Abstract
A refrigeration cycle apparatus in which working refrigerant is a zeotropic refrigerant mixture containing at least a first refrigerant and a second refrigerant having a higher boiling point than the first refrigerant at the same pressure, the refrigeration cycle apparatus including at least a main passage in which a compressor, a first heat exchanger, a first expansion valve, and a second heat exchanger are sequentially connected, the first refrigerant having a property of disproportionation, the first refrigerant having a smaller composition ratio in the compressor than a composition ratio of the first refrigerant passing through the main passage.
