There is provided a refrigeration cycle apparatus in which an outdoor heat source unit (1; 1a), an indoor unit (2), and a water heating unit (3) are connected, and an air conditioning operation and a water heating operation can be performed separately, and an exhaust-heat recovery operation can be performed by simultaneously performing air cooling and water heating. The outdoor heat source unit (1; 1a) includes a compressor (13) for compressing refrigerant, a refrigerant air-heat exchanger (11) that performs heat exchange between the refrigerant and outside air, a fan for cooling the refrigerant air-heat exchanger (11), a control device (17; 17a) that includes an inverter device (14) for driving the compressor (13), and a heat sink (19; 19a) for dissipating heat of the inverter device (14), and a switching element (15) in the inverter device (14) is constituted by an element formed by a wide bandgap semiconductor. |
