Abstract
A refrigeration cycle apparatus which is capable of performing matching of the volumetric flow rate without performing pre-expansion it obtained. A refrigeration circuit includes a compression unit including a main compressor and a second compressor, a gas cooler, an expansion mechanism, and an evaporator interconnected with pipes, and a sub-compression mechanism driven by power recovered by the expansion mechanism, a suction side of the sub-compression mechanism is connected to a compression process of the compression unit, a discharge side of the sub-compression mechanism is connected to an inlet side of the gas cooler, and flow rate of refrigerant flowing into the sub-compression mechanism is controlled.
