Abstract (en)
Provided is a refrigeration cycle apparatus capable of efficiently performing a cooling operation and a heating operation using a low-pressure refrigerant and a high-pressure refrigerant. A refrigeration cycle apparatus (1) performs a heating operation by performing a two-stage refrigeration cycle, the two-stage refrigeration cycle including a use-side refrigeration cycle using a first refrigerant having 1 MPa or less at 30°C and a heat-source-side refrigeration cycle using a second refrigerant having 1.5 MPa or more at 30°C, and performs a cooling operation by performing a single-stage refrigeration cycle using the first refrigerant.
