Document Type and Number:
WIPO Patent Application WO/2014/038028
Kind Code:
A1
Abstract:
A refrigerating device comprises: a high-temperature side refrigerating cycle configured so a high-temperature side compressor, a high-temperature side condenser, a high-temperature side throttle, and the evaporation side of a cascade condenser are connected by refrigerant piping; and a low-temperature refrigerating cycle configured so a low-temperature side compressor, the condenser side of the cascade condenser, a liquid receiver, a low-temperature side throttle, and a low-temperature side evaporator are connected by refrigerant piping. The liquid receiver comprises a container that has a capacity of 5 to 7 times the volume of the liquid refrigerant filling the low temperature refrigeration cycle when all the refrigerant is liquid refrigerant.
