  • a circulation path in which a refrigerant flows; and

    at least one compressor for compressing the refrigerant, a heat exchanger for cooling the refrigerant compressed by the at least one compressor, a cold heat recovering exchanger, at least one expansion turbine for expanding the refrigerant cooled by the heat exchanger to generate cold heat, and a cooling part for cooling an object to be cooled by the cold heat provided on the circulation path in order,wherein at least either the at least one compressor or the at least one expansion turbine comprises a plurality of compressors or expansion turbines which are arranged in parallel with one another with respect to the circulation path,wherein the cold heat recovering exchanger, the at least one expansion turbine, and the cooling part are housed together in at least one cold box insulated from the outside,wherein the at least one compressor and the heat exchanger for cooling the refrigerant compressed by the at least one compressor are housed together in at least one compressor unit other than the at least one cold box, andwherein the at least one compressor unit is placed at a position farther from the object to be cooled than the at least one cold box.
