自体は温度を降下させる。 First, in order to cool the room R, a refrigerant such as fluorocarbon is compressed and gasified by a compressor 1, and the gas is passed through a conduit 2 and a four-way valve 3 to a heat exchanger 4 in the direction of the solid arrow. The heat exchanger 4 is formed by meandering the conduit 2 itself and providing heat radiation fins around the conduit 2. During cooling, the heat exchanger 4 functions as a condenser, and the gasified refrigerant releases heat into the exhaust gas. . And the refrigerant itself lowers the temperature.

い。 Therefore, the heat exchanger 8 in the air supply duct 11 removes heat from the air supply and supplies it to the auxiliary air conditioner 12 and the air supply port 13.
Low-temperature, low-humidity air is supplied to the room R through a high-performance filter. Further, the heat removed during cooling is released together with the exhaust air by the heat exchanger 4 in the exhaust duct 21 provided separately from the air supply duct 11. The exhaust duct 21 and the air supply duct 1
1 are provided without communicating with each other, the discharged air will not be circulated back into the room R.
一方室内Ｒを暖房するには、上記冷房時の作動

れることはない。 The heat exchanger 4 operates as an evaporator, thereby removing heat from the exhaust gas and converting it into gas. At this time, heat exchanger 4
If the surface temperature of the conduit and fins is controlled to be below the dew point temperature of the exhaust gas, water vapor in the exhaust gas will condense on the surfaces of the conduit and fins, and the steam and latent heat in the exhaust gas will be efficiently recovered. Moreover, since the exhaust duct 21 and the air supply duct 11 are provided without communicating with each other, the exhaust gas from which the heat has been taken away does not flow back into the room R.
一方液化した冷媒は切換えた四方弁３を介して
蓄積槽１０に至り、圧縮器１によつてガス化され

ある。 That is, heat discharged from the room R is recovered by the heat exchanger 4, and this recovered heat is transferred to the heat exchanger 8.
This is intended to heat the room R by releasing it into the supply air.
