PURPOSE:To accumulate heat in circulating water by a method wherein a heat exchanger, in which heated air acting as a heat medium and water are contacted directly and the conduction of the heat is assisted by utilizing the function of a partitioning plate, and a water reserving tank are constituted integrally. CONSTITUTION:The water in the tank is pumped up from the lower part of the water reserving tank 7 into a vessel 1 by a pump 8 and is circulated into the water reserving tank 7 again through an inlet port 3 and an outlet port 4, therefore, the temperature keeping energy of the heated air is retrieved and accumulated as the hot-water in the tank. However, when the amount of solar radiation is insufficient in such a time as a rainy day or night, a fan and the pump 8 may be stopped automatically by a sunshine meter. The hot water in the tank may be taken out therefrom by opening a hot-water supply valve 9 and decreasing of reserved water due to the supply of the hot-water may be supplemented from city water pipe 12 by regulating automatically a solenoid valve 11 cooperating with a level meter 10. Accordingly, the water level may be kept in constant at all times, however, if surplus water is produced, it is removed to the outside through an overflow port 13. |
