A ventilation/smoke exhaust unit 102 is provided at the perimeter of the room. This ventilation/smoke exhaust unit 102 sucks indoor air from an inlet 104 and sends it out to the outside of the building from an outlet 108 through an outlet 108 to the outside of the building, and from an outlet 110 down inside a window 112 to the air conditioning unit 22. It's summery. As a result, air near the window 112, which has a relatively large temperature difference with respect to the indoor living area, can be sent to the air conditioning unit 22, thereby reducing temperature changes in the room. Note that the amount of air blown out from the air outlet 108 to the outside can be adjusted arbitrarily, and in some cases, the air may be controlled so as to be emitted only in an emergency such as a fire.

In this embodiment configured in this way, the air conditioning air chamber 16, electrical wiring, and communication wiring are all installed in the slab 1.
2A and the free access floor 14, there is no need for any of these on the ceiling, and the construction and repair work is extremely simple. In addition, water pipes such as water and sewage used indoors are also connected to the free access floor 14 and the slab 12A.
It can be placed between the Incidentally, sprinkler piping, emergency lights, and other items required by law may be installed on the ceiling.

When in use, the air after the primary treatment sent from the air conditioning unit 22 is sent to an arbitrary position through the air chamber 16, and sent into the room through the duct 48 of the furniture 46 and the air conditioning/lighting units 68, 92, 98. . Since this air is sent in a desired amount only to the vicinity of the office worker working on the furniture 46, etc., it is extremely efficient compared to the conventional case where air conditioning is performed on a room-by-room basis. Furthermore, the lighting device is also efficient because it illuminates only the office space of the office worker with the desired illuminance.

In this embodiment, since the worker receives the illumination from the task light 64, it is also possible to prevent glare caused by the illumination from the ceiling being reflected on the CRT screen as in the conventional case.

Indoor air passes through the ventilation and smoke exhaust unit 102, and a part of it is sent outside from the outlet 108, and is also blown out at the outlet 110 and air-conditioned together with the air near the window, which has a relatively large temperature difference compared to the indoor living area. The air is taken into the unit 22 and sent out to the air chamber 16 again.

In the embodiments described above, the furniture 46 and the like can be connected to the electrical wiring and water pipes in the air chamber 16 through easily detachable joints.

In this embodiment, as described above, the furniture 46 and the like are arranged at arbitrary positions and communicated with the air chamber 16 via the free access floor 14.
There are no restrictions on the installation of furniture, and it is possible to solve the problem of conventional technology where the location of furniture was restricted due to restrictions on air conditioning equipment, electrical wiring, etc.

In the above embodiment, indoor air is sent to the outside on the perimeter side or to the air conditioning unit 22 via the ventilation/smoke exhaust unit 102, but it may also be sent to an air conditioning unit provided in a machine room or the like and circulated to the air chamber. Alternatively, the wall-through type air conditioning unit 22 of the above embodiment may be omitted, and the outside air may be introduced into the air chamber 14 without being air conditioned, and the air may be processed by an air conditioner installed at an appropriate position in the air chamber and then blown into the room.

In addition, in the above embodiment, since the entire area between the floor and the slab is an air chamber, it is possible to fill the areas where air leaks are a problem with joint material or install an appropriate lining, and in some cases, the entire area within the air chamber may be The air chamber may be shaped like a container by extending a cover around the periphery. If sending conditioned air to the entire area of the air chamber places a heavy burden on the air conditioner, install an appropriate amount of air inside the air chamber to prevent air from being sent under the floor in areas where it is not necessary to take out air into the room. A partition may be provided to restrict air flow.

Although the above embodiment shows a state in which the floor is a free access floor, it goes without saying that the present invention is not limited to this and can be applied to floors of other structures.
