摘要: A closed refrigerating circuit for car air conditioning includes a compressor, a condenser, a refrigerant receiver, an expansion valve, and an evaporator. The expansion valve is provided with a constant pressure controlling mechanism for maintaining a pressure in the evaporator at a constant value. The compressor is provided with a continuously variable displacement mechanism for maintaining a superheating temperature of suction refrigerant at a constant value.
