Abstract
There is provided a refrigeration cycle apparatus in which an outdoor heat source unit, an indoor unit, and a water heating unit 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 includes a compressor for compressing refrigerant, a refrigerant air-heat exchanger that performs heat exchange between the refrigerant and outside air, a fan for cooling the refrigerant air-heat exchanger, a control device that includes an inverter device for driving the compressor, and a heat sink for dissipating heat of the inverter device, and a switching element in the inverter device is constituted by an element formed by a wide bandgap semiconductor.
