BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor panel provided on a base floor separately from each other, and a cold / hot water circulating pipe is arranged on the back side of the floor panel. The present invention relates to a double-floor structure of an air conditioning system for heating and cooling a space on a floor such as an interior through a panel. The present invention further provides a floor outlet for sending cold air or warm air into the room through the separated double floors, and for cooling and heating the room through the floor panel by a cooling / heating medium of a hot / cold water circulation pipe arranged on the back side of the floor panel. The present invention relates to a double-floor structure for air conditioning and heating / cooling systems.

2. Description of the Related Art As a floor blowing air-conditioning / cooling / heating apparatus of this type, as shown in FIG. 9, cold water or hot water from a cold / hot water generator 17 is already installed in a cold / hot water pipe arranged below a floor panel 6. 1. A floor radiant cooling / heating system that cools or heats the floor itself by sending and circulating water to 1 and cooling and heating the inside of the room 12 by the floor radiation, and a controlled air such as humidity or temperature from the air conditioner 29 under the floor panel 6. Is supplied to the space portion 32 on the side and is blown into the chamber 12 from the air outlet 11 formed in the vicinity of the floor panel side portion communicating with the space portion 32, and the suction port 1 at the upper portion of the chamber 1
There is known an air-conditioning / cooling / heating apparatus in combination with a so-called floor blowing air-conditioning system, which adjusts the interior of the room to an air-conditioning atmosphere by returning from 3 to the air conditioner 29 for circulation (for example, Japanese Patent No. 260219). In this case, the cold / hot water pipe 1 is fixed to the lower side of the floor panel 6 so as to be embedded in the coating material 38 having high thermal conductivity such as mortar.

With the recent progress and popularization of information processing technology, particularly when a large number of OA devices such as personal computers, copiers, telephones or facsimiles are installed in an office building, as shown in FIG. The above-mentioned O on the floor surface 40
The power supply and wiring cords 41 of the equipment A are crawled, and a large number of support legs 42 are erected on the floor 40 at predetermined intervals, and a plurality of floor panels 45 are freely opened and closed on each support leg 42. The double floor structure installed at When the OA equipment in the room is connected to the wiring cord 41, the floor panel 45 at the corresponding position is opened and the cord 41 is pulled out to be connected, and after the connection is completed, the floor panel 45 is closed.

The heat source can be used without waste.

Cords such as OA equipment stretched between the foundation floor and the floor panel are inserted into narrow guide holes for position regulation without separately providing a special guide member for position regulation. There is no need, and the cord can be laid so as to crawl between the upper side of the belt-shaped mountain-shaped support member of the hot and cold water pipe in the double floor and between the skirts of the support member, so that the cord installation work is extremely easy. Moreover, since the support members can be extended in any of vertical, horizontal, and diagonal directions between the plurality of support members arranged in columns and rows, and the rough position thereof is restricted by the support members to extend, the number of cords is large. Even if it becomes a book, it does not get entangled or shifted to the corner, and many effects can be brought about, such as opening a corresponding part of a divided floor panel and pulling out a necessary code without error.
