[Operation of air conditioner]
Next, the operation | movement operation | movement in the case of performing indoor air conditioning with this air conditioner 1 is demonstrated.
During the cooling operation, the indoor heat exchanger 22 functions as an evaporator and takes heat from the passing air. The indoor air taken into the indoor unit casing 21 from the inlet 26 by the indoor fan 23 is deprived of heat and cooled when passing through the indoor heat exchanger 22.

  As shown in FIG. 3, the cooled air passes through the connection port 27 and the air intake port 51 and is sent to the pressure generation space PS in the radiating portion 52a. When air is sent to the pressure generation space PS, a positive static pressure larger than the atmospheric pressure is generated in the pressure generation space PS. That is, a pressure greater than atmospheric pressure is generated in a direction perpendicular to the flow of air flowing parallel to the ceiling surface (see solid arrow A2). For this reason, the cooled air is pushed out from the gap between the fibers of the woven fabric of the radiating portion 52a and gently blown out into the room (see solid arrow A3).

Moreover, the radiation part 52a is cooled when the radiation part 52a contacts the cooled air. For this reason, the cold radiation by the radiation part 52a arises (refer broken line arrow A4).
As described above, in the air conditioner 1, the indoor cooling is performed by the gentle blowing from the gap between the fibers of the radiation unit 52a and the cold radiation of the radiation unit 52a.
During the heating operation, the indoor heat exchanger 22 functions as a condenser to heat the passing air. The heated air is sent to the pressure generation space PS in the radiating section 52a as in the cooling operation. The heated air is pushed out from the gap between the fibers of the woven fabric and gently blown into the room. Moreover, the radiation part 52a is heated when the radiation part 52a contacts the heated air. And thermal radiation by the radiation part 52a arises. Thus, in this air conditioner 1, room heating is performed by the gentle blowing from the fiber gap of the radiating section 52a and the thermal radiation of the radiating section 52a.

[Characteristic]
[1]
In the case of a convection type air conditioner that blows out temperature-adjusted air directly into a room, a so-called draft in which the blown air directly hits a resident or the like tends to occur. When such a draft arises, residents often feel uncomfortable. Moreover, even if indoor temperature adjustment is performed by blowing out air, the sensible temperature of residents may be deteriorated by the draft.

In the air conditioner 1, as described above, indoor air conditioning can be performed by radiation and gentle air blowing. For this reason, the discomfort by a draft can be eliminated.
[2]
In the case of a conventional convection type air conditioner, there is a possibility that a large temperature difference may occur for each place in the room. That is, a temperature difference is likely to occur between a place where the blown air is well reached and a place where the blown air is difficult to reach. If a large temperature difference occurs depending on the place, the difference in pleasantness and discomfort by the place becomes severe. In addition, a large temperature difference may occur in the indoor height direction.

  In the air conditioner 1, by increasing the surface area of the first radiation surface 54, radiation and gentle air blowing can be performed from the vicinity of the ceiling surface toward a wide range of indoor living space. For this reason, the whole room can be heated or cooled substantially uniformly. Thereby, it is possible to prevent an unpleasant temperature difference from occurring depending on the place in the room. Therefore, in this air conditioner 1, discomfort for the resident or the like can be eliminated. Moreover, even when a plurality of residents are indoors, a temperature environment that is comfortable for many residents can be generated.

Conversely, by changing the surface area of the first radiation surface 54, it is possible to partially change the indoor temperature environment. And the comfortable feeling of a resident etc. can further be improved by generating the indoor temperature environment which a resident etc. desires.
The radiation panel structure 5a is disposed in the vicinity of the ceiling surface and has a thin plate shape. For this reason, even if the surface area of the first radiating surface 54 facing the living space is relatively large, there is little risk of being in the way of residents.

In this air conditioner 1, both cooling and heating by radiation and cooling and heating by blowing are performed. For this reason, compared with the case where indoor air conditioning is performed only by blowing, the convection capability by blowing can be reduced.
[4]
In this air conditioner 1, the radiating portion 52a is formed of a woven fabric, and this woven fabric has a radiation rate of about 0.9. For this reason, even if it is a woven fabric, the indoor air conditioning by radiation can be performed sufficiently effectively.

Further, the air blown from the gaps between the fibers of the woven fabric has the same temperature as the temperature inside the radiating portion 52 a up to the outside of the first radiating surface 54. For this reason, indoor air conditioning by radiation can be performed efficiently.
[5]
Since the woven fabric has flexibility, when a pressure greater than the atmospheric pressure is generated in the pressure generation space PS, the radiating portion 52a formed of the woven fabric swells and tends to approach a cylindrical shape. In this case, the flat shape of the radiation part 52a as described above may not be maintained.

However, in the radiation panel structure 5a of the air conditioner 1, the distance between the first radiation surface 54 and the second radiation surface 55 is maintained by the shape holding member 53a. For this reason, it can suppress that the flexible 1st radiation surface 54 and the 2nd radiation surface 55 swell, and can hold | maintain a flat shape.
Further, in the radiation panel structure 5 a of the air conditioner 1, the plurality of shape holding members 53 a are provided substantially uniformly on the planar surface of the first radiation surface 54 and the second radiation surface 55. For this reason, the flat shape of the radiation part 52a can be hold | maintained more accurately.

The shape holding member 53b is a thread-like member, but may be a band-like member or a rigid rod-like member, and can exert an effect of holding the shape of the radiating portion 52a. However, in order for the radiant panel structure 5a to have an effect based on the flexibility of the woven fabric, the shape holding member 53b is desirably formed of a thread-like flexible material.
[6]
In this air conditioner 1, the radiation panel structure 5a is detachably attached to the connection port 27 of the indoor unit casing 21. For this reason, it is easy to remove the radiation panel structure 5a from the indoor unit casing 21 or to attach it again. Therefore, installation work and maintenance of the radiation panel structure 5a are easy.

Moreover, the radiation part 52a is formed with the woven fabric. For this reason, when dirt adheres to the radiation part 52a, the radiation panel structure 5a can be removed and cleaned.
Second Embodiment
[Constitution]
The side view of the radiation panel structure 5b concerning 2nd Embodiment of this invention is shown in FIG.5 (b).

  The radiant panel structure 5b includes a plurality of shape holding members 53b as in the radiant panel structure 5a according to the first embodiment. In the first embodiment, the plurality of shape holding members 53a have the same length. For this reason, as shown to Fig.5 (a), the 1st radiation surface 54 and the 2nd radiation surface 55 become substantially parallel, and the radiation part 52a is hold | maintained at the flat shape. However, in the radiation panel structure 5b according to the second embodiment, the plurality of shape holding members 53b do not have the same length, but have different lengths so that the radiation portion 52b has an arbitrary shape. ing. That is, as shown in FIG. 5B, in the side view, the length of the shape holding member 53b becomes longer as the position is closer to the center, and the length is a linear function as it proceeds from the side end to the center. Is increasing. For this reason, when air is taken into the pressure generation space PS, the first radiation surface 54 swells downward as the position is closer to the center. Then, two inclined surfaces 540 and 541 are formed on the first radiation surface 54 with the center in between. The two slopes are connected at the center of the first radiation surface 54 and are inclined downward toward the center of the first radiation surface 54. In FIG. 5, only one of the shape holding members 53b is assigned a reference numeral, and the other shape holding members 53b are omitted.

Moreover, as shown in FIG.5 (c), the curved surface which curves smoothly in the downward convex may be formed in the 1st radiation surface 54 in side view. This curved surface is curved so that the center of the first radiation surface 54 swells downward.
About another structure, it is the same as that of the air conditioner 1 concerning 1st Embodiment.
[Characteristic]
When the radiation part 52a is formed flat as shown in FIG. 5A, the radiation amount varies depending on the position of a resident or the like below the first radiation surface 54. That is, the form factor that affects the amount of radiation differs depending on whether the resident or the like is at the center of the first radiation surface 54 or at the end. Therefore, there is a difference in the amount of radiation received by the resident or the like when the resident or the like is below the center of the first radiation surface 54 and below the end. More specifically, the vicinity of the center has the largest amount of radiation, and the closer to the end, the smaller the amount of radiation.

  However, in the radiation panel structure 5b according to the present embodiment, the radiation direction can be changed by holding the radiation portion 52b in the shape as described above by the plurality of shape holding members 53b (solid arrows A5, A6). reference). Therefore, the shape factor of the radiation part 52b can be made substantially equal to an arbitrary place in the room. Thereby, even when the resident is at the center of the first radiation surface 54 and at the end, the radiation amount can be made substantially the same. Therefore, in the radiant panel structure 5b, the room temperature can be more uniformly adjusted by the plurality of shape holding members 53b.

  In addition, as shown in FIG.5 (d), you may hold | maintain the radiation part 52b in the shape where the 1st radiation surface 54 inclines. In this radiant panel structure, the shape holding member located on the left side in the side view is longer, and the length of the shape holding member increases in a linear function as it proceeds from the right side to the left side. For this reason, the 1st radiation surface 54 inclines so that the left side may fall below.

In this radiation panel structure, a substantially uniform amount of radiation is given to the right space of the indoor space below the radiation portion 52b. Therefore, for example, when the space on the right side of the indoor space is the main living area, a uniform temperature environment can be created in the surrounding space of the resident or the like. Thereby, a comfortable feeling of a resident etc. can be increased further.
In addition, the inclination angle and the curvature of the first radiation surface 54 can be adjusted in more detail by changing the length and interval of the shape holding member 53b. Therefore, the first radiating surface 54 can be shaped so as to face the direction where temperature adjustment is necessary. For this reason, radiation and blowing can be performed in an appropriate direction in accordance with the size of the room and the position of a resident. Thus, in this radiation panel structure 5b, the shape of the radiation part 52b can be hold | maintained in arbitrary shapes which can produce a comfortable temperature environment.

Furthermore, the shape of the radiation part 52b may be determined not from the adjustment of the radiation amount but from a design viewpoint. That is, by adjusting the length of the shape holding member 53b, a design shape that stimulates the aesthetics of the occupants and the like may be represented in the radiation portion 52b.
<Third Embodiment>

Specifically, a plurality of fine portions of fibers and rough portions of fibers are alternately arranged on the first radiation surface 54 (see FIG. 6). Further, the coarseness of the fibers of the second radiating surface 55 is also different for each part, like the first radiating surface 54.

About another structure, it is the same as that of the air conditioner 1 concerning 1st Embodiment.
[Characteristic]
FIG. 6 shows a side view of the radiation panel structure 5c in a state where air is sent to the radiation part 52c.
In this radiant panel structure 5c, the fiber roughness of the first radiating surface 54 and the second radiating surface 55 is different for each portion, and therefore the wind speed of the air blown from the gap between the fibers is different for each portion (solid arrow A7). , A8). For this reason, the reaction force by the difference in the wind speed of the blowing air changes with parts. Then, due to the difference in reaction force, how the first radiation surface 54 and the second radiation surface 55 sink can be changed depending on the portion. In this way, uneven patterns are expressed on the surfaces of the first radiation surface 54 and the second radiation surface 55. Thereby, a visual stimulus can be given to a resident etc. and the beauty of radiation panel structure 5c can be improved.

Can be collected on the inside. That is, since the radiation part 52a is formed with the woven fabric, it can collect an unnecessary thing with the fiber eyes of the woven fabric. For this reason, in this radiation panel structure 5a, it is possible to remove unnecessary substances from the air sent into the room and keep the room air clean.

In addition, this invention is applicable also to the air conditioner which takes in outdoor air and sends it to a radiation panel structure. In such an air conditioner, the above-mentioned unnecessary items are often included in the air. For this reason, this invention which can collect an unnecessary thing is especially effective.

About another structure, it is the same as that of the air conditioner 1 concerning 1st Embodiment.
[Characteristic]
In this radiation panel structure 5a, an unpleasant substance contained in the air passing between the fibers of the woven fabric can be removed by the effective component of the radiation part 52a. For this reason, the deodorization and sterilization of the air sent indoors can be performed, and clean air can be blown out indoors. Thereby, the comfortable feeling of the resident etc. in a room can be improved.

[Constitution]
A radiation panel structure 5d according to a sixth embodiment of the present invention is shown in FIG. This radiation panel structure 5d is detachably connected to the existing convection type air conditioner 100.
The convection type air conditioner 100 is a separate type air conditioner that is divided into an indoor unit 200 and an outdoor unit 300, and the indoor unit 200 is disposed in the vicinity of an indoor side wall or a ceiling surface. This convection type air conditioner 100 has refrigerant circuit components such as an indoor heat exchanger 204 and an outdoor heat exchanger (not shown), like the air conditioner 1 according to the first embodiment. A refrigerant circuit is configured between the outdoor unit 300 and the indoor unit 200. The indoor unit 200 includes an indoor unit casing 201, an indoor fan 203, and the like. The indoor unit casing 201 has a blowout port 202 through which the temperature-adjusted air passes. The indoor fan 203 generates a flow of air that is taken in from the room, passes through the indoor heat exchanger 204, and is blown out from the blowout port 202. The convection type air conditioner 100 adjusts the temperature of the air taken into the indoor unit 200 and blows out the temperature-adjusted air from the outlet 202 provided in the indoor unit 200. Thus, this convection type air conditioner 100 can independently cool and heat the room by blowing out the temperature-adjusted air from the outlet 202 into the room.

The radiation panel structure 5d is connected to the outlet 202 of the convection type air conditioner 100. Specifically, the air intake port 51d of the radiant panel structure 5d is connected to the air outlet 202 of the existing convection type air conditioner 100.

Therefore, an air conditioner having the same capability as the air conditioner 1 according to the first embodiment can be simply configured simply by attaching the radiation panel structure 5d. For this reason, the existing convection type air conditioner 100 can be effectively used.

  Moreover, since the existing convection type air conditioner 100 and the radiation panel structure 5d are detachable, the radiation panel structure 5d can be easily detached and attached. For this reason, maintenance such as cleaning and replacement of the radiation panel structure 5d can be easily performed. For example, by applying the present invention to a radiant panel structure that can collect unnecessary substances such as dust, viruses, and pollen, like the radiant panel structure 5a according to the fourth embodiment, the inside of the radiant panel structure Dirt maintenance can be easily performed.

<Seventh embodiment>
[Constitution]
The side view of the radiation panel structure 5e concerning 7th Embodiment of this invention is shown to Fig.8 (a). The radiation panel structure 5e includes a guide mechanism 57 (deformation part). The guide mechanism 57 is provided in the radiation part 52e, and expands / contracts the radiation part 52e along the air blowing direction (see white arrow A9). As shown in FIG. 8B, the guide mechanism 57 folds the radiating portion 52e into a bellows and expands and contracts it. Thus, the guide mechanism 57 can increase or decrease the surface areas of the first radiation surface 54 and the second radiation surface 55 by expanding and contracting the radiation portion 52e.

[Characteristic]
In the radiation panel structure 5e, the surface area of the radiation part 52e can be increased or decreased by the guide mechanism 57. For example, as shown in FIG. 8B, the guide mechanism 57 contracts the portion from the air intake 51 of the radiating portion 52e to the center, and holds the portion from the center to the tip in a flat shape. In this case, the surface area of the radiating portion 52e is about half that of the state before contraction.

  Thus, the radiation panel structure 5e can change the surface area of the 1st radiation surface 54 and the 2nd radiation surface 55 by expanding / contracting the radiation part 52e. Then, by changing the surface areas of the first radiating surface 54 and the second radiating surface 55, the amount of radiation and the amount of air blown out can be adjusted. Moreover, the range which performs air conditioning can also be adjusted.

Such expansion and contraction of the radiation part 52e may be performed manually or automatically. When the expansion and contraction is performed automatically, a drive mechanism (not shown) for driving the guide mechanism 57 is further provided. Moreover, the surface area of the radiation part 52e can also be automatically adjusted according to driving | running conditions, such as air conditioning, by controlling a drive mechanism by the control part 6. FIG.
<Eighth Embodiment>
[Constitution]
FIG. 9 shows a partial external view of an air conditioner 1f according to an eighth embodiment of the present invention. In this air conditioner 1f, the radiation panel structure 5f includes a guide mechanism 57 that expands and contracts the radiation portion 52f, similarly to the radiation panel structure 5e according to the seventh embodiment. The indoor unit casing 21f (storage section) is provided with a storage port 28 for storing the radiation panel structure 5f.

  In the air conditioner 1f, when the operation is stopped, the radiation panel structure 5f is reduced by contracting the radiation part 52f by the guide mechanism 57 as shown in FIGS. 10 (a) and 10 (b). And as shown in FIG.10 (c), the radiation panel structure 5f is accommodated in the indoor unit casing 21f through the storage port 28. As shown in FIG. Conversely, during operation of the air conditioner 1f, the stored radiation panel structure 5f is taken out, and the radiation unit 52f is extended.

  Further, as shown in FIG. 11A, the radiation panel structure 5f may be expanded and contracted by winding the radiation portion 52f into a cylindrical shape by the guide mechanism 57. The radiation part 52f is rounded into a cylindrical shape by the guide mechanism 57, whereby the radiation panel structure 5f becomes smaller. The reduced radiation panel is accommodated in the indoor unit casing 21f from the storage port 28.

Further, the radiating portion 52f may be folded into a strip shape instead of being expanded and contracted in a bellows or being rounded as described above.
About another structure, it is the same as that of the air conditioner 1 concerning 1st Embodiment.
[Characteristic]
In this air conditioner 1f, the radiation panel structure 5f can be reduced by the guide mechanism 57 and accommodated in the indoor unit casing 21f. For this reason, when the operation of the air conditioner 1f is stopped, the radiant panel structure 5f is stored in the radiating panel structure 5f so that the resident panel and the like do not get in the way. Further, during operation of the air conditioner 1f, the indoor temperature can be adjusted again by taking out the radiating panel structure 5f from the indoor unit casing 21f and extending it.

The radiation panel structure 5f is not limited to being housed in the indoor unit casing 21f, and the radiation panel structure 5f may include a housing portion that houses the radiation portion 52f. In this case, the same effect as described above can be obtained.
<Ninth Embodiment>
[Constitution]
In the air conditioner according to the ninth embodiment of the present invention, control as shown in FIG. 12 is performed in the air conditioner 1 according to the first embodiment. In the air conditioner 1, when the control unit 6 receives an operation stop command when the air conditioner 1 is performing a cooling operation, the control unit 6 performs drying control before stopping the operation of the air conditioner 1. Do. Drying control is control which suppresses generation | occurrence | production of the dew condensation in the radiation part 52a. In this drying control, the control unit 6 controls the temperature of the air sent to the pressure generation space PS of the radiating unit 52a and the indoor fan 23, and sends air having a temperature higher than the room temperature to the radiating unit 52a. Thereby, generation | occurrence | production of dew condensation can be suppressed in the radiation part 52a.

First, when the control unit 6 receives an operation stop command for the air conditioner 1 from a remote controller or the like in step S1, the process proceeds to step S2.
In step S2, the timer is started and the time T is counted. Then, the process proceeds to step S3.
In step S3, a drying operation is performed at a temperature of room temperature + α. That is, in this drying operation, air having a temperature higher than the room temperature is sent to the radiation unit 52a. Thereby, the radiation part 52a is warmed and dried.

In step S4, the value of time T is decreased, and in step S5, it is determined whether or not time T has become zero, that is, whether or not the counting has ended. If the counting has not ended, the process returns to step S3 and the drying operation is continued. When the counting is finished, the operation of the air conditioner 1 is stopped in step S6.
In addition, said time T is the drying time calculated | required by experiment.

About another structure, it is the same as that of the air conditioner 1 concerning 1st Embodiment.
[Characteristic]
When the air conditioner 1 is performing the cooling operation, the surface temperature of the radiating portion 52a is lowered by the cold air blown from the surface of the radiating portion 52a. And just after the air conditioner 1 stops the cooling operation, the surface of the radiation part 52a maintains the low temperature. For this reason, immediately after the air conditioner 1 stops the cooling operation, the surface of the radiating portion 52a comes into contact with the ambient room air having high humidity, and condensation easily occurs in the radiating portion 52a.

  In the air conditioner 1, the control unit 6 performs drying control to reduce the moisture of the radiating unit 52a. In the drying control, as described above, the control unit 6 stops the operation of the air conditioner 1 after blowing air higher than room temperature for a certain period of time before the air conditioner 1 is stopped. Accordingly, before the operation of the air conditioner 1 is stopped, the surface of the radiating unit 52a is warmed. For this reason, in this air conditioner 1, generation | occurrence | production of the dew condensation in the radiation part 52a can be prevented.

Note that the drying control is not limited to the case where the drying operation is performed only for a predetermined time as described above, and even if the time during which the drying operation is performed is determined by detecting the temperature near the outside of the radiating unit 52a. Good. A flowchart of drying control in this case is shown in FIG.
First, when the control unit 6 receives an operation stop command for the air conditioner 1 from a remote controller or the like in step S11, the process proceeds to step S12.

In step S12, a drying operation is performed at a temperature of room temperature + α. Thereby, the radiation part 52a is warmed.
In step S13, it is determined whether or not the temperature Th of the air near the outside of the radiating portion 52a is equal to or higher than room temperature + α. That is, in step S13, it is determined whether or not the temperature of the air near the outside of the radiating portion 52a is higher than the room temperature by a predetermined temperature or more. When the temperature of the air is low, the process returns to step S12 and the drying operation is continued. If the temperature of the air is sufficiently high, the operation of the air conditioner 1 is stopped in step S14.

  Moreover, it is effective to perform the drying control not only when the cooling operation is performed as described above but also when another operation is performed. For example, in the case of an air conditioner that takes in outdoor air and blows it out into the room, when the outdoor air is taken in and blown out, or when outdoor air is taken in winter By controlling the drying, it is possible to prevent the occurrence of dew condensation in the radiation part.

Furthermore, the drying control may be performed during the operation of the air conditioner 1 as well as immediately before the operation of the air conditioner 1 is stopped.
Further, the drying control is not limited to the purpose of warming the radiating portion 52a as described above, but may be intended to dry the moisture contained in the woven fabric of the radiating portion 52a. Good.

<Tenth Embodiment>
[Constitution]
In the air conditioner according to the tenth embodiment of the present invention, the control unit 6 controls the indoor fan 23 so that the air is sent to the radiation panel structure 5a with 1 / f fluctuation.

[Characteristic]
FIG. 14 shows a part of the radiation panel structure 5a when such control is performed.
In this air conditioner, air with 1 / f fluctuation is sent to the radiation unit 52a. Since the radiation part 52a is formed of a woven fabric and has flexibility, the first radiation surface 54 and the second radiation surface 55 fluctuate with a 1 / f rhythm due to the fluctuation of air. Therefore, as shown by the solid line arrows and the broken line arrows in the figure, the radiation direction and distance of radiation and the direction of blowing change with a rhythm of 1 / f. Thereby, a natural space | interval can be given to a resident etc. and a comfortable feeling can be improved. Further, since the first radiation surface 54 fluctuates, a sense of nature can be visually given to the occupants and the like. As described above, with this air conditioner, it is possible to improve the comfort of indoor residents and the like.

Further, not the 1 / f fluctuation but the fluctuation of the eigenvalue of the radiating portion 52a and the first radiating surface 54 may be given. In this case, when the radiation part 52a or the first radiation surface 54 sufficiently fluctuates, a change is given to the balloon and the like, and a visual change is also given to the resident. Thereby, a comfortable feeling of a resident etc. can be improved.
<Other embodiments>
[1]
In said embodiment, although the radiation panel structure 5a is arrange | positioned in the ceiling surface vicinity, you may arrange | position so that a radiation panel structure may follow the indoor side wall vicinity.

  Moreover, as shown in FIG. 15, the radiation part 52g used as the shape bent in the middle may be provided. For example, as shown in FIG. 15A, the radiating portion 52g may be configured by a first plane 521g parallel to the side wall and a second plane 522g extending perpendicularly from the lower end of the first plane 521g. Further, as shown in FIG. 15B, the radiating portion 52g may be configured by a third plane 523g parallel to the side wall and a fourth plane 524g extending vertically from the upper end of the third plane 523g.

May be.

As described above, the radiating portion 52g is bent in the middle, so that a temperature environment that meets the needs of residents and the like can be created. Moreover, in the radiation panel structure 5g concerning this invention, since the radiation part 52g is formed with the woven fabric, it is easy to make the radiation part 52g into the shape bent in the middle.
[2]
In the above embodiment, the radiating portion 52a has a bag-like shape that is closed except for the air intake 51. However, as shown in FIG. 16, the air intake 51 and the ceiling surface side are opened. It may be a shape. This radiation part 52h is provided with the 1st radiation surface 54 which opposes indoor living space and is arrange | positioned in the ceiling surface vicinity, and the three side surfaces 56 which connect the 1st radiation surface 54 and a ceiling surface. The first radiation surface 54 closes below the pressure generation space PS, and the three side surfaces 56 close the sides of the pressure generation space PS except for the air intake port.

16A is a side view of the radiation panel structure 5h viewed from a direction perpendicular to the air flow (solid arrow A2) in the pressure generating space PS, and FIG. 16B is a pressure generating space PS. It is a side view of the radiation panel structure 5h seen from the direction of the air flow.
Also in such a radiation panel structure 5h, by forming the pressure generation space PS between the ceiling surface and the first radiation surface 54, the same effect as described above can be obtained.

  Further, two side surfaces 56 may be provided instead of the three side surfaces 56. For example, in the radiation panel structure 5h described above, the side surface 56 perpendicular to the direction of the air flowing through the pressure generation space PS, that is, the side surface 56 positioned at the tip of the radiation portion 52h may not exist. Even in this case, the internal static pressure is generated in the direction perpendicular to the air flowing through the pressure generation space PS, and thus the same effect as described above can be obtained. Moreover, since the opposite side of the air intake 51 of the radiation part 52h is opened, air can be blown out indoors from this part. For this reason, the temperature-adjusted air can be sent far away. Therefore, the air whose temperature has been sufficiently adjusted can reach the indoor space, and a more comfortable temperature environment can be created.

[3]
In the above embodiment, the first radiation surface 54 and the second radiation surface 55 are formed flat, but in such a shape, the radiation panel structure 5a disposed in the vicinity of the ceiling surface performs illumination or the like.

For example, an opening or a cutout may be provided in a portion facing the illumination or the like. Further, when the radiant panel structure 5a is provided in the vicinity of the side wall, it may have a shape that avoids a window or the like. Thereby, it can prevent that the radiation panel structure 5a becomes obstructions, such as illumination.

In addition, since the radiation part 52a of the radiation panel structure 5a is formed with the woven fabric, it is easy to form a shape unlike a metal etc. For this reason, even a complicated shape as described above can be easily formed.

Further, from the viewpoint of preventing drafts, only the first radiation surface 54 may be formed of a woven fabric, and other portions may be other materials having rigidity. Also in this case, the draft can be prevented by the radiation from the first radiation surface 54 and the gentle blowing.

[6]
In the above embodiment, the air conditioning operation is mainly described, but the humidity-adjusted air may be sent to the radiation unit 52a or the like to perform the humidification / dehumidification operation. In addition, the cooling / heating operation and the humidifying / dehumidifying operation may be performed simultaneously. Furthermore, the outdoor air which is not temperature-adjusted etc. may be sent to the radiation part 52a, and ventilation operation may be performed.

[7]
In the above embodiment, the radiation panel structure 5a is connected to the connection port 27 of the indoor unit casing 21, but when the duct outlet from which air is blown out is provided directly on the indoor side wall or ceiling surface, etc. The radiation panel structure 5a may be connected to the duct outlet.
[8]
In the above embodiment, the first radiating surface 54, the second radiating surface 55, and the side surface 56 are not connected separately but may be integrated.

[9]
In the above embodiment, the air conditioner 1 is not limited to the separate type in which the outdoor unit 3 and the indoor unit 2a are separate from each other, and may be an integrated air conditioner.
[10]
In the above embodiment, a woven fabric having an emissivity of 0.9 is used. However, if the woven fabric has an emissivity of 0.6 or more, more desirably 0.7 or more, or 0.8 or more. Good. Furthermore, the radiation rate may be 0.6 or less depending on the required radiation capacity and application, and in this case, the indoor temperature can be adjusted.

[11]
In the air conditioner 1 according to the first embodiment, the radiating unit 52a has a rectangular shape in a plan view, but may have another shape. For example, other polygons such as a square or a hexagon or a circle may be used.
