A heat recovery type refrigeration device (1) that includes a compressor, heat-source-side heat exchangers (24, 25, 35), and multiple usage-side heat exchangers (52a, 52b, 52c, 52d), and that recovers heat among the usage-side heat exchangers by sending refrigerant from a usage-side heat exchanger functioning as a radiator for the refrigerant to a usage-side heat exchanger functioning as an evaporator for the refrigerant. In addition, one (35) of the heat-source side heat exchangers (24, 25, 35) is used as a precooling heat exchanger through which a high-pressure gas refrigerant discharged from the compressor (21) flows continuously, and a refrigerant cooler (36) which cools an electric component is connected on the downstream side of the precooling heat exchanger (35). |
