the flow path 151 is discharged from the discharge port 115, the internal pressure in the flow path 151 does not rise.

Therefore, during operation of the radiation air-conditioning device 11, the deformation of the cloth cover 141 can be suppressed as much as possible without causing the flow of air and the rise of pressure that flex the cloth cover 141 of the radiation panel 131.

(10) Thermal efficiency

The panel base 111 is made of a heat insulating material, and is in a state equivalent to a state where heat insulating portions are provided on the rear panel 112 and the side walls 113.

Accordingly, the heat of the air-conditioning air flowing through the flow path 151 is not taken away by the panel base 111, and the cloth cover 141 can be effectively heated or cooled. As a result, the radiation air-conditioning device 11 excellent in thermal efficiency can be obtained.

Further, since the panel base 111 itself is molded from the heat insulating material, there is no complicated problem of separately preparing the heat insulating material and attaching it to the panel base 111, and it is possible to reduce the component cost and manufacturing cost of the panel base 111 and to facilitate manufacturing.

(11) Extra long appearance

(a) Attractive appearance

The air conditioner 51 is accommodated in a recess C1 provided in one surface (ceiling surface C) of the room R, and the panel base 111 is joined to one surface of the room R. Thus, in the indoor R, the radiation air-conditioning device 11 can be made thin and compact.

The radiation panel 131 also covers the air conditioner 51, and one side of the bag-shaped cloth cover 141 that is open is closed by the clip chain 143, so that the radiation air conditioner 11 appears to be a single radiation panel 131 disposed near the ceiling surface C in appearance. At this time, the radiation panel 131 is in a state where only the cloth cover 141 of the fiber raw material is exposed, and thus it appears to be soft in accordance with the human feeling and sensation.

Therefore, the radiation air-conditioning device 11 can be obtained in a refined appearance that does not cause any trouble or trouble when installed in the room R.

(b) Use and beauty

Considering the reason why the radiation air-conditioning device 11 appears to be a single radiation panel 131 disposed only in the vicinity of the ceiling surface C in its external appearance, the following three main causes are noted:

The base Yu Bugai 141 covers the frame 132, and the radiation panel 131 is hollow

The horizontal projection area of the radiation panel 131 is larger than the width of the rear panel 112

The horizontal projection area of the radiation panel 131 is larger than the combined area of the air conditioner 51 and the rear panel 112.

The relationship between the structure of the radiation panel 131 and the horizontal projection area of each portion is closely related to the "use" of the expansion of the heat radiation area. That is, the magnitude relation of the horizontal projection area such that the width of the radiation panel 131 is wider than that of the rear panel 112 contributes to the expansion of the heat radiation area of the radiation surface RS in the width direction. The size relationship of the horizontal projection area of the radiation panel 131 covering the air conditioner 51 helps to expand the heat radiation area of the radiation surface RS to the area overlapping the air conditioner 51. The expansion of the heat radiation area of the radiation surface RS is also said to depend on the structure of the radiation panel 131, which is hollow.

From the above observation, the external appearance of the radiation air-conditioning device 11 is "beautiful" connected to "use".

4. Modification examples

In practice, various modifications and changes can be made.

(1) Installation place of radiation air conditioning device

For example, in the present embodiment, the radiation air-conditioning device 11 is shown to be provided on the ceiling surface C, but may be configured to be provided on a surface different from the indoor room R, for example, the wall surface W (see fig. 1) when the radiation air-conditioning device is implemented. In this case, if the wall surface W is provided with a recess, and the air conditioner 51 is accommodated in the recess, the radiation air conditioner 11 can be realized in a flat shape that appears to be provided with the radiation panel 131 only on the wall surface W, as in the present embodiment.

(2) Setting state of radiation air conditioning device

Although an example in which the air conditioner 51 is housed in the pit C1 while the ceiling surface C is a folded ceiling is shown, this is not essential, and the air conditioner 51 may be provided on a flat ceiling surface C or a wall surface W. At this time, the air outlet 55 of the air conditioner 51 is likely to deviate from the ceiling surface C or the wall surface W, but by providing the radiation panel unit 101 so as to float from the ceiling surface C or the wall surface W, the inlet 114, which is an inlet of the flow passage 151, can be made to face the air outlet 55.

The method of attaching the air conditioner 51 to the ceiling surface C is not limited to the above-described eye bolt, and various methods can be adopted. For example, various deformations are allowed by fastening structures based on screws or the like, fastening structures using a face tape, press-fitting structures, and the like.

(3) Arrangement of air conditioner and back panel

In the present embodiment, the air outlet 55 of the air conditioner 51 and the back panel 112 of the panel base 111 are disposed adjacent to each other with a gap therebetween. In practice, the back panel 112 may be attached to the ceiling surface C adjacent to the outlet 55 of the air conditioner 51.

At this time, it is important that the inlet 114 of the panel base 111 is connected to the blowout port 55.

The term "connected" as used herein means that the air-conditioning air blown out from the air outlet 55 is guided to the inlet 114, and as long as this is the case, the air outlet 55 and the inlet 114 may be disposed separately, may be disposed in contact with each other, or may be disposed in a superposed manner. That is, the air conditioner 51 and the back panel 112 may be disposed separately, may be disposed in contact with each other, or may be disposed in a superposed manner.

(4) Structure of radiation panel

The radiation panel 131 is not necessarily limited to the structure in which the frame 132 is covered with the cloth cover 141, and may be, for example, a structure in which japanese paper is attached to the frame 132 or a structure in which the radiation panel is assembled by a plate having air permeability. If the radiation panel 131 has a hollow structure having the air permeable radiation surface RS on one surface and the opening O on the opposite surface, various materials and structures are allowed.

In the case where the frame 132 is covered with the cloth cover 141 as in the radiation panel 131 of the present embodiment, various modifications and changes are allowed to be made to the respective structures, shapes, materials, and the like of the frame 132 and the cloth cover 141. For example, the number and arrangement positions of the rod-like members 133 constituting the housing 132 are not limited to those described in the present embodiment, and various numbers and arrangements are possible.

(5) Fixing structure of radiation panel

(a) Mounting position of slider

In the present embodiment, a configuration example in which the slider 137 is attached to the second housing 135 is illustrated. In practice, the slider 137 is not limited to this configuration, and may be provided in a connection region between the first housing 134 and the second housing 135. For example, the slider 137 may be attached to the first housing 134. Alternatively, the hinge 136 is used as a member for connecting the first frame 134 and the second frame 135, but a larger member may be used as such a connecting member, and the slider 137 may be attached to such a large connecting member.

(b) Other fixing structures

In the present embodiment, the radiation panel 131 is fixed to the air conditioner 51 and the panel base 111 by the pair of sliders 137, the pair of connecting pins 138, and the pair of suction plates 139, and various structures can be adopted for fixing the radiation panel 131.

For example, a fixing structure based on only a magnet may be employed in accordance with the weight of the radiation panel 131.

(c) First panel

The structure for fixing the first panel 131A is not limited to the magnet MG, and various kinds of deformation are allowed, for example, a fastening structure by screws or bolts, a fastening structure using a surface tape, a press-fit structure, and the like.

(6) Form of radiation panel

In the above embodiment, the radiation panel 131 is exemplified as a flat plate shape, but various forms are allowed in practice.

For example, as shown in fig. 31 (a), the radiation panel 131 may have an arch shape that hangs down from both sides when viewed from the front. In this case, the planar shape of the radiation panel 131 may be a rectangular shape as shown in fig. 31 (b) or an elliptical shape as shown in fig. 31 (c), and various shapes are allowed.

The radiation panel 131 may be suspended from the ceiling surface C without being in close contact with the ceiling surface C, as shown in fig. 32.

(7) Side wall

In the above embodiment, the pair of side walls 113 are illustrated as rising from both side edges of the back panel 112. In this regard, the side wall 113 does not necessarily have to stand up from the side edge in the implementation, and may stand up from a position near the center side.

In the present embodiment, all the wall portions formed as the pair of side walls 113 are allowed as long as the wall portions stand up in a surrounding shape from the rear panel 112 while leaving the inlet 114 and the outlet 115.

Further, the pair of side walls 113 may not be integrated with the back panel 112 as long as they are interposed between the back panel 112 and the radiation panel 131.

(8) Discharge outlet

In the above embodiment, the example in which the discharge port 115 is provided in the region facing the inlet port 114 is shown, but various modifications and changes are allowed during the implementation. For example, the discharge port 115 may be provided in a part of the side wall 113, and in this case, the discharge port 115 may be distributed to a plurality of positions.

(9) Variation of the position of the chains of the sheet

The position of the clip 143 of the cloth cover 141 may be, for example, a position close to one side as shown in fig. 33 (b), a position closing three sides as shown in fig. 33 (c), or a V-shape as shown in fig. 33 (d), as in the above-described embodiment, and various embodiments are allowed.

(10) Another construction example of the radiation air-conditioning device

Fig. 34 is a front view showing another configuration example of the radiation air conditioning device 11.

In the embodiment shown in fig. 1 to 33 and the present modification, the side wall 113 is provided on the panel base 111, whereby a space for the flow passage 151 is secured between the rear surface panel 112 and the radiation panel 131. In this regard, the radiation panel unit 101 of the radiation air conditioning device 11 shown in fig. 34 secures a space for the flow passage 151 by the radiation panel 131.

Accordingly, the radiation panel 131 is provided with the frame 132 having a three-dimensional shape instead of a planar shape, thereby creating a space for the flow channel 151 with the rear surface panel 112. More specifically, the frame 132 is curved in a curved shape when viewed from the front and rear sides, and both end portions are connected and fixed to the rear panel 112. The cloth cover 141 is attached to the housing 132 so as to cover the room from the R side. The cloth cover 141 may be fixed to the frame 132 by, for example, fastening both side portions of the cloth cover 141 to both side portions of the frame 132. The cloth cover 141 is fixed to the frame 132 in a stretched state.

With such a structure, the panel base 111 does not have the side wall 113, but is mainly composed of the rear panel 112.

In the radiation panel unit 101 thus configured, the inlet 114 is formed on the back side, the outlet 115 is formed on the front side, and the air-conditioning air flow path 151 from the inlet 114 to the outlet 115 is formed between the back panel 112 and the radiation panel 131 of the panel base 111.

Thus, the operation and effect are achieved in common with the embodiments shown in fig. 1 to 33.
