PROBLEM TO BE SOLVED: To provide a refrigerator capable of reducing the power consumption even when placed in cooling operation throughout a year.SOLUTION: A refrigerator is provided with: a high-pressure heat exchanger 11; a first decompression part 21; a second gas-liquid separator 22; an ejector 23; a first gas-liquid separator 24; a second decompression part 25; a low-pressure heat exchanger 26; a suction flow passage to which a first compression part 27 is so connected as to circulate a refrigerant and which is provided with a second compressor 28 sucking a gas refrigerant from the second gas-liquid separator 22 so as to guide a refrigerant flowing out of the low-pressure heat exchanger 26 to the ejector 23; a first bypass part 31 which guides a refrigerant flowing out of the high-pressure heat exchanger 11 to the ejector 23; a second bypass part 32 which guides the refrigerant flowing through the first bypass part 31 to the second decompression part 25; a third bypass part 33 which guides the refrigerant flowing out of the low-pressure heat exchanger 26 to the first gas-liquid separator 24; control valves 41-46 which control the flows of the refrigerants; and a control part 70 which controls at least the control valves 41-46. |
