A refrigeration cycle apparatus avoids refrigerant conditions causing a disproportionation reaction and exhibit high performance with safety even when a refrigerant causing the disproportionation reaction is used in a zeotropic refrigerant mixture. The refrigeration cycle apparatus uses, as a working refrigerant, the zeotropic refrigerant mixture of a first refrigerant and a second refrigerant having a higher boiling point than that of the first refrigerant under the same pressure, and includes at least a main passage sequentially connecting a compressor, a first heat exchanger, an expansion valve, a gas-liquid separator, and a second heat exchanger. The first refrigerant causes the disproportionation reaction. In an initial state after startup of the compressor, the refrigeration cycle apparatus performs an initial operation decreasing a temperature or a pressure of refrigerant discharged from the compressor to be lower than that in a normal operation based on an amount of liquid refrigerant in the gas-liquid separator.
