装置。 In a binary refrigeration system for cooling the inside of a freezer, in which a high-stage refrigeration cycle through which a refrigerant with a high evaporation temperature flows and a low-stage refrigeration cycle through which a refrigerant with a low evaporation temperature flows are thermally coupled by a cascade condenser, the freezer is provided with a temperature detector for detecting the temperature inside the refrigerator, and the high-stage refrigeration cycle is provided with an evaporator for cooling the refrigerator in parallel with the cascade condenser; A switching valve is provided to switch the flow of the refrigerant, and when the temperature inside the refrigerator is higher than a predetermined temperature based on the temperature sensor, the high stage side refrigeration cycle is driven and the refrigerant is transferred to the evaporator for cooling the refrigerator by the switching valve. A two-way refrigeration system characterized by comprising control means for circulating a refrigerant, driving each of the refrigeration cycles when the temperature is below a predetermined temperature, and causing the refrigerant to flow to the cascade condenser using the switching valve.
