ABSTRACT:
The evaporator and the condenser are disposed in a duct. First bypass passage is disposed at the side of the condenser and first air mixing damper rotates to control air bypassing amount. Further second bypass passage is formed at the side of the evaporator and second mixing damper rotates to control air bypassing amount. Cooling rate at the evaporator and heating rate at the condenser are varied so that air adjusted in proper temperature is generated and discharged from each outlets into a room. An outside heat exchanger is disposed the outside of the duct. Refrigerant flow is randomly switched among the outside heat exchanger, the evaporator and the condenser so that cooling, heating, dehumidifying, dehumidified-heating and defrosting operations are performed.
