Abstract
The invention relates to a refrigerant circulating device which comprises a compressor, a radiator, a high-pressure side vapor-liquid separator and a subcooler, wherein the compressor is used for sucking and compressing a refrigerant; the radiator is provided with a heat dissipation part and a refrigerant outlet; the heat dissipation part is used for dissipating heat of the high-pressure refrigerant discharged from the compressor; in a supercharging part, refrigerant flow is regulated to be mixed with refrigerant flow sucked from a refrigerant suction inlet so as to reduce the speed of mixing the refrigerant flows, thereby increasing the refrigerant pressure; the supercharging part is used for branching the refrigerant flow in the heat dissipation part of the radiator; the high-pressure side vapor-liquid separator is used for separating the high-pressure refrigerant which does not contain the refrigerant of the radiator into a gas refrigerant and a liquid refrigerant; the subcooler is used for supercooling the liquid refrigerant from the high-pressure side vapor-liquid separator. An ejector can be provided with an ejector outlet connected to the refrigerant suction inlet of the compressor; a second evaporator used for evaporating the refrigerant flowing out of the ejector can be set to be provided with a refrigerant inlet connected to the ejector outlet and a refrigerant outlet connected to the refrigerant suction inlet of the compressor.
