上記1)の輻射パネルによれば、パネル本体の全長にわたって形成された１対の溝形成用凸条からなる横断面優弧状ビスねじ嵌め溝を備えており、ビスねじ嵌め溝の両端がパネル本体の両端に開口しているので、輻射冷暖房ユニットに組み込む場合、垂直壁を有する１対の支持部材を互いに間隔をおいて配置し、両支持部材間に、複数の輻射パネルをその幅方向を支持部材の長さ方向に向けて並列状に配置し、支持部材の垂直壁を外側から貫通したビスを輻射パネルのビスねじ嵌め溝内にねじ嵌めることにより、輻射パネルの両端部を支持部材に固定することができる。したがって、この輻射冷暖房ユニットを有する輻射冷暖房装置を天井に組み込んだ場合、ビスが室内から見えることはなく、美観の低下を防止することができる。また、１対の溝形成用凸条が補強リブの働きをするので、上下方向の剛性がアップし、輻射冷暖房ユニットに組み込んだ場合の輻射パネルの下方への撓みを抑制することができる。 According to the radiation panel of the above 1), it has a cross-section arc-shaped screw screw fitting groove formed of a pair of groove forming ridges formed over the entire length of the panel body, and both ends of the screw screw fitting groove are at the panel body. When installing in a radiant cooling and heating unit, a pair of support members having vertical walls are arranged at intervals from each other, and a plurality of radiant panels are supported in the width direction between the two support members. Fixing both ends of the radiant panel to the support member by arranging them in parallel in the length direction of the member and screwing the screw that penetrates the vertical wall of the support member from the outside into the screw screw fitting groove of the radiant panel can do. Therefore, when the radiant cooling / heating device having this radiant cooling / heating unit is incorporated in the ceiling, the screws are not seen from the room, and the appearance can be prevented from deteriorating. In addition, since the pair of groove-forming ridges function as reinforcing ribs, the rigidity in the vertical direction is increased, and the downward bending of the radiant panel when incorporated in the radiant cooling and heating unit can be suppressed.
上記1)の輻射パネルを輻射冷暖房装置に用いた場合、パネル本体が、水平面に対して傾斜した傾斜部分を有しているので、天井投影面積あたりのパネル本体の面積が増大し、その結果冷暖房効率が優れたものになる。また、上記4)の輻射パネルを輻射冷房装置に用いた場合、冷房を行う際には、パネル本体の傾斜部分の上下両面に沿って空気の流れが発生し、その結果冷輻射に加えて自然対流による冷房効果が得られる。しかも、傾斜部分の上下両面に沿う空気の流れの流速は、比較的大きくなり、空気と傾斜部分との間の熱伝達率が向上する。さらに、上記1)の輻射パネルによれば、傾斜部分の下端から保持部形成用凸条の上端までの高さが比較的大きくなり、その結果上下方向の剛性が向上し、輻射パネルの下方への撓みを抑制することができる。 When the radiation panel of 1) above is used in a radiant cooling and heating device, the panel body has an inclined portion that is inclined with respect to the horizontal plane, so that the area of the panel body per ceiling projection area increases, resulting in cooling and heating. Efficiency will be excellent. In addition, when the radiant panel of 4) is used in a radiant cooling device, when cooling is performed, air flows along the upper and lower surfaces of the inclined portion of the panel body. Cooling effect by convection is obtained. Moreover, the flow velocity of the air flow along the upper and lower surfaces of the inclined portion becomes relatively large, and the heat transfer coefficient between the air and the inclined portion is improved. Further, according to the radiation panel of 1) above, the height from the lower end of the inclined portion to the upper end of the protrusion for forming the holding portion is relatively large, and as a result, the vertical rigidity is improved, and the downward direction of the radiation panel. Can be suppressed .
上記2)および3)の輻射パネルを輻射冷暖房ユニットに組み込んだ場合、蛇行状流体流通管の直管部を輻射パネルの管保持部内に嵌め入れて固定すると、特許文献１記載の輻射冷暖房ユニットの場合のように、蛇行状流体流通管の屈曲管部を上方に曲げることなく、屈曲管部を両支持部材よりも内側に位置させることができる。したがって、作業性が向上する。また、屈曲管部を両支持部材よりも内側に位置させることができるので、複数の輻射冷暖房ユニットを輻射パネルの長さ方向に並べた場合、隣り合う輻射冷暖房ユニットどうしを近接して配置することができる。 When the radiation panels of the above 2) and 3) are incorporated in a radiation cooling / heating unit, the straight pipe portion of the meandering fluid circulation pipe is fixed by being fitted into the tube holding portion of the radiation panel. As in the case, the bent pipe part can be positioned on the inner side of the two support members without bending the bent pipe part of the meandering fluid flow pipe upward. Therefore, workability is improved. In addition, since the bent pipe portion can be positioned inside both support members, when a plurality of radiant cooling and heating units are arranged in the length direction of the radiant panel, adjacent radiant cooling and heating units are arranged close to each other. Can do .
上記4)の輻射パネルによれば、立ち上がり壁の働きにより上下方向の剛性が向上し、輻射パネルの下方への撓みを抑制することができる。また、上記5)の輻射パネルを有する輻射冷暖房ユニットを備えた輻射冷暖房装置を天井に組み込んだ場合、冷房時、特に冷房運転開始時に媒体流通部に冷却媒体を流した際に媒体流通部の外表面に結露水が発生したとしても、発生した結露水は立ち上がり壁に受けられ、その結果結露水が室内へ落下することが防止される。さらに、天井裏に溜まった埃も立ち上がり壁に受けられ、その結果埃が室内へ落下することが防止される。しかも、立ち上がり壁が隣り合う輻射パネル間の間隙の目隠しとなり、室内側から隣り合う輻射パネル間の隙間を通して天井裏が見えにくくなるので、美観が向上する。 According to the radiation panel of 4), the vertical rigidity is improved by the action of the rising wall, and the downward bending of the radiation panel can be suppressed. In addition, when the radiant cooling / heating device including the radiant cooling / heating unit having the radiating panel of 5) above is incorporated in the ceiling, when the cooling medium is allowed to flow through the medium circulation unit at the time of cooling, particularly at the start of the cooling operation, the outside of the medium circulation unit. Even if condensed water is generated on the surface, the generated condensed water is received by the rising wall, and as a result, the condensed water is prevented from falling into the room. Furthermore, dust accumulated on the back of the ceiling is also received by the rising wall, and as a result, the dust is prevented from falling into the room. In addition, the rising wall serves as a blindfold between the adjacent radiant panels, and the back of the ceiling becomes difficult to see through the gap between the adjacent radiant panels from the indoor side, so that the aesthetics are improved.
上記5)の輻射パネルによれば、断面係数が上記4)の輻射パネルよりも大きくなるので、上下方向の剛性が一層向上し、輻射パネルの下方への撓みをより効果的に抑制することができる。また、上記5)の輻射パネルを輻射冷房装置に用いた場合、冷房を行う際には、パネル本体の傾斜部分の上下両面に沿って空気の流れが発生するが、垂下壁は傾斜部分の上面に沿う空気の流れを妨げることはないので、自然対流による冷房効果の低下が防止される。しかも、垂下壁が隣り合う輻射パネル間の間隙の目隠しとなり、室内側から隣り合う輻射パネル間の隙間を通して天井裏が見えにくくなるので、美観が向上する。 According to the radiation panel of 5) above, since the section modulus is larger than that of the radiation panel of 4) above, the vertical rigidity is further improved, and the downward deflection of the radiation panel can be more effectively suppressed. it can. In addition, when the radiation panel of 5) is used for a radiation cooling device, when cooling is performed, an air flow occurs along both the upper and lower surfaces of the inclined portion of the panel body, but the hanging wall is the upper surface of the inclined portion. Therefore, the cooling effect due to natural convection is prevented from being deteriorated. In addition, the hanging wall serves as a blindfold between the adjacent radiation panels, and the back of the ceiling becomes difficult to see through the gap between the adjacent radiation panels from the indoor side, so that the aesthetics are improved.
上記6)の輻射パネルによれば、ビスねじ嵌め溝が、パネル本体における各傾斜部分の傾斜下端部に形成されているので、上下方向の剛性が向上し、輻射パネルの下方への撓みを抑制することができる。 According to the radiation panel of 6) above, since the screw screw fitting groove is formed at the inclined lower end of each inclined portion in the panel body, the vertical rigidity is improved and the downward bending of the radiation panel is suppressed. can do.
上記7)の輻射冷暖房ユニットを有する輻射冷暖房装置を天井に組み込んだ場合、ビスが室内から見えることはなく、美観の低下を防止することができる。また、１対の溝形成用凸条が補強リブの働きをするので、上下方向の剛性がアップし、輻射パネルの下方への撓みを抑制することができる。 When the radiant cooling / heating device having the radiant cooling / heating unit of the above 7) is incorporated in the ceiling, the screws are not visible from the room, and the appearance can be prevented from deteriorating. In addition, since the pair of groove forming ridges function as reinforcing ribs, the rigidity in the vertical direction is increased, and the downward bending of the radiation panel can be suppressed.
上記8)の輻射冷暖房ユニットを有する輻射冷暖房装置を天井に組み込んだ場合、ビスが室内から見えることはなく、美観の低下を防止することができる。また、１対の溝形成用凸条が補強リブの働きをするので、上下方向の剛性がアップし、輻射パネルの下方への撓みを抑制することができる。さらに、上記8)の輻射冷暖房ユニットによれば、蛇行状流体流通管の直管部を輻射パネルの管保持部内に嵌め入れて固定すると、特許文献１記載の輻射冷暖房ユニットの場合のように、蛇行状流体流通管の屈曲管部を上方に曲げることなく、屈曲管部を両支持部材よりも内側に位置させることができる。したがって、作業性が向上する。また、屈曲管部を両支持部材よりも内側に位置させることができるので、複数の輻射冷暖房ユニットを輻射パネルの長さ方向に並べた場合、隣り合う輻射冷暖房ユニットどうしを近接して配置することができる。
When the radiant cooling and heating apparatus having the radiant cooling and heating unit of 8) is incorporated in the ceiling, the screws are not visible from the room, and the appearance can be prevented from being deteriorated. In addition, since the pair of groove forming ridges function as reinforcing ribs, the rigidity in the vertical direction is increased, and the downward bending of the radiation panel can be suppressed. Furthermore, according to the radiation cooling and heating unit of the above 8) , when the straight pipe portion of the meandering fluid circulation pipe is fitted and fixed in the tube holding portion of the radiation panel, as in the case of the radiation cooling and heating unit described in
上記9)の輻射冷暖房ユニットによれば、特許文献１記載の輻射冷暖房ユニットの場合のように、蛇行状流体流通管の屈曲管部を上方に曲げることなく、屈曲管部を両支持部材よりも内側に位置させることができる。したがって、作業性が向上する。しかも、特許文献１記載の輻射冷暖房ユニットの場合、蛇行状流体流通管の直管部の管保持部内への圧入と屈曲管部の上方への曲げを同時に行った場合、蛇行状流体流通管が位置ずれすることがあるが、このような位置ずれを防止することができる。また、屈曲管部を両支持部材よりも内側に位置させることができるので、複数の輻射冷暖房ユニットを輻射パネルの長さ方向に並べた場合、隣り合う輻射冷暖房ユニットどうしを近接して配置することができる。さらに、輻射冷暖房ユニットの保管時や輸送時には、複数の輻射冷暖房ユニットを段積みすることが可能となり、保管や輸送のスペースを小さくすることができる。
According to the radiant cooling and heating unit of the above 9) , as in the case of the radiant cooling and heating unit described in
上記13)の輻射冷暖房ユニットを備えた輻射冷暖房装置を天井に組み込んだ場合、目隠し部材の働きにより、室内側から隣り合う輻射パネル間の隙間を通して天井裏が見えにくくなるので、美観が向上する。 When the radiant cooling / heating device including the radiant cooling / heating unit of 13) above is incorporated in the ceiling, the back of the ceiling becomes difficult to see through the gap between the adjacent radiant panels from the indoor side by the action of the blindfold member, so that the appearance is improved.
上記14)の輻射冷暖房ユニットを備えた輻射冷暖房装置を天井に組み込んだ場合、冷房を行う際には、パネル本体の傾斜部分の上下両面に沿って空気の流れが発生し、その結果冷輻射に加えて自然対流による冷房効果が得られるが、傾斜部分の上面に沿って流れる空気は、隣り合う脚部分間の間隙を通って下方に流れる。したがって、傾斜部分の上面に沿う空気の流れを妨げることはないので、自然対流による冷房効果の低下が防止される。 When the radiant cooling / heating device equipped with the radiant cooling / heating unit of 14) above is installed in the ceiling, air flow is generated along both the upper and lower surfaces of the inclined part of the panel body, resulting in cooling radiation. In addition, although a cooling effect by natural convection is obtained, air flowing along the upper surface of the inclined portion flows downward through a gap between adjacent leg portions. Accordingly, since the air flow along the upper surface of the inclined portion is not hindered, the cooling effect due to natural convection is prevented from being lowered.
上記15)の輻射冷暖房ユニットによれば、輻射パネルの長さが長くなった場合にも、補強吊り部材の働きにより輻射パネルの下方への撓みを防止することができる。 According to the radiation cooling / heating unit of the above 15) , even when the length of the radiation panel is increased, the downward bending of the radiation panel can be prevented by the function of the reinforcing suspension member.

The other part of the tube wall is plastically deformed so as to bulge outward (see FIG. 2). Since the straight pipe portion (4a) is formed by plastic deformation as described above, both the holding portion forming ridges (13) are elastically deformed outward in the left-right direction, and in this state The straight pipe part (4a) is fixed in the pipe holding part (14). The U-shaped bent pipe part (4b) of the meandering fluid circulation pipe (4) is located outside the pipe holding part (14) and inside the front-rear direction than the support member (2).

Further, at least one of the inner and outer peripheral surfaces of the metal tube may be covered with a resin layer made of a synthetic resin having excellent corrosion resistance, such as polyethylene.
各輻射パネル(3)の長さ方向の中間部には、蛇行状流体流通管(4)の直管部(4a)の上から補強吊り部材(15)が取り付けられている。補強吊り部材(15)は、水平板状の基部(16)と、基部(16)の左右両側縁に一体に形成されかつ左右方向外方に向かって下方に傾斜した脚部(17)を有しており、脚部(17)の下端部に、輻射パネル(3)のビスねじ嵌め溝(8)内に嵌め入れられる嵌入部(18)が一体に形成されている。嵌入部(18)は軸線が前後方向を向いた円柱状であって、その直径はビスねじ嵌め溝(8)の両溝形成用凸条(9)の先端間の間隔よりも大きくなっており、両溝形成用凸条(9)の先端間の間隙を通してビスねじ嵌め溝(8)内に圧入されている。補強吊り部材(15)の基部(16)には、左右方向に伸びるＴ形部(19)が上方突出状に設けられている。補強吊り部材(15)は、基部(16)、脚部(17)および嵌入部(18)を、たとえばアルミニウムから一体に押出成形するとともに、これとは別個にＴ形部(19)を、たとえばアルミニウムから一体に押出成形し、適当な方法、たとえば溶接により基部(16)にＴ形部(19)を固着することにより形成されている。 A reinforcing suspension member (15) is attached to an intermediate portion in the length direction of each radiation panel (3) from above the straight pipe portion (4a) of the meandering fluid circulation pipe (4).

The reinforcing suspension member (15) is formed by integrally extruding the base portion (16), the leg portion (17), and the fitting portion (18) from, for example, aluminum, and separately forming the T-shaped portion (19), for example, It is formed by extruding integrally from aluminum and fixing the T-shaped portion (19) to the base portion (16) by an appropriate method, for example, welding.
輻射冷暖房ユニット(1)は、図５および図６に示すようにして、冷暖房すべき室内の広さに応じた適当数がシステム天井に組み込まれ、輻射冷暖房装置(20)として用いられる。 As shown in FIGS. 5 and 6, an appropriate number of radiant cooling / heating units (1) corresponding to the size of the room to be cooled / heated is incorporated in the system ceiling and used as the radiant cooling / heating device (20).
すなわち、システム天井においては、天井スラブ(21)に垂下状に固定された吊りボルト(22)にハンガー(23)が取り付けられ、前後方向に間隔をおいて複数配置されたＴバー(24)がハンガー(23)に吊持されている。そして、各輻射冷暖房ユニット(1)の支持部材(2)が、Ｔバー(24)の水平フランジ部(24a)上に載せられることにより、輻射冷暖房ユニット(1)がシステム天井に組み込まれている。また、補強吊り部材(15)のＴ形部(19)の頭部(19a)が、ハンガー(23)の下端に形成された内部拡大溝(23a)内に嵌め入れられている。なお、輻射パネル(3)の前後方向の長さが短く、パネル本体(7)の傾斜部分(12)、保持部形成用凸条(13)および溝形成用凸条(9)による剛性アップによって、輻射パネル(3)が下方に撓むことのないような長さであれば、補強吊り部材(15)は必ずしも必要としない。 That is, on the system ceiling, hangers (23) are attached to the suspension bolts (22) fixed in a suspended manner to the ceiling slab (21), and a plurality of T bars (24) arranged at intervals in the front-rear direction. It is suspended on a hanger (23). The support member (2) of each radiant cooling / heating unit (1) is placed on the horizontal flange portion (24a) of the T-bar (24), so that the radiant cooling / heating unit (1) is incorporated in the system ceiling. . Further, the head portion (19a) of the T-shaped portion (19) of the reinforcing suspension member (15) is fitted into an internal enlarged groove (23a) formed at the lower end of the hanger (23). The length of the radiant panel (3) in the front-rear direction is short, and the panel body (7) has a slanted portion (12), holding portion forming ridges (13), and groove forming ridges (9). If the length is such that the radiation panel (3) does not bend downward, the reinforcing suspension member (15) is not necessarily required.
上記輻射冷暖房装置(20)を用いて室内を冷暖房するには、蛇行状流体流通管(4)に低温の冷却媒体または高温の加熱媒体を流す。すると、冷輻射または熱輻射により室内が冷暖房される。特に、冷房する場合には、図７に示すように、両傾斜部分(12)の上下両面に沿って空気の流れが発生し、その結果冷輻射に加えて自然対流による冷却効果が得られ、冷房効率が向上する。すなわち、パネル本体(7)の２つの傾斜部分(12)の上面に沿って流れた空気は隣り合う輻射パネル(3)のパネル本体(7)間の隙間を通って下方へ流れ、この流れに２つの傾斜部分(12)の下面に沿って流れた空気が合流することになり、自然対流による冷却効果が優れたものになる。しかも、傾斜部分(12)の上下両面に沿う空気の流れの流速は、水平の場合に比べて大きくなり、空気と傾斜部分(12)との間の熱伝達率が向上する。 In order to cool and heat the room using the radiant cooling and heating device (20), a low-temperature cooling medium or a high-temperature heating medium is passed through the meandering fluid circulation pipe (4). Then, the room is air-conditioned by cold radiation or heat radiation. In particular, in the case of cooling, as shown in FIG. 7, air flows are generated along the upper and lower surfaces of both inclined portions (12). As a result, in addition to cooling radiation, a cooling effect by natural convection is obtained, Cooling efficiency is improved. That is, the air flowing along the upper surfaces of the two inclined portions (12) of the panel body (7) flows downward through the gap between the panel bodies (7) of the adjacent radiation panels (3). The air flowing along the lower surfaces of the two inclined portions (12) will merge, and the cooling effect by natural convection will be excellent. Moreover, the flow velocity of the air flow along the upper and lower surfaces of the inclined portion (12) is larger than that in the horizontal case, and the heat transfer coefficient between the air and the inclined portion (12) is improved.
図８は、この発明による輻射パネルの第２の実施形態を示す。 FIG. 8 shows a second embodiment of the radiation panel according to the present invention.
図８において、輻射パネル(30)のパネル本体(7)の水平部分(11)上面に形成された両保持部形成用凸条(13)の両端部が、それぞれ所定長さにわたって切除されており、両保持部形成用凸条(13)における残存した部分により、横断面略Ｕ字状の管保持部(14)が形成されている。その他の構成は第１の実施形態の輻射パネル(3)と同じである。この輻射パネル(30)は、上述した第１の実施形態の場合と同様にして、支持部材(2)とともに輻射冷暖房ユニット(1)を構成する。 In FIG. 8, both end portions of both holding portion forming ridges (13) formed on the upper surface of the horizontal portion (11) of the panel body (7) of the radiation panel (30) are cut out over a predetermined length. The remaining portions of both the holding portion forming ridges (13) form a tube holding portion (14) having a substantially U-shaped cross section. Other configurations are the same as those of the radiation panel (3) of the first embodiment. This radiant panel (30) constitutes a radiant cooling and heating unit (1) together with the support member (2) in the same manner as in the first embodiment described above.
図９は、この発明による輻射パネルの第３の実施形態を示す。 FIG. 9 shows a third embodiment of the radiation panel according to the present invention.
図９において、輻射パネル(31)のパネル本体(32)は、全体に平坦な板状となっている。そして、パネル本体(32)上面の左右両側部分に、その全長にわたって一体に形成された１対の溝形成用凸条(9)からなる横断面優弧状ビスねじ嵌め溝(8)が形成され、左右方向の中央部に、１対の保持部形成用凸条(13)からなる管保持部(14)が形成されている。その他の構成は第１の実施形態の輻射パネル(3)と同じである。管保持部(14)は、図４に示すように、両保持部形成用凸条(13)の両端部を、それぞれ所定長さにわたって外側に折り曲げられて平坦となるように潰すこと、または図８に示すように、両保持部形成用凸条(13)の両端部を、それぞれ所定長さにわたって切除されることにより形成されている。 In FIG. 9, the panel body (32) of the radiation panel (31) has a flat plate shape as a whole. And, on the left and right side portions of the upper surface of the panel body (32), a cross-sectionally superior arc screw screw fitting groove (8) comprising a pair of groove forming ridges (9) integrally formed over the entire length is formed, A tube holding part (14) composed of a pair of holding part forming ridges (13) is formed at the center in the left-right direction. Other configurations are the same as those of the radiation panel (3) of the first embodiment. As shown in FIG. 4, the tube holding part (14) is crushed so that both end parts of both holding part forming ridges (13) are bent outward over a predetermined length so as to be flat, or As shown in FIG. 8, both end portions of both holding portion forming ridges (13) are formed by being cut out over a predetermined length.
この輻射パネル(3)は、上述した第１の実施形態の場合と同様にして、支持部材(2)とともに輻射冷暖房ユニットを構成する。但し、パネル本体(32)が水平状に配置される場合と、傾斜状に配置される場合とがある。後者の場合、輻射冷暖房ユニットを備えた輻射冷暖房装置を用いて室内を冷房するには、パネル本体(32)の上下両面に沿って空気の流れが発生し、その結果冷輻射に加えて自然対流による冷却効果が得られ、冷房効率が向上する。すなわち、パネル本体(32)の上面に沿って流れた空気は隣り合う輻射パネル(31)のパネル本体(32)間の隙間を通って下方へ流れ、この流れにパネル本体(32)の下面に沿って流れた空気が合流することになり、自然対流による冷却効果が優れたものになる。しかも、パネル本体(32)の上下両面に沿う空気の流れの流速は、水平の場合に比べて大きくなり、空気と傾斜部分(12)との間の熱伝達率が向上する。 This radiant panel (3) constitutes a radiant cooling and heating unit together with the support member (2) in the same manner as in the first embodiment described above. However, there are a case where the panel body (32) is arranged horizontally and a case where the panel body (32) is arranged inclined. In the latter case, in order to cool a room using a radiant cooling / heating device equipped with a radiant cooling / heating unit, air flows along the upper and lower surfaces of the panel body (32), resulting in natural convection in addition to cooling radiation. The cooling effect is obtained, and the cooling efficiency is improved. That is, the air that flows along the upper surface of the panel body (32) flows downward through the gap between the panel bodies (32) of the adjacent radiation panels (31), and this flow is applied to the lower surface of the panel body (32). The air that has flowed along will join, and the cooling effect by natural convection will be excellent. In addition, the flow velocity of the air flow along the upper and lower surfaces of the panel body (32) is larger than that in the horizontal case, and the heat transfer coefficient between the air and the inclined portion (12) is improved.
図１０は、この発明による輻射パネルの第４の実施形態を示す。 FIG. 10 shows a fourth embodiment of the radiation panel according to the present invention.
図１０において、輻射パネル(35)のパネル本体(7)における各傾斜部分(12)の傾斜下端部に、垂直上方に突出した立ち上がり壁(36)が全長にわたって一体に形成されている。その他の構成は第１の実施形態の輻射パネル(3)と同じである。この輻射パネル(35)は、上述した第１の実施形態の場合と同様にして、支持部材(2)とともに輻射冷暖房ユニット(1)を構成する。 In FIG. 10, a rising wall (36) protruding vertically upward is integrally formed over the entire length at the inclined lower end portion of each inclined portion (12) in the panel body (7) of the radiation panel (35). Other configurations are the same as those of the radiation panel (3) of the first embodiment. This radiant panel (35) constitutes a radiant cooling / heating unit (1) together with the support member (2) in the same manner as in the first embodiment described above.
図１０に示す輻射パネル(35)を有する輻射冷暖房ユニット(1)を備えた輻射冷暖房装置(20)を用いて室内を冷房する場合には、特に冷房運転開始時に冷却媒体を流した流体流通管(4)の外表面に結露水が発生することがある。この結露水は、輻射パネル(35)のパネル本体(7)の傾斜部分(12)に沿って下方に流れるが、この結露水は立ち上がり壁(36)に受けられるので、結露水が室内へ落下することが防止される。さらに、天井裏に溜まった埃が輻射パネル(35)のパネル本体(7)に落下したとしても、この埃も立ち上がり壁(36)に受けられ、その結果埃が室内へ落下することが防止される。さらに、輻射パネル(35)を有する輻射冷暖房ユニット(1)を備えた輻射冷暖房装置(20)をシステム天井に組み込んだ場合、立ち上がり壁(36)が隣り合う輻射パネル(35)間の間隙の目隠しとなり、室内側から隣り合う輻射パネル(35)間の隙間を通して天井裏が見えにくくなるので、美観が向上する。 When the room is cooled using the radiant cooling / heating device (20) including the radiant cooling / heating unit (1) having the radiant panel (35) shown in FIG. 10, the fluid flow pipe in which the cooling medium is flowed particularly at the start of the cooling operation. Condensed water may form on the outer surface of (4). This condensed water flows downward along the inclined part (12) of the panel body (7) of the radiation panel (35), but this condensed water is received by the rising wall (36), so the condensed water falls into the room. Is prevented. Furthermore, even if dust collected on the back of the ceiling falls on the panel body (7) of the radiation panel (35), this dust is also received by the rising wall (36), and as a result, it is prevented from falling into the room. The Furthermore, when a radiant cooling / heating device (20) having a radiant cooling / heating unit (1) having a radiant panel (35) is incorporated in the system ceiling, the rising wall (36) blinds the gap between adjacent radiant panels (35). Thus, it is difficult to see the back of the ceiling through the gap between the adjacent radiation panels (35) from the indoor side, so the aesthetics are improved.
図１１は、この発明による輻射パネルの第５の実施形態を示す。 FIG. 11 shows a fifth embodiment of a radiation panel according to the present invention.
図１１において、輻射パネル(40)のパネル本体(7)における各傾斜部分(12)の傾斜下端部に、垂直下方に突出した垂下壁(41)が全長にわたって一体に形成されている。その他の構成は第１の実施形態の輻射パネル(3)と同じである。この輻射パネル(40)は、上述した第１の実施形態の場合と同様にして、支持部材(2)とともに輻射冷暖房ユニット(1)を構成する。 In FIG. 11, a drooping wall (41) projecting vertically downward is integrally formed at the lower end of each inclined portion (12) of the panel body (7) of the radiation panel (40). Other configurations are the same as those of the radiation panel (3) of the first embodiment. This radiant panel (40) constitutes a radiant cooling / heating unit (1) together with the support member (2) in the same manner as in the first embodiment described above.
図１１に示す輻射パネル(40)を有する輻射冷暖房ユニット(1)を備えた輻射冷暖房装置(20)をシステム天井に組み込んだ場合、垂下壁(41)が隣り合う輻射パネル(40)間の間隙の目隠しとなり、室内側から隣り合う輻射パネル(40)間の隙間を通して天井裏が見えにくくなるので、美観が向上する。 When the radiant cooling / heating device (20) having the radiant cooling / heating unit (1) having the radiant panel (40) shown in FIG. 11 is incorporated in the system ceiling, the hanging wall (41) is a gap between adjacent radiant panels (40). Since the ceiling is difficult to see through the gap between adjacent radiant panels (40) from the indoor side, the aesthetics are improved.
また、この輻射冷暖房装置(20)を用いて室内を冷房する場合には、図７に示すように、両傾斜部分(12)の上下両面に沿って空気の流れが発生するが、両傾斜部分(12)の上面に沿う空気の流れが、垂下壁(41)により妨げられることはないので、上述した自然対流による冷却効果が低下するおそれはない。 Further, when the room is cooled by using this radiant cooling / heating device (20), as shown in FIG. 7, an air flow is generated along both upper and lower surfaces of both inclined portions (12). Since the air flow along the upper surface of (12) is not hindered by the drooping wall (41), there is no possibility that the cooling effect by the natural convection described above will be lowered.
図１２は、この発明による輻射パネルの第６の実施形態を示す。 FIG. 12 shows a sixth embodiment of a radiation panel according to the present invention.
図１２において、輻射パネル(45)のビスねじ嵌め溝(8)は、パネル本体(7)における各傾斜部分(12)の傾斜下端部に形成されている。その他の構成は第１の実施形態の輻射パネル(3)と同じである。この輻射パネル(45)は、上述した第１の実施形態の場合と同様にして、支持部材(2)とともに輻射冷暖房ユニット(1)を構成する。 In FIG. 12, the screw screw fitting groove (8) of the radiation panel (45) is formed at the inclined lower end of each inclined portion (12) in the panel body (7). Other configurations are the same as those of the radiation panel (3) of the first embodiment. This radiant panel (45) constitutes a radiant cooling and heating unit (1) together with the support member (2) in the same manner as in the first embodiment described above.
各輻射パネル(45)の長さ方向の中間部には、蛇行状流体流通管(4)の直管部(4a)の上から補強吊り部材(15A)が取り付けられている。この補強吊り部材(15A)は、水平板状基部(16A)の幅および脚部(17A)の幅が、水平板状基部(16)の幅および脚部(17)の幅よりも大きいことを除いては、図２に示す補強吊り部材(15)と同様な構成である。 A reinforcing suspension member (15A) is attached to an intermediate portion in the length direction of each radiation panel (45) from above the straight pipe portion (4a) of the meandering fluid circulation pipe (4). The reinforcing suspension member (15A) is such that the width of the horizontal plate base (16A) and the width of the leg (17A) are larger than the width of the horizontal plate base (16) and the width of the leg (17). Except for this, the configuration is the same as that of the reinforcing suspension member (15) shown in FIG.
また、パネル本体(7)の傾斜部分(12)、保持部形成用凸条(13)および溝形成用凸条(9)による剛性アップによって、輻射パネル(45)が下方に撓むおそれがなければ、補強吊り部材(15A)は必ずしも必要としない。 In addition, the radiation panel (45) may not bend downward due to increased rigidity due to the slanted portion (12) of the panel body (7), the protrusions for holding portion formation (13), and the protrusions for groove formation (9). In this case, the reinforcing suspension member (15A) is not necessarily required.
補強吊り部材(15A)を用いる必要がない場合、図１３に示すように、輻射冷暖房ユニット(1)における隣り合う輻射パネル(45)間に、輻射パネル(45)の全長にわたる目隠し部材(46)が配置されることがある。目隠し部材(46)は、図１４に示すように、輻射パネル(45)の長さ方向に伸びかつ隣り合う輻射パネル(45)間の隙間を隠す水平帯板状目隠し部分(47)と、目隠し部分(47)の両側縁部に、それぞれその長さ方向に間隔をおいて断続的に形成された複数の脚部分(48)とを備えており、各脚部分(48)の下端部に、隣り合う２つの輻射パネル(46)における互いに近接したビスねじ嵌め溝(8)内に嵌め入れられる嵌入部(49)が形成されている。嵌入部(49)は軸線が前後方向を向いた円柱状であって、その直径はビスねじ嵌め溝(8)の両溝形成用凸条(9)の先端間の間隔よりも大きくなっており、両溝形成用凸条(9)の先端間の間隙を通してビスねじ嵌め溝(8)内に圧入されている。 When it is not necessary to use the reinforcing suspension member (15A), as shown in FIG. 13, between the adjacent radiant panels (45) in the radiant cooling and heating unit (1), a blindfold member (46) covering the entire length of the radiant panel (45). May be placed. As shown in FIG. 14, the blindfold member (46) extends in the length direction of the radiation panel (45) and hides the gap between the adjacent radiation panels (45), and the blind strip (47) and the blindfold. A plurality of leg portions (48) formed intermittently at intervals in the length direction on both side edges of the portion (47), and at the lower end of each leg portion (48), A fitting portion (49) that is fitted into the screw screw fitting groove (8) adjacent to each other in the two adjacent radiation panels (46) is formed. The insertion part (49) has a cylindrical shape whose axis is directed in the front-rear direction, and its diameter is larger than the distance between the tips of the two groove forming ridges (9) of the screw thread fitting groove (8). The screw thread fitting groove (8) is press-fitted through the gap between the tips of the groove forming convex strips (9).
隣り合う輻射パネル(45)間に目隠し部材(46)が配置された輻射冷暖房ユニット(1)を備えた輻射冷暖房装置(20)をシステム天井に組み込んだ場合、目隠し部材(46)の目隠し部(47)が隣り合う輻射パネル(45)間の間隙の目隠しとなり、室内側から隣り合う輻射パネル(45)間の隙間を通して天井裏が見えにくくなるので、美観が向上する。 When a radiant cooling / heating device (20) having a radiant cooling / heating unit (1) in which a blindfold member (46) is arranged between adjacent radiant panels (45) is incorporated in the system ceiling, the blindfold of the blindfold member (46) ( 47) serves as a blindfold between the adjacent radiant panels (45), and it is difficult to see the back of the ceiling through the gap between the adjacent radiant panels (45) from the indoor side.
また、目隠し部材(46)が配置された輻射冷暖房ユニット(1)を備えた輻射冷暖房装置(20)を用いて室内を冷房する場合には、図７に示すように、両傾斜部分(12)の上下両面に沿って空気の流れが発生するが、両傾斜部分(12)の上面に沿って流れる空気は、目隠し部材(46)の隣り合う脚部分(48)間の間隙を通過し、さらに隣り合う輻射パネル(45)のパネル本体(7)間の隙間を通って下方へ流れる。したがって、上述した自然対流による冷却効果が低下するおそれはない。 Further, when the room is cooled using the radiant cooling / heating device (20) including the radiant cooling / heating unit (1) in which the blindfold member (46) is disposed, as shown in FIG. 7, both inclined portions (12) The air flows along both the upper and lower surfaces of the gas, but the air flowing along the upper surfaces of both inclined portions (12) passes through the gap between the adjacent leg portions (48) of the blindfold member (46), and It flows downward through the gap between the panel bodies (7) of the adjacent radiation panels (45). Therefore, there is no possibility that the cooling effect due to the natural convection described above is lowered.
