Description

  The present invention relates to a radiation panel used for a radiation-type air conditioner.

A convection system has conventionally been generally used as an air conditioner for maintaining the environment of the indoor space comfortably. Air-conditioned air with temperature and humidity adjusted is blown into the room to perform air conditioning by convection.
However, the convective method is easily dissatisfied in terms of comfort.
One of the causes is that when the air is convected, a temperature difference between the upper and the lower is generated in the indoor space, and the warmed air tends to flow to the ceiling side, and the cooled air tends to stay on the floor surface. Because it is in good condition for health and opposite to head cold foot fever that people feel comfortable, it is felt unpleasant by all means.
Another cause of dissatisfaction is the occurrence of a so-called draft phenomenon in which the convective air flow directly strikes the human body. For example, in a room where cooling is effective, the sensational temperature is said to decrease 3 ° C. at a wind speed of 0.5 m. For this reason, if you enter the air-conditioned room from the outdoor under the scorching sun, you feel comfortable at first, but after the body cools you feel rather cold.
In addition, there are many people who feel discomfort that the air flow continues to hit the body directly.

  Therefore, conventionally, a radiation air conditioner or a radiation air conditioning system adopting a radiation method has been proposed and put into practical use. Some of the documents introduced from this point out express "radiation" as "radiation". Both have the same meaning.

Patent Document 1 proposes a radiation air conditioner in which a heat transfer pipe for circulating a refrigerant and a heat medium is disposed near a ceiling and a radiation plate is disposed on the indoor side so as to be in contact with the heat transfer pipe. (Ref. 1, paragraph [0008], see FIG. 1). It is a mechanism which performs radiation cooling and heating by controlling the temperature of a radiation plate with the refrigerant and heat medium which distribute a heat transfer pipe.
Regarding radiant cooling, Patent Document 1 states that “the cooling is comfortable just because it is comparable to the coolness of a cave, the whole room is uniformly cool, and there is no flow of unpleasant wind” (Reference 1) Paragraph [0003]).
On the other hand, it is pointed out that condensation occurs when the temperature of the radiation plate becomes lower than the dew point temperature in the air during cooling, and the problem of condensation water falling or falling is also pointed out [paragraphs [0003] to [0004] reference).
Therefore, Patent Document 1 proposes that a cloth material having excellent moisture absorption and release properties be attached to the surface of the radiation plate (see paragraph [0006] and [0008] of document 1). The idea is to absorb moisture with a cloth material when condensation occurs on the radiation plate, and to release the absorbed moisture as the ambient humidity decreases (see paragraphs [0005], [0007], and [0009] of Document 1).

However, the air conditioner described in Patent Document 1 is premised on condensation of the radiation plate. For this reason, it is also expected that only the cloth material attached to the surface of the radiation plate can not completely absorb moisture generated by condensation.
Moreover, it is easily predicted that deterioration such as stains will occur in the cloth material which repeats moisture absorption and moisture release.
In this respect, according to Patent Document 2, an air conditioner that takes in air in the indoor space and blows out conditioned air is installed on a ceiling, and an air path is formed between a moisture-permeable radiation panel and a heat insulation panel facing each other. A radiant air conditioning system has been proposed in which a hollow case is attached to a ceiling surface and an air passage is connected to an air outlet of an air conditioner (paragraphs [0025] to [0029] of Literature 2, FIGS. 1 to 2). reference). The temperature of the radiation panel is controlled by circulating the conditioned air in the air path, thereby performing radiation cooling and heating.
In such a radiation air conditioning system, condensation does not occur on the radiation panel basically.
When the temperature of the radiation panel becomes lower than the dew point temperature in the air, the water vapor contained in the air changes to the liquid phase and tries to condense, but at this time before it completely changes to the liquid phase. Maintain a state called high-gloss copic state for a while. Meanwhile, the water vapor on the front side of the radiation panel passes through the radiation panel in the high-gloss-copic state and is absorbed by the dry air on the back side because the equilibrium action is exerted with the dry air flowing on the back side of the radiation panel. It is flushed indoors. As a result, it is possible to prevent the occurrence of condensation on the radiation panel.

Unexamined-Japanese-Patent No. 05-223287 gazette JP, 2016-217630, A Unexamined-Japanese-Patent No. 2004-271171

According to the radiation air conditioning system described in Patent Document 2 , the occurrence of condensation on the radiation panel can be basically prevented. However, condensation can not be completely prevented even when used in a harsh environment such as an open window on a rainy day.
Therefore, the inventor of the present application has carried out intensive research and development toward solving the problem of completely preventing the occurrence of condensation on the radiation panel regardless of the use environment. On the way, we came to think of using a breathable material such as woven fabric as the material of the radiation panel.

  As a conventional configuration example using a woven fabric for the radiation panel, for example, a radiation air conditioning system as shown in Patent Document 3 is known. However, this system is such that the radiation panel structure formed in a flat rectangular cube shape is entirely formed of a woven fabric and is used as a pressure generation space (paragraphs [0049] to [Document 3]. ], See FIGS. Therefore, the radiation panel structure naturally retains its shape as the internal pressure rises.

  On the other hand, if it is going to form a radiation panel in the shape of one panel, the means of form retention will be needed. In this case, although it is conceivable to hold the breathable woven fabric in some form-shaped member, the woven fabric is indeterminate and freely deformed, so that manufacturing difficulties may be expected.

  It is an object of the present invention to facilitate the manufacture of a radiation panel in the form of a single panel using materials such as woven fabrics.

The radiation panel of the present invention comprises a back panel and a wall portion rising from the back panel in an encircling manner leaving an air introduction area and an air discharge area, with the open facing area on one side facing the room side. And a frame body mounted in a virtual plane including the facing area with respect to a panel base body installed by bringing the air introduction area into communication with an air spout of an air conditioner that takes in indoor air and blows out conditioned air. An endless shape stretched over the frame in a stretched state, and by being attached to the frame in a state in which the frame is accommodated, the surface side exposed to the indoor side is one surface of the frame formed on the side, to form the back surface side of the surface forming the flow path of the conditioned air to reach with the panel substrate from said air inlet region to the air discharge area in opposition side of the one surface of the frame body, the fiber material Breathable To solve the above problems by providing a sheet, a.

  According to the present invention, it is possible to form the radiation panel into a single panel only by passing the endless sheet over the frame, and to facilitate the manufacture thereof.

1. Radiant Air-Conditioning System As shown in FIG. 1, the radiant air-conditioning system 11 of the present embodiment comprises an air conditioner 51 and a radiation panel unit 101 both installed on the ceiling surface C.
(1) Air conditioner The ceiling surface C is a folded ceiling and has a recess C1 (see also FIGS. 5 and 6). The air conditioner 51 is attached so as to be fitted into the recess C1 (see FIG. 7).
The air conditioner 51 has a thin shape in which the dimensions become smaller in the order of width, depth, and height, and takes in the air in the room R from the air intake port 52 provided on the back surface. The air conditioned air is blown out from the air spout 55 by 54. A filter 56 is detachably attached to the air intake port 52.
The air conditioner 51 mounted so as to fit into the recess C1 of the ceiling surface C locates the air jet 55 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 is composed of a panel base 111 and a radiation panel 131.

(A) Panel base As shown in FIG. 2, the panel base 111 is a resin product having a shape in which a pair of side walls 113 as wall portions are raised from both side portions of a flat plate-like rear panel 112 having a rectangular shape. . The pair of side walls 113 are raised from both end portions in the long side direction of the back panel 112, and slightly wrap around in the perpendicular direction along the long side. Therefore, due to its shape, the three surfaces of the region on one end side of the pair of side walls 113 and the region on the other end side and the region facing the back panel 112 on one side are opened. For convenience of explanation, the area on one end side of the pair of side walls 113 is referred to as an air introduction area 114, the area on the other end side is referred to as an air discharge area 115, and the area facing the back panel 112 is referred to as a facing area 116. The facing area 116 is an area in a plane including the tips of the pair of side walls 113.

  Therefore, the panel base 111 has the back panel 112 as a base, and is provided with a side wall 113 as an encircling wall which leaves the air introduction area 114 and the air discharge area 115 from the back panel 112. The air introduction area 114 is communicated with the air jet port 55 of the air conditioner 51 in a state where the open facing area 116 on one side faces the room R side.

The panel base 111 is provided with three stoppers 117 located in the air discharge area 115. As a result, the air discharge area 115 is dispersed at four places, two at the wide center side and two at the narrow sides. These stoppers 117 are integrally formed on the back panel 112, and are configured by the boss 118 and the stopper fitting 119.
The bosses 118 are open to the side of the air discharge area 115 and to the side of the facing area 116.
Among the stopper fittings 119, latch grooves 119a are provided in those positioned on the left and right, and latch holes 119b are provided in the one positioned in the center.

  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 air introduction area 114 is positioned with a gap. ing. The attachment of the panel base 111 to the ceiling surface C is, for example, by screwing. In order to insert the screw 120 (see FIGS. 8 and 9), an insertion hole 121 is formed in the panel base 111.

  Such a panel base 111 is integrally formed by, for example, an EPS. Therefore, the whole functions as a heat insulating material.

(B) Radiation Panel As shown in FIG. 3 and FIG. 4, the radiation panel 131 is formed by covering a rectangular frame 132 with a bag-shaped sheet 141.

The frame 132 connects a plurality of rod-like members 133 and is formed in a rectangular shape having ribs for reinforcement and rotation prevention. As an example, a prismatic aluminum pipe having a hollow structure is used as the rod-like member 133, and the frame 132 is configured by connecting or screwing them with a resin connector.
As another example, the rod-like member 133 may be formed of resin or carbon.
Such a frame 132 is provided with a panel frame 134 and a turning frame 135.
The panel frame 134 is larger in the width direction and the depth direction than the width direction and the depth direction of the panel base 111, and the rear end side in the depth direction has a length reaching the central portion in the depth direction of the lower surface of the air conditioner 51. ing.
The folding frame 135 is connected to the rear end portion of the panel frame 134 by a hinge 136, and is rotatable relative to the panel frame 134 (see FIG. 3). The folded back frame 135 has a size that completely covers the air conditioner 51 together with the rear end in the depth direction of the panel frame 134.

The sheet 141 has a bag shape like a duvet cover. That is, the three sides are closed and one side is open. The open side is 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.
Such a sheet 141 is formed of fibers, and has breathability and stretchability.
Therefore, the width direction and the depth direction of the sheet 141 are formed to be slightly smaller than the frame 132, and when the frame 132 is stored, the stretched state is maintained.
The shape of the sheet 141 called the bag shape can also be regarded as an endless shape when viewed as a shape that wraps the width direction of the frame 132. It is because the shape which closed the one end side of the endless shape by which both ends were open | released turns into a bag shape.

The sheet 141 having a bag shape has a sewn structure of the fiber material on the front side exposed to the indoor side R and the fiber material on the back side facing the flow path 151. For convenience of explanation, the fiber material on the surface side is referred to as surface fiber 141A (also refer to FIGS. 10 and 11), and the fiber material on the back side is referred to as back surface fiber 141B.
The surface fiber 141A is exposed to the room R side when the radiation panel 131 is installed, and determines the appearance aspect of the radiation air conditioning system 11. Therefore, when selecting the material of the surface fiber 141A, an aesthetic point of view is regarded as important.
The material of the back surface fiber 141B is selected from the viewpoint of minimizing the resistance of the air flow when the air flow ejected from the air outlet 55 of the air conditioner 51 is guided to the back side of the surface fiber 141A. Ru. For example, fibers of mesh material are suitable for use as back surface fibers 141B.
As shown in FIG. 3 and FIG. 4, the front surface fibers 141A wrap around to the back surface side facing the back surface panel 112, and are sewn together with the back surface fibers 141B on the back surface side. The sheet 141 positions 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.

As shown in FIG. 1, the radiation panel 131 is positioned and fixed in the facing area 116 of the panel base 111. As a result, a space from the air introduction area to the air discharge area is defined, and this becomes the flow path 151 of the conditioned air.
As shown in FIGS. 3 and 4, the frame 132 has a pair of temporary fixing hooks 137, three latch members 138, and a pair of structures for temporarily fixing and fixing the radiation panel 131. A magnet 139 is provided. The three latch members 138 are respectively latched by the three stoppers 117 provided on the panel base 111, and those located on the left and right are in the form of studs 138a fitted in the latch grooves 119a of the stopper 117, the center The one located at is in the form of a latch pin 138 b that fits into the latch hole 119 b of the stopper 117. The latch pin 138b has a structure in which the diameter is increased by pushing an operating portion (not shown) and the diameter is reduced by pulling, and the operating state is engaged with the stopper 117 by pushing the operating portion in a fitted state in the latch hole 119b. Keep
As shown in FIG. 7, the air conditioner 51 is provided with rails 57 for temporarily fixing the radiation panel 131 on both sides thereof, and a metal plate 58 is attached to the rear end portion of the lower surface.
The pair of temporary fixing hooks 137 is provided on a hinge 136 that rotatably connects the panel frame 134 and the folding frame 135. The temporary fixing hooks 137 are fitted to rails 57 provided on both sides of the radiation panel 131 to temporarily fix the radiation panel 131 (see FIG. 9). The pair of rails 57 does not make the temporary fixing hooks 137 completely slidable, but has a structure (not shown) for temporarily fixing the temporary fixing hooks 137 with a certain amount of play.
The three latch members 138 are attached to the rod-like member 133 located at the tip of the frame 132 and fixed to the stopper 117.
The pair of magnets 139 is attached to the rod-like member 133 located at the rear end portion of the turnback frame 135, and is attracted to the metal plate 58 attached to the lower surface of the air conditioner 51 by magnetic force.
These structures, ie, a pair of temporary fixing hooks 137, three latch members 138, and all or a part of the pair of magnets 139 are cuts provided in a sheet 141 for housing the frame 132 (see FIG. Exposed to the outside through (not shown). As another example, after the frame 132 is housed in the sheet 141, all or a part of these structures may be attached to the frame 132.

2. Installation Procedure The installation procedure of the radiation air conditioning system 11 will be described.

(1) Installation of Air Conditioner First, as shown in FIG. 5, the air conditioner 51 is installed in a depression C1 provided on a ceiling surface C which is a folded ceiling.
If the depression C1 is provided in advance, it is used, and if the depression C1 is not provided, the ceiling surface C is constructed to create the depression C1.
The wiring piping hole 202 for letting the electric wiring 201 and a piping pipe (not shown) pass is opened in the inside of the hollow C1, and the electric wiring 201 is taken out.

  Next, as shown in FIG. 6, a mounting plate 211 for mounting the air conditioner 51 is attached to the recess C1. The mounting plate 211 is screwed into the recess C1.

Then, as shown in FIG. 7, the air conditioner 51 is installed on the mounting plate 211. At this time, the air jet port 55 of the air conditioner 51 is positioned with a gap from the edge E along the edge E which forms the boundary between the ceiling surface C and the recess C1.
Thus, the installation work of the air conditioner 51 is completed.

(2) Attachment of Panel Substrate As shown in FIG. 8, the panel substrate 111 is attached to the ceiling surface C.
The panel base 111 is aligned and screwed so that the air introduction area 114 is positioned at the edge E that forms the boundary between the ceiling surface C and the recess C1. That is, the screws 120 are inserted into the plurality of insertion holes 121 formed in the panel base 111 and tightened. The panel base 111 is thereby fixed to the ceiling surface C.
At this time, the air introduction area 114 of the panel base 111 is positioned along the edge E which forms the boundary between the ceiling surface C and the recess C1. As a result, the air spout 55 of the air conditioner 51 and the air introduction area 114 of the panel base 111 are aligned and in communication with each other (see also FIG. 1).

(3) Fixing of the radiation panel As shown in FIG. 9, the radiation panel 131 is temporarily fixed.
By inserting a pair of temporary fixing hooks 137 provided on the radiation panel 131 into the rails 57 of the air conditioner 51 and sliding it to the back, the radiation panel 131 is temporarily fixed with a certain amount of play.
In the radiation panel 131 in the temporarily fixed state, the position of the panel frame 134 and the folding frame 135 is not restricted because of the structure that the temporary fixing hook 137 is provided on the hinge 136, and the radiation panel 131 is rotatable. .

Next, the radiation panel 131 is fixed.
As shown in FIG. 10, the portion of the panel frame 134 in the radiation panel 131 is rotated upward. Then, the latch member 138 is aligned with the position of the stopper 117 and the radiation panel 131 is moved in the direction of the wall surface W. As a result, the stud 138a of the latch member 138 fits into the latch groove 119a of the stopper fitting 119, and the latch pin 138b fits into the latch hole 119b. Then, the latch pin 138 b is expanded in diameter by pushing an operation portion (not shown), and the latch state is maintained with the stopper fitting 119. The panel frame 134 is fixed by this.
Thereafter, as shown in FIG. 11, the fold back frame 135 of the radiation panel 131 is rotated upward. As a result, the magnet 139 is attracted to the metal plate 58 provided on the lower surface of the air conditioner 51, and the folding frame 135 is fixed.

3. Operation and Effect When the air conditioner 51 is operated, the conditioned air spouts from the air spout 55 and flows from the air introduction area 114 to the air discharge area 115 through the flow path 151. Then, the temperature of the radiation panel 131 is adjusted by the conditioned air. It is warmed at the time of heating and cooled at the time of cooling. As a result, the room R is subjected to radiation air conditioning.

(1) Prevention of Condensation During cooling, the radiation air conditioning system 11 of the present embodiment does not cause condensation on the radiation panel 131 under any environment.
The reason is explained in detail.

(A) Causes of condensation Moisture is contained in the air as a gas (water vapor).
A state in which the air contains water vapor to the limit is called a saturated state, and the amount of water vapor at this time is called the amount of saturated water vapor. The amount of saturated water vapor fluctuates depending on the temperature, and the higher the temperature is, the lower it is.
Then, as the air is cooled down, the water which has been in the form of water vapor eventually saturates and turns into liquid while the temperature is high. That is, since the amount of saturated water vapor decreases as the air temperature decreases, if the air continues to be cooled, the water vapor saturates at a certain point and changes to a liquid.
The temperature at this time is called dew point temperature.
The dew point temperature fluctuates according to 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 lower the temperature.
In a more specific phenomenon, the saturated water vapor condenses by falling below the dew point temperature, and adheres to the surface of the substance as water droplets. This is a phenomenon called condensation.
At this time, even if the temperature drops from the same temperature as the starting point, the temperature at which dew condensation occurs is lower when the contained amount of water vapor is smaller than when it is large. For example, when the temperature starts to fall in an environment of 25 ° C., dew condensation occurs at about 14 ° C. when containing 50% of the saturated water vapor, whereas dew condensation occurs when containing only 30% water vapor Is about 6.5 ° C.

(B) Radiation air conditioning system of the present embodiment In the radiation air conditioning system 11 of the present embodiment, an air conditioner is provided on the back side divided by the radiation panel 131, that is, on the side of the flow path 151 where the air conditioner 51 is disposed. The air-cooling operation of 51 promotes drying of the air, and dry air flows. 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 part of the water vapor contained in the air is liquefied and removed. is there.
Therefore, even if the amount of saturated water vapor is reduced by cooling by the cooling operation, the dew point temperature of the air passing through the flow path 151 of the conditioned air is lowered by the drying, so that the dew is not generated on the back surface of the radiation panel 131. More specifically, neither condensation occurs on the back surface fibers 141B in the sheet 141 nor on the surface fibers 141A that wrap around on the back surface side.
On the other hand, the surface side of the radiation panel 131 is cooled by the cooling operation to radiatively cool the air in the room R. Therefore, since the sheet 141 located on the surface of the radiation panel 131, that is, the surface fiber 141A maintains a low temperature state, the air in contact with the surface fiber 141A approaches the dew point temperature.
At this time, when the air in contact with the surface fiber 141A reaches the dew point temperature, the water vapor contained in the air tends to be changed to a liquid.

(C) Principle of Condensation Prevention On the other hand, in the present embodiment, the sheet 141 has air permeability.
Therefore, the air passing through the flow path 151 of the conditioned air passes through the sheet 141 and leaks to the front side of the surface fiber 141A exposed to the indoor side R. As a result, the dried air forms a layer on the front side of the surface fiber 141A.
Therefore, on the front side of the surface fiber 141A where the dried air forms a layer, dew point temperature of the air is lower than the temperature of the lowered surface fiber 141A, so condensation does not occur.
According to the above principle, according to the present embodiment, it is possible to prevent condensation on the surface of the radiation panel 131 in various environments during cooling.

(2) Degree of Freedom in Selection of Sheet Material According to the present embodiment, the conditioned air ejected from the air outlet 55 of the air conditioner 51 is led out from the air discharge area 115 to the room R. That is, it is not necessary to intentionally guide the conditioned air to the room R through the seat 141.
Therefore, the seat 141 is not required to have characteristics for passing the conditioned air.
Basically, the sheet 141 is required to have an air permeability that allows the air passing through the flow path 151 of the conditioned air to leak to the room R side and generate a dried air layer on the front side of the surface fiber 141A. It is.
Therefore, according to the present embodiment, the range of material selection of the sheet can be expanded.

(3) Suppression of Deformation of Sheet According to the present embodiment, the sheet 141 of the radiation panel 131 is disposed along the direction in which the conditioned air jetted from the air jet port 55 flows through the flow path 151. Since the air flowing through the flow path 151 is discharged from the air discharge area 115, the internal pressure in the flow path 151 does not increase.
For this reason, when the radiation air conditioning system 11 operates, the flow of air and the increase in pressure that bend the sheet 141 of the radiation panel 131 do not occur, and the deformation of the sheet 141 can be suppressed as much as possible.

(4) Operations and Effects Provided by Shape and Structure of Sheet The sheet 141 has a bag shape for housing the frame 132.
For this reason, the attachment to the frame 132 is easy, and the manufacture of the radiation panel 131 can be facilitated.
On the other hand, since the conditioned air passes through the two sheets 141 between the passage 151 and the room R, the sheet 141 on the side of the passage 151 with respect to the conditioned air directed to the sheet 141 on the room R side. Is the resistance. At this time, if the resistance is too large, the operation of generating a dry conditioned air layer in the area of the seat 141 facing the room R may be disturbed.
Therefore, in the present embodiment, a sewn structure of the fiber material (surface fiber 141A) on the surface side exposed to the indoor R side and the fiber material (back surface fiber 141B) on the back surface facing the back panel 112 is adopted. Is formed in a bag shape. By doing this, the back surface fiber 141 B does not have to be a body as the sheet 141, and it is possible to freely adopt various materials and forms. In the present embodiment, by using a mesh-like material for the back surface fiber 141B, the reduction of the resistance given by the back surface fiber 141B to the conditioned air directed from the flow path 151 to the sheet 141 on the indoor side R is achieved.
Moreover, the stitched portion SP of the front surface fiber 141A and the back surface fiber 141B is aligned with the side wall 113. As a result, when the radiation panel 131 is viewed from below, it is possible to prevent the sewn portion SP from being seen through the surface fiber 141A.

(5) Thermal Efficiency The panel base 111 is formed of a heat insulating material, and is in a state equivalent to providing a heat insulating portion on the back panel 112 and the side wall 113.
As a result, the heat of the conditioned air flowing through the flow path 151 is not absorbed by the panel base 111, and the sheet 141 can be efficiently heated or cooled. As a result, the radiation air conditioning system 11 excellent in thermal efficiency can be obtained.
In addition, since the panel substrate 111 itself is formed of a heat insulating material, there is no complication such as separately preparing a heat insulating material and attaching it to the panel substrate 111, reducing the parts cost and manufacturing cost of the panel substrate 111, and manufacturing Can be facilitated.

(6) External Features The air conditioner 51 is housed in a recess C1 provided on one surface (the ceiling surface C) of the room R, and the panel base 111 is joined to one surface of the room R. As a result, the radiation air conditioning system 11 can be made thin and small in the room R.
Moreover, since the radiation panel 131 also covers the air conditioner 51, and the opening side of the bag-shaped sheet 141 is closed by the chuck 143, the radiation air conditioning system 11 is one sheet disposed near the ceiling surface C in appearance. It looks like the form of the radiation panel 131 only. At this time, since only the sheet 141 of the fiber material is exposed, the radiation panel 131 exhibits a gentle expression familiar with human senses and sensitivities.
Therefore, it is possible to obtain the radiant air conditioning system 11 of the sophisticated appearance aspect which does not get in the way or bother when installed in the room R.

4. Various modifications and changes are possible upon implementation.

(1) Installation location of the radiation air conditioning system For example, in the present embodiment, the radiation air conditioning system 11 installed on the ceiling surface C is shown, but in the case of implementation, it is It may be configured to be installed. In this case, if a recess is provided in the wall surface W and the air conditioner 51 is accommodated in the recess, it looks as if the radiation panel 131 is installed on the wall surface W as in the present embodiment. A flat form of the radiant air conditioning system 11 can be realized.

(2) Installation state of the radiant air conditioning system The ceiling surface C is folded up to form a ceiling, and an example of storing the air conditioner 51 in the recess C1 is shown. However, this is not necessarily required. The air conditioner 51 may be installed. At this time, the air jet port 55 of the air conditioner 51 is easily separated from the ceiling surface C or the wall surface W, but by installing the radiation panel unit 101 by floating from the ceiling surface C or the wall surface W, The air introduction area 114 can be made to face the air spout 55.

(3) Fixing structure of the radiation panel Further, in the present embodiment, the radiation panel is formed on the air conditioner 51 and the panel base 111 by using the pair of temporary fixing hooks 137, the three latch members 138, and the pair of magnets 139. Although it is made to fix 131, about fixation of radiation panel 131, it is possible to adopt various structures.
For example, although it depends on the weight of the radiation panel 131, a fixing structure using only a magnet may be adopted.
Alternatively, in the open area of the boss 118, it is slidable in parallel with the plane including the panel base 111 and is urged to be pushed out to the air discharge area 115 side to provide the stopper fitting 119, and further the latch mechanism ( (Not shown) may be provided. The latch mechanism latches the stopper fitting 119 by pushing it from the non-latched state, and releases the latch of the stopper fitting 119 by pushing it from the latched state. By doing this, if the stopper fitting 119 and the latch member 138 are formed so as to be fitted to each other according to the advancing and retracting of the stopper fitting 119, both are freely latched and unlatched by the pressing operation of the stopper fitting 119. be able to.

(4) The form of a radiation panel Although the flat-shaped thing was illustrated as a radiation panel 131 in the said embodiment, the thing of various forms is accept | permitted at the time of implementation.
For example, as shown in FIG. 12 (a), the radiation panel 131 may have an arched shape with both sides hanging down as viewed from the front. At this time, various shapes are permitted as the planar shape of the radiation panel 131, whether it is a rectangular shape as shown in FIG. 12 (b) or an elliptical shape as shown in FIG. 12 (c).
Further, the radiation panel 131 does not have to be in close contact with the ceiling surface C, and may be suspended from the ceiling surface C as shown in FIG.

(5) Side Walls In the above embodiment, the pair of side walls 113 is illustrated as rising from both side edges of the back panel 112. On the other hand, in implementation, the side wall 113 may not necessarily rise from the side edge but may rise from a position closer to the center.
In addition, the wall portions realized as the pair of side walls 113 in the present embodiment may be in any form as long as they stand up from the back panel 112 leaving the air introduction area 114 and the air discharge area 115 in the form of an enclosure. Be done.

(6) Air Discharge Area In the above-described embodiment, an example in which the air discharge area 115 is provided in the area facing the air introduction area 114 has been shown, but various modifications and changes are allowed in the implementation. For example, the air discharge area 115 may be provided in a part of the side wall 113, and in this case, the air discharge area 115 may be dispersed at a plurality of places.

(7) Variation of Chuck Position of Sheet The position of the chuck 143 of the sheet 141 is not only at the position as shown in FIG. 14 (a) as in the above embodiment, but also at one side as shown in FIG. Various embodiments are permitted such as a close position, a position surrounding three sides as shown in FIG. 14 (c), or a V shape as shown in FIG. 14 (d).
