PROBLEM TO BE SOLVED: To provide a freezing device with a gas-liquid separator for actualizing highly efficient operation when constructed to introduce a gas refrigerant separated by the gas-liquid separator into an intermediate pressure portion of a compressor, and to provide a refrigerator equipped with the device. SOLUTION: The freezing device 30 comprises the compressor for compressing a refrigerant compressed by a first compression element 1A and discharging it, a radiator 2, an expansion valve 31, the air-liquid separator 4, expansion valves 12, 13 in which liquid refrigerants flowing out of the gas-liquid separator 4 circulate, heat absorbers 57, 58, a refrigerant pipe 4C for introducing the gas refrigerant into the intermediate pressure portion, and a first heat exchanger 15. The ratio of the displacement of a second compression element 1B to the displacement of the first compression element 1A of the compressor 1 is within a range of 0.6-0.8. COPYRIGHT: (C)2007,JPO&INPIT
