Abstract
An air-conditioning and refrigerating system has a single vane-type rotary compressor, a single condenser, an air-conditioning evaporator and a refrigerating evaporator parallel to the air-conditioning evaporator. The compressor has main and auxiliary suction ports connected through air conditioning and refrigerating refrigerant return passages to the air-conditioning evaporator and to the refrigerating evaporator, respectively. The compressor is constructed such that the refrigerating refrigerant returned through the auxiliary suction port into a working chamber is mixed in the working chamber with the air-conditioning refrigerant returned through the main suction port into the working chamber before the refrigerating refrigerant is compressed in the working chamber.
