  FIG. 15 shows a plan view of the arrangement of the floor duct member 42 (T-type floor duct member 44 and L-type floor duct member 46) and the floor member 6 in the room. When this floor duct material 42 is used, the circulation space portion 9 is formed radially, and conditioned air is blown out from the end portion of the circulation space portion 9 itself to the underfloor space portion 31.

  When air conditioning a room, the conditioned air flows through the circulation space 9 in the lower floor 29 (air conditioning in the underfloor space) and is sent from the wall surface side where the chamber 36 is provided to the other wall surface side. The conditioned air is blown out from the front end of the circulation space 9 to the underfloor space 31 and also from the end of the T-type floor duct material 44 or the L-type floor duct material 46 branched from the middle of the circulation space 9. Air-conditioned air is blown into the underfloor space 31. In addition, the conditioned air is circulated.

Also in the air conditioning structure of this floor, the conditioned air can be distributed over the entire floor lower portion 29 of the room, and the top plate portion 24 of the floor member 6 forming the floor surface 33 is heated (or cooled). In the room, radiation air conditioning from the floor is performed.
Therefore, also in this embodiment, the floor member and the floor duct material can be integrated to efficiently form a distribution space, and the floor can be efficiently air-conditioned even if the underfloor space is relatively narrow. The same effect as the above embodiment can be obtained.
