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.

摘要： A mixed refrigerant including a plurality of component refrigerants circulates in a refrigeration cycle device. An expansion valve includes a power element. A filled fluid filled in the power element is one component refrigerant in the plurality of component refrigerants. A slope of a saturated vapor pressure curve of the filled fluid is larger than the slope of the saturated vapor pressure curve SV0 of the mixed refrigerant. Thereby, an opening degree of the expansion valve can be prevented from exceeding in a low-temperature region, and the opening degree corresponding to a load can be obtained in a high-temperature region.
