HEAT PUMP HOT WATER SUPPLY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a heat pump hot water supply device capable of reducing electric power consumption by eliminating a pump as well as having excellent device efficiency and convenience by suppressing heat radiation loss at a water circuit.

SOLUTION: The electric power consumption can be reduced by eliminating a pump as it is equipped with a heat pump cycle 5 and a hot water supply means 31, having a heat storage means 13 equipped with a plurality of latent heat storage materials 33 having different fusing point from each other and storing heat by using heat of fusion and a heat radiator 27 of the heat pump cycle 5, for supplying hot water by heat of the heat storage means 13, a use-side heat absorption means 42 for absorbing heat stored in the heat storage means 13 and a use-side heat radiation means 43 for radiating heat absorbed by the use-side heat absorption means 42. The heat pump hot water supply device having excellent device efficiency and convenience can be provided by suppressing heat radiation loss at the water circuit.
