Abstract:
1. A heat pump-type hot water feeding apparatus comprising: a cooling cycle circuit configured so that coolant flows through a compressor, an indoor heat exchanger, an expander, and an outdoor heat exchanger; a heat storage tank that stores heat exchanged with coolant branched from the cooling cycle circuit; and a hydro kit heat exchanging unit that includes a first heat exchanger that performs heat exchange between a first heat transfer fluid and coolant compressed in a supersaturated region by the compressor and primarily condenses the coolant and a second heat exchanger that performs heat exchange between the primarily condensed coolant and a second heat transfer fluid and secondarily condenses the coolant, wherein the hydro kit heat exchanging unit is connected to the cooling cycle circuit, wherein during a heat storage mode operation that stores heat in the heat storage tank, heat of the first heat transfer fluid, the first heat transfer fluid is heat exchanged in the first heat exchanger, is stored in the heat storage tank or heat of the first heat transfer fluid, the first heat transfer fluid is heat exchanged in the first heat exchanger and heat of the second heat transfer fluid, the second heat transfer fluid is heat exchanged in the second heat exchanger, are simultaneously stored in the heat storage tank.
