However, in the conventional double floor type air conditioning system, since the covering material 38 is filled between the cold / hot water pipe 1 and the floor panel 6, the floor panel 6 cannot be opened and closed. The wiring cord etc. cannot be laid. Further, since the cold / hot water pipe 1 is embedded in the covering material 38, the cold / hot water pipe 1 and the floor panel 6 are in indirect contact, and there is a problem in terms of thermal conductivity. Furthermore, extensive work is required for pipe replacement and repair when the cold / hot water pipe 1 is damaged or corroded.
[0005]
Also, with regard to the configuration in which the wiring cord 41 is put on the floor surface using the double floor space, conventionally, the cord 41 is merely cluttered on the floor surface, and the number of the cords 41 is large. In this case, the cords 41 become entangled, and when the position of the OA device in the room is changed, it takes time to select and reconnect the required cords, and more than necessary. There was an inconvenience of having to open the floor panel.

【The invention's effect】
As described above, according to the present invention, at least both sides and the upper side of the cold / hot water pipe are surrounded by the heat transfer member, and are supported by contacting the back surface of the floor panel of the double floor via this heat transfer member. Since it did in this way, the heat medium which flows through the inside of a pipe can be efficiently transmitted to a floor panel. Also, a gap is secured between the floor panel and the foundation floor, and air that is air-conditioned through the gap is sent from the floor panel outlet to the room, discharged from the suction port at the top of the room, and between this Since it circulates, the radiation from the floor panel by the hot and cold water pipes and the indoor air conditioning and air conditioning by the conditioned air are made effective. The air sent into the room from the outlet is also cooled and heated by the cold / hot water pipe between the double beds, and the air in the double beds touches the heat transfer member, so heat exchange with air is effective. The heat source can be used without waste.
[0018]
In addition, cords such as OA equipment stretched between the foundation floor and the floor panel do not need to be inserted through a narrow guide hole for position regulation without separately providing a special guide member or the like for position regulation. The cord installation work is very easy because it can be laid from the upper side of the band-shaped chevron support member of the cold / hot water pipe in the double floor to the skirt of the support member. In addition, the cord can be extended between any number of the support members arranged in a row and a row in any direction of length, width, and slant, and its rough position is restricted by the support members so as to extend. Even if it becomes a book, it does not get entangled or deviate toward the corner, and many effects are brought about, such as opening a corresponding part of the divided floor panel and extracting a necessary code without error.
