摘要： A flow of refrigerant discharged from a first compressor and cooled by a radiator is branched by a first branch portion, and the branched refrigerant of one side is decompressed and expanded by a thermal expansion valve and is heat exchanged with the branched refrigerant of the other side in an inner heat exchanger. Therefore, the branched refrigerant of the other side supplied to the suction side evaporator and a nozzle portion of an ejector can be cooled, thereby improving COP. Furthermore, a suction port of a second compressor is coupled to an outlet side of the ejector so as to secure a drive flow of the ejector, and the refrigerant discharged from the second compressor and the refrigerant downstream of the thermal expansion valve are mixed to be drawn into the first compressor so that an ejector-type refrigerant cycle device can be operated stably.

摘要： An air conditioning system for a vehicle has a cool storage heat exchanger for continuing cooling operation with stored cooling energy during a compressor is stopped due to a temporal stop of an engine for the vehicle. Cooling energy is stored in the cool storage material of the cool storage heat exchanger during a normal cooling operation during which the compressor is operated by the engine. When the vehicle stops, for example before a traffic lamp, and thereby the compressor is not operated, an ejector is operated to circulate the refrigerant from the cool storage heat exchanger to an evaporator so that the cooling operation can be continued.
