The cool air or warm air blown into the room 7 from the air outlet 16</b>D is used for convective air conditioning of the room 7 .

A third filter 17 is provided for each of the outlets 16A to 16D. The third filter 17 is a filter intended to prevent objects from falling, as described above.

Next, the radiation panel groups 18A-18D will be described with reference to FIGS. 1-3 and 7. FIG. In FIG. 7, the same components as those of the structure shown in FIG. 3 are denoted by the same reference numerals.
The radiation panel groups 18A to 18D each have four radiation panels out of the radiation panels 68A to 68P. Radiation panels 68A-68P are radiation panels having the same configuration.

Before describing the radiation panel group 18A to 18D in detail, the configuration of the radiation panels 68A to 68P will be described by taking the radiation panel 68A as an example (see FIG. 3).

The radiation panel 68A has a housing 71, channel forming members 73 to 75 that partition a channel 78, and a damper 76 (channel switching unit). The housing 71 has a rectangular parallelepiped outer shape and has a hollow portion inside.

The housing 71 has an air inlet port 71A formed on one side in the X direction and an air outlet port 71B formed on the other side in the X direction.
71 A of air introduction ports are arrange|positioned in the corner|corner vicinity of the housing|casing 71. FIG. The air introduction port 71</b>A guides cold air or warm air through the air guiding duct 14 into the housing 71 . The air inlet 71A exposes an end face 71a of the housing 71 perpendicular to the Y direction and an end face 71b of the housing 71 perpendicular to the X direction. The end surfaces 71a and 71b are surfaces with which the damper 76 abuts.
The air outlet 71B is formed to face the air inlet 71A in the X direction.

The flow path forming members 73 to 75 are rectangular parallelepiped members that partition a flow path 78 in the housing 71 and are accommodated in the housing 71 . The flow path forming members 73 to 75 are arranged with intervals in the X direction.

The channel 78 has a bypass channel 81 and a radiant air conditioning channel 82 .
The bypass channel 81 is a channel extending in the X direction, and communicates the air inlet port 71A and the air outlet port 71B. The bypass flow path 81 is a flow path through which cool air or warm air flows when cold air or warm air is not supplied to the radiant air conditioning flow path 82 (that is, when the radiant air conditioning flow path 82 is bypassed). In addition, when cool air or warm air is supplied to the radiant air conditioning flow path 82 , cool air or warm air is also supplied to a part of the bypass flow path 81 .

The radiant air conditioning flow path 82 is a flow path having a longer flow path length than the bypass flow path 81 . The radiant air conditioning flow path 82 has a first flow path portion 82A and second flow path portions 82B to 82E.
The first channel portion 82A faces the bypass channel 81 with the channel forming members 73 to 75 interposed therebetween in the Y direction.

The second channel portions 82B to 82E are channel portions extending in the Y direction. The second flow path portion 82B is formed between one side of the housing 71 in the X direction and the flow path forming member 73 . The second flow path portion 82C is formed between the flow path forming member 73 and the flow path forming member 74. As shown in FIG.
The second flow path portion 82D is formed between the flow path forming member 74 and the flow path forming member 75. As shown in FIG. The second flow path portion 82E is formed between the flow path forming member 75 and the other side of the housing 71 in the X direction.
Among both end portions of the second flow passage portions 82B to 82E located in the Y direction, one end portion communicates with the first flow passage portion 82A, and the other end portion communicates with the bypass flow passage 81. are doing.

Since the radiant air-conditioning flow path 82 has the first and second flow path portions 82A to 82E having such a configuration, the radiant panel 68A can be A portion of the flooring 4 located above can be radiantly air-conditioned.

The damper 76 is accommodated in the housing 71 so as to be able to abut against the end surfaces 71a and 71b and to be rotatable in the C direction.
The damper 76 is electrically connected with the control device 28 . The control device 28 performs control to rotate each damper 76 so as to contact one of the end faces 71a and 71b.
The damper 76 functions as a channel switching unit that switches whether to supply cool air or warm air to the radiant air conditioning channel 82 .

In the present embodiment, the damper 76 is described as an example of the flow path switching section, but a flow path switching section other than the damper 76 may be used.

As shown in FIG. 7, when the damper 76 is in contact with the end face 71a, cold or warm air introduced into the housing 71 passes only through the bypass flow path 81, and thus hardly contributes to radiant air conditioning.
On the other hand, when the damper 76 is in contact with the end surface 71b, the cool air or warm air introduced into the housing 71 flows into the second flow path portion 82B. Therefore, cold air or warm air flows through the first flow path section 82A and the second flow path sections 82C to 82E after passing through the second flow path section 82B, contributing to radiant air conditioning.
