Abstract: A refrigerating apparatus includes a refrigerating cycle including a compressor, a condenser, a flow divider, a first heat exchanger, a second heat exchanger, a decompressing device, and an evaporator. The refrigerant cycle has sealed therein a mixed refrigerant obtained by mixing at least first to third refrigerants with different evaporation temperatures. The first heat exchanger and the second heat exchanger each includes a double pipe to form a first flow passage in an inner pipe of the double pipe, a second flow passage in an outer pipe of the double pipe, and an intermediate port in a piping connecting between the second flow passage of the first heat exchanger and the second flow passage of the second heat exchanger. A high-temperature and high-pressure refrigerant discharged from the compressor is cooled by the condenser to liquefy the first refrigerant having a high evaporation temperature into a liquid refrigerant.
