置。 a first gas-liquid separator that compresses the non-azeotropic mixed refrigerant with a compressor, cools it with a condenser, and separates the partially condensed gas-liquid mixed refrigerant into a liquefied high-boiling point refrigerant and a residual gas refrigerant; , a first cascade heat exchanger in which the low-temperature refrigerant after depressurizing the liquid refrigerant separated in the first gas-liquid separator exchanges heat with a gas refrigerant similarly separated;
a second gas-liquid separator that separates the gas refrigerant that has passed through the cascade heat exchanger into a liquefied medium-boiling refrigerant and a residual gas refrigerant; and a low temperature after depressurizing the liquid refrigerant separated by the second gas-liquid separator. Similar to the refrigerant, the separated gas refrigerant passes through the second cascade heat exchanger for heat exchange, the gas-liquid separator as described below, and the cascade heat exchanger, and remains in the n-th cascade heat exchanger at the final stage. The gas refrigerant with low boiling point components is completely liquefied, the pressure is reduced by a pressure reducing device, and the result is led to the cooler to obtain the desired refrigeration. In a refrigeration cycle having a return path to the compressor, a low-pressure side pipe line connected to the compressor suction section and including the cooler and a cascade heat exchanger is formed in a downward slope structure with respect to the compressor. Refrigeration equipment.
