ABSTRACT:
In an ejector cycle with an ejector including a nozzle for decompressing refrigerant, a refrigerant outlet is provided in an evaporator at a position upper than a refrigerant inlet. Therefore, a circulation performance of refrigerant flowing in the evaporator can be improved. Accordingly, even when a pumping capacity generated in the ejector becomes smaller, a sufficient amount of refrigerant can be drawn into the ejector from the evaporator. Thus, a refrigerant amount supplied to the evaporator can be effectively increased. Further, a control unit controls an amount of cooling air supplied to a condenser based on the temperature of the cooling air, to control a refrigerant state to be introduced to the nozzle. In this case, a pressure increasing amount in the ejector can be effectively increased, and consumption power in the compressor can be effectively increased.
