Description

The present invention relates to a radiant panel unit for use in a radiant air conditioning system, and a radiant air conditioning system using the same.

Convection type air conditioners have been widely used to maintain a comfortable indoor environment in air conditioners. In this system, conditioned air with adjusted temperature and humidity is blown into the room to condition the air by convection.
However, the convection method can easily leave people feeling dissatisfied in terms of comfort.
One of the reasons is that when air is circulated, a temperature difference occurs between the top and bottom of the room, with warm air tending to go to the ceiling and cold air tending to stay on the floor. This is the opposite of the healthy and comfortable feeling of having a cool head and warm feet, so it inevitably feels uncomfortable.
Another reason people are easily dissatisfied is the phenomenon known as a draft, where the circulated air hits the human body directly. For example, it is said that in an air-conditioned room, the perceived temperature drops by 3°C when the wind speed is 0.5 m/s. For this reason, when you go from the blazing sun outside into an air-conditioned room, you may feel comfortable at first, but after your body cools down, you will end up feeling colder.
Also, many people find the idea of air currents directly hitting their body uncomfortable.

Radiation type air conditioners improve the above-mentioned disadvantages of convection type air conditioners in that the airflow is not directed directly at the body.
As an example of such a radiant air conditioning device, Patent Document 1 discloses an air conditioning device (which Patent Document 1 calls a "radiant air conditioning system") that has an air conditioner and a flat, hollow case attached to the ceiling surface.
The air conditioner used in this air conditioning system takes in air from the indoor space and blows out the conditioned air from an air outlet. The radiant panel forms an air passage between the moisture-permeable radiant panel and the heat-insulating panel that are arranged facing each other. The air conditioner and the radiant panel are attached to the ceiling surface so that the air outlet faces the inlet of the air passage (see paragraphs [0025] to [0029] and Figures 1 and 2 of Patent Document 1).
In an air conditioner having such a structure, conditioned air blown out from an air outlet of the air conditioner is introduced into the air passage and circulates through the air passage, thereby controlling the temperature of the radiant panel and performing radiant heating and cooling.

JP 2016-217630 A

A radiant air conditioner cools or heats an indoor space by radiating heat from a radiant panel. The radiant panel only radiates heat in the area that contacts the air-conditioned air flow path that connects to the air conditioner's air outlet. The area from which the radiant panel can radiate heat depends on the area of the flow path. For this reason, no matter how large the area of the radiant panel is, the area available for heat radiation cannot be expanded.

On the other hand, in order to achieve optimal air conditioning performance, the area from which heat is radiated must be increased in proportion to the size of the indoor space.
The problem at this time is the increase in size of the members that form the flow path of the conditioned air, for example, the panel members such as the "heat dissipation panel 222" of Patent Document 1.
In order to increase the heat radiation area, it is necessary to increase the contact area of the radiation panel with the flow path, which requires the panel material to be made larger. Increasing the size of the panel material increases the material cost, and also increases the cost required for transportation and storage. Furthermore, the larger the panel material, the more difficult it becomes to handle, which reduces the operability of various operations.
Some kind of improvement is needed.

The objective of the present invention is to make it possible to increase the area over which a radiant panel radiates heat.

One aspect of the radiating panel unit comprises a back panel attached to a ceiling surface, a radiating panel with a frame covered in a breathable bag-shaped cloth, and a pair of side walls interposed between the back panel and the radiating panel, the radiating panel having a radiating surface whose horizontal projection plane is wider than the width of the back panel, and a surface located between the radiating surface and the back panel and having an opening whose horizontal projection plane is narrower than the width of the back panel, the pair of side walls facing each other in the width direction of the back panel with the opening between them.

One aspect of a radiant air conditioning device is equipped with an air conditioner that is installed on a ceiling or wall surface and blows out conditioned air, a back panel that is attached to the ceiling surface, a radiant panel with a frame covered with a breathable bag-shaped cloth, and a pair of side walls that are interposed between the back panel and the radiant panel, and the radiant panel has a radiant surface whose horizontal projection plane is wider than the width of the back panel, and a surface that is located between the radiant surface and the back panel and has an opening whose horizontal projection plane is narrower than the width of the back panel, and the pair of side walls face each other in the width direction of the back panel with the opening between them, and define a space that serves as a flow path for the conditioned air from an inlet that introduces the conditioned air to an outlet.

According to the present invention, the horizontal projection of the radiation surface provided on one side of the hollow radiation panel is wider than the width of the rear panel, so that the heat radiation area of the radiation panel can be expanded beyond the width of the air-conditioning air flow path defined by the pair of side walls.

1. Radiant Air Conditioner As shown in Fig. 1, the radiant air conditioner 11 of this embodiment comprises an air conditioner 51 and a radiant panel unit 101, both of which are installed on the ceiling surface C.

In this embodiment, the directions of these air conditioners 51 and radiant panel units 101 are defined as the direction perpendicular to the paper surface in Figure 1 as the horizontal direction (width direction), the left-right direction of the paper surface as the depth direction, and the top-bottom direction of the paper surface as the height direction.
The width, depth, and height directions of the housing 51a of the air conditioner 51, the panel base 111 (rear panel 112, side wall 113) that constitutes the radiating panel unit 101, and the radiating panel 131 (frame 132, cloth cover 141) also conform to the above regulations (see Figures 2 to 4).
Thus, when referring to both sides of each part, it means both sides in the lateral width direction (width direction) of each part.
In FIG. 1, the front surface of the air conditioner 51 is the right side, and the rear surface is the left side.
In Fig. 1, the front side and leading edge side of the radiation panel unit 101 and its components are on the right side, and the rear side and trailing edge side are on the left side. Therefore, the leading edge of the radiation panel unit 101 and its components is the end on the right side in Fig. 1, and the trailing edge is the end on the left side in Fig. 1.

(1) Air Conditioner The ceiling surface C is a raised ceiling and has a recess C1 (see also Figs. 10 and 11). An air conditioner 51 is attached by, for example, a hanging bolt so as to fit into this recess C1 (see Fig. 10).
The air conditioner 51 includes a thin housing 51a, the dimensions of which decrease in order of width, depth, and height, and houses various components therein.
The air conditioner 51 having such a shape takes in air from the room R through an air intake 52 provided on the back side, passes through a heat exchanger 53, and blows out the conditioned air from an outlet 55 by a blower 54. A filter 56 is attached to the air intake 52 in a freely detachable manner.
The air conditioner 51 is mounted so as to fit into the recess C1 of the ceiling surface C, and the air outlet 55 is positioned along an edge E that forms the boundary between the ceiling surface C and the recess C1.

(2) Radiating Panel Unit The radiating panel unit 101 is composed of a panel base 111 and a radiating panel 131.

2, the panel base 111 is a heat insulating member having a pair of side walls 113 extending from both sides of a rectangular, flat rear panel 112. For example, resin, gypsum, urethane, glass wool, rock wool, etc. can be used as the material for the panel base 111.
The pair of side walls 113 are raised from both ends of the long side direction (width direction) of the rear panel 112, i.e., from both side ends, and wrap slightly around in the width direction along the long side. Therefore, due to their shape, three sides are open: an area on one end side of the pair of side walls 113, an area on the other end side, and an area facing the rear panel 112 on one side. For ease of explanation, the area on one end side of the pair of side walls 113 will be called the inlet 114, the area on the other end side will be called the outlet 115, and the area facing the rear panel 112 will be called the facing area 116. The facing area 116 is an area in a plane including the upper end faces of the pair of side walls 113.

Therefore, the panel base 111 has a rear panel 112 as a base, and a side wall 113 that rises from the rear panel 112 in an enclosed shape, leaving only an inlet 114 and an outlet 115. The panel base 111 is installed with the inlet 114 connected to the air outlet 55 of the air conditioner 51, with the open facing area 116 on one side facing the room R.

The panel base 111 is provided with a pair of stoppers 117 located at the outlet 115. This distributes the outlet 115 into three locations: one wide location in the center and two narrow locations on both sides. These stoppers 117 are formed by stopper fittings 119 fixed to the back panel 112.
The stopper fitting 119 functions as a connector and is provided with a connector groove 119a.

As shown in FIG. 1, the panel base 111 is attached to the ceiling surface C along the edge E that forms the boundary between the ceiling surface C and the recess C1, so that the inlet 114 is positioned with a gap between it and the air conditioner 51. Any type of attachment means can be used to attach the panel base 111 to the ceiling surface C. For example, screws, hook-and-loop fasteners, adhesive tape, adhesion, etc. can be used, and depending on the structure of the ceiling surface C, attachment means such as hanging bolts can also be used.

Such a panel base 111 is integrally molded, for example, from EPS. Therefore, the entire panel functions as a thermal insulator.

(b) Radiating Panel As shown in FIGS. 3 and 4, the radiating panel 131 is formed by covering a rectangular frame 132 with a bag-shaped cloth cover 141 .

The frame 132 is formed by connecting a number of rod-shaped members 133 and forming them into a rectangular shape with ribs for reinforcement and anti-rotation. Some of the rod-shaped members 133 are used as outer frame members 133a assembled into a rectangular shape that determines the outer shape of the frame 132, and the other parts are used as reinforcing members 133b that reinforce the outer frame. As an example, the rod-shaped members 133 are made of aluminum pipes in the shape of a hollow pillar, which are connected with resin connectors and fastened with screws to form the frame 132.
As another example, the rod-shaped member 133 may be molded from resin or made of carbon.
Such a frame 132 includes a first frame 134 and a second frame 135 .
The first frame 134 is disposed in an area facing the air conditioner 51. The width of the first frame 134 is set to be wider than the air conditioner 51.
The second frame 135 is larger in both the width and depth directions than the panel base 111, and its rear end in the depth direction is long enough to reach the rear depth portion of the underside of the air conditioner 51.
The first frame 134 is connected to the rear end of the second frame 135 by a hinge 136 and is rotatable relative to the second frame 135 (see FIGS. 3 and 6). The first frame 134, together with the rear end of the second frame 135 in the depth direction, has a size sufficient to completely cover the air conditioner 51.

The cloth cover 141 has a bag shape like a futon cover. In other words, it has a shape with three sides closed and one side open. The open side is an open edge 142, from which the frame 132 can be stored. A zipper 143 is attached to the open edge 142, and the open edge 142 can be opened and closed freely by using the zipper 143. The open edge 142 is located slightly inward from the end of the cloth cover 141.
Such a cloth cover 141 is made of cloth, i.e., fiber, and has breathability and elasticity.
Therefore, the cloth cover 141 is formed to be slightly smaller than the frame body 132 in the width direction and depth direction, and maintains a stretched state when the frame body 132 is stored.
The bag-shaped cloth cover 141 can also be considered as an endless shape when viewed as a shape that envelops the width direction of the frame body 132. This is because the bag-shaped shape results from closing one end of an endless shape that is open at both ends.

The bag-shaped cloth cover 141 has a sewn structure of a front-side fiber material exposed to the interior R side and a back-side fiber material facing the flow path 151. For ease of explanation, the front-side fiber material is called front fiber 141A (see also Figs. 17 and 18), and the back-side fiber material is called back fiber 141B.
The surface fibers 141A are exposed to the room R side when the radiant panel 131 is installed, and determine the appearance of the radiant air-conditioning device 11. Therefore, when selecting the material for the surface fibers 141A, an aesthetic viewpoint is important.
The material of the back surface fiber 141B is selected from the viewpoint of minimizing resistance to the airflow when the airflow blown out from the air outlet 55 of the air conditioner 51 is guided to the back side of the surface fiber 141A. From this viewpoint, in this embodiment, a mesh cloth, that is, a fiber of a mesh material, is used as the back surface fiber 141B.
3 and 4, the surface fiber 141A extends to the back side facing the rear panel 112 and is sewn to the back fiber 141B on the back side. The fabric cover 141 is positioned at the stitching portion SP so as to be aligned with the pair of side walls 113 when the radiation panel 131 is attached to the panel base 111.

The radiating panel 131, in which the frame body 132 is covered with the cloth cover 141, is rotatable even when covered with the cloth cover 141, because the first frame body 134 and the second frame body 135 are rotatable about an axis passing through the hinge 136. For ease of explanation, the portion of the radiating panel 131 where the cloth cover 141 covers the first frame body 134 is called the first panel 131A, and the portion where the cloth cover 141 covers the second frame body 135 is called the second panel 131B.
The first panel 131A serves as an area facing a part of the air conditioner 51 .
The second panel 131B is responsible for an area facing the remaining part of the air conditioner 51 and the entire surface of the panel base 111.

1, the radiant panel 131 is positioned and fixed to the facing region 116 of the panel base 111. This defines a space extending from the inlet 114 to the outlet 115, which becomes a flow path 151 for conditioned air.
As shown in Fig. 5(a), the radiating panel 131, in which the fabric cover 141 is covered on the frame 132, forms a hollow shape with one side made of the surface fiber 141A and the opposite side made of the back surface fiber 141B. At this time, the radiating panel 131 creates a state equivalent to having an opening O on the back surface side, since the back surface fiber 141B of the fabric cover 141 is a mesh cloth. Therefore, the conditioned air flowing through the flow path 151 freely enters the inside of the radiating panel 131 from the back surface fiber 141B and comes into contact with the inside of the surface fiber 141A. Therefore, the surface fiber 141A, which is naturally breathable, functions as the radiating surface RS.

As described above, the frame 132 of the radiating panel 131 has a larger projected area than the air conditioner 51 and the panel base 111. More specifically, the width of the first frame 134 is set to be wider than the air conditioner 51, and the width and depth of the second frame 135 are set to be larger than the width and depth directions of the panel base 111. Therefore, the radiating panel 131 has a larger horizontal projected area than the combined area of the air conditioner 51 and the panel base 111.
In this case, as shown diagrammatically in FIG. 5(a), the radiation panel 131 is hollow due to the cloth cover 141 that covers the frame body 132, and therefore, due to the above-mentioned dimensional relationship, the radiation surface RS on the surface fiber 141A side is wider than the width of the rear panel 112.
In contrast, the opening O is narrower than the width of the rear panel 112, which coincides with the opposing distance between the pair of side walls 113. In other words, the pair of side walls 113 are interposed between the rear panel 112 and the radiating panel 131 along the direction in which the conditioned air is blown out from the air outlet 55 of the air conditioner 51, and face each other with the opening O interposed therebetween without protruding. As a result, the width of the flow path 151 of the conditioned air is defined by the pair of side walls 113, and the flow path 151 communicates with the internal space of the radiating panel 131 without leaking the conditioned air from the opening O to the outside.

As shown typically in Fig. 5(b), rod-shaped members 133 of a frame body 132 are positioned in the internal space of the radiant panel 131. Of these rod-shaped members 133, an outer frame member 133a of a first frame body 134 and an outer frame member 133a of a second frame body 135 are positioned vertically directly below a heat exchanger 53 built into the air conditioner 51. The housing 51a of the air conditioner 51 has a flat lower surface, and is in close contact with the frame body 132 via a cloth cover 141.
Of the first frame 134 and second frame 135 that are in close contact with the underside of the housing 51a, the outer frame member 133a of the second frame 135 connected to the first frame 134 functions as a rod-shaped contact member RM. The rod-shaped contact member RM is a part of the outer frame member 133a, and comes into close contact with the housing 51a of the air conditioner 51 via the fabric cover 141. It comes into close contact with the underside of the housing 51a. The structure for bringing the part of the outer frame member 133a that serves as the contact member RM into close contact with the housing 51a will be described later.
Such a sealing member RM divides the internal space of the radiant panel 131 and prevents the conditioned air from flowing around to the rear side of the air conditioner 51 (the side of the air intake 52 ) relative to the heat exchanger 53 .

(c) Structure for attaching and detaching the radiating panel to the panel base As shown in Figures 3, 4, and 6(a) and (b), the frame body 132 is provided with a pair of sliders 137, a pair of connecting pins 138 as connecting devices, and a pair of suction plates 139 as suction members, as structures for temporarily fastening and fixing the radiating panel 131.

The pair of sliders 137 cooperate with a pair of rails 57 (described later) to temporarily fasten the radiating panel 131 .
The pair of connecting pins 138 cooperate with the above-mentioned stoppers 117 and are components for permanently fixing the radiating panel 131 .
The pair of attraction plates 139 are components for holding the first panel 131A of the radiation panel 131 in cooperation with magnets MG, which will be described later.

(Temporary fixing structure of radiation panel)
As shown in FIGS. 3, 4, 6A, and 7 to 9, the temporary fixing structure of the radiating panel 131 is composed of a pair of rails 57 and a pair of sliders 137.
The pair of sliders 137 are fixed to the outer frame member 133a constituting the contact member RM of the second frame 135. The fixed positions are positions near both ends of the outer frame member 133a.
The slider 137 has a round bar-shaped pin 137b fixed to a metal plate 137a for screwing to the outer frame member 133a. The metal plate 137a positions the pin 137b at a position higher than the outer frame member 133a. The pin 137b is disposed in the width direction of the radiation panel 131, that is, along the direction of the rotation axis of the first frame body 134 and the second frame body 135.
As shown in Fig. 8, a pair of rails 57 are attached to the rear lower positions on both side surfaces of the housing 51a of the air conditioner 51. These rails 57 extend in the direction in which the air conditioner 51 and the panel base 111 are arranged, and have steps 57a. The step 57a is lower on the panel base 111 side and higher on the air conditioner 51 side.

The distance between the pins 137b of the pair of sliders 137 is set to be slightly wider than the width dimension of the housing 51a of the air conditioner 51. This makes it possible to guide the pair of sliders 137 from above the pair of rails 57 and place the pins 137b on the rails 57 (see Figures 12 and 13).
The pin 137b placed on the rail 57 is freely slidable on the rail 57. At this time, the pin 137b climbs over the step portion 57a, changing the height of the slider 137, in other words, the height of the radiating panel 131. When the slider 137 moves from the panel base 111 side to the air conditioner 51 side, the radiating panel 131 is positioned at a higher position. When the slider 137 moves from the air conditioner 51 side to the panel base 111 side, the radiating panel 131 is positioned at a lower position. The radiating panel 131 positioned at a higher position brings the outer frame member 133a of the second frame body 135, which is the contact member RM, into close contact with the housing 51a of the air conditioner 51 via the cloth cover 141.

As shown in Figures 8 and 9, restricting pieces 57b are provided at both ends of the rail 57. These restricting pieces 57b prevent the pin 137b, which slides along the rail 57, from falling off.

(Permanent fixing structure of radiation panel)
As shown in FIGS. 2 to 4 and 6B, the main fixing structure of the radiating panel 131 is composed of a pair of stoppers 117 and a pair of connecting pins 138.
The pair of connecting pins 138 are fixed to the second frame body 135. The fixing positions are a pair of reinforcing members 133b connected to the outer frame member 133a on the side opposite to the side connected to the first frame body 134. Of these reinforcing members 133b, the connecting pins 138 are attached to positions relatively close to the outer frame member 133a.
The pair of connecting pins 138 have the form of studs that fit into connecting grooves 119a of a pair of left and right stoppers 117 provided on the panel base 111. The connecting grooves 119a are located at the exhaust port 115 of the radiating panel unit 101 and open to the room R side. Therefore, the connecting pins 138 fit into the connecting grooves 119a of the stoppers 117 by the horizontal movement of the radiating panel 131 from the panel base 111 toward the air conditioner 51.
The stopper 117 and the connecting pin 138 constitute a connecting portion CN that detachably connects the air conditioner 51 and the panel base 111 in response to the movement of the air conditioner 51 and the panel base 111 in the arrangement direction.

(First Panel Retention Structure)
As shown in FIGS. 1, 3, 4, and 6A, the holding structure for the first panel 131A is made up of a pair of magnets MG (panel holding portion) and a pair of attraction plates 139 (attached members).
The pair of suction plates 139 are fixed to two reinforcing members 133b provided on the first frame 134. The fixed positions are slightly lower than the pins 137b of the slider 137 when the first frame 134 and the second frame 135 are arranged on the same plane. These suction plates 139 position the flat suction surfaces 139a horizontally when the first frame 134 stands horizontally.
A pair of magnets MG are provided on the rear surface of the air conditioner 51. The magnets MG are installed at positions near both ends. These magnets MG are attached facing downward.
These magnets MG and attraction plate 139 are positioned so that when the first panel 131A is raised horizontally with the radiating panel 131 in a fully fixed state, the attraction surface 139a of the attraction plate 139 faces the magnet MG and is attracted by magnetic force.

(Innovative cloth cover)
By providing a structure for attaching and detaching the radiating panel 131 to the panel base 111, unevenness occurs in the frame 132 of the radiating panel 131. These are the locations of the slider 137, the connecting pin 138, and the suction plate 139.
If the cloth cover 141 were structured to cover the frame body 132 together with these other parts, not only would the attachment and detachment of the cloth cover 141 to the frame body 132 be complicated, but the functions of these other parts would not be able to be performed normally.
Therefore, the cloth cover 141 has exposure openings at the locations of the slider 137, the connecting pin 138, and the suction plate 139 so that these components can be exposed. The exposure openings are not shown in the drawings.

2. Installation Procedure The installation procedure for the radiant air-conditioning device 11 will be described.

(1) Installation of Air Conditioner First, as shown in FIG. 10, the air conditioner 51 is installed in a recess C1 provided in a ceiling surface C that is a raised ceiling.
If a recess C1 is provided in advance, this is utilized, and if a recess C1 is not provided, the ceiling surface C is worked on to create a recess C1.

(2) Attachment of Panel Base The panel base 111 is attached to the ceiling surface C as shown in FIG.
The panel base 111 is aligned and fixed to the ceiling surface C so that the inlet 114 is positioned at an edge E that forms the boundary between the ceiling surface C and the recess C1.
At this time, the air inlet 114 of the panel base 111 is positioned along the edge E that forms the boundary between the ceiling surface C and the recess C1. As a result, the air outlet 55 of the air conditioner 51 and the air inlet 114 of the panel base 111 are aligned and communicate with each other (see also FIG. 1).

(3) Attaching the Radiating Panel (a) Temporary Fixing First, the radiating panel 131 is temporarily fixed.
As shown in Fig. 12, a pair of sliders 137 (see Fig. 4, etc.) provided on the radiating panel 131 are brought close to the rails 57 provided on both sides of the air conditioner 51, and as shown in Fig. 13, the sliders 137 are placed on the rails 57, thereby temporarily fixing the radiating panel 131. The sliders 137 are placed on a low position located in front of the rails 57.
In the temporarily fixed state, the radiating panel 131 is free to rotate without being restricted in position by either the second frame 135 or the first frame 134 .

(b) Rotation of the Second Panel As shown in FIG. 14, after the radiating panel 131 is temporarily fixed, the second panel 131B is rotated so as to be horizontal.
At this time, the pair of sliders 137 are placed on a lower portion of the pair of rails 57. The connecting pin 138 of the second panel 131B faces the stopper metal fitting 119 of the panel base 111 with a gap therebetween.

15, after the second panel 131B is adjusted to be horizontal, the second panel 131B is pushed in while maintaining the same posture. In other words, the radiant panel 131 is moved toward the air conditioner 51.
As a result, the connecting pin 138 fits into the connecting groove 119a of the stopper fitting 119, and the radiating panel 131 is finally fixed.
At this time, the slider 137 slides on the rail 57, climbing over the step 57a and being positioned at a higher height. This causes the tip side of the radiation panel 131, i.e., the end side of the second panel 131B connected to the first panel 131A, to be raised and pressed against the lower surface of the housing 51a of the air conditioner 51. As a result, the outer frame member 133a, which is the contact member RM of the second frame 135, comes into contact with the lower surface of the housing 51a via the cloth cover 141.
When the radiating panel 131 is permanently fixed, the first panel 131A is free to rotate by the hinge 136 and hangs down vertically.

(d) Holding the First Panel As shown in FIGS. 16 to 18, the first panel 131A is rotated to be horizontal.
Then, the magnet MG provided on the rear surface of the air conditioner 51 magnetically attracts the attraction surface 139a of the attraction plate 139 provided on the first panel 131A, and the first panel 131A is attracted to the magnet MG via the cloth cover 141. This holds the first panel 131A in place and keeps it horizontal.
As the first panel 131A remains horizontal, the fabric cover 141 is pulled by the first frame 134 and maintained in a taut state.
In this manner, the installation of the radiation panel 131 is completed.

(4) Removing the Radiating Panel (a) Releasing the Holding of the First Panel As shown in FIG. 17, the first panel 131A is rotated against the attractive force of the attraction plate 139 caused by the magnetic force of the magnet MG.
Then, as shown in FIG. 15, when the hand is released, the first panel 131A rotates freely and hangs down vertically.

(b) Release of Connection Portion The second panel 131B is grasped and pulled so as to change from the state shown in Fig. 15 to the state shown in Fig. 14. In other words, the radiant panel 131 is moved from the air conditioner 51 toward the panel base 111.
As a result, the connecting pin 138 falls out of the connecting groove 119a of the stopper fitting 119, and the permanent fixation of the radiating panel 131 is released.
At this time, the slider 137 slides on the rail 57, climbing over the step 57a and being positioned at a lower height. This also lowers the position of the tip side of the radiating panel 131, i.e., the end side of the second panel 131B connected to the first panel 131A, and moves away from the bottom surface of the housing 51a of the air conditioner 51. As a result, the state in which the outer frame member 133a, which is the contact member RM of the second frame body 135, is in contact with the bottom surface of the housing 51a via the cloth cover 141 is also released, and the radiating panel 131 is temporarily fixed.

(c) Rotation of the Second Panel As shown in FIG. 13, the second panel 131B is rotated about the pin 137b of the slider 137 placed on the rail 57 as a starting point, and is set in an inclined state.

(d) Removal The second panel 131B is grasped at both ends and the slider 137 is lifted up from the rail 57 to remove it.
This completes the removal of the radiation panel 131.

3. Effects When the air conditioner 51 is operated, conditioned air is blown out from the air outlet 55, passes through the flow path 151, and flows from the inlet 114 to the outlet 115. The conditioned air then adjusts the temperature of the radiant panel 131. It is heated during heating and cooled during cooling. This provides radiant air conditioning to the room R.

(1) Prevention of Condensation During cooling, the radiant air-conditioning device 11 of this embodiment suppresses the occurrence of condensation on the radiant panel 131.
The reasons for this will be explained in detail.

(a) Causes of condensation The air contains moisture in the form of gas (water vapor).
The state in which air contains water vapor to the maximum extent is called a saturated state, and the amount of water vapor at this point is called the saturated water vapor amount. The amount of saturated water vapor varies depending on the temperature, and is greater at higher temperatures and less at lower temperatures.
So, if you cool the air, the moisture that was in the form of water vapor while the temperature was high will eventually saturate and turn into liquid. In other words, as the temperature drops, the amount of saturated water vapor also decreases, so if you continue to cool the air, at some point the water vapor will saturate and turn into liquid.
The temperature at this point is called the dew point temperature.
The dew point temperature varies depending on the amount of water vapor contained in the air; the more water vapor there is, the higher the dew point temperature is, and the less water vapor there is, the lower the dew point temperature is.
More specifically, when the temperature drops below the dew point, the saturated water vapor condenses and forms droplets on the surface of objects. This is the phenomenon known as condensation.
In this case, even if the air temperature starts dropping from the same starting temperature, the temperature at which condensation occurs will be lower when the amount of water vapor contained is less than when it is greater. For example, when the air temperature starts dropping in an environment of 25°C, if the air contains 50% of the saturated amount of water vapor, condensation will occur at about 14°C, whereas if the air contains only 30% of the saturated amount of water vapor, condensation will occur at about 6.5°C.

(b) Radiant air conditioner of this embodiment In the radiant air conditioner 11 of this embodiment, on the back side partitioned by the radiant panel 131, that is, on the side of the flow path 151 where the air conditioner 51 is arranged, the air is dried by the cooling operation of the air conditioner 51, and dry air circulates. This is because the air from the room R taken into the air conditioner 51 from the air intake 52 is rapidly cooled as it passes through the heat exchanger 53, and some of the water vapor contained in the air is liquefied and removed.
Therefore, even if the amount of saturated water vapor in the air passing through the conditioned air flow path 151 is reduced by being cooled by the cooling operation, the dew point temperature is lowered by drying, so condensation does not occur on the back surface of the radiant panel 131. More specifically, condensation does not occur on the back surface fiber 141B in the fabric cover 141, nor on the front surface fiber 141A wrapping around the back surface side.
On the other hand, the front surface side of the radiant panel 131 is cooled by the cooling operation, radiating and cooling the air in the room R. As a result, the cloth cover 141 located on the front surface of the radiant panel 131, i.e., the surface fibers 141A, maintains a low temperature state, so that the air in contact with the surface fibers 141A approaches the dew point temperature.
At this time, when the air in contact with the surface fibers 141A reaches the dew point temperature, the water vapor contained in the air begins to turn into liquid.

(c) Principle of Condensation Prevention In contrast, in this embodiment, the fabric cover 141 has breathability.
Therefore, the air passing through the conditioned air flow path 151 passes through the fabric cover 141 and leaks out to the front side of the surface fibers 141A exposed to the room R. As a result, a layer of dry air is formed on the front side of the surface fibers 141A.
Therefore, on the front side of the surface fibers 141A where the dry air forms a layer, the dew point temperature of the air is lower than the lowered temperature of the surface fibers 141A, so that condensation does not occur.
Based on the above principle, according to this embodiment, it is possible to prevent condensation from forming on the surface of the radiant panel 131 in various environments during cooling.

(2) Expansion of heat radiation area (a) Expansion in width direction As shown in Fig. 5(a), a flow path 151 for conditioned air is formed in the space between the rear panel 112 and the radiation panel 131 of the panel base 111. At this time, the width of the flow path 151 is determined by the opposing distance between a pair of side walls 113 provided on the panel base 111.
At this time, the distance between the pair of side walls 113 is determined by the width of the rear panel 112. The distance between the pair of side walls 113 does not extend beyond the width of the rear panel 112. Therefore, the width of the flow path 151 of the conditioned air also does not extend beyond the width of the rear panel 112.
In contrast, the present embodiment uses a hollow radiating panel 131. This radiating panel 131 expands its internal space from an opening O that contacts the air conditioner flow path 151, and forms a radiating surface RS on one surface opposite the opening O. The radiating surface RS has a horizontal projection surface that is wider than the width of the rear panel 112.
Therefore, according to this embodiment, the heat radiation area of the radiation panel 131 can be expanded beyond the flow path width of the air-conditioning air defined by the pair of side walls 113. As a result, it is possible to obtain a heat radiation efficiency greater than the actual size.

(b) Expansion to the area overlapping with the air conditioner As shown in Figure 5 (b), the hollow radiating panel 131 has a hollow area extending beyond the position of the air conditioner 51's air outlet 55 to a position where it overlaps with the air conditioner 51, and a radiating surface RS is also positioned in this area.
This allows the heat radiation area of the radiation panel 131 to be further expanded.
Moreover, the expanded range of the heat radiation area is limited to the area where the close contact member RM of the outer frame member 133a of the second frame body 135 comes into close contact with the housing 51a of the air conditioner 51 via the cloth cover 141. Since the close contact member RM is disposed directly below the heat exchanger 53 built into the air conditioner 51 in the vertical direction, the entire area up to the close contact member RM is used as the heat radiation area, and the heat radiation efficiency is improved.

(3) Prevention of Short-Cut Phenomenon As described above, due to the structure in which the hollow area of the radiant panel 131 is expanded to a position overlapping with the air conditioner 51, the conditioned air blown out from the air outlet 55 of the air conditioner 51 will flow around to the rear side of the air conditioner 51, that is, the side where the air intake 52 is provided. If the conditioned air flows around to the rear side of the air conditioner 51, the conditioned air will be taken in through the air intake 52, causing the so-called shortcut phenomenon. This reduces the operating efficiency of the air conditioner 51, so some kind of measure is necessary.
In this embodiment, the contact member RM of the outer frame member 133a of the second frame body 135 blocks the flow of conditioned air and prevents the occurrence of the shortcut phenomenon. When the radiating panel 131 is fully fixed (see FIGS. 16 to 18), the contact member RM comes into contact with the housing 51a of the air conditioner 51 via the fabric cover 141, and blocks the flow of conditioned air passing through the inside of the radiating panel 131 toward the rear side of the air conditioner 51.
Moreover, in this embodiment, when the first panel 131A is brought into a horizontal position (see FIGS. 16 and 18), the fabric cover 141 is pulled by the first frame 134 and maintained in a taut state. This brings the surface fiber 141A of the fabric cover 141 forming the radiating surface RS into close contact with the close contact member RM, and prevents conditioned air from leaking out from between the close contact member RM and the surface fiber 141A.
Therefore, according to this embodiment, it is possible to prevent a decrease in the operating efficiency of the air conditioner 51 due to the shortcut phenomenon.

(4) Effects Resulting from the Shape and Structure of the Seat The cloth cover 141 has a bag shape that houses the frame 132 .
This brings about the following effects.
(a) Enlargement of the heat radiation area One of the effects is that it becomes easier to make the radiation panel 131 hollow.
As a result, it becomes easy to expand the heat radiation area of the radiation surface RS in the width direction and to expand it to a region overlapping with the air conditioner 51.
(b) Ease of Manufacturing Another effect is that attachment to the frame 132 is easy, making it possible to facilitate the manufacturing of the radiating panel 131.
(c) Elimination of Disadvantages On the other hand, since the conditioned air passes through two fabric covers 141 on the way from the flow path 151 to the room R, the fabric cover 141 on the flow path 151 side acts as a resistance to the conditioned air heading toward the fabric cover 141 on the room R side. If the resistance is too large at this time, it will hinder the operation of generating a layer of dry conditioned air in the area of the fabric cover 141 facing the room R.
In this embodiment, therefore, an opening O is provided on the surface of cloth cover 141 facing flow path 151 for conditioned air, and a mesh cloth is provided in this opening O.
More specifically, a structure is adopted in which a fiber material on the front side exposed to the room R side (front fiber 141A) and a fiber material on the back side facing the rear panel 112 (back fiber 141B) are sewn together to form the cloth cover 141 into a bag shape. In this way, the back fiber 141B does not need to be a material that constitutes the cloth cover 141, and various materials and shapes can be freely adopted. In this embodiment, a mesh-like material is used for the back fiber 141B to reduce the resistance that the back fiber 141B provides to the conditioned air flowing from the flow path 151 toward the cloth cover 141 on the room R side.
Moreover, the stitching portion SP between the front surface fiber 141A and the back surface fiber 141B is aligned with the side wall 113. This prevents the stitching portion SP from being seen through the front surface fiber 141A when the radiation panel 131 is viewed from below.

(5) Ease of installation and removal of the radiating panel According to this embodiment, when installing or removing the radiating panel 131, the radiating panel 131 can be temporarily fixed in an inclined state. The radiating panel 131 can then be horizontally moved to a horizontal position, whereby the radiating panel 131 can be permanently fixed.
This facilitates the attachment and detachment of the radiation panel 131 .
In this embodiment, the radiating panel 131 is divided into the first panel 131A and the second panel 131B, and when temporarily and permanently fixing the radiating panel 131, attention needs to be focused only on the first panel 131A, which is more compact than the radiating panel 131. This makes it easier to attach and detach the radiating panel 131.

(6) Flexibility in Selection of Seat Materials According to this embodiment, the conditioned air blown out from the air outlet 55 of the air conditioner 51 is guided into the room R from the exhaust port 115. In other words, there is no need to intentionally guide the conditioned air into the room R through the fabric cover 141.
Therefore, the fabric cover 141 is not required to have the characteristics to allow conditioned air to pass through.
Basically, what is required of the cloth cover 141 is only breathability sufficient to allow the air passing through the conditioned air flow path 151 to leak into the room R and generate a layer of dry air on the surface side of the surface fibers 141A.
Therefore, according to this embodiment, the range of materials that can be selected for the seat can be expanded.

(7) Suppression of Deformation of Sheet According to this embodiment, the cloth cover 141 of the radiating panel 131 is disposed along the direction in which the conditioned air blown out from the air outlet 55 flows through the flow path 151. The air flowing through the flow path 151 is exhausted from the exhaust port 115, so that the internal pressure in the flow path 151 does not increase.
Therefore, when the radiant air conditioning device 11 is operating, no air flow or pressure increase occurs that would cause the cloth cover 141 of the radiant panel 131 to bend, and deformation of the cloth cover 141 can be minimized.

(8) Thermal Efficiency The panel base 111 is made of a heat insulating material, and is in a state equivalent to providing heat insulating parts to the rear panel 112 and the side walls 113.
This prevents the heat of the conditioned air flowing through the flow passage 151 from being taken away by the panel base 111, making it possible to efficiently heat or cool the fabric cover 141. As a result, it is possible to obtain a radiant air-conditioning device 11 with excellent thermal efficiency.
Moreover, since the panel base 111 itself is formed from a heat insulating material, there is no need to prepare a separate heat insulating material and attach it to the panel base 111, which reduces the parts cost and manufacturing cost of the panel base 111 and simplifies manufacturing.

(9) Appearance Features (a) Aesthetic Appearance The air conditioner 51 is stored in a recess C1 provided on one surface (ceiling surface C) of the room R, and the panel base 111 is joined to one surface of the room R. This makes the radiant air conditioner 11 look thin and small inside the room R.
Moreover, the radiant panel 131 also covers the air conditioner 51, and one open side of the bag-shaped cloth cover 141 is closed by a zipper 143, so that from the outside, the radiant air-conditioning device 11 appears to be just one radiant panel 131 arranged near the ceiling surface C. At this time, the radiant panel 131 has only the fiber cloth cover 141 exposed, so it presents a gentle appearance that is familiar to people's senses and sensibilities.
Therefore, it is possible to obtain a radiant air-conditioning device 11 with a sophisticated appearance that is not in the way or bothersome when installed inside the room R.
(b) Practicality and Beauty If we think a little deeper into why the radiant air conditioning device 11 appears to consist of just a single radiant panel 131 placed near the ceiling surface C, we realize that this is due to the following three factors.
- The radiating panel 131 is hollow because of the structure in which the frame 132 is covered by the cloth cover 141 - The horizontal projection area of the radiating panel 131 is larger than the width of the rear panel 112 - The horizontal projection area of the radiating panel 131 is larger than the combined area of the air conditioner 51 and the rear panel 112 Such a structure of the radiating panel 131 and the size relationship of the horizontal projection areas of each part are closely related to the "purpose" of expanding the heat radiation area mentioned above. In other words, the size relationship of the horizontal projection areas in which the radiating panel 131 is wider than the rear panel 112 contributes to expanding the heat radiation area of the radiating surface RS in the width direction. The size relationship of the horizontal projection areas in which the radiating panel 131 covers the air conditioner 51 contributes to expanding the heat radiation area of the radiating surface RS to the area overlapping with the air conditioner 51. And such an expansion of the heat radiation area of the radiating surface RS depends on the structure of the radiating panel 131, which is hollow in the first place.
From the above observations, it can be seen that the aesthetic appearance of the radiant air-conditioning device 11 is a combination of "beauty" and "use."

4. Modifications Various modifications and variations are possible upon implementation.

(1) Installation Location of the Radiant Air Conditioner For example, in this embodiment, the radiant air conditioner 11 is installed on the ceiling surface C, but in practice, it may be configured to be installed on a different surface of the room R, for example, on a wall surface W (see FIG. 1). In this case, if a recess is provided in the wall surface W and the air conditioner 51 is stored in this recess, it is possible to realize a flat-type radiant air conditioner 11 that appears to simply have a radiant panel 131 installed on the wall surface W, similar to this embodiment.

(2) Installation state of the radiant air conditioner Although an example has been shown in which the ceiling surface C is a folded-up ceiling and the air conditioner 51 is stored in the recess C1, this is not necessarily required, and the air conditioner 51 may be installed on a flat ceiling surface C or wall surface W. In this case, the air outlet 55 of the air conditioner 51 is likely to be separated from the ceiling surface C or wall surface W, but by installing the radiant panel unit 101 above the ceiling surface C or wall surface W, the inlet 114, which is the entrance of the flow path 151, can be made to face the air outlet 55.
The means for attaching the air conditioner 51 to the ceiling surface C is not limited to the hanging bolts exemplified above, and various means can be used. For example, various modifications are permitted, such as a fastening structure using screws, a fastening structure using hook-and-loop tape, and a press-fit structure.

(3) Arrangement of the Air Conditioner and the Rear Panel In this embodiment, the air outlet 55 of the air conditioner 51 and the rear panel 112 of the panel base 111 are arranged adjacent to each other with a gap therebetween. In practice, the rear panel 112 only needs to be attached to the ceiling surface C adjacent to the air outlet 55 of the air conditioner 51.
What is important at this time is that the inlet 114 of the panel base 111 communicates with the air outlet 55 .
The term "communication" here means that the conditioned air blown out from the air outlet 55 is guided to the inlet 114, and to that extent the air outlet 55 and the inlet 114 may be disposed apart from each other, in contact with each other, or overlapping with each other. In other words, the air conditioner 51 and the rear panel 112 may be disposed apart from each other, in contact with each other, or overlapping with each other.

(4) Structure of the Radiating Panel The radiating panel 131 is not necessarily limited to a structure in which the frame body 132 is covered with the cloth cover 141, but may be, for example, a structure in which Japanese paper is attached to the frame body 132, or a structure in which the frame body 132 is assembled from breathable boards. Radiating panels 131 of various materials and structures are acceptable as long as they are hollow and have a breathable radiating surface RS on one side and an opening O on the opposite side.
When adopting a structure in which the frame body 132 is covered with the cloth cover 141 as in the radiation panel 131 of this embodiment, various modifications and changes are permitted in the structure, shape, material, etc. of the frame body 132 and the cloth cover 141. For example, the number and arrangement positions of the rod-shaped members 133 constituting the frame body 132 are not limited to those introduced in this embodiment, and various numbers and arrangements are possible.

(5) Fixing Structure of Radiating Panel (a) Attachment Position of Slider In the present embodiment, a configuration example in which the slider 137 is attached to the second frame 135 has been exemplified. The implementation is not limited to this configuration, and the slider 137 may be provided in the connecting region between the first frame 134 and the second frame 135. For example, the slider 137 may be attached to the first frame 134. Alternatively, although the hinge 136 is used as a member connecting the first frame 134 and the second frame 135, a larger member may be used as such a connecting member, and the slider 137 may be attached to such a large connecting member.
(b) Alternative Fixing Structures In this embodiment, the radiating panel 131 is fixed to the air conditioner 51 and the panel base 111 using a pair of sliders 137, a pair of connecting pins 138, and a pair of suction plates 139, but various structures can be adopted for fixing the radiating panel 131.
For example, depending on the weight of the radiation panel 131, a fixing structure using only magnets may be adopted.
(c) First Panel The structure for fixing the first panel 131A is not limited to magnets MG, and various modifications are permitted, such as a fastening structure using screws or bolts, a fastening structure using hook-and-loop tape, a press-fit structure, and the like.

(6) Shape of the Radiating Panel In the above embodiment, a flat plate-shaped radiating panel 131 is exemplified, but various shapes are permissible in practice.
For example, as shown in Fig. 19(a), the radiating panel 131 may have an arch shape with both sides drooping when viewed from the front. In this case, the planar shape of the radiating panel 131 may be a rectangular shape as shown in Fig. 19(b) or an elliptical shape as shown in Fig. 19(c), or various other shapes are allowed.
Furthermore, the radiant panel 131 does not need to be in close contact with the ceiling surface C, and may be suspended from the ceiling surface C as shown in FIG.

(7) Side Walls In the above embodiment, the pair of side walls 113 are exemplified as rising from both side edges of the rear panel 112. However, in practice, the side walls 113 do not necessarily have to rise from the side edges, but may rise from a position closer to the center.
In addition, the wall portion realized as a pair of side walls 113 in this embodiment is allowable to have any shape as long as it rises in an enclosed shape from the rear panel 112 leaving only the inlet 114 and the outlet 115.
Furthermore, the pair of side walls 113 do not have to be integral with the rear panel 112 as long as they are interposed between the rear panel 112 and the radiating panel 131 .

(8) Discharge Port In the above embodiment, an example is shown in which the discharge port 115 is provided in the area facing the inlet 114, but various modifications and changes are permitted when implementing the present invention. For example, the discharge port 115 may be provided in a part of the side wall 113, and in this case, the discharge port 115 may be distributed in multiple places.

(9) Variations in Seat Zipper Position The position of the zipper 143 of the cloth cover 141 is not limited to the position shown in FIG. 21(a) as in the above embodiment, but various other embodiments are permissible, such as a position close to one side as shown in FIG. 21(b), a position surrounding three sides as shown in FIG. 21(c), or a V-shape as shown in FIG. 21(d).

(10) Another Configuration Example of a Radiant Air Conditioner FIG. 22 is a front view showing another configuration example of a radiant air conditioner 11.
1 to 21 and their modified examples, a side wall 113 is provided on the panel base 111, thereby securing space for the flow path 151 between the rear panel 112 and the radiant panel 131. In contrast, the radiant panel unit 101 of the radiant air conditioning device 11 shown in Figure 22 secures space for the flow path 151 by the radiant panel 131.
Therefore, the radiation panel 131 is provided with a three-dimensional frame body 132, not a flat one, to generate a space for the flow path 151 between the radiation panel 131 and the rear panel 112. More specifically, the frame body 132 is curved when viewed from the front and rear sides, and both end portions are connected and fixed to the rear panel 112. The fabric cover 141 is attached to such a frame body 132 so as to cover the room R side. The fabric cover 141 is fixed to the frame body 132 by, for example, hooking both side portions of the fabric cover 141 onto both side portions of the frame body 132. The fabric cover 141 is fixed to the frame body 132 in a stretched state.
Due to this structure, the panel base 111 does not have side walls 113 and is mainly composed of the back panel 112 .
The radiating panel unit 101 constructed in this manner has an inlet 114 on the rear side and an outlet 115 on the front side, and forms a flow path 151 for conditioned air from the inlet 114 to the outlet 115 between the rear panel 112 of the panel base 111 and the radiating panel 131.
Therefore, the same effects as those of the embodiment shown in FIGS. 1 to 21 are achieved.

(11) Others Any other modifications or variations are possible.
