ヒートポンプ式温水暖房装置

Japanese Patent JP5310431

B2

[Object] It is an object of the present invention to provide a heat pump type hot-water heater capable of suppressing a temperature reduction of hot water to be sent to a heating terminal without deteriorating a degree of comfort even if hot water in a hot-water tank is used for heat exchange of hot water that is to be supplied. [Solving Means] A heat pump type hot-water heater of the present invention includes a hot-water tank 7, a heat pump cycle for heating hot water, a partition plate 8 which divides an interior of the hot-water tank 7 into an upper space and a lower space, a hot-water supply heat exchanger 18 which exchanges heat of water with heat of hot water in the hot-water tank to produce high temperature hot water, a hot water supply pump which sends hot water in the hot-water tank 7 to the hot-water supply heat exchanger 18, a heating terminal 34 which heats a room, and a heating pump 35 which sends hot water in the hot-water tank to the heating terminal 34. Hot water in the upper space is sent to the hot-water supply heat exchanger, hot water after its heat is exchanged by the hot-water supply heat exchanger is returned from a bottom of the hot-water tank, hot water in the lower space is sent to the heating terminal, and hot water after its heat is exchanged by the heating terminal is returned from the bottom of the hot-water tank.
