Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an air conditioner.
[0002]
[Prior art]
A convection type air conditioner that blows out temperature-controlled air into a room and controls the temperature in the room is often used. This convection type air conditioner usually has an outlet through which air blown into a room passes. The outlet is, for example, an opening provided at a lower front part of the indoor unit along the longitudinal direction of the indoor unit of the air conditioner. The convection type air conditioner blows out the temperature-adjusted air from the outlet into the room, and generates convection of the temperature-adjusted air in the room. As a result, the temperature-controlled air can reach a wide area in the room, and the temperature in the room can be adjusted (see Patent Document 1).
[0003]
On the other hand, a radiation type air conditioner that adjusts indoor temperature using radiation has been conventionally known (see Patent Document 2). According to this radiant air conditioner, the temperature in the room can be adjusted by radiation, so that the temperature in the room can be adjusted more gently than in the convective air conditioner.

[Problems to be solved by the invention]
In the convection type air conditioner as described above, it is desirable that the blown air can reach farther away. This is because the temperature-adjusted air reaches a further distance, so that the temperature distribution in the room can be made more appropriate.
In order to make the blown air reach farther away, it is conceivable to specially provide a duct through which the air passes, such as behind the ceiling. By sending the air into the room through the duct, the air can reach farther. However, in this case, the cost may increase due to the provision of the duct.
[0007]
Also, in a radiation type air conditioner, if air can be blown out and air can be reached far away, more appropriate temperature adjustment can be performed.
An object of the present invention is to provide an air conditioner that can make air reach a distant place.
[0008]
[Means for Solving the Problems]
The air conditioner according to claim 1 includes a radiator and a blower. The radiator constitutes a part of an air path for sending the first air to a distant place, and adjusts the temperature of the room by radiation. The blower flows the first air through the air path.
In this air conditioner, room temperature can be adjusted by radiation from the radiation section.
[0009]
In addition, the blower flows the first air through the air path. For this reason, the first air can flow along the radiating portion and reach far. Thus, in this air conditioner, the air can be made to reach a distant place by using the radiating section.
An air conditioner according to a second aspect is the air conditioner according to the first aspect, wherein the radiator is provided near the ceiling or the side wall. Then, the blower flows the first air between the ceiling or the side wall and the radiator.
[0010]
In this air conditioner, the blower flows the first air between the ceiling or the side wall and the radiator. For this reason, the first air can reach far along the ceiling or the side wall and the radiation part. As described above, in this air conditioner, the air can be made to reach a distant place by using the ceiling or the side wall and the radiating portion as pseudo ducts.
[0011]
An air conditioner according to a third aspect is the air conditioner according to the first aspect, wherein the radiating section is provided near the ceiling or the side wall, and further includes a partition section. The partition part partitions between the ceiling or the side wall and the radiation part, and forms a part of an air path. Then, the blower flows the first air between the radiator and the partition.
In this air conditioner, the blower flows the first air between the radiator and the partition. For this reason, the first air can reach far along the radiating portion and the partition portion. As described above, in this air conditioner, the air can be made to reach a distant place by using the radiating portion and the partition portion as pseudo ducts.
[0012]
An air conditioner according to a fourth aspect is the air conditioner according to any one of the first to third aspects, wherein the radiating portion has a pressure generating space formed inside and has a plurality of holes. When the temperature-adjusted second air is taken into the pressure generating space, a pressure higher than the atmospheric pressure is generated. The second air blows out from the plurality of holes.
In this air conditioner, the temperature of the radiator is adjusted by the temperature-adjusted second air. Thereby, this air conditioner can perform indoor temperature adjustment by the radiation from the radiation part. Further, the second air whose temperature has been adjusted is blown into the room from the plurality of holes of the radiator. For this reason, this air conditioner can adjust the temperature of the room by the air blown out from the hole of the radiation part. As described above, in this air conditioner, since the radiation and the blowing of the air are used in combination, the indoor temperature can be adjusted by gentle blowing as compared with the case where the indoor temperature is adjusted only by the blowing. . For this reason, in this air conditioner, unpleasant feeling due to the draft can be reduced.
[0013]
An air conditioner according to a fifth aspect is the air conditioner according to the fourth aspect, wherein at least a part of the radiating portion is formed of a fiber-based material having a predetermined emissivity.
In this air conditioner, air whose temperature has been adjusted is blown into the room from the gaps between the fibers of the radiating section by a pressure higher than the atmospheric pressure generated in the pressure generating space. For this reason, in this air conditioner, the blowing of air from the radiation portion is gentle. Therefore, in this air conditioner, indoor air conditioning can be performed by gentle blowing and radiation.
[0014]
An air conditioner according to a sixth aspect is the air conditioner according to any one of the first to fifth aspects, wherein the blower flows the temperature-controlled first air into the air path.
In this air conditioner, the blower flows the temperature-adjusted first air through the air path. Therefore, the temperature-adjusted first air can reach a distant place. For this reason, in this air conditioner, the temperature in the room can be more uniformly adjusted, and the occurrence of temperature unevenness can be suppressed.

Connected to parts. When receiving the operation command from the remote controller 7, the control unit 6 controls each component to control the operation of the air conditioner 1.
[0021]
[Configuration of radiation panel structure]
FIG. 2 shows an external view of the radiation panel structure 5a.
The radiation panel structure 5a has a thin plate-like outer shape, and has a planar shape. Further, the radiation panel structure 5a is arranged near the ceiling CL and parallel to the ceiling CL. For this reason, the radiation panel structure 5a has a larger projected area with respect to the lower living space than other directions. The radiation panel structure 5a includes an air intake 51, a radiation part 52, a plurality of shape holding members 53a, and the like.
[0022]
The air intake 51 is a portion that takes in air whose temperature has been adjusted, and is an opening provided on one of the side surfaces of the radiant panel structure 5a. The air intake port 51 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 indoor fan 23 passes therethrough.
The radiator 52 forms an air path for sending air to a distant place together with the ceiling CL. Specifically, the gap G1 between the radiator 52 and the ceiling CL functions as an air path for sending air to a distant place. The radiator 52 adjusts the temperature of the room by radiation. The radiating portion 52 includes a first radiating surface 54, a second radiating surface 55, and three side surfaces 56, and forms a pressure generating space PS in which a pressure higher than the atmospheric pressure is generated by air.
[0023]
The first radiation surface 54 has a rectangular thin sheet-like shape, and closes the lower part of the pressure generating space PS. The first radiation surface 54 is arranged at a position facing the living space in the room in parallel with the ceiling CL. Further, the first radiation surface 54 is formed of a woven fabric having an emissivity of about 0.9.
The second radiation surface 55 has the same shape as the first radiation surface 54, and closes the upper part of the pressure generating space PS. The second radiation surface 55 has a lower surface facing the first radiation surface 54 and an upper surface facing the ceiling CL. That is, the second radiation surface 55 is disposed at a predetermined distance from the ceiling CL, and is disposed between the first radiation surface 54 and the ceiling CL. The second radiation surface 55 guides the air blown out from the outlet 28 to a distant place. That is, the second radiation surface 55 and the ceiling CL function as a pseudo duct. The second radiation surface 55 is formed of the same woven cloth as the first radiation surface 54.
[0024]
A rib 57 as shown in FIG. 4 is provided on the upper surface of the second radiation surface 55. The rib 57 is provided so as to rise upward from the second radiation surface 55 and intersect with the flow of air flowing between the second radiation surface 55 and the ceiling CL (see a white arrow A2). The plurality of ribs 57 are provided along the vicinity of both end portions of the second radiation surface 55, and are arranged at predetermined intervals from the air intake port 51 side to the tip end 59 side. The rib 57 changes a part of the air flowing between the second radiation surface 55 and the ceiling CL in a direction crossing the air flow and away from the air flow (open arrow A3). reference). Thus, the flow of air from the indoor space toward the gap G1 (see the solid arrow A4) is suppressed. In FIG. 4, only one of the ribs 57 is denoted by a reference numeral, and the reference numeral of the rib 57 is omitted.
[0025]
The three side surfaces 56 have an elongated rectangular shape, and close the sides of the pressure generating space PS except for the air intake 51. The three side surfaces 56 connect the three sides of the first radiation surface 54 and the three sides of the second radiation surface 55, respectively. The three side surfaces 56 are formed of the same woven cloth as the first radiation surface 54 and the second radiation surface 55.
Thus, the radiation panel structure 5a has a bag-like shape in which the portion other than the air intake port 51 is closed.
[0026]
The plurality of shape holding members 53a are thread-like members arranged at intervals. The plurality of shape holding members 53a have the same length, and one end is fixed to the first radiation surface 54 and the other end is fixed to the second radiation surface 55. The plurality of shape holding members 53a are arranged substantially uniformly on each plane of the first radiation surface 54 and the second radiation surface 55. When a pressure higher than the atmospheric pressure is generated in the pressure generating space PS, the shape holding member 53a holds the first radiation surface 54 and the second radiation surface 55 in a flat shape, and forms the radiation portion 52 in a plate shape. To hold. Note that in FIG. 2, only one of the shape holding members 53a is denoted by a reference numeral, and the other shape holding members 53a are not denoted by a reference numeral.
[0027]
[Operation of air conditioner]
Next, the operation of the air conditioner 1 for performing indoor air conditioning will be described.
(During cooling operation)
During the cooling operation, the indoor heat exchanger 22 functions as an evaporator to take heat from passing air. The indoor air taken into the indoor unit casing 21 from the suction port 26 by the indoor fan 23 is deprived of heat when passing through the indoor heat exchanger 22, and is cooled. The indoor fan 23 sends the cooled air (second air) to the connection port 27. In addition, the indoor fan 23 sends air at room temperature that is not subjected to heat exchange in the indoor heat exchanger 22 to the outlet 28.
[0028]
The cooled air is sent to the pressure generating space PS in the radiation section 52 through the connection port 27 and the air intake port 51 as shown in FIG. When the cooled air is sent to the pressure generation space PS, a positive static pressure greater than the atmospheric pressure is generated in the pressure generation space PS. That is, a pressure higher than the atmospheric pressure is generated in a direction perpendicular to the flow of air (see the solid arrow A1) flowing in the pressure generation space PS in parallel with the ceiling CL. For this reason, the cooled air is pushed out from the gap between the fibers of the woven fabric of the radiation part 52 and is gently blown into the room (see the solid arrow A5).
[0029]
Moreover, the radiation part 52 is cooled by contacting the radiation part 52 with the cooled air. For this reason, the cool radiation by the radiation part 52 occurs (see the broken line arrow A6).
The air at room temperature (first air) is blown through the outlet 28 into the gap G1 between the second radiation surface 55 and the ceiling CL. The air blown out from the outlet 28 flows along the second radiation surface 55 and the ceiling CL (see an outline arrow A2), passes through the tip of the second radiation surface 55, and is far away from the outlet 28 in the indoor space. (See white arrow A7). Since this air is blown out from the outlet 28 at room temperature, it flows through the gap G1 between the second radiating surface 55 and the ceiling CL, so that the cold radiating from the second radiating surface 55 and the blowing of the cooling air are performed. Thus, the ceiling CL can be prevented from being excessively cooled. For this reason, this air can suppress the occurrence of dew condensation behind the ceiling. Further, when the air blown out from the outlet 28 flows between the second radiation surface 55 and the ceiling CL, the air exchanges with the ceiling CL surface cooled by the cold radiation of the second radiation surface 55 and the cooling air. And is cooled. Therefore, when the air reaches the indoor space far away from the outlet 28 through the tip of the second radiation surface 55, the air becomes cooled air.
[0030]
As described above, in the air conditioner 1, indoor cooling is performed by gentle blowing from the gaps of the fibers of the radiating section 52, cool radiation of the radiating section 52, and air blown out from the blowing ports 28. . In addition, dew condensation behind the ceiling is prevented by the air blown out from the outlet 28.
(At the time of heating operation)
During the heating operation, the indoor heat exchanger 22 functions as a condenser to heat the passing air. The indoor fan 23 sends the heated air (second air) to the pressure generating space PS in the radiating section 52 as in the cooling operation. The indoor fan 23 sends air (first air) that is not heated and remains at room temperature to the outlet 28.
[0031]
The heated air passes through the pressure generating space PS, is pushed out from the gap between the fibers of the woven fabric, and is gently blown into the room as in the cooling operation. Also, the radiation section 52 is heated by the radiation section 52 coming into contact with the heated air. Then, heat radiation by the radiation part 52 occurs.
The air remaining at room temperature is blown out to the gap G1 between the second radiating surface 55 and the ceiling CL through the outlet 28 in the same manner as in the cooling operation. The air blown out from the outlet 28 flows along the second radiating surface 55 and the ceiling CL, passes through the tip of the second radiating surface 55, and reaches an indoor space far away from the outlet 28. When the air blown out from the outlet 28 flows through the space between the second radiation surface 55 and the ceiling CL, the air exchanges with the ceiling CL surface heated by the heat radiation of the second radiation surface 55 and the heated air. Heating. For this reason, when the air blown out from the outlet 28 reaches the indoor space far away from the outlet 28 through the tip of the second radiation surface 55, the air is heated.
[0032]
As described above, in the air conditioner 1, indoor heating is performed by gentle blowing from the gaps of the fibers of the radiating section 52, heat radiation of the radiating section 52, and air blown out from the blowing port 28. .
[Prevention of dirt during operation]
As described above, when the cooling operation or the heating operation is performed, the ceiling CL may be stained. That is, when the air blown out from the outlet 28 flows through the gap G1 between the second radiating surface 55 and the ceiling CL, the surrounding air is entrained in this flow, and from the indoor space as shown in FIG. A flow of air toward the gap G1 (see a solid arrow A4) occurs. Then, along with the flow of air, dirt in the air collects near the ceiling CL, thereby causing dirt on the ceiling CL.
[0033]
However, in the air conditioner 1, the rib 57 is provided on the upper surface of the second radiation surface 55. A part of the air blown out from the outlet 28 is diverted to the side by the rib 57. That is, a part of the air blown out from the outlet 28 flows in a direction crossing the flow of the air blown out from the outlet 28 and in a direction away from the flow of the air. Therefore, the flow of air from the indoor space toward the gap G1 is suppressed. This prevents dirt from being entrained along with the entrainment of air, and prevents dirt from adhering to the ceiling CL.
[0034]
[Characteristic]
(1)
In this air conditioner 1, the ceiling CL and the second radiation surface 55 are used as pseudo ducts. For this reason, the air blown out from the outlet 28 can reach far away.
[0035]
Further, since the ceiling CL and the second radiation surface 55 are used as pseudo ducts, there is no need to provide a duct behind the ceiling, and the cost is reduced.
(2)
Generally, dust may accumulate on equipment placed indoors, including air conditioners. In particular, as described above, when the radiation panel structure 5a is arranged in parallel with the ceiling CL, dust easily accumulates on the upper surface of the second radiation surface 55.
[0036]
In the air conditioner 1, air flows through the gap G1 between the ceiling CL and the second radiation surface 55. For this reason, the accumulation of dust on the second radiation surface 55 is prevented.
(3)
In the air conditioner 1, the air blown out from the outlet 28 is cooled or heated by the second radiation surface 55, so that the cooled or heated air can reach a distant place. For this reason, the temperature in the room is more uniformly adjusted, and uneven temperature is eliminated.
[0037]
Further, the temperature of the distant side wall and the window far away from the air conditioner 1 can be adjusted by strengthening the blowing by the indoor fan 23 to make the air reach the distant side wall and the window. Thereby, the heat radiation from the side wall and the window is reduced during the cooling operation, and the cool radiation and the flow of the cool air from the side wall and the window are reduced during the heating operation. For this reason, the temperature unevenness in the room caused by these factors is eliminated. In addition, dew condensation generated in windows and the like is eliminated.
[0038]
(4)
In the case of a convection type air conditioner that blows out temperature-controlled air directly into a room, a so-called draft, in which the blown air directly hits a resident or the like, is likely to occur. When such a draft occurs, residents often feel discomfort. Further, even if the temperature inside the room is adjusted by blowing air, there is a risk that the draft will deteriorate the perceived temperature of the occupants and the like.
[0039]
In the air conditioner 1, as described above, the room can be cooled and heated by the radiation and the gentle blowing of the air. In addition, the air flowing through the gap G1 reaches far inside the room by the second radiation surface 55 and the ceiling CL. For this reason, there is little possibility that the wind will hit the resident or the like directly. Thus, in the air conditioner 1, the discomfort caused by the draft is eliminated.
[0040]
(5)
In a conventional air conditioner that performs air conditioning by radiation, a metal radiation panel having a high emissivity is often used.
In the air conditioner 1, the radiating portion 52 is formed of a woven fabric, and the woven fabric has an emissivity of about 0.9. For this reason, even if it is a woven cloth, indoor cooling and heating by radiation can be performed sufficiently effectively.
[0041]
Further, the temperature of the inside of the radiating section 52 reaches the outside of the first radiating surface 54 due to the air blown out from the gap between the fibers of the woven fabric. Therefore, it is possible to efficiently perform the cooling and heating of the room by the radiation.
(6)
In the air conditioner 1, the radiant panel structure 5 a is detachably attached to the connection port 27 of the indoor unit casing 21. Therefore, it is easy to remove the radiant 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.
[0042]
The radiating section 52 is formed of a woven cloth. Therefore, when dirt adheres to the radiating section 52, the radiating panel structure 5a can be removed and cleaned.
<Second embodiment>
[Constitution]
In the air conditioner 1 according to the second embodiment of the present invention, the air whose temperature has been exchanged by the indoor heat exchanger 22 and whose temperature has been adjusted is blown out from the outlet 28. The indoor fan 23 flows the temperature-adjusted air (first air) into the gap G1 between the second radiation surface 55 and the ceiling CL.
[0043]
Other configurations are the same as those of the air conditioner 1 according to the first embodiment.
Note that the temperature of the air blown out from the outlet 28 and the temperature of the air sent to the pressure generating space PS may not be adjusted by the same indoor heat exchanger 22, but may be adjusted by different heat sources. .
[Characteristic]
In the case of a convection type air conditioner that has been often used in the past, there is a possibility that a large temperature difference may occur between places in a room. In other words, a temperature difference is likely to occur between a place where the blown air reaches well and a place where the blown air hardly reaches. If a large temperature difference occurs depending on the location, the difference in comfort and discomfort depending on the location increases. In addition, a large temperature difference may occur in the height direction of the room.
[0044]
In the air conditioner 1, by increasing the surface area of the first radiation surface 54, radiation and gentle blowing of air can be performed from the vicinity of the ceiling CL to a wide range of the living space in the room. In addition, the second radiation surface 55 and the ceiling CL are used as pseudo ducts to reach the distant portion far from the air conditioner 1 where temperature adjustment is difficult to be performed, so that the temperature-adjusted air reaches the portion. Can be done. For this reason, the whole room can be warmed or cooled more uniformly. Accordingly, it is possible to prevent an unpleasant temperature difference from occurring depending on the location in the room. Therefore, this air conditioner 1 can eliminate the discomfort of the occupants and the like. Further, even when a plurality of occupants and the like are indoors, it is possible to generate a temperature environment that is comfortable for many occupants and the like.
[0045]
The radiant panel structure 5a is disposed near the ceiling CL and has a thin plate shape. For this reason, even if the surface area of the first radiation surface 54 facing the living space is relatively large, there is little possibility that the first radiation surface 54 will obstruct the occupants.
<Third embodiment>
[Constitution]
FIG. 6 shows a radiation panel structure 5b of the air conditioner 1 according to the third embodiment of the present invention.
[0046]
The radiation panel structure 5b has a partition surface 58 between the radiation part 52 and the ceiling CL. The partition surface 58 partitions between the ceiling CL and the second radiation surface 55. The indoor fan 23 sends air to a gap G2 between the second radiation surface 55 and the partition surface 58 and a gap G3 between the partition surface 58 and the ceiling CL. The air sent to the gap G2 between the second radiation surface 55 and the partition surface 58 (first air, see the outline arrow A8) is air whose temperature has been adjusted in the indoor heat exchanger 22. The air (see the white arrow A9) sent to the gap G3 between the partition surface 58 and the ceiling CL is room temperature air that has not been temperature-controlled. The partition surface 58 and the second radiation surface 55 guide the temperature-regulated air to a distant place. Further, air at room temperature flows between the partition surface 58 and the ceiling CL.
[0047]
Other configurations are the same as those of the air conditioner 1 according to the first embodiment.
[Characteristic]
(1)
In this air conditioner 1, the indoor fan 23 allows the temperature-controlled air to flow through the gap G2 between the second radiation surface 55 and the partition surface 58. For this reason, the air whose temperature has been adjusted can flow along the second radiation surface 55 and the partition surface 58 to reach a distant place. In this way, in the air conditioner 1, the second radiation surface 55 and the partition surface 58 are used as pseudo ducts, so that air can reach far away. The temperature of the room is also adjusted by the radiation from the first radiation surface 54 and the blowing. As described above, in the air conditioner 1, the temperature in the room can be adjusted more uniformly, and the temperature unevenness in the room can be eliminated.
[0048]
(2)
In this air conditioner 1, the indoor fan 23 allows air at room temperature to flow through the gap G3 between the partition surface 58 and the ceiling CL. For this reason, the ceiling back is prevented from being excessively cooled, and the occurrence of dew condensation on the ceiling back is prevented.
<Other embodiments>

In the above embodiment, the radiation panel structure 5a is arranged near the ceiling CL, but the radiation panel structure 5a may be arranged along the vicinity of the indoor side wall WL (see FIG. 1). In this case, air flows between the side wall WL and the second radiation surface 55 arranged to face the side wall WL.
[0049]
(2)
In the above embodiment, the first radiating surface 54 and the second radiating surface 55 are formed of a fibrous material having flexibility, but may be formed of a rigid material such as a metal material. In this case, by providing a plurality of holes in the first radiation surface 54 and the second radiation surface 55, the same effect as described above can be obtained.
[0050]
Further, in the above embodiment, the woven fabric is used as the material of the first radiating surface 54 and the second radiating surface 55, but a fibrous material other than the woven fabric may be used.
(3)
In the above embodiment, a woven fabric having an emissivity of 0.9 is used, but a woven fabric having an emissivity of 0.6 or more, more preferably 0.7 or more or 0.8 or more is used. Good. Further, the emissivity may be 0.6 or less depending on the required emissivity and application, and in this case, the room temperature can be adjusted.
[0051]
(4)
In the above embodiment, the radiant 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 is provided directly on the side wall WL, ceiling CL, or the like in the room. The radiation panel structure 5a may be connected to the duct outlet.

【The invention's effect】
In the air conditioner according to the first aspect, the temperature in the room can be adjusted by radiation from the radiation section.
In addition, the blower flows the first air through the air path. For this reason, the first air can flow along the radiating portion and reach far. Thus, in this air conditioner, the air can be made to reach a distant place by using the radiating section.
[0054]
In the air conditioner according to the second aspect, the blower flows the first air between the ceiling or the side wall and the radiator. For this reason, the first air can reach far along the ceiling or the side wall and the radiation part. As described above, in this air conditioner, the air can be made to reach a distant place by using the ceiling or the side wall and the radiating portion as pseudo ducts.
[0055]
In the air conditioner according to the third aspect, the blower flows the first air between the radiator and the partition. For this reason, the first air can reach far along the radiating portion and the partition portion. As described above, in this air conditioner, the air can be made to reach a distant place by using the radiating portion and the partition portion as pseudo ducts.
[0056]
In the air conditioner according to the fourth aspect, the temperature of the radiating section is adjusted by the temperature-adjusted second air. Thereby, this air conditioner can perform indoor temperature adjustment by the radiation from the radiation part. Further, the second air whose temperature has been adjusted is blown into the room from the plurality of holes of the radiator. For this reason, this air conditioner can adjust the temperature of the room by the air blown out from the hole of the radiation part. As described above, in this air conditioner, since the radiation and the blowing of the air are used in combination, the indoor temperature can be adjusted by the gentle blowing as compared with the case where the indoor temperature is adjusted only by the blowing. . For this reason, in this air conditioner, unpleasant feeling due to the draft can be reduced.
[0057]
In the air conditioner according to the fifth aspect, the air whose temperature has been adjusted is blown into the room through the gap between the fibers of the radiating portion by the pressure higher than the atmospheric pressure generated in the pressure generating space. For this reason, in this air conditioner, the blowing of air from the radiation portion is gentle. Therefore, in this air conditioner, indoor air conditioning can be performed by gentle blowing and radiation.
[0058]
In the air conditioner according to the sixth aspect, the blower flows the temperature-adjusted first air through the air path. Therefore, the temperature-adjusted first air can reach a distant place. For this reason, in this air conditioner, the temperature in the room can be more uniformly adjusted, and the occurrence of temperature unevenness can be suppressed.
