元冷凍装置。 In a binary refrigeration system that combines a high temperature side refrigeration cycle and a low temperature side refrigeration cycle by a cascade condenser that exchanges heat between the evaporator of the high temperature side refrigeration cycle and the condenser of the low temperature side refrigeration cycle,
A compression method in which the evaporator of the low-temperature side refrigeration cycle is located below the cascade condenser, and the suction pipe and discharge pipe of the compressor of the low-temperature side refrigeration cycle and the refrigerant inflow pipe and refrigerant outflow pipe to the pressure reducer are short-circuited and connected, respectively. By providing a machine bypass pipe and a pressure reducer bypass pipe and switching the switching valve, a refrigeration cycle in which a low-temperature side compressor, a condenser, a pressure reducer, and an evaporator are connected in circulation, or a low-temperature side condenser and an evaporator can be connected. A two-way refrigeration system characterized in that it is possible to select one of short-circuit refrigeration cycles connected in circulation by a bypass pipe.
