To provide a refrigerating device capable of suppressing the clogging of a strainer caused by an oxidized scale by reducing an amount of refrigerating machine oil passing through the strainer, as a result, capable of increasing a capturing capacity of the strainer 60, and surely returning the refrigerating machine oil to a compressor to improve the durability of the compressor and to exert a prescribed refrigerating capacity by keeping the prescribed refrigerant circulation amount per a unit time during a refrigerating cycle.

In the refrigerating device in which an oil separator 17 is disposed in a discharge pipe of the compressor 16, a gas-liquid separator 15 is disposed in a suction pipe 63 of the compressor 16, and the refrigerating machine oil separated by the oil separator 17 is returned to the suction pipe 63, the strainer 60 is disposed in an outlet pipe of the gas-liquid separator 15, and an oil return pipe 62 is connected to the suction pipe 63 between the strainer 60 and the compressor 16.
