Abstract: An ejector-type refrigeration cycle includes an ejector module integrated with a gas-liquid separation device. A length of an inlet pipe that connects a liquid-phase refrigerant outflow port of an ejector module to a refrigerant inflow port of an evaporator is shorter than a length of a suction pipe that connects a gas-phase refrigerant outflow port of the ejector module to a suction port of the compressor.

Abstract: An ejector-type refrigeration cycle device is provided with a first ejector (15) which draws refrigerant from a refrigerant suction port (15b, 24b) by using a high-speed refrigerant flow jetted from a nozzle part (15a, 24a), and a first suction-side evaporator (19) connected to the refrigerant suction port (15b) of the first ejector (15), and a second suction-side evaporator (27) connected to a refrigerant suction port (24b) of a second ejector (24). A flow amount of the refrigerant in the second ejector (24) is smaller than a flow amount of the refrigerant in the first ejector (15). The refrigerant branched at a branch part (Z2) that is positioned on a downstream refrigerant side of a radiator (13) and on an upstream refrigerant side of the first ejector (15) flows into the second ejector (24), and the refrigerant branched on a downstream refrigerant side of the second ejector (24) flows into the second suction-side evaporator (27).

Abstract: An ejector refrigeration cycle device includes: a radiator that dissipates heat from a refrigerant discharged from a compressor; an ejector module that decompresses the refrigerant cooled by the radiator; and an evaporator that evaporates a liquid-phase refrigerant separated in a gas-liquid separation space of the ejector module. A grille shutter is disposed as an inflow-pressure increasing portion between the radiator and a cooling fan blowing the outside air toward the radiator. The grille shutter is operated to decrease the volume of the outside air to be blown toward the radiator when an outside air temperature is equal to or lower than a reference outside air temperature, thereby increasing the pressure of the inflow refrigerant to flow into a nozzle passage of the ejector module.

Abstract: An ejector refrigeration cycle has a compressor, a radiator, an ejector, a swirl flow generator, an evaporator, and an oil separator. The compressor compresses refrigerant, mixed with refrigerant oil compatible with a liquid-phase refrigerant, and discharges the high-pressure refrigerant. The ejector has a nozzle and a body having a refrigerant suction port and a pressure increasing part. The swirl flow generator is configured to cause a decompression boiling in the refrigerant by causing the refrigerant to swirl about a center axis of the nozzle. The oil separator separates the refrigerant oil from the high-pressure refrigerant compressed by the compressor and guides the refrigerant oil to flow to a suction side of the compressor. The oil separator decreases a concentration of the refrigerant oil in the refrigerant, which is to flow into the swirl flow generator, so as to promote the decompression boiling of the refrigerant in the swirl flow generator.
