Document Type and Number:
Japanese Patent JP6157721
Kind Code:
B2
Abstract:
A refrigeration cycle apparatus 1 includes a low-stage refrigeration cycle 10 that includes a low-stage compressor 11, a low-stage condenser 12, a low-stage pressure reducing device, and a low-stage evaporator 14, and circulates low-stage refrigerant, a high-stage refrigeration cycle 30 that includes a high-stage compressor 31, a high-stage condenser 32, a high-stage pressure reducing device, and a high-stage evaporator 34, and circulates high-stage refrigerant, a cascade condenser 40 exchanging heat between the low-stage refrigerant in the low-stage condenser 12 and the high-stage refrigerant in the high-stage evaporator 34, and a controller 50. The low-stage refrigerant is a refrigerant that undergoes disproportionation. The low-stage refrigerant is maintained at a pressure lower than a disproportionation pressure at which the low-stage refrigerant undergoes disproportionation.
