Title:
REFRIGERATION CYCLE APPARATUS
Document Type and Number:
Japanese Patent JP2019211118
Kind Code:
A
Abstract:
To save power of a refrigeration cycle apparatus having an ejector and an accumulator.SOLUTION: A refrigeration cycle apparatus comprises: a first decompression part 13; a branch part 16 branching a refrigerant decompressed by the first decompression part 13; a second decompression part 17 decompressing one of the refrigerants branched at the branch part 16; an ejector 14 having a nozzle part 14 decompressing the other refrigerant branched at the branch part 16, a refrigerant suction port 14b for sucking the refrigerant by suction action of the refrigerant jetted from the nozzle part 14a, and a pressure increasing part 14d mixing the refrigerant jetted from the nozzle part 14a and the refrigerant sucked from the refrigerant suction port and increasing the pressure of the mixed refrigerants; a suction-side heat exchanger 18 in which the refrigerant decompressed at the second decompression part 17 flows, and the refrigerant is sucked to the refrigerant suction port 14b; an outflow-side heat exchanger 15 in which the refrigerant with pressure increased at the pressure increasing part 14d flows, and the refrigerant flows out toward a compressor 11; and a control part 30 controlling a throttle opening of the first decompression part 13 so that a supercooled degree of the refrigerant flowing out from the radiator 12 becomes a prescribed supercooled degree.SELECTED DRAWING: Figure 1
