(Operation) Install the machine at a predetermined position indoors or outdoors and supply the upper part,
Ducts are connected to each port such as the exhaust port, and the ducts are opened at the required locations inside and outside the room.

When the blower (7) for supply air is operated in such a state to open the return air damper (b) and close the other dampers (a) and (c), the indoor return air port (5) ... Refer to the examples in the next section for more details ... The air introduced into the machine is cooled, heat is exchanged to an appropriate temperature with hot water coils (9) and (10), and an appropriate humidity is applied to the air supply port ( 2) Supply cooling and heating air into each room through the duct.

Further, when fresh outside air is required when supplying warm and cold air to the room, a part or all of the outside air is returned from the room by opening the air supply damper (a). Easily taken in with air and fed into the room.

Further, when the return air damper (b) is closed and the exhaust damper (c) is opened, indoor polluted air is discharged to the outside through the exhaust port (4), but during that time, the total heat exchanger (17)
It is intended to effectively utilize exhaust heat.

(Embodiment) Hereinafter, the embodiment of the present invention and the drawings illustrating the operation thereof will be described in detail. An air supply port (2) an outside air intake port (3) and an exhaust port (4) return to the upper part of the airframe (1).
