By laying the floor material 15, the air duct of the second duct 7 is substantially completed. Thereby, the air-conditioning structure which attached the 1st duct 6, the 2nd duct 7, and the 3rd duct 8 to the floor structure of a building and a wall surface structure is completed.

  Now, in the said air conditioning structure, the air conditioner 33 and the air blower 31 start operation by operation of a control apparatus. Air conditioning air (cooling air for cooling, warm air for heating, air for ventilation, etc.) is blown out from the air conditioner 33, and the air for air conditioning circulates in the first duct 6. The air-conditioning air in the first duct 6 is blown out vigorously into the second duct 7 by the blowers 31 arranged at predetermined positions 6. As the air-conditioning air flows through the second duct 7, the floor material 15 above the second duct 7 is heated (floor heating) or cooled (floor cooling).

  Further, the air for air conditioning in the second duct 7 flows into the third duct 8 through the heat insulating hose 32 connected to the end of the second duct 7, and passes through the inside of the third duct 8. The air-conditioning air that has risen is blown into the room through a ventilation plate 28 from a ventilation port 27 provided above. This air-conditioning air is used as it is for air-conditioning that adjusts the indoor temperature. Also, the indoor air is sucked from a predetermined location, and part or all of it is sent again to the air conditioner 33 and used as new air conditioning air.

  In the air conditioning structure, the floor material 15 is directly warmed (or cooled) by the air-conditioning air flowing through the second duct 7, and the floor surface 15 is radiated from the floor material 15 (warm radiation, cold radiation). A comfortable and comfortable indoor air conditioning environment is provided above 3. In addition, the air conditioning air blown from the vent hole 27 enhances the indoor air conditioning capability and improves the air conditioning efficiency. In addition, since the air-conditioning air blown out does not have an air volume that would interfere with indoor athletic competitions, the competition can be performed comfortably.

  Therefore, according to the above-described embodiment, since the first duct is arranged linearly from the air conditioner, the flow of air conditioning air blown from the air conditioner into the first duct is improved, and further, the second air is blown by the blower. Air-conditioning air is forcibly blown out to the duct, and the air-conditioning air reaches every corner of a large floor area, so that there is an effect that comfortable air-conditioning can be performed on the entire room. Then, the floor material itself that forms the second duct is cooled and warmed, the indoor air conditioning is naturally cooled by the radiant heat emitted from the entire floor surface, and the radiant effect makes the room comfortable and comfortable regardless of summer or winter. Air conditioning environment can be obtained, so it can be used comfortably as a physical education facility because it does not interfere with athletics, and the air conditioning environment of the building is good and can be used comfortably as a shelter. Satisfies the diversification needs of gymnasiums.

  In addition, by dividing the underfloor space with a heat insulating sheet, it is possible to expect higher energy efficiency and energy saving compared to a structure that air-conditions the entire underfloor space, and in addition, the use of the heat insulating sheet simultaneously obtains a heat insulating effect and a duct function. The cost is reduced and the economic effect is excellent. In addition, since air-conditioning air is blown out from the vents, air-conditioning can be performed by air temperature, so that air-conditioning efficiency is improved and the number of floor vents installed in the facility can be reduced.
