Title:
HEAT EXCHANGER
Document Type and Number:
WIPO Patent Application WO/2015/079747
Kind Code:
A1
Abstract:
A heat exchanger equipped with: refrigerant piping (61), through which a refrigerant that circulates in a heat pump cycle flows; hot-water supply piping (71), which is connected to a hot-water supply terminal, and through which water that exchanges heat with the refrigerant flowing in the refrigerant piping (61) flows; and heating-use piping (81), which is connected to a heating device, and through which a fluid that is to be heated and that exchanges heat with the refrigerant flowing in the refrigerant piping (61) flows. The refrigerant piping (61) is wrapped in a spiral around the exterior surface (71a) of the hot-water supply piping (71). The heating-use piping (81) makes contact with the refrigerant piping (61) from the outer-circumferential side of the refrigerant piping (61), which is the opposite side from the inner-circumferential side where the hot-water supply piping (71) is arranged. This configuration provides a heat exchanger that is capable of a more efficient hot-water supply operation than the heating operation.
