Provided is a refrigeration cycle apparatus that can reduce cost with the use of a sensor capable of measuring the temperatures of a plurality of refrigerant pipes at a time in a contactless manner. A refrigeration cycle apparatus (100) includes a refrigerant circuit (102) in which a compressor (11), a heat-source-side heat exchanger (13), an expansion mechanism (15), and a use-side heat exchanger (22) are connected in sequence. The refrigeration cycle apparatus (100) includes a temperature detection unit (17) that detects temperatures at a plurality of points in a contactless manner, and a heat-source-side control unit (19). At least one of the heat-source-side heat exchanger (13) and the use-side heat exchanger (22) includes a plurality of refrigerant pipes (13b) through which refrigerant to be heat-exchanged flows, and a flow rate adjustment unit (13c). The flow rate adjustment unit (13c) adjusts a flow rate of the refrigerant flowing through each of the plurality of refrigerant pipes (13b). The temperature detection unit (17) detects respective temperatures of the plurality of refrigerant pipes (13b). The heat-source-side control unit (19) controls the flow rate adjustment unit (13c) on the basis of the temperatures detected by the temperature detection unit (17).
