Abstract:
1. A refrigerant cycle device comprising: a compressor for drawing and compressing refrigerant; a condenser for cooling and condensing high-pressure refrigerant discharged from the compressor; a high-pressure side vapor-liquid separator, located at a refrigerant outlet side of the condenser, for separating refrigerant from the condenser into vapor refrigerant and liquid refrigerant; a supercooling device for supercooling the liquid refrigerant from the high-pressure side vapor-liquid separator; an ejector having a nozzle part for decompressing refrigerant from a portion downstream of the refrigerant outlet side of the condenser, a refrigerant suction port for drawing refrigerant by a high-velocity flow of refrigerant jetted from the nozzle part, and a pressure-increasing part for mixing the refrigerant jetted from the nozzle part and the refrigerant drawn from the refrigerant suction port and for pressurizing the refrigerant by reducing velocity of the refrigerant; a throttle member which decompresses the liquid refrigerant supercooled by the supercooling device; and an evaporator for evaporating refrigerant, wherein the evaporator is located at a downstream side of the throttle member and is connected to the refrigerant suction port of the ejector.
