Abstract:
PROBLEM TO BE SOLVED: To provide a heat pump type hot-water supplier capable of simultaneously supplying hot-water, having different temperatures, to a hot-water storage tank 6 and a floor heater 9. SOLUTION: The heat pump type hot-water supplier is provided with a three- layered structural water-refrigerant heat exchanger 2 between the discharging port of a motor-driven compressor 1 for a heat pump cycle 10 and the inlet port unit of an expansion valve 3. Hot-water, having different temperatures, can be obtained by a single heat unit or the heat pump cycle 10 whereby the hot-water, having different temperatures, can simultaneously be supplied to the hot-water storage tank 6 and the floor heater 9. A motor-driven pump 5 for a first hot-water circulating route 11 is turned in reverse whereby hot-water having the temperature of about 90 deg.C is reserved in the hot-water storage tank 6 by operating the heat pump cycle 10 by a midnight electric power or the like and after stopping the operation of the heat pump cycle 10, brine is heated by the hot-water reserved in the hot-water storage tank 6 whereby the brine can be used for floor heating.
