Abstract (en)
Providing a refrigeration cycle apparatus capable of using a refrigerant of an appropriate composition in accordance with an operating condition. The refrigeration cycle apparatus (100) includes a main refrigerant circuit (50), a changing unit (70), and a controller (110). The main refrigerant circuit uses a non-azeotropic refrigerant mixture containing a first refrigerant and a second refrigerant. The changing unit changes a composition ratio between the first refrigerant and the second refrigerant in a refrigerant flowing through the main refrigerant circuit. The controller controls an operation of the changing unit. The controller executes a first mode and a second mode. The first mode is a mode in which the operation of the changing unit is controlled to cause substantially the second refrigerant alone to flow through the main refrigerant circuit. The second mode is a mode in which the operation of the changing unit is controlled to cause a refrigerant mixture of the first refrigerant and the second refrigerant to flow through the main refrigerant circuit.
