Abstract
A refrigeration cycle apparatus uses a sensor that measures temperature of a plurality of refrigerant pipes in a contactless manner. A refrigeration cycle apparatus includes a refrigerant circuit in which a compressor, a heat-source-side heat exchanger, an expansion mechanism, and a use-side heat exchanger are connected in sequence. The refrigeration cycle apparatus includes a temperature detector that detects temperatures at a plurality of points in a contactless manner, and a heat-source-side controller. At least one heat-source-side heat exchanger and the use-side heat exchanger includes a plurality of refrigerant pipes through which refrigerant to be heat-exchanged flows, and a flow rate adjuster. The flow rate adjuster adjusts flow rate of the refrigerant flowing through each of the plurality of refrigerant pipes. The temperature detector detects respective temperatures of the plurality of refrigerant pipes. The heat-source-side controller controls the flow rate adjustment unit based on the temperatures detected by the temperature detector.
