Abstract

To provide a refrigeration cycle apparatus capable of performing efficient operation even under a low-load condition. An air conditioner (100) includes a first refrigerant circuit (110), a second refrigerant circuit (120), a bypass flow path (130), and a bypass valve (132). The first refrigerant circuit includes a first compressor (10), a radiator (40), a first expansion valve (50), and a heat absorber (60). The second refrigerant circuit connects a portion between the first compressor and the radiator and a portion between the radiator and the first expansion valve to each other and includes an economizer (70), a first valve (80), and a second compressor (20). The economizer is disposed between the radiator and the heat absorber, and the second compressor sucks a refrigerant that has passed through the economizer. The bypass flow path connects a portion between the first valve and the second compressor and a portion between the heat absorber and the first compressor. The bypass valve is disposed in the bypass flow path. The second compressor is a compressor that is smaller in displacement than the first compressor.
