To efficiently control oil flowing out to a refrigerant circuit in a refrigerating device.
This refrigerating device 1 comprising a first compressor 11 for compressing a gas refrigerant, a second compressor 14 for further compressing the gas refrigerant compressed by the first compressor 11, a radiator 15 for radiating heat of the gas refrigerant compressed by the second compressor 14, a flow divider 16 for dividing the refrigerant from the radiator 15 into a first refrigerant flow channel and a second refrigerant flow channel, a first pressure reducer 17 for reducing a pressure of the refrigerant flowing in the first refrigerant flow channel, and a heat exchanger 18 for cooling the refrigerant flowing in the second refrigerant flow channel by evaporating action of the refrigerant of which a pressure is reduced by the first pressure reducer 17, and constituted to reduce the pressure of the refrigerant after cooled by the heat exchanger 18 by a second pressure reducer 19, then evaporate the refrigerant by the evaporator 20, and supply the refrigerant to a suction side of the first compressor 11, is further provided with an oil separator 16a for separating the oil included in the refrigerant from the radiator 15, and supplying the separated oil to a first pressure reducer 17 side with the refrigerant flowing in the first refrigerant flow channel.
