Embodiments for Carrying Out the Invention

[0024] Hereinafter, each embodiment of the present invention will be described with reference to the drawings and the like. However, the present invention can be implemented in various modes without departing from the gist thereof, and is not to be construed as being limited to the description content of the embodiments exemplified below.

[0025] The drawings may schematically represent the width, thickness, shape, etc. of each part compared with the actual aspect for the sake of clearer explanation, but this is merely an example and does not limit the interpretation of the present invention. In this specification and each figure, elements having the same functions as those described with respect to the previously shown figures may be denoted by the same reference numerals, and redundant explanations may be omitted. When representing a part of an element with a reference numeral, a small letter of the alphabet is appended to the reference numeral.

[0026] <First Embodiment> In this embodiment, the radiant air conditioning system 100 according to one embodiment of the present invention and its construction method will be described.

[0027] 1. Configuration of the radiant air conditioning system FIGS. 1A and 1B show schematic perspective views of the radiant air conditioning system 100. FIGS. 1A and 1B are perspective views of the radiant air conditioning system 100 seen from above and below, respectively. As shown in these figures, the radiant air conditioning system 100 includes an air conditioner 110, a spacer 120, a mounting fixture 140, a heat insulating panel 160, and a heat radiation panel 180. The radiant air conditioning system 100 utilizes heat radiation as at least part of the mechanism for regulating the indoor temperature. Specifically, during heating, the air heated by the air conditioner 110 is introduced through the spacer 120 into the space between the heat insulating panel 160 and the heat radiation panel 180, and then released into the room. At this time, since the heat radiation panel 180 is heated by the heated air, not only the convection caused by the released air but also the heat radiation from the heated heat radiation panel 180 contributes to the rise in the indoor temperature. Similarly, during cooling, the air cooled by the air conditioner 110 is introduced through the spacer 120 between the heat insulating panel 160 and the heat radiation panel 180, and the heat radiation panel 180 is cooled. The cooled air is then released into the room, but since not only the convection caused by this air flow but also the heat (i.e., far-infrared rays) radiated from the indoor air, ceiling, walls, furniture, people, etc. is absorbed by the heat radiation panel 180, the room is cooled.

[0028] As can be understood from FIG. 1B, the radiant air conditioning system 100 is installed on the ceiling 200 and the wall 202. Specifically, the air conditioner 110 is fixed to the wall 202, and a spacer 120 is provided between the air conditioner 110 and the ceiling 200. On the other hand, the mounting fixture 140 is fixed to the ceiling 200 on the front side of the air conditioner 110 and is connected to the spacer 120. The heat insulation panel 160 is fixed to the mounting fixture 140 and is connected to the spacer 120. The heat radiation panel 180 is attached to the mounting fixture 140 by a fixing jig (described later) provided on the mounting fixture 140 so as to overlap the heat insulation panel 160 below the heat insulation panel 160. Therefore, the heat insulation panel 160 is disposed between the heat radiation panel 180 and the mounting fixture 140. Hereinafter, the vertical direction is defined as the z direction, and the longitudinal direction of the air conditioner 110 perpendicular to the z direction is defined as the x direction. The y direction is perpendicular to the x direction and the z direction, and is the front direction of the air conditioner 110. In this specification, the reverse direction (-x direction) with respect to the x direction is also defined as the x direction. The same applies to the y direction and the z direction.

[0029] (1) Air conditioner Schematic front view, top view, and side view of the air conditioner 110 are shown in FIGS. 2A to 2C, respectively. The air conditioner 110 includes a housing 112, and a heat exchanger (not shown), a fan, a control device for controlling the heat exchanger and the fan, a tray and a drain pipe for receiving condensed water, various sensors such as a temperature sensor and a humidity sensor, a wireless receiving unit, etc. are provided in the housing 112. As shown in these figures, the air conditioner 110 includes an air suction port 112a on the front side of the housing 112, that is, on the side opposite to the wall 202. The sucked air is temperature-controlled by the heat exchanger, and then blown out from the air outlet 112b provided on the upper surface of the housing 112 toward the ceiling 200 side and supplied to the spacer 120 (see the arrow in FIG. 2C). In other words, the air conditioner 110 is configured to blow the temperature-controlled air onto the spacer 120 disposed on the ceiling 200 side.

[0030] FIG. 3A shows a schematic front view of a mounting plate 210 according to an embodiment of the present invention that can be used when attaching an air conditioner 110 to a wall 202. As shown in FIG. 3A, the mounting plate 210 has a main plate 212, a pair of arms 216 connected to the main plate 212, and a plurality of through holes 218 used when fixing the main plate 212 to the wall. The mounting plate 210 may further have a rail 214 for hooking the air conditioner 110.

[0031] The main plate 212 and the arms 216 are configured to support the air conditioner 110 and include a relatively strong metal such as stainless steel. The main plate 212 may have notches 212a at the lower right and / or lower left positions when attached to the wall 202. When a hole for piping is provided in the wall 202, by arranging the piping through the notches 212a, it is not necessary to bring out the piping from the side of the air conditioner 110, so the aesthetics of the room can be maintained.

[0032] The main plate 212 is fixed to a stud or the like inside the wall 202 using a fixture 220 such as a screw by utilizing the through holes 218. It is preferable to provide the number of through holes 218 more than the number required for fixing the main plate 212 and the air conditioner 110. Thereby, since the fixture 220 can be struck in flexibly corresponding to the arrangement of the studs, the main plate 212 can be fixed at an arbitrary position on the wall 202.

[0033] The pair of arms 216 is configured to avoid interference between the circumferential edge provided at the upper part of the wall 202 and the mounting plate 210, define the distance between the air conditioner 110 and the ceiling 200, and enable the air conditioner 110 to be arranged horizontally. Therefore, the pair of arms 216 has a first plate 216a extending in a direction away from the wall 202 and a second plate 216b extending in a direction approaching the ceiling when the main plate 212 is attached to the wall 202. The first plate 216a is connected to the main plate 212, and the second plate 216b is connected to the first plate 216a. With this configuration, as shown in FIG. 3B, a space 210a formed by the arm 216 and the ceiling 200 can be formed above the main plate 212, and by utilizing this space 210a, interference between the circumferential edge and the air conditioner 110 or the main plate 212 can be prevented. Also, the height of the arm 216 is adjusted so that the spacer 120 can be inserted into the gap between the air conditioner 110 and the ceiling 200 when the air conditioner 110 is attached to the mounting plate 210. For this reason, by arranging the main plate 212 so that the two second plates 216b contact the ceiling 200 and fixing it to the wall 202, a required predetermined distance between the air conditioner 110 and the ceiling 200 can be maintained. Generally, since the ceiling 200 is constructed at a horizontal or nearly horizontal angle, by using the pair of arms 216, the main plate 212 and the air conditioner 110 can be kept substantially horizontal. The spacer 120 is preferably arranged so as not to contact the second plate 216b and be separated therefrom. Thereby, it is possible to prevent the generation of noise caused by the spacer 120 rubbing against the second plate 216b when the spacer 120 expands or contracts due to temperature changes.

[0034] In the example shown in FIG. 3B, the arm 216 is composed of a first plate 216a and a second plate 216b that are substantially orthogonal to each other. However, as long as the above functions can be realized, the configuration of the arm 216 is not limited. For example, the angle between the first plate 216a and the second plate 216b is also arbitrary, and the second plate 216b may also extend obliquely from the vertical direction. Further, as shown in FIG. 3C, the arm 216 may have a plurality of bent portions. Although not shown, the arm 216 may be curved.

[0035] The rail 214, which has an arbitrary configuration, is provided so as to extend in a horizontal or substantially horizontal direction when the main plate 212 is fixed to the wall 202. The air conditioner 110 is fixed to the main plate 212 by engaging a groove (not shown) provided in the air conditioner 110 with the rail 214.

[0036] (2) Spacer A Overall structure FIG. 4 shows a schematic perspective view of the air conditioner 110 and the spacer 120 disposed thereon, and FIG. 5A shows a schematic perspective view of the spacer in an inverted state. As described above, the spacer 120 is provided so as to overlap the air outlet 112b on the air conditioner 110 and is sandwiched between the air conditioner 110 and the ceiling 200. The spacer 120 is provided so as to contact the air conditioner 110, but it is preferably provided so as not to contact the ceiling 200. For example, by disposing the spacer 120 at a distance of 2 mm or more and 20 mm or less from the ceiling 200, it is possible to prevent the generation of noise that occurs when the ceiling 200 and the spacer 120 rub against each other.

[0037] As shown by the white and solid arrows in FIG. 5A, the spacer 120 is configured to take in the temperature-controlled air in the air conditioner 110 and guide this air to the front side of the air conditioner 110. If this function can be realized, there are no restrictions on the internal structure of the spacer 120. For example, as shown in FIG. 5A, the spacer 120 can include a bottom plate 122 disposed on the ceiling 200 side and side walls 124 connected to the bottom plate 122. The bottom plate 122 and the side walls 124 may be integrated, or the bottom plate 122 and the side walls 124 may be joined to each other as independent members with an adhesive or the like. The structure of the side walls 124 can be arbitrarily determined. The side walls 124 may be configured to block the x-direction on the wall 202 side of the recess 120a and open the side of the heat insulation panel 160. A recess 120a is formed by the bottom plate 122 and the side walls 124, with the front side of the air conditioner 110 (i.e., the side of the heat insulation panel 160) being open, and the spacer 120 is arranged such that the recess 120a overlaps with the air outlet 112b. Thereby, the temperature-controlled air can be selectively supplied in the y-direction, i.e., the front direction of the air conditioner 110, without being diffused in the x-direction to the ceiling 200, the wall 202 side (see the arrows in the figure). To supply the temperature-controlled air more efficiently, as shown in FIG. 5B, the spacer 120 may be configured such that the recess 120a becomes deeper stepwise and / or continuously as it approaches the heat insulation panel 160. Also, although not shown, if the air outlet 112b is displaced from the center of the air conditioner 110 or the spacer 120, the spacer 120 may be configured such that the length of the recess 120a in the x-direction (the length of the recess 120a in the x-direction at the lower surface on the air conditioner 110 side of the side walls 124) increases as it approaches the heat insulation panel 160.

[0038] The spacer 120 preferably guides the temperature-controlled air to the heat-insulating panel 160 while maintaining its temperature. For this purpose, the spacer 120 is configured to include, for example, resins such as expanded polystyrene (styrofoam), expanded polyurethane, polylactic acid, heat-insulating materials such as glass wool, rock wool, gypsum, or a combination of multiple types of these heat-insulating materials. Alternatively, the upper surface and side surfaces of the spacer 120 (i.e., the sides opposite to the recesses 120a of the bottom plate 122 and the side walls 124) are formed as a case having a thickness of 0.5 to 3 mm using a relatively high-strength resin such as polypropylene (i.e., a resin having a higher glass transition temperature compared to the material forming the recesses 120a), and the heat-insulating material described above may be used inside the mold (i.e., the recesses 120a of the bottom plate 122 and the side walls 124). Thereby, the strength for holding the attachment fixture 140 and the heat-insulating panel 160, which will be described later, can be obtained.

[0039] The spacer 120 is further provided with a configuration for assisting the attachment of the attachment fixture 140 and the heat-insulating panel 160. Specifically, as shown in FIGS. 4 and 5A, it includes a plurality of claws 126 used when attaching the attachment fixture 140 and a plurality of visors 128 used when attaching the heat-insulating panel 160.

[0040] i. Claw FIG. 6A shows a schematic top view of a part of the spacer 120, and FIGS. 6B and 6C show schematic end views along the dashed line A-A' of FIG. 6A. As shown in these figures, each of the plurality of claws 126 is a convex portion that extends in the z direction (i.e., in the normal direction of the upper surface) from the upper surface of the spacer 120 toward the ceiling 200 (FIG. 6B). As will be described later, the plurality of hooks 146 of the mounting fixture 140 are formed so as to straddle the plurality of claws 126 and engage with the claws 126 (FIG. 6C). Since the mounting fixture 140 is provided to contact the ceiling 200, the claws 126 are provided at a height such that they do not contact the ceiling 200 when the spacer 120 is installed on the air conditioner 110. For this reason, for example, an extension member 130 that is located under the bottom plate 122 when the spacer 120 is disposed on the air conditioner 110 may be provided, and a step may be provided between the extension member 130 and the bottom plate 122 (FIG. 6B). By providing the claws 126 having a height smaller than the thickness of the bottom plate 122 on the exposed portion 130a of the extension member 130 from the bottom plate 122, the uppermost portion of the claws 126 can be set at a position lower than the uppermost surface of the bottom plate 122.

[0041] The plurality of claws 126 are provided in a straight line, more specifically, at a constant pitch P in the x direction 1 as shown in FIG. 4. The number of the plurality of claws 126 is arbitrary, but is preferably 2 or more and 5 or less, typically 3. The pitch P 1 is set in the range of 20 cm or more and 30 cm or less. Note that the plurality of claws 126 may be integrated with the bottom plate 122 or the extension member 130, or may be fixed to the bottom plate 122 or the extension member 130 as an independent configuration.

[0042] visor The plurality of visors 128 are provided so as to be positioned lower than the plurality of claws 126 when the spacer 120 is installed on the air conditioner 110. The plurality of visors 128 are configured to engage with a plurality of notches provided in the heat insulation panel 160 described later. That is, the plurality of visors 128 are configured to be inserted into the plurality of notches of the heat insulation panel 160. Thereby, the positioning of the heat insulation panel 160 becomes easy, and the heat insulation panel 160 can be easily connected to the spacer 120. Further, by providing the visor 128 at a position lower than the claw 126, interference between the mounting fixture 140 and the heat insulation panel 160 can be prevented.

[0043] The plurality of visors 128 extend from the spacer 120 in the y direction, that is, the front side of the air conditioner 110 (the heat insulation panel 160 side). In the example shown in FIGS. 6A and 6B, the plurality of visors 128 extend from the side surface of the extension member 130 toward the heat insulation panel 160 side. The number of the plurality of visors 128 is arbitrary, but is preferably 2 or more and 5 or less, and typically 3. The number of the plurality of visors 128 may be the same as or different from the number of the plurality of claws 126. The plurality of visors 128 are also arranged at a constant pitch P 2 as shown in FIG. 4. The pitch P 2 may be the same as or different from the pitch P 1 . The plurality of visors 128 and the plurality of claws 126 may be provided such that one visor 128 and one claw 126 exist in one yz plane, or may be provided such that no claw 126 exists in any yz plane including one visor 128. As shown in FIG. 6B and the like, it is preferable that each of the plurality of visors 128 is configured such that the thickness (length in the z direction) decreases as the distance from the spacer 120 increases. By providing such a tapered shape to the plurality of visors 128, interference between the mounting fixture 140 and the visor 128 can be prevented when the mounting fixture 140 is rotated in a state of being engaged with the claw 126.

[0044] (3) Mounting fixture The mounting fixture 140 is fixed to the ceiling 200 on the front side of the air conditioner 110 and functions as a base for fixing the heat insulation panel 160 and attaching the heat radiation panel 180. As shown in the schematic perspective view (FIG. 7A) including the mounting fixture 140, the mounting fixture 140 is composed of a plurality of frames 142. More specifically, the mounting fixture 140 has a first vertical frame 142-1 and a second vertical frame 142-2 that form a square shape, and a first horizontal frame 142-4 and a second horizontal frame 142-5. Both ends of the first horizontal frame 142-4 and the second horizontal frame 142-5 are fixed to the ends of the first vertical frame 142-1 and the second vertical frame 142-2 respectively using welding or fixtures such as screws and bolts. When the rigidity of the mounting fixture 140 is insufficient, one or more additional vertical frames may be provided between the first vertical frame 142-1 and the second vertical frame 142-2, or one or more additional horizontal frames may be provided between the first horizontal frame 142-4 and the second horizontal frame 142-5. In the example shown in FIG. 7A, a third vertical frame 142-3 is provided between the first vertical frame 142-1 and the second vertical frame 142-2. Also, corner plates 144 for increasing the structural strength of the mounting fixture 140 may be arranged on the frames 142 that are connected to each other. Each frame 142 and corner plate 144 may include a polymer material such as polyethylene, polypropylene, or vinyl chloride, or may include a metal such as aluminum, iron, zinc, or copper, or an alloy such as stainless steel or brass.

[0045] The attachment device 140 is fixed to the ceiling 200 by using a fixture such as a screw to fix the attachment device 140 to the soffit provided on the back side of the ceiling 200. Since the arrangement of the soffit varies depending on the room in which the radiant air conditioning system 100 is installed, as shown in the schematic top view of FIG. 8, a plurality of through holes 142a that act as screw holes are provided in each frame 142 so as to be able to accommodate soffits of various arrangements. The arrangement of the through holes 142a can be arbitrarily determined. For example, a plurality of rows in which the plurality of through holes 142a are aligned in the extending direction of the frame 142 may be arranged. In this case, in adjacent rows, the through holes 142a may be staggeredly arranged, or the through holes 142a may be arranged so that each through hole 142a overlaps with the through holes 142a in the adjacent row in a direction perpendicular to the extending direction of the frame. By providing a plurality of through holes 142a, the attachment device 140 can be flexibly fixed to the ceiling 200 according to the arrangement of the soffit 204.

[0046] The attachment device 140 is further provided with a plurality of hooks 146. The plurality of hooks 146 are arranged on the spacer 120 side when the attachment device 140 is attached to the ceiling 200, and are provided on the frame 142 (here, the second horizontal frame 142-5) extending in the x direction. The hook 146 is fixed to the frame 142 by welding or using a fixture such as a screw or a bolt. As shown in the schematic view of the end face along the chain line B-B' in FIG. 8 (FIG. 9A), each hook 146 has a hook-like shape. Further, as shown in FIG. 7B, each hook 146 has a notch 146a that meshes with the above-described claw 126. The width (length in the x direction) of the notch 146a is set to be equal to or greater than the length of the claw 126 in the x direction. The number of the plurality of hooks 146 can also be arbitrarily set, but is larger than the number of the plurality of claws 126 provided on the spacer 120. For example, the number of the plurality of hooks 146 is 4 or more and 6 or less, and typically 5. The plurality of hooks 146 are also arranged at a constant pitch P 3 and the pitch P 3 is the pitch P of the claw 126 1It is the same as. Therefore, all the claws 126 will engage with a continuous part selected from the plurality of hooks 146. As will be described later, by making the numbers of the hooks 146 and the claws 126 different, the position of the mounting device 140 with respect to the air conditioner 110 and the spacer 120 can be changed according to the structure of the room where the radiant air conditioning system 100 is arranged.

[0047] When fixing the mounting device 140 to the ceiling 200, while holding the mounting device 140, engage the hooks 146 of the mounting device 140 with the plurality of claws 126 of the spacer 120 so that the notch 146a of each hook 146 straddles each claw 126 (see the dotted line in FIG. 9B). Thereby, the position of the mounting device 140 is easily determined. Then, rotate the mounting device 140 in the direction of the ceiling 200 with the contact point between the hook 146 and the spacer 120 as the fulcrum. The rotation axis at this time is in the x direction. Then, by fixing the mounting device 140 to the ceiling edge 204 using a screw or the like, the mounting device 140 is fixed to the ceiling 200 (FIGS. 9B and 9C). Since the mounting device 140 can be rotated with the hook 146 engaged with the claw 126, a part of the weight of the mounting device 140 is borne by the spacer 120. For this reason, an operator can rotate the mounting device 140 with one hand and fix the mounting device 140 to the ceiling edge 204 using a screw or the like with the other hand. That is, even a single operator can easily fix the mounting device 140 to the ceiling 200.

[0048] As shown in FIGS. 7A and 8, the mounting device 140 is further provided with a pair of fixing jigs 148 for attaching the heat radiation panel 180 to the mounting device. There is no restriction on the configuration of the fixing jig 148. For example, as shown in FIG. 7A, the fixing jig 148 may be a rail having a pair of horizontal planes and an inclined plane sandwiched therebetween. In this case, a pair of sliders (described later) movable on the pair of rails are provided on the heat radiation panel 180, and by arranging and moving the sliders on the rails, the heat radiation panel 180 can be easily attached to the mounting device 140. Further, the mounting device 140 may further have a magnet 150 located between the fixing jig 148 and the spacer 120 when the mounting device 140 is fixed to the ceiling 200. In this case, by providing an adsorption surface on the heat radiation panel 180, the heat radiation panel 180 can be securely fixed to the mounting device 140 using magnetic force. The adsorption surface is provided at a position corresponding to the magnet 150 when the heat radiation panel 180 is attached to the mounting device 140.

[0049] (4) Heat insulation panel The heat insulation panel 160 is connected to the spacer 120, takes in the temperature-controlled air supplied through the spacer 120, and exchanges heat with the heat radiation panel 180 to heat or cool the heat radiation panel 180. FIGS. 10 and 11A show schematic perspective views of the heat insulation panel 160 when observed from above and below, respectively. As shown in these figures, the length of the heat insulation panel in the x direction is larger than that of the air conditioner 110. The heat insulation panel 160 has a bottom plate 162 and a pair of side walls 164 facing each other, and a flow path 160a for the temperature-controlled air supplied from the spacer 120 is formed by the bottom plate 162 and the side walls 164. The flow path 160a extends from the spacer 120 side in the opposite direction (y direction). In order to efficiently maintain the temperature of the temperature-controlled air, the heat insulation panel 160 is also configured to include resin such as expanded polystyrene (styrofoam), expanded polyurethane, polylactic acid, heat insulation materials such as glass wool, rock wool, and gypsum, or a combination of a plurality of these heat insulation materials.

[0050] Here, as shown in FIG. 12A, a plurality of notches 162a that engage with a plurality of visors 128 of the spacer 120 are provided at a constant pitch P on the bottom plate 162 of the heat insulation panel 160. 4 The plurality of notches 162a are provided at the end of the bottom plate 162 located on the spacer 120 side when the heat insulation panel 160 is fixed to the mounting fixture 140. The number of the plurality of notches 162a is larger than the number of the plurality of visors 128, for example, 5. The pitch P of the plurality of notches 162a 4 is the same as the pitch P of the plurality of visors 128. 2 Therefore, all of the plurality of visors 128 engage with a continuous part of the plurality of notches 162a, and these notches 162a cover the plurality of visors 128. By adopting such an arrangement relationship between the plurality of notches 162a and the plurality of visors 128, the positioning of the heat insulation panel 160 with respect to the spacer 120 becomes easy. Also, as will be described later, the arrangement of the heat insulation panel 160 with respect to the spacer 120 can be changed according to the structure of the room.

[0051] When installing the heat insulation panel 160, the heat insulation panel 160 is hooked on the spacer 120 so as to cover all of the plurality of visors 128 in a continuous part selected from the plurality of notches 162a (see the dotted line in FIG. 12B). Then, with the contact point between the heat insulation panel 160 and the spacer 120 as a fulcrum, the heat insulation panel is rotated toward the mounting fixture 140 side (ceiling 200 side) (see the chain line arrow). The rotation axis of the heat insulation panel 160 at this time is also in the x direction. Then, the heat insulation panel 160 may be fixed to the mounting fixture 140. The method of fixing the heat insulation panel 160 to the mounting fixture 140 can be appropriately selected. For example, as shown in FIG. 11 and a schematic view of the end face along the chain line C-C' thereof (FIG. 11B), a plurality of recesses 162b arranged so as to overlap with the frame 142 of the mounting fixture 140 are provided on the bottom plate 162, and the bottom plate 162 may be fixed to the frame 142 with a fixture 166 such as a screw or a bolt in the recess 162b. Since the heat insulation panel 160 can be rotated with the notch 162a engaged with the visor 128, a part of the weight of the heat insulation panel 160 is borne by the spacer 120. Therefore, an operator can rotate the heat insulation panel 160 with one hand and fix the heat insulation panel 160 to the mounting fixture 140 using a screw or the like with the other hand. That is, even a single operator can easily fix the heat insulation panel 160 to the mounting fixture 140. After fixing the heat insulation panel 160 using the fixture 166, a heat insulation member 167 that closes the recess 162b may be installed. Thereby, it is possible to prevent the temperature-controlled air from heating or cooling the fixture 166, and to prevent condensation and improve the temperature control effect.

[0052] As shown in FIG. 11A, a plurality of pillars 168 are further provided at equal intervals in the heat insulation panel 160. The plurality of pillars 168 may be integrated with the bottom plate 162 or may be fixed to the bottom plate 162 using an adhesive or the like. When the heat insulation panel 160 is attached to the attachment device 140, the plurality of pillars 168 are arranged on the spacer 120 side and extend downward from the bottom plate 162. Preferably, the upper surfaces of the plurality of pillars 168 (the surfaces opposite to the bottom plate 162) are in the same plane as the upper surfaces of the side walls 164 (the surfaces opposite to the bottom plate 162). Further, the plurality of pillars 168 are sandwiched between a pair of side walls 164 and are linearly arranged in the x direction 5 at a pitch P (FIG. 13A). The number of the plurality of pillars 168 can be arbitrarily determined, for example, 3 or more and 5 or less, and typically 4. Also, the pitch P 5 may be the same as or different from the pitch P 4 of the plurality of notches 162a and the pitch P 2 of the plurality of visors 128. However, the distance D 1 between adjacent pillars 168 is the same as the distance D 2 between the adjacent pillar 168 and the side wall 164.

[0053] In addition, a detachable shielding wall 170 that can be fixed between two adjacent pillars 168 and between an adjacent pillar 168 and a side wall 164 is disposed on the heat insulation panel 160 (FIGS. 11A and 13A). Since the shielding wall 170 can be fixed to the bottom plate 162 and the pillar 168 only by frictional force, it can be removed. Preferably, the height of the shielding wall 170 is the same as the height of the pillar 168. Therefore, for example, as shown in FIG. 13A, by providing the shielding wall 170 only between an adjacent pillar 168 and a side wall 164, temperature-controlled air can be introduced from the center (the midpoint between a pair of side walls 164) of the heat insulation panel 160 and the vicinity thereof. Alternatively, as shown in FIG. 13B, by providing the shielding wall 170 only between one side wall 164 and the adjacent pillar 168 and between the adjacent pillars 168, temperature-controlled air can be introduced from a portion offset from the center of the heat insulation panel 160 (see the arrow in the figure). As will be described later, by using a plurality of pillars 168 and a detachable shielding wall 170, even when the heat insulation panel 160 is shifted with respect to the air conditioner 110, temperature-controlled air can be efficiently supplied between the heat insulation panel 160 and the heat radiation panel 180.

[0054] The heat radiation panel 180 is fixed to the mounting fixture 140 via the heat insulation panel 160. For this reason, the heat insulation panel 160 has a pair of openings 162c for exposing a fixing jig 148 or the like used when fixing the heat radiation panel 180 (FIG. 10). The pair of openings 162c are provided so as to overlap with the pair of fixing jigs 148 when the heat insulation panel 160 is fixed to the mounting fixture 140. In addition, a partition wall 172 for shielding the fixing jig 148 from the temperature-controlled air is provided on the heat insulation panel 160 (FIG. 11A). The partition wall 172 surrounds a part of the opening 162c, is connected to the side wall 164, and cooperates with the side wall 164 to surround the entire opening 162c. Preferably, the upper surface of the partition wall 172 (the surface opposite to the bottom plate 162) is in the same plane as the upper surface of the side wall 164 (the surface opposite to the bottom plate 162). Thereby, it is possible to prevent the temperature-controlled air from leaking from the opening 162c, and it is possible to prevent dew condensation due to cooling of the fixing jig 148 and maintain the temperature of the temperature-controlled air.

[0055] (5) Heat radiation panel As shown in FIGS. 1A and 1B, the heat radiation panel 180 is provided under the heat insulation panel 160 such that part or all of the heat insulation panel 160 overlaps the heat radiation panel 180 in the z direction. With this configuration, efficient heat exchange can be achieved between the temperature-controlled air and the heat radiation panel 180, and since the heat insulation panel 160 cannot be visually recognized, the radiation air conditioning system 100 with excellent aesthetics can be provided.

[0056] As shown in FIG. 14A, the heat radiation panel 180 has a frame body 182 assembled by a plurality of frames 184 including metals such as aluminum and stainless steel, or resins such as those exemplified by fiber-reinforced plastics. The arrangement of the plurality of frames 184 is arbitrary, and for example, the plurality of frames 184 are assembled to form a lattice shape. The frame body 182 includes a first frame body 182-1 and a second frame body 182-2, which are connected to be relatively rotatable with respect to each other by a hinge (not shown) (see the arrow in the figure). The second frame body 182-2 is located on the air conditioner 110 side when the heat radiation panel 180 is fixed to the mounting fixture 140.

[0057] As shown in FIG. 14A, a pair of sliders 186 used for fixing to the fixing jig 148 are provided on the first frame body 182-1. The slider 186 is fixed to the frame 184 by a fixture such as welding or screws, and as shown in FIG. 15, includes a pedestal 188 and a slide pin 190. The slide pin 190 is fixed to the pedestal 188. The pedestal 188 is configured to provide a height for the slide pin 190 such that when the slide pin 190 is disposed on the rail of the fixing jig 148 (see FIG. 7), the heat radiation panel 180 and the heat insulation panel 160 are in contact with each other or separated by an appropriate distance (for example, 1 cm or more and 5 cm or less). The slide pin 190 has, for example, a cylindrical shape and is arranged coaxially between the pair of sliders 186.

[0058] On one side, a pair of adsorption surfaces 192 are provided on the second frame body 182-2 at positions corresponding to the magnets 150 (see FIG. 7) provided on the mounting fixture 140. As shown in FIG. 16, in a state where the second frame body 182-2 is folded with respect to the first frame body 182-1, the slide pin 190 is moved toward the air conditioner 110 side on the rail of the fixing jig 148, and then the second frame body 182-2 is rotated with respect to the first frame body 182-1 to adsorb the adsorption surface 192 to the magnet 150, whereby the heat radiation panel 180 including the frame body 182 is fixed to the mounting fixture 140.

[0059] The frame body 182 is accommodated in a bag-shaped cover 194 (FIG. 14B). Since the cover 194 is formed of a fiber material, it has air permeability. For this reason, the temperature-controlled air supplied to the space between the heat insulation panel 160 and the heat radiation panel 180 is taken into the cover 194 and then gradually released from the cover 194. As a result, the wind speed of the temperature-controlled air is weakened, and heat radiation from the temperature-controlled air in the cover 194 or heat absorption by the temperature-controlled air occurs. That is, it is possible to appropriately adjust the indoor temperature without discomfort caused by the wind blown out from the air conditioner 110, because the air released from the radiation air conditioning system 100 is prevented from hitting people forcefully, and the heat radiation or heat absorption caused by the heat radiation panel 180 contributes to the indoor temperature control.

[0060] 2. Construction method of the radiation air conditioning system Although already partially mentioned, the construction method of the radiation air conditioning system 100 will be described below. The radiation air conditioning system 100 fixes the mounting plate 210 to the wall 202 and mounts the air conditioner 110 on the mounting plate 210. Then, the spacer 120 is disposed on the air conditioner 110, and the mounting fixture 140 is fixed to the ceiling 200. Further, the heat insulation panel 160 is connected to the spacer 120 and fixed to the mounting fixture 140, and finally the heat radiation panel 180 is mounted on the mounting fixture 140, whereby the radiation air conditioning system 100 is constructed.

[0061] As described above, the mounting plate 210 is disposed on the wall 202 such that the second plate 216b of the pair of arms 216 contacts the ceiling 200, and is fixed to the wall 202 using the fixture 220. Then, the air conditioner 110 is attached to the mounting plate 210. The spacer 120 is inserted between the air conditioner 110 and the ceiling 200. The spacer 120 may be fixed to the air conditioner 110 using a fixture such as a screw.

[0062] First, the fixing of the mounting fixture 140 is performed by engaging a plurality of hooks 146 with a plurality of claws 126 (see FIGS. 9B and 9C). At this time, the hooks 146 or the frame 142 may interfere with the visor 128. Therefore, by forming the above-described tapered shape on the visor 128, interference between the hooks 146 or the frame 142 and the visor 128 can be prevented, and damage to the visor 128 can be prevented. Then, as indicated by the arrow in FIG. 9C, the mounting fixture 140 is rotated toward the ceiling 200 with the contact point between the plurality of hooks 146 and the plurality of claws 126, or the contact point between the plurality of hooks 146 and the spacer 120 as a fulcrum. Then, the mounting fixture 140 is fixed to the field edge 204 on the ceiling 200 using a fixture such as a screw or a bolt. At this time, among the plurality of through holes 142a provided in the frame 142 constituting the mounting fixture 140, the through hole 142a overlapping the field edge 204 is used (see FIG. 8).

[0063] As described above, the plurality of hooks 146 and the plurality of claws 126 have the same pitch P 1 , P 3It is arranged at. Also, the number of the plurality of hooks 146 is larger than the number of the plurality of claws 126. Therefore, the position of the mounting device 140 can be shifted in the x direction with respect to the air conditioner 110 and the spacer 120 so as to conform to the structure of the room to which the radiant air conditioning system 100 is attached. For example, when the number of the plurality of hooks 146 and the number of the plurality of claws 126 are 5 and 3 respectively, as shown in FIG. 17A, by engaging three consecutive hooks 146 out of the plurality of hooks 146, excluding the hooks 146 at both ends, with the three claws 126, the centers of the air conditioner 110 and the mounting device 140 can be made to coincide in the y direction. On the other hand, depending on the structure of the room, the heat radiation panel 180 may not be able to be arranged when the centers of the air conditioner 110 and the mounting device 140 are made to coincide in the y direction. In this case, as shown in FIG. 17B, the mounting device 140 may be shifted in the x direction with respect to the air conditioner 110 and the spacer 120. That is, the mounting device 140 can be arranged at a position shifted with respect to the centers of the air conditioner 110 and the spacer 120 by engaging three consecutive hooks 146 including the outermost hook 146 with the three claws 126 and fixing the mounting device 140.

[0064] Subsequently, the heat insulation panel is connected to the spacer 120. Specifically, a plurality of visors 128 of the spacer 120 are accommodated in a plurality of notches 162a of the heat insulation panel 160 (see FIG. 12B). Then, as shown by the chain line arrow in FIG. 12B, the heat insulation panel 160 is rotated with the contact point between the heat insulation panel 160 and the visor 128 or the contact point between the heat insulation panel 160 and the spacer 120 as a fulcrum. In a state where the heat insulation panel 160 is in contact with the mounting device 140, the heat insulation panel 160 may be fixed to the mounting device 140 using a fixture (see FIG. 11B).

[0065] As described above, the number of the plurality of notches 162a is larger than the number of the plurality of visors 128. Therefore, the notches 162a used at this time may be determined by the positional relationship between the mounting fixture 140 and the spacer 120. For example, when adopting the layout shown in FIG. 17A, by engaging a plurality of continuous notches 162a excluding the notches 162a at both ends with the visors 128, the centers of the air conditioner 110 and the mounting fixture 140 can be made to coincide in the y direction. On the other hand, when adopting the layout shown in FIG. 17B, a plurality of continuous notches 162a including the outermost notch 162a may be engaged with the visors 128.

[0066] Thereafter, the detachable shielding wall 170 is attached. The position where the shielding wall 170 is attached is determined by the positional relationship between the spacer 120 and the mounting fixture 140. For example, as shown in FIG. 17A, when the centers of the air conditioner 110 and the mounting fixture 140 coincide in the y direction, as shown in FIG. 11A, the shielding wall 170 may be attached between the two side walls 164 and the pillar 168 adjacent thereto, and the space between the adjacent pillars 168 may be left open. On the other hand, as shown in FIG. 17B, when the centers of the mounting fixture 140 and the air conditioner 110 are shifted in the x direction relative to each other, as shown in FIG. 18, the shielding wall 170 may be attached between one side wall 164 and the pillar 168 adjacent thereto, and between this pillar 168 and the pillar 168 adjacent thereto. By appropriately changing the position of the shielding wall 170 in this way, even if the air conditioner 110 and the heat insulation panel 160 are shifted in the x direction, the temperature-controlled air can be effectively supplied to the space between the heat insulation panel 160 and the heat radiation panel 180.

[0067] Thereafter, the heat radiation panel 180 is attached to the attachment fixture 140. Specifically, a pair of sliders 186 are respectively disposed on the rails of a pair of fixing jigs 148 exposed from the opening 162c of the heat insulation panel 160, and are moved in the direction of the spacer 120 (FIG. 16). Thereafter, the second frame body 182-2 is rotated with respect to the first frame body 182-1, and the adsorption surface 192 is magnetically adsorbed to the magnet 150. Thereby, the heat radiation panel 180 is fixed. Note that the opposite side of the first frame body 182-1 with respect to the second frame body 182-2 may be fixed to the attachment fixture 140 with a rope, a magnet, or the like (not shown).

[0068] In the radiation air-conditioning system 100 having the above-described structure, the layouts of the air conditioner 110, the attachment fixture 140, the heat insulation panel 160, and the heat radiation panel 180 can be adjusted to conform to the structure of the room. Therefore, the radiation air-conditioning system 100 can be arranged without being restricted by the structure of the room. Further, in the construction of the radiation air-conditioning system 100, the spacer 120 bears a part of the weights of the attachment fixture 140 and the heat insulation panel 160 that are attached at a high position such as the ceiling 200. Therefore, even a single worker can construct the radiation air-conditioning system 100 without imposing a large load on the work.

[0069] <Second Embodiment> In this embodiment, a modified example of the radiation air-conditioning system 100 described in the first embodiment will be described. Descriptions of configurations that are the same as or similar to those described in the first embodiment may be omitted.

[0070] 1. Spacer Schematic perspective views of the spacer 120 of the radiation air conditioning system 100 according to this embodiment are shown in FIGS. 19A to 20A. FIG. 19A is a schematic perspective view of the spacer 120 seen from above, and FIGS. 19B and 20A are schematic perspective views of the spacer 120 seen from below. As shown in FIG. 20A, the spacer 120 includes a plurality of partition plates 136 disposed in the recess 120a on the side of the heat insulation panel 160 when the spacer 120 is disposed on the air conditioner 110. The partition plates 136 are arranged in the x direction and are provided on the heat insulation panel 160 side of the recess 120a so that the end on the heat insulation panel 160 side coincides with the side surface of the side wall 124. The number of the partition plates 136 is also arbitrary, but is preferably 2 or more and 5 or less, typically 2. However, the pitch P 6 of the plurality of partition plates 136 is the same as the pitch P 5 (FIG. 13A) of the plurality of pillars 168.

[0071] A nozzle unit 132 is attached between two adjacent partition plates 136 and between an adjacent partition plate 136 and the side wall 124. The nozzle unit 132 may be fixed to the recess 120a with a fixture such as a screw or with an adhesive. As shown in FIG. 20B, the nozzle unit 132 has a nozzle 134. The nozzle 134 is a member that connects the recess 120a of the spacer 120 and the flow path 160a of the heat insulation panel 160, and the temperature-controlled air supplied to the recess 120a of the spacer 120 passes through the nozzle 134 and is supplied to the flow path 160a. The nozzle 134 may also be formed of a resin such as polypropylene or polylactic acid. In addition, a heat insulating material such as expanded polystyrene (styrofoam), expanded polyurethane, a resin such as polylactic acid, glass wool, rock wool, gypsum, or a combination of a plurality of these heat insulating materials may be provided inside the nozzle 134.

[0072] A pair of claws 126 are provided above the nozzle 134 of each nozzle unit 132. The pair of claws 126 may be fixed to the nozzle 134 as independent parts or may be integrated with the nozzle 134. As described above, a plurality of partition plates 136 are provided, and the nozzle unit 132 is attached between two adjacent partition plates 136 and between an adjacent partition plate 136 and the side wall 124. Therefore, the spacer 120 will have a plurality of pairs of claws 126. In each nozzle unit 132, the pair of claws 126 are provided such that the hook 146 of the mounting tool 140 is sandwiched therebetween (see FIG. 20B). Also, the claws 126 are provided at a height such that the spacer 120 does not contact the ceiling 200 when the spacer 120 is installed on the air conditioner 110. By providing a plurality of pairs of claws 126, similar to the claws 126 described in the first embodiment, it is easy to determine the position of the mounting tool 140. Also, as shown in FIG. 21A, the hook 146 can be engaged between the pair of claws 126, and then the mounting tool 140 can be rotated in the direction of the ceiling 200 with the contact point between the hook 146 and the spacer 120 as a fulcrum. This enables even a single operator to easily fix the mounting tool 140 to the ceiling 200.

[0073] Details will be described later, but as shown in FIG. 21B, a heat insulation panel 160 is provided so as to cover a part of the nozzle 134. For this reason, in order to prevent leakage of the temperature-controlled air passing through the nozzle 134, a PEF 138 may be provided to cover the lower part and the side surface of the nozzle 134.

[0074] 2. Heat Insulation Panel Fig. 22 shows a schematic perspective view of the heat insulation panel 160 of the radiation air conditioning system 100 according to this modification example as seen from below, and Fig. 23A shows a schematic perspective view of a part thereof as seen from above. The heat insulation panel 160 is provided so as to overlap a part of the nozzle unit 132 attached to the spacer 120. A plurality of pillars 168 provided on the bottom plate 162 of the heat insulation panel 160 are provided such that a part of the nozzle unit 132 is accommodated between two adjacent pillars 168 and between an adjacent pillar 168 and the side wall 164. The number of the plurality of pillars 168 can also be arbitrarily determined, but it is more than the number of the partition plates 136, for example, 3 or more and 5 or less, and typically 4. Also, the distance D 3 between two adjacent pillars 168 and the distance D 4 between an adjacent pillar 168 and the side wall 164 are the same and are set so that a part of the nozzle unit 132 can be accommodated.

[0075] The method of attaching the heat insulation panel 160 is similar to the method described in the first embodiment. As shown in Fig. 23B, the bottom plate 162 is hooked on the nozzle 134 so that a part of the nozzle unit 132 can be accommodated between two adjacent pillars 168 or between an adjacent pillar 168 and the side wall 164. Thereby, the position of the heat insulation panel 160 with respect to the spacer 120 is determined. Then, with the contact point between the bottom plate 162 and the nozzle unit 132 as a fulcrum, the heat insulation panel 160 is rotated in the direction of the ceiling 200 while covering the nozzle unit 132 with the bottom plate 162, and the bottom plate 162 may be fixed to the attachment device 140. By adopting such a method, even a single worker can easily install the heat insulation panel 160.

[0076] As described above, the number of the plurality of pillars 168 is larger than the number of the partition plates 136. Therefore, as shown in FIG. 24A, the plurality of nozzle units 132 may be accommodated only between the adjacent pillars 168, or as shown in FIG. 24B, one nozzle unit 132 may be accommodated between an adjacent pillar 168 and the side wall 164, and the other two may be accommodated between the adjacent pillars 168. For this reason, it is possible to appropriately change the relative positional relationship between the heat insulation panel 160 and the air conditioner 110 according to the structure of the room where the radiation air conditioning system 100 is installed.

[0077] Between the adjacent pillars 168 where the nozzle unit 132 is not accommodated and between the adjacent pillar 168 and the side wall 164, the shielding wall 170 described in the first embodiment may be provided. Alternatively, as shown in FIG. 23A, a through hole 162d that does not overlap with the pillar 168 may be provided in the bottom plate 162 of the heat insulation panel 160, and the detachable shielding wall 170 may be inserted into the through hole 162d (FIGS. 25A and 25B). The shielding wall 170 is configured such that the lower end thereof coincides with the lower end of the side wall 164 between the pillars 168 where the nozzle unit 132 is not accommodated or between the pillar 168 and the side wall 164. On the other hand, between the pillars 168 where the nozzle unit 132 is accommodated or between the pillar 168 and the side wall 164, the length of the shielding wall 170 is adjusted so as not to impede the flow of the temperature-controlled air. For example, the length of the shielding wall 170 may be the same as the thickness of the bottom plate 162. Note that depending on the number of the nozzle units 132 and the number of the pillars 168, there is always a pair or a plurality of pairs of pillars 168 that sandwich the nozzle unit 132 without depending on the positional relationship between the heat insulation panel 160 and the spacer 120. In this case, the through hole 162d may not be provided between these pillars 168 (see FIGS. 23A and 25A).

[0078] In the heat insulation panel 160 described in the first embodiment, the fixing jig 148 and the magnet 150 provided on the mounting fixture 140 are exposed from the opening 162c provided in the bottom plate 162 and shielded from the temperature-controlled air by the shielding wall 170 and the side wall 164 of the heat insulation panel 160. The heat insulation panel 160 according to the present embodiment does not necessarily have such a configuration. As shown in FIG. 26, a notch 162e may be provided in the bottom plate 162 of the heat insulation panel 160, and the heat insulation panel 160 may be arranged so that the fixing jig 148 and the magnet 150 overlap the notch 162e. In this case, the shielding wall 170 is not provided, and the side wall 164 is provided so as to extend along the notch 162e (FIG. 27). With such a structure, the fixing jig 148 and the magnet 150 are shielded from the temperature-controlled air, and heat conduction to the fixing jig 148 and the magnet 150 is prevented. In this structure, the fixing jig 148 and the magnet 150 are exposed from the heat insulation panel 160 in the horizontal direction (FIG. 28), but since the heat radiation panel 180 is larger than the heat insulation panel 160, it is not visible. Therefore, even if this structure is adopted, the aesthetic appearance is not impaired.

[0079] <Third Embodiment> In the present embodiment, a modified example of the radiant air conditioning system 100 described in the first and second embodiments will be described. Regarding configurations that are the same as or similar to those described in the first and second embodiments, the description may be omitted.

[0080] A schematic top view of a part of the spacer 120 of the radiant air conditioning system 100 according to the present embodiment is shown in FIG. 29A, and schematic end views are shown in FIGS. 29B and 29C. As shown in these figures, in the radiant air conditioning system 100 according to the present embodiment, each of the plurality of claws 126 is provided so as not to contact the bottom plate 122 and to be separated from the bottom plate 122. For this reason, a gap 120b extending in the x direction is formed on the spacer 120 (FIG. 29B). The plurality of hooks 146 of the mounting fixture 140 are inserted into the gap 120b while covering the plurality of claws 126, thereby engaging with the claws 126 (FIG. 29C). Therefore, unlike the hook 146 of the mounting fixture 140 described in the first embodiment, in the present embodiment, the hook 146 does not necessarily need to be provided with a notch 146a (see FIG. 7B).

[0081] When fixing the mounting fixture 140 to the ceiling 200, while holding the mounting fixture 140, a part of the mounting fixture 140 is placed on the spacer 120 such that each hook 146 straddles each claw 126 and a part of each hook 146 is inserted into the gap 120b (see the dotted line in Fig. 29C). Thereby, the position of the mounting fixture 140 is easily determined. Thereafter, as described in the first embodiment, the mounting fixture 140 may be rotated in the direction of the ceiling 200 with the contact point between the hook 146 and the spacer 120 as a fulcrum (see Figs. 9B and 9C). Also in this case, since the mounting fixture 140 can be rotated with the hook 146 engaged with the claw 126, a part of the weight of the mounting fixture 140 is borne by the spacer 120. For this reason, an operator can rotate the mounting fixture 140 with one hand and fix the mounting fixture 140 to the edge 204 using a screw or the like with the other hand. That is, even a single operator can easily fix the mounting fixture 140 to the ceiling 200.

[0082] <Fourth Embodiment> In this embodiment, a modified example of the radiant air conditioning system 100 described in the first to third embodiments will be described. For configurations that are the same as or similar to those described in the first to third embodiments, the description may be omitted.

[0083] In the radiant air conditioning system 100 according to this embodiment, as in the third embodiment, a plurality of claws 126 are provided on the spacer 120, and the plurality of claws 126 are provided so as to be separated from the bottom plate 122 such that the gap 120b is formed. On the other hand, as shown in Figs. 30A and 30B, different from the radiant air conditioning system 100 according to the first to third embodiments, a single hook 146 is provided on the mounting fixture 140 of the radiant air conditioning system 100 according to this embodiment. The hook 146 is provided so as to cover at least two, preferably three or more claws 126 at the same time. For this reason, the length (length in the x direction) L of the hook 146 is equal to or greater than the sum of the length (length in the x direction) of one claw 126 and the pitch P 1 and preferably, the length of one claw 126 and the pitch P 1 doubled (2P1 ) The hook 146 is attached to the second horizontal frame 142-5 so as to be as described above.

[0084] By adopting such a configuration, regardless of the position of the claw 126, the mounting device 140 can be slid in the x direction along the gap 120b in a state where the claw 126 and the hook are engaged with each other (see the solid line arrow in Fig. 31). Therefore, the position of the mounting device 140 with respect to the air conditioner 110 and the spacer 120 can be adjusted steplessly. For this reason, the layouts of the heat insulation panel 160 and the heat radiation panel 180 can be adjusted more flexibly with respect to the structure of the room.

[0085] Each of the embodiments described above as embodiments of the present invention can be implemented in appropriate combination as long as they do not conflict with each other. Based on each embodiment, those in which those skilled in the art appropriately add, delete, or change the design of the components are also included in the scope of the present invention as long as they have the gist of the present invention.

[0086] Even other operational effects different from the operational effects brought about by each of the above-described embodiments, those that are obvious from the description in this specification or those that can be easily predicted by those skilled in the art are naturally understood to be brought about by the present invention.
