(2)
In the above embodiment, the indoor unit 2a sucks air from the suction port 24 provided on the lower surface of the indoor unit casing 23. However, the suction port 24 is the side surface, the rear surface, or both the side surface and the rear surface of the indoor unit casing 23. An indoor unit provided in may be used. For example, an indoor unit 2b as shown in FIG. 11 can be considered. This indoor unit 2b is a ceiling-mounted indoor unit provided on the ceiling surface CL of the room R, and has a thin flat shape. The indoor unit 2 b has a suction port 29 provided on the side surface of the indoor unit casing 28. Note that “side surface” and “rear surface” mean “side surface” and “rear surface” when the front side of the indoor unit where the radiation panel structure 1a is provided is defined as the front surface.

  In such an indoor unit 2b, the suction port 29 becomes difficult to enter the field of view of a resident or the like below, and the aesthetic appearance is improved.

(3)
In said embodiment, you may prevent the swelling of the bag part 40a by using a fiber-type material with a coarse fiber. Further, the bulge can be suppressed by controlling the flow rate of the air sent to the pressure generation space PS. For example, it is preferable to select a fiber-based material having a fiber mesh size such that the swelling of the bag portion 40a is equal to or less than a predetermined value with respect to the required flow rate. As a result, it is possible to suppress the bulge and blow out the air substantially uniformly downward.

  Alternatively, a double-structured bag portion 40a having a first layer for performing gentle blowing and radiation and a second layer for suppressing swelling of the first layer may be used. The first layer is formed of, for example, the above-described fiber-based material or a perforated panel whose flow rate is controlled, and the second layer is provided on the outside of the first layer, and the fibers have a coarser mesh than the first layer. Formed by no fiber-based material. Further, the second layer may be formed in a lattice shape using a material such as wood, metal, or resin. Such a configuration can also suppress the swelling of the bag portion 40a.

(4)
The material for forming the bag portion 40a is not necessarily one type, and the bag portion 40a may be formed of a plurality of different stretchable materials. For example, it is conceivable that the central portion of the lower surface of the bag portion 40a is formed of a material having a relatively low elasticity, and the peripheral portion of the lower surface of the bag portion 40a is formed of a material having a relatively high elasticity. In this case, when air is sent to the pressure generation space PS, the degree to which the bag portion 40a swells due to static pressure varies depending on the portion. Therefore, by forming the bag portion 40a from a plurality of materials having different stretch properties, the inflated bag portion 40a can be formed into a desired shape.

(5)
In the above embodiment, a tension adjuster may be disposed around the bag portion 40a. This tension adjuster is a mechanism for adjusting the tension of the bag portion 40a. When the bag portion 40a is formed of a stretchable material, the lower surface of the bag portion 40a is convexly bulged downward due to the static pressure or the own weight of the pressure generating space PS. The amount of sag downward from the lower surface increases with time. In such a case, a part of the bag part 40a may be wound up by a tension adjuster to apply tension to the bag part 40a to reduce the amount of sag. Thereby, the bag part 40a can be hold | maintained in a predetermined shape.

(6)
In said embodiment, although the bag part 40a is formed with the material which has a stretching property, it may be formed with the material which has little stretching property or does not have a stretching property. Thereby, increase of drooping of the lower surface of the bag part 40a can be prevented.

(7)
A radiation temperature sensor may be provided in the external frame 5a and the like, and a suction temperature sensor may be provided in the indoor unit to control the indoor temperature by a control unit (not shown). The radiation temperature sensor measures the radiation temperature of a target person or bedding. The suction temperature sensor measures the temperature of the room R by measuring the temperature of the air sucked into the indoor unit. The control unit controls the temperature of the blown air, the air volume, and the like based on the radiation temperature and the suction temperature. Thereby, more suitable temperature control of the room R is possible.

  Moreover, it is good also as a structure which can change the direction of said radiation temperature sensor. As a result, it is possible to measure the radiation temperature of the radiation panel 4a where the radiation temperature needs to be measured, and more appropriate temperature control of the room R is possible.

  Furthermore, the radiation temperature sensor may also serve as a human detection sensor. By detecting the entry / exit of a person into / from the room R by the radiation temperature sensor, it is possible to perform control for automatically turning on / off the air conditioner 100 in accordance with the entry / exit of the person.

(8)
The radiation panel structure 1a is provided with a pressure sensor for measuring the pressure in the pressure generation space PS in the bag portion 40a and a valve for venting air in the pressure generation space PS, and the pressure in the pressure generation space PS is reduced. Control may be performed to open the valve when a predetermined level is exceeded. Further, a valve capable of automatic adjustment that opens when reaching a predetermined pressure and closes below the pressure may be used without a pressure sensor. Thereby, the swelling of the bag part 40a can be suppressed below a predetermined level.

(9)
The bottom surface of the bag portion 40a may be configured by a plurality of blowing portions that can be blown separately, and control for blowing a fine wind toward a predetermined portion of the room R may be performed. Thereby, finer partial temperature adjustment becomes possible.

(10)
In said embodiment, although the heat insulating material 42 is being fixed to the bag part 40a, the heat insulating material 42 may be fixed to the internal flame | frame 41a. Even with such a configuration, it is possible to suppress the occurrence of condensation on the ceiling surface CL as described above.

(11)
In the above embodiment, the air in the room R is taken into the indoor unit casing 23 and sent to the radiation panel structure 1a. However, the air taken from the outside may be sent to the radiation panel structure 1a. Moreover, the air blower with which the indoor unit 2a and the outdoor unit 3 were united may be used.

(12)
In the above embodiment, the radiation panel 4a has a rectangular shape in plan view, but may have another shape. For example, other polygons such as a square or a hexagon or a circle may be used.

(13)
In the above embodiment, the radiation panel 4a and the indoor unit 2a are connected via the duct 9, but the radiation panel 4a is fixed to the indoor unit 2a, and the radiation panel 4a and the indoor unit 2a are integrated. It may be said.
