Description

The present invention relates to a radiant air conditioner that performs radiant air conditioning.

Convection systems have been commonly used as air conditioners for maintaining a comfortable indoor space environment. This method blows conditioned air into the room with controlled temperature and humidity, and uses convection to condition the air.
However, the convection method tends to cause dissatisfaction in terms of comfort.
One of the reasons for this is that when air is convected, a difference in temperature distribution occurs between the top and bottom of the indoor space, and warm air tends to flow toward the ceiling, while cold air tends to stay on the floor. This is the opposite of the healthy and comfortable feeling of having a cold head and feet, so it inevitably makes you feel uncomfortable.
Another reason why people tend to feel dissatisfied is that the convective airflow directly hits the human body, a phenomenon called draft. For example, in an air-conditioned room, it is said that a wind speed of 0.5 m will lower the perceived temperature by 3°C. For this reason, when you enter an air-conditioned room from outside under the scorching sun, you may feel comfortable at first, but after your body cools down, you end up feeling colder.
Furthermore, many people feel uncomfortable when the airflow continues to directly hit their bodies.

Radiation type air conditioners improve the above-mentioned disadvantages of convection type air conditioners in that they do not apply airflow directly to the body.
As an example of such a radiant air conditioner, Patent Document 1 describes an air conditioner (which Patent Document 1 calls a "radiant air conditioning system") in which an air conditioner and a flat hollow case are attached to the ceiling surface. ) is disclosed.
The air conditioner used in this air conditioner takes in air from an indoor space and blows out conditioned air from an outlet. The radiant panel forms an air path between a moisture permeable radiant panel and a heat insulating panel that face each other. The air conditioner and the radiation panel are attached to the ceiling surface so that the air outlet faces the entrance of the air passage (see paragraphs [0025] to [0029] of Patent Document 1, and FIGS. 1 and 2).
According to the air conditioner having such a structure, the conditioned air blown out from the air outlet of the air conditioner is introduced into the air path and circulates within the air path. This controls the temperature of the radiant panel and provides radiant heating and cooling.

JP2016-217630A

Radiation type air conditioners use heat radiation from the radiant panel to cool and heat indoor space, so the radiant panel requires a certain amount of area.
On the other hand, the radiant panel must be removable.
However, considering the area of the radiant panel required for heating and cooling indoor space, it is difficult to attach and detach the radiant panel, depending on its weight.
In this regard, Patent Document 1 only states that "the lower part installed on the lower surface of the ceiling plate 11 and facing the indoor space 1 consists of a radiant panel 221" (see paragraph [0028]), and the radiant panel There is no particular disclosure regarding the attachment/detachment structure.

An object of the present invention is to facilitate the work of attaching and detaching a radiation panel.

A radiant air conditioner comprising an air conditioner and a radiant panel unit, wherein the radiant panel unit is adjacent to the air outlet of the air conditioner and extends along a ceiling surface along an arrangement direction orthogonal to the width direction of the air conditioner. a rear panel attached to the back panel, a radiant panel having ventilation that faces the back panel, and a radiant panel that faces each other and is interposed between the back panel and the radiant panel along the direction in which conditioned air is blown out from the outlet. a pair of side walls arranged, the radiant air conditioner has a pair of rails and a pair of sliders arranged on both sides of the width direction, and the pair of rails are arranged along the arrangement direction. The pair of sliders are provided on the radiation panel and are slidably placed on the rail.

According to the present invention, the installation and removal work of the radiation panel can be facilitated because it is possible to install and remove the radiation panel with the slider placed on the rail diagonally, instead of installing and removing the radiation panel horizontally. can.

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

In the present embodiment, the air conditioner 51 and the radiation panel unit 101 are oriented in the width direction (width direction) in a direction perpendicular to the plane of the paper in FIG. The vertical direction is defined as the height direction.
The width direction, depth direction, and height of the housing 51a of the air conditioner 51, the panel base 111 (back panel 112, side wall 113) and the radiation panel 131 (frame body 132, cloth cover 141) constituting the radiation panel unit 101, which will be described later. The direction also conforms to the above regulations (see FIGS. 2 to 4).
Therefore, when referring to both sides of each part, it means both sides of each part in the width direction (width direction).
In FIG. 1, the front of the air conditioner 51 is the right side, and the back is the left side.
In FIG. 1, the front side and tip side of the radiation panel unit 101 and its components are on the right side, and the rear side and rear end side are on the left side. Therefore, the leading end of the radiation panel unit 101 and its components is the right end in FIG. 1, and the rear end is the left end in FIG.

(1) Air conditioner The ceiling surface C is a folded ceiling and has a depression C1 (see also FIGS. 10 and 11). The air conditioner 51 is attached, for example, with hanging bolts so as to fit into the depression C1 (see FIG. 10).
The air conditioner 51 includes a thin housing 51a whose dimensions decrease in the order of width, depth, and height, and each part is housed inside the housing 51a.
The air conditioner 51 having such a shape takes in air from the room R from an air intake port 52 provided on the back side, and blows out conditioned air from an outlet 55 by a blower 54 via a heat exchanger 53. . A filter 56 is detachably attached to the air intake port 52.
The air conditioner 51 installed so as to fit into the recess C1 of the ceiling surface C has the air outlet 55 positioned along the edge E that forms the boundary between the ceiling surface C and the recess C1.

(2) Radiation Panel Unit The radiation panel unit 101 includes a panel base 111 and a radiation panel 131.

(a) Panel Base As shown in FIG. 2, the panel base 111 is a heat insulating member having a pair of side walls 113 raised from both sides of a rectangular flat back panel 112. For example, resin, plaster, urethane, glass wool, rock wool, etc. can be used as the material for the panel base 111.
The pair of side walls 113 are upright from both end portions in the long side direction (width direction) of the back panel 112, that is, from both side ends, and slightly wrap around in the width direction along the long sides. Therefore, due to its 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 convenience of explanation, the region on one end side of the pair of side walls 113 will be referred to as the inlet 114, the region on the other end side will be referred to as the outlet 115, and the region facing the back panel 112 will be referred to as the facing region 116. The facing area 116 is an area within a plane that includes the upper end surfaces of the pair of side walls 113.

Therefore, the panel base 111 uses the back panel 112 as a base, and is provided with a side wall 113 as a wall portion that stands up from the back panel 112 in an enclosing manner, leaving an inlet 114 and an outlet 115. The inlet 114 is installed in communication with the air outlet 55 of the air conditioner 51 with the open facing area 116 on one side facing the room R side.

A pair of stoppers 117 are provided on the panel base 111 so as to be located at the discharge port 115 . As a result, the discharge ports 115 are distributed at three locations: one wide location in the center and two narrow locations on both sides. These stoppers 117 are constituted by stopper fittings 119 fixed to the back panel 112.
The stopper fitting 119 functions as a connecting tool and is provided with a connecting groove 119a.

As shown in FIG. 1, the panel base 111 is arranged so that the inlet 114 is positioned with a gap between it and the air conditioner 51 along the edge E that forms the boundary between the ceiling surface C and the depression C1. It is attached to the ceiling surface C. The means for attaching the panel base 111 to the ceiling surface C is not limited to any type. For example, screws, hook-and-loop fasteners, adhesive tape, adhesion, or other means 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 formed of, for example, EPS. Therefore, the entire structure functions as a heat insulating material.

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

The frame body 132 is formed by connecting a plurality of rod-like members 133 and forming a rectangular shape having ribs for reinforcement and rotation prevention. A portion of the rod-shaped member 133 is used as an outer frame member 133a that is assembled into a rectangular shape that determines the outer shape of the frame body 132, and the other portion is used as a reinforcing member 133b that reinforces the outer frame. As an example, a prismatic aluminum pipe having a hollow structure is used as the rod member 133, and the frame 132 is configured by connecting these with a resin connector or screwing them together.
As another example, the rod-shaped member 133 may be molded from resin or carbon.
Such a frame 132 includes a first frame 134 and a second frame 135.
The first frame 134 is arranged in a region facing the air conditioner 51. The width of the first frame 134 is set wider than that of the air conditioner 51.
The second frame 135 is larger in both the width direction and the depth direction than the panel base 111, and the rear end side in the depth direction has a length that reaches the rear part of the lower surface of the air conditioner 51 in the depth direction. It's sato.
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 has a size that completely covers the air conditioner 51 together with the rear end of the second frame 135 in the depth direction.

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. One open side becomes an open edge 142 from which the frame 132 can be stored. A chuck 143 is attached to the open edge 142 and can be opened and closed by the chuck 143. The open edge 142 is positioned slightly inside the end of the cloth cover 141.
The cloth cover 141 is made of cloth, that is, 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 shape of the cloth cover 141 can also be seen as an endless shape when viewed as a shape that wraps around the width direction of the frame 132. This is because an endless shape with both ends open and one end closed becomes a bag shape.

The bag-shaped cloth cover 141 has a structure in which a fibrous material on the front side exposed to the room R side and a fibrous material on the back side facing the flow path 151 are sewn together. For convenience of explanation, the fiber material on the front side will be referred to as surface fiber 141A (see also FIGS. 17 and 18), and the fiber material on the back side will be referred to as back fiber 141B.
The surface fibers 141A are exposed on the indoor R side when the radiant panel 131 is installed, and determine the external appearance of the radiant air conditioner 11. Therefore, when selecting the material for the surface fibers 141A, importance is placed on the aesthetic point of view.
The material of the back surface fibers 141B is selected from the viewpoint of minimizing resistance to the air flow when the air flow blown from the air outlet 55 of the air conditioner 51 is guided to the back side of the surface fibers 141A. . From this point of view, in this embodiment, mesh cloth, that is, mesh material fibers are used as the back surface fibers 141B.
As shown in FIGS. 3 and 4, the surface fibers 141A extend to the back side facing the back panel 112, and are sewn together with the back fibers 141B on the back side. The stitched portion SP of the cloth cover 141 is positioned 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 radiation panel 131 in which the frame body 132 is covered with the cloth cover 141 is covered with the cloth cover 141 because the first frame body 134 and the second frame body 135 are rotatable around the axis passing through the hinge 136. It can be rotated freely even in the closed state. Therefore, for convenience of explanation, the part of the radiation panel 131 where the cloth cover 141 covers the first frame 134 is the first panel 131A, and the part where the cloth cover 141 covers the second frame 135 is the second panel 131B. It is called.
The first panel 131A serves as an area facing a part of the air conditioner 51.
The second panel 131B serves as an area facing the remaining part of the air conditioner 51 and the entire surface of the panel base 111.

As shown in FIG. 1, the radiant panel 131 is positioned and fixed to the facing area 116 of the panel base 111. This defines a space from the inlet 114 to the outlet 115, which becomes a flow path 151 for conditioned air.
As schematically shown in FIG. 5(a), the radiation panel 131 in which the frame body 132 is covered with the cloth cover 141 has one surface made of surface fibers 141A and the other surface made of back surface fibers 141B. It forms a hollow shape. At this time, since the back fibers 141B of the cloth cover 141 are mesh cloth, the radiation panel 131 creates a state equivalent to having an opening O on the back side. Therefore, the conditioned air flowing through the flow path 151 freely enters the inside of the radiation panel 131 from the back side fibers 141B and comes into contact with the inside of the front side fibers 141A. For this reason, the surface fiber 141A, which has air permeability to begin with, functions as a radiation surface RS.

As described above, the frame 132 of the radiation 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 wider than that of the air conditioner 51, and the width and depth of the second frame 135 are set larger than the width and depth directions of the panel base 111. There is. Therefore, the radiation panel 131 has a horizontal projected area larger than the combined area of the air conditioner 51 and the panel base 111.
At this time, as schematically shown in FIG. 5(a), since the radiation panel 131 is hollow due to the cloth cover 141 covering the frame 132, from the above-mentioned dimensional relationship, the radiation surface RS on the surface fiber 141A side is wider than the width of the back panel 112.
On the other hand, the opening O is narrower than the width of the back panel 112, which corresponds to the spacing between the pair of side walls 113. In other words, the pair of side walls 113 are interposed between the back panel 112 and the radiation panel 131 along the direction in which conditioned air is blown out from the air outlet 55 of the air conditioner 51, and can be inserted between the rear panel 112 and the radiation panel 131 without protruding through the opening O. They are facing each other. As a result, the width of the conditioned air flow path 151 is defined by the pair of side walls 113, and the conditioned air is communicated with the internal space of the radiation panel 131 without leaking the conditioned air to the outside from the opening O.

As schematically shown in FIG. 5(b), the rod-shaped member 133 of the frame body 132 is positioned in the internal space of the radiation panel 131. Among these rod-shaped members 133, an outer frame member 133a of the first frame 134 and an outer frame member 133a of the second frame 135 are positioned directly below the heat exchanger 53 built in the air conditioner 51 in the vertical direction. . The housing 51a of the air conditioner 51 has a flat bottom surface, and the frame 132 is brought into close contact with the housing 51a with a cloth cover 141 interposed therebetween.
Of the first frame 134 and second frame 135 that are in close contact with the lower surface 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 close member RM. . The rod-shaped close contact member RM is a part of the outer frame member 133a, and is in close contact with the housing 51a of the air conditioner 51 via the cloth cover 141. What is in close contact is the lower surface of the housing 51a. A structure for bringing a part of the outer frame member 133a, which becomes the close contact member RM, into close contact with the housing 51a will be described later.
Such a close contact member RM partitions the internal space of the radiation panel 131 and prevents the conditioned air from going around to the rear side of the air conditioner 51 (the side of the air intake port 52) rather than the heat exchanger 53.

(c) Structure for attaching and detaching the radiation panel to the panel base As shown in FIGS. 3, 4, and 6(a) and (b), the frame 132 has a structure for temporarily attaching and fixing the radiation panel 131. A pair of sliders 137, a pair of connecting pins 138 as connected devices, and a pair of suction plates 139 as attracted members are provided.

The pair of sliders 137 are components for temporarily fixing the radiation panel 131 in cooperation with a pair of rails 57, which will be described later.
The pair of connecting pins 138 are components for permanently fixing the radiation panel 131 in cooperation with the stopper 117 described above.
The pair of suction plates 139 are components for holding the first panel 131A of the radiation panel 131 in cooperation with the magnet MG described later.

(Temporary fixing structure of radiation panel)
As shown in FIGS. 3, 4, 6(a), and 7 to 9, the temporary fixing structure of the radiation panel 131 includes a pair of rails 57 and a pair of sliders 137.
The pair of sliders 137 are each fixed to an outer frame member 133a forming a close contact member RM of the second frame 135. The fixed positions are positions near both ends of the outer frame member 133a.
The slider 137 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 has the pin 137b located at a higher position than the outer frame member 133a. The pins 137b are arranged along the width direction of the radiation panel 131, that is, along the direction of the rotation axis of the first frame 134 and the second frame 135.
As shown in FIG. 8, a pair of rails 57 are attached to both side surfaces of the housing 51a of the air conditioner 51 at lower positions on the rear side. These rails 57 extend along the arrangement direction of the air conditioner 51 and the panel base 111, and have a stepped portion 57a. The stepped portion 57a has a lower height on the panel base 111 side and a higher height on the air conditioner 51 side.

The opposing interval 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. Therefore, it becomes 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 FIGS. 12 and 13).
The pin 137b placed on the rail 57 is slidable on the rail 57. At this time, the pin 137b climbs over the step portion 57a and changes the height of the slider 137, in other words, the height of the radiation panel 131. When the slider 137 moves from the panel base 111 side to the air conditioner 51 side, the radiation 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 radiation panel 131 is positioned at a lower position. The radiation panel 131 positioned at a high position brings the outer frame member 133a of the second frame 135, which serves as the close contact member RM, into close contact with the housing 51a of the air conditioner 51 via the cloth cover 141.

As shown in FIGS. 8 and 9, regulating pieces 57b are provided at both ends of the rail 57, respectively. These regulating pieces 57b prevent the pin 137b sliding on the rail 57 from falling off.

(Fixing structure of radiant panel)
As shown in FIGS. 2 to 4 and 6(b), the main fixing structure of the radiation panel 131 includes a pair of stoppers 117 and a pair of connecting pins 138.
A pair of connecting pins 138 are fixed to the second frame 135. The fixed position is a pair of reinforcing members 133b connected to the outer frame member 133a on the opposite side to the side connected to the first frame 134. Among these reinforcing members 133b, the connecting pin 138 is attached to a position relatively close to the outer frame member 133a.
The pair of connecting pins 138 have the form of studs that fit into the connecting grooves 119a of the pair of left and right stoppers 117 provided on the panel base 111. The connecting groove 119a is located at the discharge port 115 of the radiation panel unit 101 and opens toward the indoor R side. Therefore, the connecting pin 138 fits into the connecting groove 119a of the stopper 117 as the radiation panel 131 moves horizontally from the panel base 111 toward the air conditioner 51.
Therefore, the stopper 117 and the connecting pin 138 constitute a connecting portion CN that connects the air conditioner 51 and the panel base 111 in a detachable manner according to movement of the air conditioner 51 and the panel base 111 in the arrangement direction.

(Holding structure of first panel)
As shown in FIGS. 1, 3 to 4, and 6(a), the holding structure of the first panel 131A includes a pair of magnets MG (panel holding part) and a pair of adsorption plates 139 (adhered members). It is configured.
The pair of suction plates 139 are each fixed to two reinforcing members 133b provided on the first frame 134. The fixed position is a position slightly lower than the pin 137b of the slider 137, with the first frame 134 and the second frame 135 disposed in the same plane. These suction plates 139 position flat suction surfaces 139a horizontally with the first frame 134 standing horizontally.
A pair of magnets MG are provided on the back surface of the air conditioner 51. The installation positions are near both ends. These magnets MG are attached facing downward.
The magnet MG and the attraction plate 139 are such that when the first panel 131A is raised horizontally with the radiation panel 131 permanently fixed, the attraction surface 139a of the attraction plate 139 faces the magnet MG and is attracted by magnetic force. It is positioned so that

(Invention of cloth cover)
By providing a structure for attaching and detaching the radiation panel 131 to the panel base 111, irregularities occur in the frame 132 of the radiation panel 131. This is the location 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 each of these parts, not only would the work of attaching and removing the cloth cover 141 to and from the frame body 132 be complicated, but it would also be difficult for each of these parts to function properly. I won't be able to do it.
Therefore, the cloth cover 141 has openings for exposure at the positions of the slider 137, the connecting pin 138, and the suction plate 139, so that these parts can be exposed. The illustration of the exposure opening is omitted.

2. Installation Procedure The installation procedure of the radiant air conditioner 11 will be explained.

(1) Installation of an air conditioner First, as shown in FIG. 10, the air conditioner 51 is installed in a depression C1 provided in a ceiling surface C that is a folded ceiling.
If the depression C1 is provided in advance, this is used, and if the depression C1 is not provided, the ceiling surface C is constructed to create the depression C1.

(2) Attaching the panel base As shown in FIG. 11, the panel base 111 is attached to the ceiling surface C.
The panel base 111 is aligned and fixed to the ceiling surface C so that the introduction port 114 is positioned at the edge E that forms the boundary between the ceiling surface C and the depression C1.
At this time, the introduction port 114 of the panel base 111 is positioned along the edge E that forms the boundary between the ceiling surface C and the depression C1. As a result, the air outlet 55 of the air conditioner 51 and the inlet 114 of the panel base 111 are aligned and communicate with each other (see also FIG. 1).

(3) Attaching the radiation panel (a) Temporarily fixing First, temporarily fix the radiation panel 131.
As shown in FIG. 12, a pair of sliders 137 (see FIG. 4, etc.) provided on the radiation panel 131 are brought close to the rails 57 provided on both sides of the air conditioner 51, and as shown in FIG. The radiation panel 131 is temporarily fixed by placing it on the panel. The slider 137 is placed on the front side of the rail 57 at a low height location.
In the temporarily fixed state of the radiation panel 131, the positions of the second frame body 135 and the first frame body 134 are not restricted, and the radiation panel 131 is in a freely rotatable state.

(b) Rotation of the second panel As shown in FIG. 14, after the radiation panel 131 is temporarily fixed, the second panel 131B is rotated to make it horizontal.
At this time, the pair of sliders 137 are placed at a location where the height of the pair of rails 57 is low. The connecting pin 138 of the second panel 131B faces the stopper fitting 119 of the panel base 111 with an interval therebetween.

(c) Final fixation As shown in FIG. 15, once the second panel 131B is leveled, push it in while maintaining the same posture. That is, the radiation 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 radiation panel 131 is permanently fixed.
At this time, the slider 137 slides on the rail 57, climbs over the stepped portion 57a, and is positioned at a high position. As a result, the tip side of the radiation panel 131, that is, the end side of the second panel 131B connected to the first panel 131A is lifted and pressed against the lower surface of the housing 51a of the air conditioner 51. As a result, the outer frame member 133a, which becomes the close contact member RM of the second frame body 135, comes into close contact with the lower surface of the housing 51a via the cloth cover 141.
When the radiation panel 131 is permanently fixed, the first panel 131A rotates freely by the hinge 136 and hangs down in the vertical direction.

(d) Holding the first panel As shown in FIGS. 16 to 18, the first panel 131A is rotated and made horizontal.
Then, the attraction surface 139a of the attraction plate 139 provided on the first panel 131A is magnetically attracted to the magnet MG provided on the back surface of the air conditioner 51, and is attracted to the magnet MG via the cloth cover 141. As a result, the first panel 131A is held and kept in a horizontal state.
By keeping the first panel 131A in a horizontal state, the cloth cover 141 is pulled by the first frame 134 and kept in a tensioned state.
In this way, the installation work of the radiation panel 131 is completed.

(4) Removing the radiation panel (a) Releasing the holding of the first panel As shown in FIG. 17, the first panel 131A is rotated against the attraction force of the attraction plate 139 due to the magnetic force of the magnet MG.
Then, as shown in FIG. 15, when the user releases his or her hand, the first panel 131A rotates freely and hangs down in the vertical direction.

(b) Uncoupling the connecting portion Grip and pull the second panel 131B from the state shown in FIG. 15 to the state shown in FIG. 14. That is, the radiation 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 main fixation of the radiation panel 131 is released.
At this time, the slider 137 slides on the rail 57, climbs over the stepped portion 57a, and is positioned at a lower height position. As a result, the position of the tip end side of the radiation panel 131, that is, the end side of the second panel 131B connected to the first panel 131A is also lowered and separated from the lower surface of the housing 51a of the air conditioner 51. As a result, the state in which the outer frame member 133a serving as the close contact member RM of the second frame body 135 is brought into close contact with the lower surface of the housing 51a via the cloth cover 141 is also released, and the radiation panel 131 is brought into a temporarily fixed state.

(c) Rotation of the second panel As shown in FIG. 13, the second panel 131B is rotated using the pin 137b of the slider 137 placed on the rail 57 as a starting point to make it tilted.

(d) Falling off Grasp both ends of the second panel 131B and lift the slider 137 from the rail 57 to make it fall off.
This completes the removal work of the radiation panel 131.

3. Effects When the air conditioner 51 is operated, conditioned air is blown out from the outlet 55 and flows through the flow path 151 from the inlet 114 to the outlet 115. Then, the temperature of the radiation panel 131 is adjusted by the conditioned air. It gets warmer when heating, and cools when cooling. As a result, the room R is radiantly air-conditioned.

(1) Prevention of dew condensation During cooling, the radiant air conditioner 11 of this embodiment suppresses dew condensation on the radiant panel 131.
The reason will be explained in detail.

(a) Causes of dew condensation Moisture is contained in the air as a gas (water vapor).
The state in which air contains water vapor to the limit is called a saturated state, and the amount of water vapor at this time is called the saturated amount of water vapor. The amount of saturated water vapor varies depending on the temperature; the higher the temperature, the more it increases, and the lower the temperature, the less it decreases.
When the air is cooled, the moisture that was in the form of water vapor while the temperature was high eventually becomes saturated and changes to liquid. In other words, as the temperature decreases, the amount of saturated water vapor decreases, so if the air continues to be cooled, at some point the water vapor will become saturated and turn into liquid.
The temperature at this time is called the dew point temperature.
The dew point temperature varies depending on the amount of water vapor contained in the air, and the higher the amount of water vapor, the higher the temperature, and the lower the amount, the lower the temperature.
More specifically, when the temperature drops below the dew point, saturated water vapor condenses and forms water droplets that adhere to the surface of objects. This is a phenomenon called condensation.
At this time, even if the temperature starts from the same temperature and decreases, the temperature at which condensation occurs will be lower when the amount of water vapor contained is small than when it is large. For example, when the temperature starts to drop in an environment of 25°C, if the water vapor contains 50% of the saturated amount of water vapor, condensation will occur at about 14°C, but if it contains only 30% of the saturated water vapor, condensation will occur. The temperature is approximately 6.5°C.

(b) Radiant air conditioner of this embodiment In the radiant air conditioner 11 of this embodiment, the air conditioner is The cooling operation of 51 promotes drying of the air and allows the dry air to circulate. This is because the air in the room R taken into the air conditioner 51 from the air intake port 52 is rapidly cooled when passing through the heat exchanger 53, and some of the water vapor contained in the air is liquefied and removed. be.
Therefore, even if the saturated water vapor amount of 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 that no dew condensation occurs on the back surface of the radiation panel 131. More specifically, no dew condensation occurs on the back surface fibers 141B in the cloth cover 141 or on the surface fibers 141A that wrap around to the back surface side.
On the other hand, the surface side of the radiation panel 131 is cooled by the cooling operation, and the air in the room R is radiatively cooled. Therefore, the cloth cover 141 located on the surface of the radiation panel 131, that is, 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 tries to change to liquid.

(c) Principle of preventing dew condensation On the other hand, in this embodiment, the cloth cover 141 is breathable.
Therefore, the air passing through the conditioned air flow path 151 passes through the cloth cover 141 and leaks to the front side of the surface fibers 141A exposed to the indoor R side. As a result, dry air forms a layer on the front side of the surface fibers 141A.
Therefore, on the front side of the surface fibers 141A where dry air forms a layer, the dew point temperature of the air is lower than the reduced temperature of the surface fibers 141A, so no dew condensation occurs.
Based on the above principle, according to the present embodiment, it is possible to prevent dew condensation from forming on the surface of the radiation panel 131 in various environments during cooling.

(2) Expansion of heat radiation area (a) Expansion in the width direction As shown in FIG. Formed in space. At this time, the width of the flow path 151 is defined by the distance between the opposing sides of the 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 back panel 112. The distance between the pair of side walls 113 does not extend beyond the width of the back panel 112 . Therefore, the width of the conditioned air flow path 151 does not expand beyond the width of the back panel 112.
In contrast, in this embodiment, a hollow radiation panel 131 is used. This radiation panel 131 expands the internal space from an opening O in contact with the flow path 151 of the air conditioner, and forms a radiation surface RS on one surface opposite to the opening O. The radiation surface RS has a horizontal projection surface that is wider than the width of the back panel 112.
Therefore, according to the present embodiment, the heat radiation area of the radiation panel 131 can be expanded beyond the width of the conditioned air flow path defined by the pair of side walls 113. As a result, it is possible to obtain heat radiation efficiency greater than the actual size.

(b) Expansion to the area overlapping with the air conditioner As shown in FIG. A radiation surface RS is also arranged in this region.
Therefore, the heat radiation area of the radiation panel 131 can be further expanded.
Moreover, the expansion range of the heat radiation area is limited to the area where the close contact member RM formed by the outer frame member 133a of the second frame 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 placed directly below the heat exchanger 53 built in the air conditioner 51 in the vertical direction, the area up to the close contact member RM is entirely used as a heat radiation area, and the heat radiation efficiency is improved. It will be planned.

(3) Prevention of shortcut phenomenon As mentioned above, due to the structure in which the hollow area of the radiation panel 131 is expanded to a position where it overlaps with the air conditioner 51, the conditioned air blown out from the air outlet 55 of the air conditioner 51 is 51, that is, the side where the air intake port 52 is provided. At this time, if the conditioned air goes around to the back of the air conditioner 51, the conditioned air will be taken in from the air intake port 52, causing a so-called shortcut phenomenon. This reduces the operating efficiency of the air conditioner 51, so some kind of countermeasure is required.
In this regard, in this embodiment, the close contact member RM formed by 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 radiation panel 131 is permanently fixed (see FIGS. 16 to 18), the close contact member RM comes into close contact with the housing 51a of the air conditioner 51 via the cloth cover 141, passes through the inside of the radiation panel 131, and closes the air conditioner 51. Obstructs the flow of conditioned air toward the rear side of the unit.
Moreover, in this embodiment, when the first panel 131A is placed in a horizontal state (see FIGS. 16 and 18), the cloth cover 141 is pulled by the first frame 134 and kept in a stretched state. As a result, the surface fibers 141A of the cloth cover 141 forming the radiation surface RS come into close contact with the close member RM, and leakage of conditioned air from between the close member RM and the surface fibers 141A is also prevented.
Therefore, according to the present embodiment, it is possible to prevent the operational efficiency of the air conditioner 51 from decreasing due to the shortcut phenomenon.

(4) Effects brought about by the shape and structure of the seat The cloth cover 141 has a bag shape in which the frame 132 is housed.
This brings about the following effects.
(a) Expansion of heat radiation area One effect 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 extend it to a region overlapping with the air conditioner 51.
(b) Ease of manufacturing Another effect is that it is easy to attach to the frame 132, and the radiation panel 131 can be manufactured easily.
(c) Elimination of Disadvantages On the other hand, since the conditioned air passes through two cloth covers 141 while reaching the room R from the flow path 151, the conditioned air flows toward the cloth cover 141 on the room R side. On the other hand, the cloth cover 141 on the flow path 151 side acts as resistance. If the resistance is too large at this time, it will interfere with the operation of creating a layer of dry conditioned air in the area of the cloth cover 141 facing the room R.
Therefore, in this embodiment, an opening O is provided on the surface of the cloth cover 141 facing the conditioned air flow path 151, and a mesh cloth is provided in this opening O.
More specifically, the fabric cover 141 is sewn into a bag by employing a structure in which the front fiber material (surface fibers 141A) exposed to the indoor R side and the back fiber material (back fibers 141B) facing the back panel 112 are sewn together. I try to form it into a shape. By doing so, the back surface fibers 141B do not need to form the body of the cloth cover 141, and various materials and shapes can be freely employed. In this embodiment, by using a mesh-like material for the back fibers 141B, it is intended to reduce the resistance that the back fibers 141B give to the conditioned air flowing from the flow path 151 toward the fabric cover 141 on the indoor R side.
Furthermore, the seamed portion SP of the front fiber 141A and the back fiber 141B is aligned with the side wall 113. This can prevent the seamed portion SP from being visible through the surface fibers 141A when the radiation panel 131 is viewed from below.

(5) Facilitation of attaching and detaching the radiation panel According to the present embodiment, when attaching and detaching the radiation panel 131, it is possible to temporarily fix the radiation panel 131 in an oblique state. Thereafter, the radiation panel 131 can be permanently fixed by leveling the radiation panel 131 and moving it as it is.
Therefore, the work of attaching and detaching the radiation panel 131 can be facilitated.
At this time, in this embodiment, the radiation panel 131 is divided into a first panel 131A and a second panel 131B, and when temporarily fixing and permanently fixing the radiation panel 131, the first panel, which is more compact than the radiation panel 131, All you have to do is concentrate on 131A. Therefore, the work of attaching and detaching the radiation panel 131 can be made even easier.

(6) Degree of freedom in selecting sheet material According to the present embodiment, the conditioned air blown out from the outlet 55 of the air conditioner 51 is guided into the room R from the outlet 115. In other words, there is no need to intentionally lead the conditioned air into the room R through the cloth cover 141.
Therefore, the cloth cover 141 is not required to have characteristics that allow the conditioned air to pass through.
Basically, what is required of the cloth cover 141 is breathability that allows the air passing through the conditioned air flow path 151 to leak out to the room R side and to generate a layer of dry air on the front side of the surface fibers 141A. Only.
Therefore, according to this embodiment, the range of material selection for the sheet can be expanded.

(7) Suppression of Sheet Deformation According to this embodiment, the cloth cover 141 of the radiation panel 131 is arranged along the direction in which the conditioned air blown out from the air outlet 55 flows through the flow path 151. Since the air flowing through the flow path 151 is discharged from the outlet 115, the internal pressure within the flow path 151 does not increase.
Therefore, when the radiant air conditioner 11 is operated, 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 suppressed as much as possible.

(8) Thermal Efficiency The panel base 111 is made of a heat insulating material, and is in a state equivalent to providing a heat insulating section on the back panel 112 and side wall 113.
This prevents the heat of the conditioned air flowing through the flow path 151 from being absorbed by the panel base 111, making it possible to efficiently heat or cool the cloth cover 141. As a result, a radiant air conditioner 11 with excellent thermal efficiency can be obtained.
Moreover, since the panel base 111 itself is molded from a heat insulating material, there is no need to separately prepare a heat insulating material and attach it to the panel base 111, which reduces component costs and manufacturing costs for the panel base 111. It is possible to facilitate the

(9) Appearance Features (a) Aesthetics The air conditioner 51 is housed in a recess C1 provided on one side of the room R (ceiling surface C), and the panel base 111 is joined to one side of the room R. Thereby, the radiant air conditioner 11 can be made to look thin and small inside the room R.
Moreover, the radiant panel 131 also covers the air conditioner 51, and one side of the bag-shaped cloth cover 141 that is open is closed by the zipper 143. It looks like there are only one radiation panel 131. At this time, the radiation panel 131 is in a state where only the cloth cover 141 made of fiber material is exposed, so it shows a gentle expression that is familiar to human senses and sensibilities.
Therefore, it is possible to obtain a radiant air conditioner 11 with a sophisticated appearance that does not get in the way or become bothersome when installed in the room R.
(b) Purpose and beauty If we take a step further and consider the reason why the radiant air conditioner 11 looks like only a single radiant panel 131 placed near the ceiling C, it is due to the following three factors. I notice.
- The radiation panel 131 is hollow due to the structure in which the frame body 132 is covered by the cloth cover 141. - The horizontal projected area of the radiation panel 131 is larger than the width of the back panel 112. - The horizontal projected area of the radiation panel 131 is larger than that of the air conditioner. The structure of the radiation panel 131 and the size relationship of the horizontal projected area of each part are closely related to the above-mentioned "purpose" of expanding the heat radiation area. In other words, the size relationship in horizontal projected area in which the radiation panel 131 is wider than the rear panel 112 contributes to expanding the heat radiation area of the radiation surface RS in the width direction. The size relationship of the horizontal projected area in which the radiation panel 131 covers the air conditioner 51 contributes to expanding the heat radiation area of the radiation surface RS to a region overlapping with the air conditioner 51. Such an expansion of the heat radiation area of the radiation surface RS depends on the structure of the radiation panel 131, which is hollow in the first place.
From the above observation, it can be seen that the aesthetic appearance of the radiant air conditioner 11 is "beauty" associated with "use".

4. Modifications Various modifications and changes can be made in implementation.

(1) Installation location of the radiant air conditioner For example, in this embodiment, the radiant air conditioner 11 is installed on the ceiling C, but in implementation, it may be installed on a different surface of the room R, for example, the wall W (see FIG. 1). It may also be configured to install. In this case, if a recess is provided in the wall surface W and the air conditioner 51 is housed in this recess, it looks like the radiation panel 131 is simply installed on the wall surface W, similar to this embodiment. A flat-shaped radiant air conditioner 11 can be realized.

(2) Installation state of the radiant air conditioner In addition, an example is shown in which the ceiling surface C is a folded ceiling and the air conditioner 51 is housed in the recess C1, but this is not necessarily essential. An air conditioner 51 may also be installed. At this time, the air outlet 55 of the air conditioner 51 tends to separate from the ceiling C or wall W, but by installing the radiation panel unit 101 floating from the ceiling C or wall W, it becomes the entrance of the flow path 151. The inlet 114 can face the outlet 55.
The means for attaching the air conditioner 51 to the ceiling surface C is not limited to the above-mentioned hanging bolts, but various means can be used. For example, various modifications are allowed, such as a fastening structure using screws, a fastening structure using hook-and-loop tape, and a press-fitting structure.

(3) Arrangement of air conditioner and back panel In this embodiment, the air outlet 55 of the air conditioner 51 and the back panel 112 of the panel base 111 are arranged next to each other with a gap between them. In implementation, the back panel 112 may 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 .
"Communication" here means that the conditioned air blown out from the outlet 55 is guided to the inlet 114, and to that extent, even if the outlet 55 and the inlet 114 are arranged apart from each other, , may be arranged adjacent to each other, or may be arranged overlapping each other. That is, the air conditioner 51 and the back panel 112 may be placed apart from each other, may be placed in contact with each other, or may be placed overlapping each other.

(4) Structure of the radiant panel The radiant panel 131 is not necessarily limited to a structure in which the frame 132 is covered with a cloth cover 141, but may also be constructed by pasting Japanese paper on the frame 132 or assembled from a board with air permeability. It may be something like that. Radiation panels 131 made of various materials and structures are acceptable as long as they are hollow and have a ventilation 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 a cloth cover 141 like the radiation panel 131 of this embodiment, various deformations and changes are allowed in the structure, shape, material, etc. of each of the frame body 132 and the cloth cover 141. be done. For example, the number and arrangement positions of the rod-like members 133 that constitute the frame 132 are not limited to those introduced in this embodiment, but can be various numbers and arrangement.

(5) Fixed structure of radiation panel (a) Attachment position of slider In this embodiment, a configuration example in which the slider 137 is attached to the second frame 135 is illustrated. In implementation, the present invention is not limited to such a configuration, and the slider 137 may be provided in the connection area between the first frame 134 and the second frame 135. For example, it is also possible to attach the slider 137 to the first frame 134. Alternatively, although the hinge 136 is used as a member for connecting the first frame 134 and the second frame 135, it is possible to use a larger connecting member and attach the slider 137 to such a larger connecting member. You can do it like this.
(b) First Panel The structure for fixing the first panel 131A is not limited to the magnet MG, and various modifications are allowed, such as a fastening structure using screws or bolts, a fastening structure using hook-and-loop tape, and a press-fitting structure.

(6) Form of radiation panel In the above embodiment, a flat plate-shaped radiation panel 131 was illustrated, but various forms are acceptable in implementation.
For example, as shown in FIG. 19(a), the radiation panel 131 may have an arch shape with both sides hanging down when viewed from the front. At this time, various shapes are allowed for the planar shape of the radiation panel 131, including a rectangular shape as shown in FIG. 19(b) and an elliptical shape as shown in FIG. 19(c).
Further, the radiation 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 embodiment described above, the pair of side walls 113 are exemplified to stand up from both side edges of the back panel 112. On the other hand, in actual implementation, the side wall 113 may not necessarily rise from the side edge, but may rise from a position closer to the center.
Further, the wall portions realized as the pair of side walls 113 in this embodiment may have any form as long as they stand up from the back panel 112 in an enclosure shape leaving the inlet 114 and the outlet 115. .
Furthermore, the pair of side walls 113 do not need to be integrated with the back panel 112 as long as they are interposed between the back panel 112 and the radiation panel 131.

(8) Discharge Port In the embodiment described above, an example was shown in which the discharge port 115 was provided in the area facing the introduction port 114, but various modifications and changes are allowed in implementation. For example, the outlet 115 may be provided in a part of the side wall 113, or in this case, the outlet 115 may be distributed at a plurality of locations.

(9) Variations in the chuck position of the sheet The position of the chuck 143 of the cloth cover 141 is not limited to the position shown in FIG. Various embodiments are acceptable, such as a position closer to the center, a position surrounding three sides as shown in FIG. 21(c), or a V-shape as shown in FIG. 21(d).

(10) Others All other modifications and changes are possible.
