摘要： An ejector type refrigerating cycle comprises a compressor, a heat radiating device, an ejector, and a first vaporizing device, which are connected in a circuit to form a refrigerating cycle. A bypass passage is provided between an inlet port and a suction port of the ejector, so that a part of the refrigerant is bifurcated to flow through the bypass passage. A second vaporizing device is provided in the bypass passage. An internal heat exchanger is further provided between an outlet side of the heat radiating device and the inlet side of the ejector, so that the enthalpy of the high-pressure refrigerant from the heat radiating device is reduced, to thereby increase an enthalpy difference between the inlet side and outlet side of the first and second vaporizing devices. As a result, the cooling capability by the both vaporizing devices can be improved.

摘要： In an ejector-type refrigeration cycle device provided with a first compression mechanism and a second compression mechanism, a refrigerant outlet of a suction side evaporator is coupled to a refrigerant suction port of the ejector, and a second compression mechanism is provided between the suction side evaporator and the refrigerant suction port of the ejector. Thus, even in an operation condition in which suction capacity of the ejector is decreased in accordance with a decrease of the flow amount of a drive flow of the ejector, the suction capacity of the ejector can be supplemented by the operation of the second compression mechanism. Accordingly, even when a variation in the flow amount of the drive flow is caused, the ejector-type refrigeration cycle device can be stably operated.
