HEAT STORAGE WATER-HEATING AND AIR-CONDITIONING MACHINE |
摘要 |
A first circulation channel (14) connects a first heat demand part (401) and a first supply heat exchanger (11) with its forward route and return route. A supply channel (15) and a discharge channel (17) are connected to a first heat accumulation tank (16). The first heat accumulation tank (16) accommodates a second heat medium (10) heated in the first supply heat exchanger (11) and supplied via the supply channel (15). A heat accumulation switching valve (19) performs a changeover operation of communication of the second heat medium (10) serving as hot heat or cold heat flowing from the first supply heat exchanger (11) and supplied to the first heat demand part (401) without branching to the supply channel (15), and communication of the second heat medium (10) serving as hot heat or cold heat branching to the supply channel (15) and supplied to the first heat accumulation tank (16). A heat-accumulating hot-water-supplying air conditioner (100) is operated at the first temperature when the second heat medium (10) from the first supply heat exchanger (11) is to branch to the supply channel (15), and at the second temperature lower than the first temperature when the second heat medium (10) is not to branch to the supply channel (15). A second circulation channel (23) is provided to allow circulation independently of the first circulation channel (14), and connects the first heat accumulation tank (16) and a second heat demand part (501) which requires hot heat for hot water supply or bathtub preheating, with its forward route and return route. |
