HEAT PUMP TYPE HOT-WATER SUPPLY UNIT, AND CONTROLLER FOR HEAT PUMP TYPE HOT-WATER SUPPLY UNIT

摘要

PROBLEM TO BE SOLVED: To provide a heat pump type hot-water supply unit capable of additionally enhancing energy efficiency, in the compact hot-water supply unit capable of using hot water supply by an operation of a heat pump device in combination with hot water supply from a hot-water storage tank, when using the hot water.;SOLUTION: This controller 100 operates the heat pump device 2 to boil up the hot water of a medium temperature, when supplying the hot water to a using terminal side, and supplies directly the hot water via the second hot-water supply pipe 24. After the direct hot water supply, the heat pump device 2 is operated continuously to store replenishingly the hot water of high temperature in the hot-water storage tank 1, when a heat quantity is insufficient in the hot-water storage tank 1. The hot water of the medium temperature is also preferentially supplies from the hot-water storage tank 1, when a hot-water supply heat quantity is not enough in the direct hot water supply, so as to use effectively the hot water of the medium temperature generated in the hot-water storage tank 1.;COPYRIGHT: (C)2007,JPO&INPIT
