Abstract

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.

Description

technical field [0001] The present invention relates to a refrigeration cycle device capable of performing exhaust heat recovery operation through simultaneous operation of cooling and hot water supply. Background technique [0002] Conventionally, there is a refrigeration cycle device equipped with a refrigerant circuit formed by connecting an outdoor heat source unit, an indoor unit, and a hot water supply unit with pipes, and the air conditioning operation and the hot water supply operation can be operated independently in one system, In addition, it is possible to perform air-conditioning operation and hot water supply operation at the same time (for example, refer to Patent Document 1 below). In this system, by performing cooling operation and hot water supply at the same time, exhaust heat during cooling can be recovered to hot water supply heat, and high-efficiency operation can be realized. [0003] In such a refrigeration cycle apparatus, capacity control is perfor...
