Abstract:
A heat pump type hot water supply apparatus for heating water by refrigerant heat and stocking the hot water thus achieved, comprising:a heat pump unit having a refrigerant circuit using natural refrigerant, said refrigerant circuit including a compressor for compressing refrigerant, a heat pump heat exchanger and a refrigerant-water heat exchanger for performing the heat exchange between refrigerant and water to achieve hot water; a hot water supply unit including a hot water supply tank for stocking the hot water achieved by said refrigerant water heat exchanger of said heat pump unit; a water pipe through which said refrigerant-water heat exchanger of said heat pump unit and said hot water supply tank of said hot water supply unit are connected to each other to circulate hot water/water between said refrigerant water heat exchanger and said hot water supply tank; and a hot-water control which mixes hot water elements supplied by the two inner portions of the hot water supply tank, each hot water element of different temperature, with a second water source, thereby adjusts the overall temperature of said mixture to a temperature ready for end user use and which supplies said mixture to an output for said end user use.
