Refrigerating device and refrigerator

摘要

An object is to provide a refrigerating device capable of realizing a high-efficiency operation in a case where a compressor having an intermediate pressure section is applied, and a refrigerator including this refrigerating device. A refrigerating device 30 includes: a compressor 1 ; a radiator 2 ; an expansion valve 3 ; a gas-liquid separator 4 ; and a heat absorbing unit 8 through which a liquid refrigerant discharged from this gas-liquid separator circulates. The refrigerating device further includes: a refrigerant pipe in which the refrigerant discharged from the heat absorbing unit 8 can be introduced into a suction port of the compressor 1 and which introduces a gas refrigerant separated by the gas-liquid separator 4 into the intermediate pressure section of the compressor 1 ; and a refrigerant pipe which introduces an intermediate-pressure refrigerant of the compressor 1 into the gas-liquid separator 4.
