    摘要: In a hot water supply system with a heat pump cycle, an oil separator for separating refrigerant and oil flowing from a compressor from each other is provided, and oil separated from refrigerant in the oil separator returns to the compressor through an oil returning passage after passing through an oil passage of a water heat exchanger. The water heat exchanger includes a first heat exchanging portion in which refrigerant from the oil separator and water from a tank are heat-exchanged, and a second heat exchanging portion in which oil from the oil separator and water from the tank are heat-exchanged. In the heat exchanger, a flow direction of water is set opposite to that of refrigerant and oil.
