Abstract
A refrigeration cycle apparatusincludes a first compressor, a second compressorprovided in parallel with the first compressor, a radiatorfor cooling a refrigerant compressed by the compressorsand, an expanderfor recovering power while expanding the refrigerant cooled by the radiator, an evaporatorfor evaporating the refrigerant expanded by the expander, a rotation shaftconnecting the first compressorto the expanderso that the first compressoruses the power recovered by the expander, a controllerfor executing a control including a step of increasing a flow rate of the refrigerant gradually during a defrosting operation in which frost formed on the evaporatoris melted by allowing the refrigerant having a high temperature to flow through the evaporator
