Description

Blowing port for low temperature air conditioner
Technical field
The present invention relates to the multilayer taper blowing mouth that blows out by the runner that a plurality of cones square and that form ring-type is left the concentric shape configuration in compartment of terrain, air is formed each other from cone, especially relate to blowing port for low temperature air conditioner with function of blowing mouth generation dewfall when preventing to blow out Cryogenic air.
Background technology
As traditional idle call blowing mouth, known have a kind of blowing mouth, it is arranged on the ceiling of building under the state that the air duct with the ceiling back portion that is provided in building is connected, and has the Air Conditioning that will supply with by pipeline from air conditioner from the indoor function that blow out of ceiling to building.These idle call blowing mouths use the symmetric figure structure of the rectangular cone of the system that the is applicable to ceiling that has divergent contour and pay attention to indoor grade attractive in appearance.
These idle call blowing mouths, general different with the axial flow blowing mouth that blows out with respect to blowing actinal surface vertical direction, be the radially blowing mouth that dry in diffusion type ground on the horizontal direction of the actinal surface of drying.Therefore,, lure room air, dewfall takes place easily on the surface of blowing mouth from the Air Conditioning that blowing mouth blows out according to the configuring condition of indoor blowing mouth.
Such as, blowing out cold Air Conditioning from blowing mouth during refrigeration, blowing mouth itself cools off because of this cold blow out air, and room air is subjected to luring of this blow out air and arrives on the limit of blowing mouth.When the surface temperature of blowing mouth becomes dew-point temperature than room air when low, on the surface of blowing mouth dewfall takes place.
On the other hand, in recent years, adopt sometimes to blow out than traditional Air Conditioning low-temperature air conditioner mode of the air of low temperature more.In the low-temperature air conditioner mode, lower by the temperature that makes the air that blows out than traditional air-conditioner temperature, just can reduce air output, so pipeline pipe arrangement etc. is attenuated.Its result can reduce the ability of Air Blast fan, not only helps energy-conservationly, also can save spatialization by the thin footpathization of pipeline pipe arrangement.
Fig. 9 is the main cutaway view of traditional symmetric figure blowing mouth.As shown in Figure 9, traditional symmetric figure blowing mouth 70 leaves the concentric shape setting in compartment of terrain with 4 cones 71~74 that vary in size, and is provided with at the boundary vicinity of the oblique part 78 that is positioned at the most inboard inner cone 71 and longitudinal component 79 and covers plate 75.This coverage plate 75 is in order to can't see the inside of the blowing mouth 70 that is configured on the ceiling surface from the indoor of the below of blowing mouth 70, to be provided with the aesthetic appearance that improves blowing mouth 70.In addition, be positioned at outermost outermost cone 74 and be connected with chamber portion 76, this chamber portion 76 is connected with neck 77.
The flow passage that the cold air that blows out from blowing mouth 70 forms along cone 71~74 each other with air.As the blowing mouth of the coverage plate that structure like this has been installed, such as, have the blowing mouth of divergent contour structure (such as, with reference to patent documentation 1: Japan Patent is real opens flat 6-64049 communique, the 2nd page, Fig. 1-6).
In addition, also developed central authorities at blowing mouth and be provided with porous plate and substitute and cover plate, with the air-flow of the central portion of blowing mouth towards the blowing mouth of below guiding (such as, with reference to patent documentation 2: Japan Patent is real opens flat 7-12846 communique, the 2nd page, Fig. 1-3).
But, in described traditional blowing mouth 70, the plate 75 of coverage is arranged, because the air that blows out from blowing mouth 70 makes room air be lured by the medial surface of inner cone 71, in this part generation dewfall in the installed inside of inner cone 71.Such phenomenon can take place in the divergent contour blowing mouth of record in patent documentation 1 too, and the generation of occasion dewfall of especially carrying out low-temperature air conditioner is remarkable.
On the other hand, in the blowing mouth of record, porous plate is arranged on the central portion of blowing mouth in the patent documentation 2, so can prevent air the luring room air that blow out to a certain extent.But the air by porous plate flows towards the below, so existence is to occupant's such sticky feeling of directly drying.
Summary of the invention
In view of this, even the object of the present invention is to provide a kind of low-temperature air conditioner mode, also can be when the dewfall that prevents the blowing mouth surface take place, the blowing port for low temperature air conditioner that the air that blows out from blowing mouth is spread along ceiling towards horizontal direction.
In order to address the above problem, blowing port for low temperature air conditioner of the present invention, it is blowing mouth by the multilayer taper that a plurality of cones with square formation ring-type leave compartment of terrain concentric shape configuration, runner that Air Conditioning is formed each other from cone blows out, it is characterized in that, be configured in outermost outermost cone cone in addition, the longitudinal cross-section shape is identical respectively, simultaneously, the arranged spaced of the horizontal direction between the cone becomes to equate, in the inboard that is configured in the most inboard inner cone, be provided with the identical shaped flat pervasion component of peristome that forms with inner cone.
Here, " the longitudinal cross-section shape of cone is identical " is meant square and to form the vertical cross-section shape of each limit part of cone of ring-type identical.If make such shape, the cone beyond the outermost cone then can be utilized the long size members formation with cross sectional shape identical with the cross sectional shape longitudinally of the limit part of each cone.That is, with described long size members carry be cut into the length corresponding with the length of the limit part of each cone after, utilize member after means such as welding will the be cut off squarely ring-type that is bonded with each other, can make each cone.Thus, identical by the cross sectional shape on each limit of cone is made, can reduce the kind that becomes raw-material long size members when making cone.
In addition, " peristome of inner cone " is meant the peristome of the inner cone inboard when overlooking blowing mouth,, refers to the peristome of the upper end of inner cone that is.Each cone-shaped becomes makes air from blowing out towards outside diffuse underneath, when be configured in the face identical with the lower end of cone below pervasion component on, then forms the gap between the bottom of pervasion component and inner cone.
From the air that blowing mouth blows out, flow air and flat pervasion component collision in the cone runner of blowing mouth central portion and guide horizontal direction into blows out towards oblique below from the gap of pervasion component with inner cone.In addition, the air from the runner between each cone blows out also blows out towards oblique below.
In addition, the air that blows out from the gap with pervasion component in the flows inside of inner cone, its result becomes the state that this air covers inner cone, and this air can not lured room air the inboard of inner cone, can prevent that the dewfall of inner cone from taking place.
If will be configured to below the described pervasion component on the face identical with the lower end of inner cone cone in addition, and lower end that will inner cone is configured in the following high position than pervasion component, then flow air flows along the medial surface of inner cone in the gap of inner cone and pervasion component, thereby promotes this air to cover the effect of the inboard of inner cone.
Flow through the air of part the narrowest in the gap of pervasion component and inner cone, flow through the gap of throttling before, the air that flows through after the narrowest part is desired to enlarge once more.Passed through the gap after the narrowest part, disposed with vertical ground and clip by the inner face on the inner cone side of extending and form towards the side of the pervasion component of below extension towards oblique below.
The inner face of inner cone forms plane, forms abreast with each interpyramidal runner.
On the other hand, the runner that is formed by the inner face of pervasion component and inner cone is when pervasion component formation heavy wall, then the direction of passing through with respect to air-flow enlarges, so desire direction along the inner face airflow flowing of inner cone near the pervasion component side, that is, and near vertical.The heavy wall of pervasion component is thick more, and in addition, the runner of expansion is long more, and this effect just embodies by force more.
When in the direction of the air-flow of the flows inside of inner cone near vertical, then the difference of the direction (tiltedly below) of the air-flow of the runner that forms of the direction of this air and the gap of flowing through by the cone in the inner cone and the outside thereof becomes greatly.Therefore, the air of the flows inside of inner cone not with at the air interflow of flows outside, the bottom of the inner cone air that does not blow out that becomes covers, and on the blowing mouth surface dewfall takes place sometimes.
Here, when lower end that will inner cone is configured in than high position below the pervasion component, then disconnected halfway by the inner cone side of the inner face of inner cone and runner that pervasion component constitutes, so the air in the flows inside of inner cone is desired to enlarge towards horizontal direction, now near the airflow direction of vertical just near the direction that tilts.
On the other hand, flow through the air of the runner that the gap by the cone in the inner cone and the outside thereof forms, disconnected halfway because of the outside of the inner cone of the wall that constitutes the runner inboard, the direction of air-flow is then near vertical.
Under the double action of these 2 strands of air-flows, flow through the air in the gap of inner cone and pervasion component, with the air interflow of the formed runner in gap of the cone that flows through the inner cone and the outside thereof, the air that produces the gap of flowing through inner cone and pervasion component covers the effect of the bottom of inner cone.
When air blew out from blowing mouth, the air that room air is blown out from blowing mouth was lured, below pervasion component towards flows outside.For this reason, if insulation is set, make the pervasion component thermal insulation by this insulation on pervasion component, the following temperature of pervasion component can not reach the dew point of room air, and the following of pervasion component just dewfall can not take place yet like this.
When the thickness of described pervasion component forms below the 8mm, the thickness of wherein said insulation forms more than the 3.5mm, and then the following surface temperature of pervasion component can not reach the dew-point temperature of room air, can prevent the following generation dewfall of pervasion component reliably.In addition, thus, and can keep suitable gap between the inner cone, so can promote to cover the effect of inner cone at the air of Clearance Flow.
Here, with the thickness setting of pervasion component below 8mm, be because if surpassed 8mm, then the length of the side of pervasion component is elongated with the gap of inner cone with respect to pervasion component, the direction of air-flow in gap that flows through inner cone and pervasion component is near vertical, so become too big with the difference of the direction of the air of the formed runner in gap of the cone that flows through the inner cone and the outside thereof, 2 strands of air-flows of its result no longer collaborate, thereby the air that has lost the gap of flowing through inner cone and pervasion component covers the effect of the bottom of inner cone.
In addition, the scope of thickness setting more than 3.5mm with insulation, its reason is, when thickness less than 3.5mm, then the insulation effect of pervasion component weakens, in the occasion of carrying out low-temperature air conditioner, following temperature that might pervasion component reaches the dew-point temperature of room air, the following generation dewfall of pervasion component.
When the lower end with described inner cone is arranged on than more than the high 1mm and the position below on described pervasion component below the described pervasion component, then by flow air in the gap of inner cone and pervasion component, can prevent the inner face generation dewfall of inner cone reliably, simultaneously, can prevent the inner face generation dewfall of the cone adjacent with inner cone.
The lower end of inner cone is arranged on than more than the following high 1mm of described pervasion component and the position below on described pervasion component, be because, if below inner cone, do not have the occasion of 1mm, consider foozle and alignment error etc., with the roughly same plane of the following formation of pervasion component, thereby lose the cause of above-mentioned effect.
In addition, if the lower end of inner cone is in the top high position than pervasion component, then the direction of the air-flow that blows out from the gap of inner cone and pervasion component is near vertical, this air will be in the runner in the gap of inner cone and the cone adjacent with this inner cone below tiltedly flow air towards below lure, the air-flow that blows out from the inner face of the cone adjacent with inner cone is produced peel off, might produce the cause of dewfall.
The bottom of described cone with the chamber portion with cushion space is connected, described chamber portion is connected with neck, between the upstream-side-end of the end of downstream side of described neck and described cone, form restriction, then will be concentrated to the center from the air that neck flows into cushion space, this restriction envoy flow export produces air-swirl simultaneously, near the flow air of periphery of neck is spread towards the outside, air is collided with pervasion component reliably, simultaneously the periphery flow air is disperseed equably.
When on the described cone beyond the described outermost cone, being provided with: the longitudinal component that vertical is provided with; The oblique part that is connected with the lower side of this longitudinal component and air is induced towards oblique below; And be connected with the front end of this oblique part and when being darted at the transverse direction part of radial flow direction of air, then pass through longitudinal component, the air-stable ground that guides to interpyramidal runner is flowed into, by oblique part air is guided equably towards horizontal direction, pass through the lateral part, air-flow is caused the inboard of cone that is configured in the outside, can prevent peeling off of air-flow.
With the angle initialization of described oblique part scope at respect to the horizontal plane 45 ° ± 10 °, can prevent that then air-flow from peeling off from cone, reduce the pressure loss of blowing mouth simultaneously.
This occasion, with the angle initialization of oblique part scope at respect to the horizontal plane 45 ° ± 10 °, be because, when above 55 °, then air-flow is too towards the below, air-flow is peeled off between the ceiling surface in the inner face of outermost cone and its outside, not only air can't be guided towards horizontal direction, and the cause of dewfall might take place on the architrave of outermost cone.In addition, if with the angle initialization of oblique part less than 35 ° scope with respect to the horizontal plane, then interpyramidal runner narrows down, the pressure loss of blowing mouth is excessive, the cause that can't use as the blowing mouth of idle call.
In case the length of the described lateral part of the described cone beyond the described outermost cone is formed each cone configuration space 5~25%, then can not peel off from the air of the runner between the cone, can prevent minimizing from the blowing amount of blowing mouth.
This occasion, it with the length setting of lateral part 5~25% scope of the configuration space of each cone, be because, if less than 5%, the air that then guides to the lateral part reduces, and peels off sometimes from the air-flow of the inner face of outboard cone, and if surpass 25%, interpyramidal runner narrows down, and air-flow reduces, the cause that can't use as the blowing mouth of idle call.
