凍装置。[Claims for Utility Model Registration] At least two or more independent refrigeration circuits are combined via a cascade condenser, and the low-temperature side refrigeration circuit is a closed loop consisting of a compressor, the cascade condenser, a pressure reducer, and an evaporator in series. In a low-temperature refrigeration system of a multi-component refrigeration system formed by connecting, a mixed refrigerant with a high boiling point and a low boiling point is used as the refrigerant in the low-temperature side refrigeration circuit, while a high-boiling point mixed refrigerant is used between the compressor and the cascade condenser. A condenser that liquefies only the refrigerant and a gas-liquid separator that separates the liquefied high-boiling refrigerant from the low-boiling refrigerant that is in the gas phase are installed in series, and the refrigerant is separated by the gas-liquid separator. A multi-component refrigeration cryogenic refrigeration system, wherein the refrigerant in a vapor phase is led to the cascade condenser, while the liquid refrigerant is led directly to the pressure reducer via a bypass path.
