Description

  The present invention relates to an air conditioner.

Air conditioners equipped with blowout ducts are often used for indoor air conditioning. In this air conditioner, warm air is guided by the blowout duct and blown into the room to heat the room. However, since warm air at the time of heating tends to stay above the room, it is difficult to sufficiently warm the feet of residents in the room. Therefore, conventionally, an air conditioner including a blow-out duct (hot air derivative) formed downward from a hot air generator provided on the upper side wall of the room has been devised and disclosed. (See Patent Document 1). In this air conditioner, a large number of small holes are provided in front of the blowing duct, and warm air passing through the inside of the blowing duct is blown out from the small holes of the blowing duct toward the indoor living space. According to such a conventional air conditioner, warm air can be sent to the indoor floor, and part of the warm air flows into the room from the small hole in the front. For this reason, the whole room is warmed well and comfortable heating is performed.
Japanese Utility Model Publication No. 2-100187

  However, even with the conventional air conditioner as described above, there is a case where cold air stays in the vicinity of the floor surface and the heating at the foot is not sufficient. That is, in the winter when the outside air temperature is low, cold air is likely to be generated near the indoor window. For example, there are cases where a window is cooled by outside air and heat exchange is performed with room air, or cold outside air enters from a gap between windows. In such a case, even with the conventional air conditioner, the cool air generated from the windows stays on the floor surface, so that the feet of the residents and the like are cooled, making it difficult to perform comfortable heating.

  The subject of this invention is providing the air conditioner which can relieve the cool air which arises from an indoor window, and can perform comfortable heating at the time of heating.

  The air conditioner according to claim 1 includes a radiation unit and a blower unit. A radiation part is extended in the substantially vertical direction along the window near the indoor window, has an internal space through which warm first air flows, and heats the room by radiation. A ventilation part sends 1st air to the internal space of a radiation part. Moreover, the radiation part is formed of a fiber material having at least a predetermined emissivity, and has a plurality of convex parts on the surface. The plurality of convex portions are formed of the above-described fiber material, and extend in a substantially vertical direction and are arranged in parallel at a predetermined interval.

  An air conditioner according to a second aspect is the air conditioner according to the first aspect, wherein the convex portions are provided on both the window side and the indoor side of the radiation portion.

  In the air conditioner according to the first aspect, the air in the space between the convex portions is warmed by the first air flowing through the internal space. Then, the flow of the air which raises along the space between convex parts arises by a chimney effect. And the cool air staying in the lower part of the room is lifted by this air flow. For this reason, the cool air staying in the lower part of the room is reduced. Thereby, in this air conditioner, the cool air which arises from a window can be eased and comfortable heating can be performed. Moreover, in this air conditioner, at least a part of the radiation part and the convex part are formed of a fiber-based material having a predetermined radiation rate. For this reason, radiation arises in a radiation part because a radiation part is warmed by the air which flows through the internal space of a radiation part. Moreover, warm 1st air blows off gently from the clearance gap between the fibers of a radiation part by the internal pressure of the 1st air which flows through internal space. Thereby, in this air conditioner, indoor heating can be performed by both radiation and gentle air blowing. Therefore, more comfortable heating with reduced discomfort due to the draft can be performed.

  In the air conditioner according to the second aspect, an air flow rising along the space between the convex portion and the convex portion is generated on both the window side and the indoor side of the radiating portion. And the cool air staying in the lower part of the room is lifted by this air flow. For this reason, the cool air staying in the lower part of the room is reduced. Thereby, in this air conditioner, the cool air which arises from a window can be eased and comfortable heating can be performed.

<First Reference Example>
[overall structure]
An air conditioner 1a according to a first reference example of the present invention is shown in FIG. This air conditioner 1a shares many configurations with an air conditioner 1c according to an embodiment of the present invention described later, and the configuration will be described below for reference.

  The air conditioner 1a is an air conditioner that performs air conditioning in a room R of a general household, and includes an indoor unit 2, an outdoor unit 3, and a radiation panel assembly 5a. In the room R, a floor surface FL and a ceiling surface CL are provided, and a window WD is provided perpendicular to the floor surface FL. The air conditioner 1a can perform air conditioning of the room R, such as cooling and heating, by radiation and temperature-controlled air blowing.

  The compressor 31, the electric valve 33, the four-way switching valve 32, the outdoor heat exchanger, and the like constitute a refrigerant circuit together with an indoor heat exchanger described later. The outdoor fan is rotationally driven by the outdoor fan motor 34 and generates an air flow through the outdoor heat exchanger. The outdoor unit temperature sensor 35 includes various temperature sensors that detect the temperature of the outdoor heat exchanger and the temperature of outdoor air.

  As shown in FIG. 1, the indoor unit 2 is disposed on a side wall near the ceiling surface CL of the room R, and includes an indoor unit casing 21, an indoor heat exchanger 22, a first indoor fan 23, and a first indoor fan motor 24 (FIG. 2), an indoor unit temperature sensor 25 (see FIG. 2), and the like.

  The indoor unit casing 21 houses the indoor heat exchanger 22, the first indoor fan 23, and the like, and includes a suction port 26, a connection port 27, and the like. The suction port 26 is an opening through which air taken from the room R into the indoor unit casing 21 passes. The connection port 27 is an opening through which air sent to the radiation panel assembly 5a through the indoor heat exchanger 22 in the indoor unit casing 21 passes, and is connected to an air intake port 51a of the radiation panel assembly 5a described later. The

  The indoor heat exchanger 22 is connected to the outdoor heat exchanger, the compressor 31 and the like through the refrigerant pipe 4. The indoor heat exchanger 22 adjusts the temperature of the air by exchanging heat with the passing air.

  The first indoor fan 23 is rotationally driven by a first indoor fan motor 24 to generate a harmonized air flow. The harmonized air flow is an air flow taken from the room R and sent to the radiation panel assembly 5a. The conditioned air is taken into the interior of the indoor unit casing 21 from the suction port 26, passes through the indoor heat exchanger 22, the connection port 27, and the air intake port 51a, and is a pressure generation space PS inside the radiation panel assembly 5a. (See FIG. 3).

  The indoor unit temperature sensor 25 includes various temperature sensors that detect the temperature of the indoor heat exchanger, the temperature of indoor air, and the like.

  The radiant panel assembly 5a has a flat outer shape, and extends from the vicinity of the ceiling surface CL to the vicinity of the floor surface FL along the window WD of the room R in the vertical direction. The radiation panel assembly 5a performs air conditioning such as cooling and heating by radiation using the temperature of the air whose temperature has been adjusted by the indoor unit 2 and blowing out the temperature of the air. The configuration of the radiation panel assembly 5a will be described in detail later.

  The air conditioner 1 a includes a control unit 6. The control unit 6 is provided separately for the outdoor unit 3 and the indoor unit 2, and controls the operation of the air conditioner 1a. As shown in FIG. 2, the control unit 6 includes a compressor 31, a four-way switching valve 32, an electric valve 33, an outdoor fan motor 34, an outdoor unit temperature sensor 35, a first indoor fan motor 24, an indoor unit temperature sensor 25, and the like. Connected with the components. When receiving an operation command from the remote controller 70, the control unit 6 controls each component to control the operation of the air conditioner 1a.

[Configuration of radiation panel assembly]
FIG. 3 shows an external view of the radiation panel assembly 5a.

  The radiation panel assembly 5a has a thin flat outer shape, and has a planar shape. The radiation panel assembly 5a is disposed in the vicinity of the window WD substantially parallel to the window WD. The radiation panel assembly 5a includes a radiation panel body 7a and a partition member 9a.

<Radiation panel body>
The radiant panel body 7a extends in the vertical direction along the window WD in the vicinity of the window WD of the room R, and performs air conditioning of the room R by radiation and air blowing. The radiant panel main body 7a extends from the vicinity of the ceiling surface CL where the indoor unit 2 is provided to the vicinity of the floor surface FL, and can perform heating or cooling widely in the vertical direction of the room R. The radiant panel body 7a has an air inlet 51a, a first surface 54a, a second surface 55a, two side surfaces 56a, and a lower surface 57a, and has a thin flat plate shape. The radiation panel main body 7a includes a pressure generation space PS in which a pressure greater than atmospheric pressure is generated by air. The air conditioned by the indoor unit 2 passes through the pressure generation space PS, and the conditioned air blows out from the surface of the radiation panel body 7a by the internal pressure generated in the pressure generation space PS.

  The air intake port 51a is a portion for taking in air whose temperature has been adjusted, and is an opening provided in the upper surface portion of the radiation panel body 7a. The air intake 51a is detachably connected to the connection port 27 of the indoor unit casing 21, and the air (see the white arrow A1) sent by the first indoor fan 23 passes therethrough. In addition, the air intake 51a may be configured to be connectable to the outlet of an existing convection type air conditioner. Furthermore, the air intake 51a and the air outlet of the convection type air conditioner may be detachable.

  The first surface 54a has a rectangular thin sheet shape and closes the side of the pressure generation space PS. The first surface 54a is located on the opposite side of the room R from the window WD and is disposed substantially parallel to the window WD. The first surface 54a is formed of a woven fabric having a radiation rate of about 0.9. Therefore, when the temperature of the first surface 54a is adjusted by the air flowing through the pressure generation space PS, heat radiation or cold radiation is radiated from the first surface 54a toward the living space in the room R. Further, the conditioned air is blown out from the gap between the fibers of the first surface 54a to the living space in the room R by the internal pressure generated in the pressure generating space PS.

  The second surface 55a has the same shape as the first surface 54a, and is formed of the same woven fabric as the first surface 54a. The second surface 55a faces the first surface 54a across the pressure generation space PS, and closes the side of the pressure generation space PS. The second surface 55a is disposed substantially parallel to the window WD on the window WD side. Therefore, the conditioned air is blown out from the fiber gap of the second radiation surface 55a toward the window WD by the internal pressure generated in the pressure generation space PS. Further, the temperature of the second radiation surface 55a is adjusted by the air in the pressure generation space PS, so that heat radiation or cold radiation is generated toward the window WD side.

  The two side surfaces 56a have an elongated rectangular shape and close the sides of the pressure generation space PS. The lower surface 57a also has an elongated rectangular shape, and closes the lower portion of the pressure generation space PS. The two side surfaces 56a and the lower surface 57a are formed of the same woven fabric as that of the first surface 54a.

  As described above, the radiation panel body 7a has a bag-like shape that is closed except for the air intake port 51a.

<Partition member>
The partition member 9a partitions the pressure generation space PS into a plurality of rooms through which conditioned air passes. The partition member 9a is disposed in parallel to the air flow direction (see the white arrow A1) in the pressure generation space PS, and one end is fixed to the first surface 54a and the other end is fixed to the second surface 55a. For this reason, the partition member 9a can keep the distance between the first surface 54a and the second surface 55a constant. Therefore, the partition member 9a can suppress the expansion of the radiation panel body 7a when a pressure larger than the atmospheric pressure is generated in the pressure generation space PS. That is, the partition member 9a can maintain the outer shape of the radiation panel assembly 5a in a flat plate shape by maintaining a constant distance between flat plate-shaped opposing planes.

[Operation of air conditioner]
<Heating operation>
Next, the operation in the case where the air conditioning of the room R is performed by the air conditioner 1a will be described.

  During the heating operation, the indoor heat exchanger 22 functions as a condenser to heat the passing air. As shown in FIG. 4, warmed air (hereinafter referred to as “first air”) is sent to the pressure generating space PS in the radiation panel body 7a through the connection port 27 and the air intake port 51a ( (See solid arrow A1). When the first 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 the atmospheric pressure is generated in a direction perpendicular to the flow of air flowing in parallel with the window WD (see solid arrow A1). For this reason, warm 1st air is extruded from the gap | interval of the fiber of the woven fabric of the radiation panel main body 7a, and is gently blown out to the room | chamber interior R (refer solid line arrow A2). In particular, the first air that blows out from the first surface 54a is blown out to the side opposite to the window WD, that is, the living space side of the room R. Moreover, the 1st air which blows off from the 2nd surface 55a is blown off to the window WD side. Moreover, the radiation panel main body 7a is heated by contacting with warm first air. For this reason, thermal radiation is generated from the radiation panel body 7a (see the broken line arrow A3). In particular, the heat radiation generated from the first surface 54a is radiated to the side opposite to the window WD, that is, the living space side of the room R. Further, the heat radiation generated from the second surface 55a is radiated to the window WD side.

  Thus, in this air conditioner 1a, the room R is heated by the gentle blowing from the gap between the fibers of the radiation panel body 7a and the thermal radiation of the radiation panel body 7a. That is, the living space is gently warmed by blowing warm first air from the first surface 54a of the radiation panel body 7a and heat radiation. Further, the cold air (see solid arrows A4 and A5) generated from the window WD is relieved or removed by blowing warm first air from the second surface 55a and heat radiation.

<Cooling operation>
During the cooling operation, the indoor heat exchanger 22 functions as an evaporator and takes heat from the passing air. The air in the room R taken into the indoor unit casing 21 from the suction port 26 by the first indoor fan 23 is deprived of heat and cooled when passing through the indoor heat exchanger 22. The cooled air passes through the connection port 27 and the air intake port 51a and is sent to the pressure generation space PS in the radiant panel body 7a. When the air is sent to the pressure generation space PS, the cooled air is pushed out from the gap between the fibers of the woven fabric of the radiation panel body 7a and gently blown out into the room R. Moreover, the radiation panel main body 7a is cooled by contacting with the cooled air. For this reason, cold radiation is generated from the radiation panel body 7a. As described above, in the air conditioner 1a, the room R is cooled by the gentle blowing from the gap between the fibers of the radiation panel body 7a and the cold radiation of the radiation panel body 7a.

[Characteristic]
(1)
Conventionally, blowout ducts often used in food factories or the like are mainly assumed for cooling operation, and heating operation is not considered much. Therefore, in the blowout duct arranged near the ceiling surface like the conventional blowout duct, the cool air falls from the ceiling surface at the time of cooling, so that a comfortable environment of head cold foot heat is realized. However, at the time of heating, warm air is light air, so it is difficult to reach the floor. Therefore, a large wind speed is required to allow warm air to reach the floor surface. However, when warm air is blown out toward the floor surface at such a high wind speed, the resident or the like easily feels uncomfortable feeling when the warm air directly hits the floor. In addition, when warm air is blown out at a low wind speed, the vicinity of the floor surface is difficult to warm and it is difficult to realize a comfortable environment.

  In particular, in ordinary households, in the heating season, cold air is generated from the vicinity of the window WD in the room R by heat exchange with the window WD cooled by outside air (see solid arrow A4 in FIG. 4). In addition, cold air is generated from the vicinity of the window WD by the draft air from the window WD (see the solid line arrow A5 in FIG. 4), and such cold air descends along the window WD and stays near the floor surface FL. If cold air stays in the vicinity of the floor surface FL, the feet become cold and the residents are likely to feel uncomfortable.

  In the air conditioner 1a, the radiation panel assembly 5a is disposed in front of the window WD perpendicular to the floor surface FL. And at the time of heating, the cool air which arises from the window WD vicinity is relieve | moderated or removed by the blowing of warm 1st air and the thermal radiation from the 2nd surface 55a of the radiation panel main body 7a. For this reason, at the time of heating, the cool air of the floor surface FL is reduced and the cold of the feet is relieved.

  Moreover, in this air conditioner 1a, the living space is gently warmed by blowing the first air from the first surface 54a and the heat radiation. For this reason, it is suppressed that the wind from the air conditioner 1a hits a resident etc., and the discomfort by a draft reduces.

  Furthermore, in this air conditioner 1a, since the wind at the time of heating is reduced, dust such as the floor surface FL is less likely to rise. For this reason, the contamination of the indoor air by dust can be reduced during heating.

  Thus, in this air conditioner 1a, it is possible to perform comfortable heating with less discomfort to residents and the like.

(2)
In winter when the temperature of the outside air is low, condensation may occur in the window WD due to the window WD being cooled by the outside air.

  In this air conditioner 1a, warm first air is blown out from the second surface 55a of the radiation panel body 7a to the window WD side. For this reason, the window WD is warmed by the first air, and the occurrence of condensation on the window WD can be prevented.

(3)
When the radiant panel body 7a is formed of a flexible material such as a woven cloth, the radiant panel body 7a is easily expanded by the internal pressure of the first air passing through the pressure generating space PS. Is difficult to maintain.

  However, in this radiation panel assembly 5a, expansion of the outer shape of the radiation panel body 7a is suppressed by the partition member 9a. For this reason, in this radiation panel assembly 5a, the external shape of the radiation panel main body 7a can be maintained.

(4)
As for the effect of alleviating the cool air generated from the window WD and preventing the occurrence of condensation in the window WD, it is sufficient that the warm first air blows out from at least the second surface 55a, and the first is not necessarily the first from the other part of the radiant panel body 7a. Air does not have to blow out.

  Further, as shown in FIG. 5, a blowout port 58 may be provided in the vicinity of the lower end of the second surface 55a of the radiant panel body 7a in order to alleviate the cool air generated from the window WD and prevent the formation of condensation in the window WD. . The outlet 58 is an opening through which the first air blown toward the window WD passes. Even when the warm first air is blown out from the blowout port 58, it is possible to suppress the cool air generated from the window WD from staying on the floor surface FL (see the white arrow A6). In order to alleviate cold air and prevent the occurrence of condensation, it is more effective to use the blowout from the blowout port 58 and the blowout from the second surface 55a, but only the blowout from the blowout port 58 is effective. May be performed.

<Second Reference Example>
[Constitution]
An air conditioner 1b according to a second reference example of the present invention is shown in FIG.

  In the air conditioner 1b, the indoor unit 2 is provided with an indoor unit outlet 28. The indoor unit outlet 28 is provided between the connection port 27 and the back surface of the indoor unit 2. The indoor unit outlet 28 is an opening through which the air sent between the radiation panel assembly 5b and the window WD passes through the indoor heat exchanger 22 in the indoor unit casing 21.

  During heating, the indoor unit 2 sends warm first air to the pressure generating space PS of the radiation panel body 7b and blows warm second air from the indoor unit outlet 28 toward the floor surface FL. The second air is taken in from the room R and sent between the radiation panel assembly 5b and the window WD. That is, the second air is taken into the interior of the indoor unit casing 21 through the suction port 26, passes between the indoor heat exchanger 22, the indoor unit outlet 28, the radiation panel assembly 5 b and the window WD, to the floor surface. It reaches near the FL.

  About another structure, it is the same as that of the air conditioner 1a concerning a 1st reference example.

[Characteristic]
(1)
In the air conditioner 1b, the second air warmed by the indoor heat exchanger 22 is blown out from the indoor unit outlet 28 of the indoor unit 2. The blown-out second air passes between the radiation panel body 7b and the window WD along the second surface 55b of the radiation panel body 7b and reaches the vicinity of the floor surface FL (see solid arrow A7).

  In this air conditioner 1b, the space between the radiation panel assembly 5b and the window WD is used as a ventilation path, and the warm second air passes between the radiation panel assembly 5b and the window WD to the floor surface FL. And can be reached easily. For this reason, the cool air (see solid arrows A4 and A5) generated from the window WD is relaxed or removed by the second air. For this reason, it is suppressed that cold air stays in the floor surface FL vicinity.

  Moreover, since 2nd air passes between the radiation panel main body 7b and the window WD, it is reduced that the wind by the blowing of 2nd air hits a resident etc. directly. Therefore, in this air conditioner 1b, discomfort due to the draft can be reduced.

  Furthermore, in this air conditioner 1b, warm second air can reach the floor surface FL at a lower wind speed than an air conditioner that blows warm air directly from the vicinity of the ceiling surface CL toward the floor surface FL. Can do. Therefore, in this air conditioner 1b, discomfort due to the draft can be further reduced.

  As described above, this air conditioner 1b can perform more comfortable heating.

(2)
In the air conditioner 1b, the vicinity of the window WD is heated by the second air, so that dew condensation on the window WD can be prevented in the same manner as the air conditioner 1a according to the first reference example.

(3)
Note that the above effect can be exhibited more significantly by using the first air blowing from the second surface 55b and the radiation from the second surface 55b together with the second air blowing. The effects described above can be achieved only by blowing.

<Embodiment of the present invention>
[Constitution]
The radiation panel assembly 5c with which the air conditioner 1c (refer FIG.8 (b)) concerning one Embodiment of this invention is provided is shown to Fig.7 (a) and FIG.7 (b). In addition, FIG.7 (b) is the BB cross section in Fig.7 (a).

  The radiation panel assembly 5 c has a plurality of convex portions 59. A plurality of convex portions 59 are provided on each of the first surface 54c and the second surface 55c. The convex portion 59 provided on the first surface 54c protrudes from the first surface 54c to the opposite side of the window WD. The convex portion 59 provided on the second surface 55c protrudes from the second surface 55c to the window WD side. Moreover, the convex part 59 is extended in the substantially perpendicular direction from the lower end of the radiation panel assembly 5c to the upper end vicinity, and has a shape long in the perpendicular direction. The convex portions 59 are arranged in parallel at a predetermined interval. Accordingly, a groove-like recess 60 extending in a substantially vertical direction is formed between the protrusions 59. In addition, the convex part 59 is formed with the woven fabric similar to the 1st surface 54c and the 2nd surface 55c.

  About another structure, it is the same as that of the air conditioner 1a concerning a 1st reference example.

[Characteristic]
(1)
In the air conditioner 1c, during the heating, the convex portion 59 of the radiant panel structure 5c is heated by the warm first air, so that natural convection due to the chimney effect is generated like a radiator. This natural convection is a flow of air that rises from the vicinity of the floor surface FL through the concave portions 60 between the convex portions 59 (see the solid line arrow A8 in FIGS. 8A and 8B). For this reason, the cold air (refer to solid line arrows A4 and A5 in FIG. 8B) generated from the window WD and staying in the vicinity of the floor surface FL is sucked from the floor surface FL, warmed, and lifted to the vicinity of the ceiling CL. For this reason, the cold air generated from the window WD and staying in the vicinity of the floor surface FL is reduced or removed. Thereby, in this air conditioner 1c, comfortable heating can be performed.

  Moreover, in this air conditioner 1c, compared with the case where air blows directly into the room R, the blowing sound is small and quiet.

(2)
In addition, although the effect of performing comfortable heating appears more significantly by blowing out the first air from the second surface 55c and the heat radiation, the blowing out of the first air and the heat radiation from the second surface 55c. Even if this is not performed, the effect of relieving cold air due to the occurrence of natural convection can be achieved.

<Third reference example>
[Constitution]
FIG. 9 shows an air conditioner 1d according to a third reference example of the present invention.

  In the radiation panel assembly 5d of the air conditioner 1d, the radiation panel body 7d is formed of a transparent or translucent material. That is, the first surface 54d and the second surface 55d of the radiation panel body 7d are formed of a transparent or translucent woven fabric.

  About another structure, it is the same as that of the air conditioner 1a concerning a 1st reference example.

[Characteristic]
(1)
In general, when the radiation panel assembly covers the window WD, outdoor light may be blocked by the radiation panel assembly, and the room R may become dark. In addition, when performing indoor heating and cooling by radiation, it is desirable to increase the area of the portion where radiation is generated, that is, the area of the first surface 54d, but the larger the area of the first surface 54d, the larger the area covering the window WD. This increases the risk that the room R will be dark.

  In the air conditioner 1d, the first surface 54d and the second surface 55d are formed of a transparent or translucent woven fabric. For this reason, the outdoor light inserted through the window WD can pass through the first surface 54d and the second surface 55d and reach the living space in the room R (see broken line arrow A9). For this reason, in this air conditioner 1d, the room is not dark even in the daytime, and a large radiation area can be secured.

(2)
As a material constituting the first surface 54d and the second surface 55d, for example, polyethylene is conceivable. Even such a transparent material can be radiated by having a certain thickness. Therefore, the room R can be sufficiently heated.

(3)
Note that not all of the radiant panel body 7d is transparent or translucent, but a part thereof may be transparent or translucent.

  Moreover, the content of this reference example may be applied with respect to the air conditioner 1c concerning embodiment.

<Other embodiments>
(1)
In the above embodiment, the radiation panel body 7a-7d has a flat plate shape, but may have another shape such as a cylindrical shape. However, the flat radiant panel main body can easily increase the area of the portion where radiation and blowing are performed, and can perform comfortable cooling and heating more efficiently.

(2)
In the above embodiment, the air in the room R is taken into the indoor unit casing 21 and sent to the radiation panel assembly 5a-5d. However, the air taken from the outside is sent to the radiation panel assembly 5a-5d. May be.

  Moreover, in said embodiment, although the radiation panel assembly 5a-5d is connected to the connection port 27 of the indoor unit casing 21, the duct exit from which air blows off is provided directly in the side wall of the room R, the ceiling surface CL, or the like. If so, the radiant panel assemblies 5a-5d may be connected to the duct outlet.

(3)
In the above embodiment, a woven fabric is used as the material of the radiation panel body 7a-7d, but a fiber-based material other than the woven fabric may be used.

(4)
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 temperature of the room R can be adjusted by radiation.
