A compressor has an outlet connected to an inlet of the condenser. A receiver dryer has an inlet connected to an outlet of the condenser. An outside expansion valve has an inlet connected to an outlet of the receiver dryer through a first passage. An outside evaporator has both an inlet connected to an outlet of the outside expansion valve and an outlet connected to an inlet of the compressor through a second passage. An inside evaporator is disposed in the air duct at a position upstream of the condenser. An inside expansion valve has both an inlet connected to the first passage and an outlet connected to an inlet of the inside evaporator. A coolant distributing circuit is further employed which feeds the inside evaporator with at least a part of coolant discharged from the receiver dryer when the coolant pressure in the inside evaporator exceeds a predetermined degree.

摘要： A compressor compresses a refrigerant. A radiator cools the refrigerant compressed by the compressor. An expansion valve receives the refrigerant from the radiator to depressurize and expand the refrigerant. An evaporator evaporates the refrigerant expanded by the expansion valve to cool air passing through the evaporator.
