Zusammenfassung:	PROBLEM TO BE SOLVED: To reduce the cost by sharing connecting parts for pipe connection between units. SOLUTION: This heat pump type hot water supply unit 10 comprises a freezing cycle having a compressor 16, a heat pump heat exchanger 18, a decompressor 28 and a gas cooler 27, where a refrigerant operating at a supercritical area in the high pressure side of the freezing cycle is packed and used. A heat pump unit 11 comprises the compressor, the heat pump heat exchanger and the decompressor, while a tank unit 12 comprises the gas cooler and a hot-water storage tank 26, where the heat pump unit and the tank unit are connected, and the two pipelines 20 between the units for circulating the refrigerant have inner diameters approximately same as each other.
