る。 In the above configuration, first, heat collection operation is performed by sensor 2.
6 and the high temperature sensor 25 is detected, and the heat collecting pump 14 is operated. Then, the heat medium B sucked in from the bottom outlet 1a of the heat storage tank 1 by the pump 14 flows to the heat collector 12, where it is heated by solar heat and flows back to the heat storage tank 1 through the downcomer pipe 17. By repeating this circulation, the heat medium B in the heat storage tank 1 is heated. Furthermore, the air in the heat collecting circuit 11 is vented from the automatic air vent valve 28, thereby allowing smooth circulation. On the other hand, the hot water supply pump 20 is operated by opening the hot water tap 19, and the heat medium B is guided from the outlet 2 to the supply path 7. At this time, the heating medium B for the tapped hot water is
The heat storage tank 1 is automatically replenished from the ball tap 13, but in order to prevent the supplied low-temperature heat medium B from mixing with the high-temperature heat medium B in the tank, the heat medium B is stored in the separator tube 24. It is led to the lower layer of tank 1. Since the outlet 2 is located in the small-diameter wall 9 portion, the amount of high-temperature heat medium remaining above the outlet 2 is significantly reduced. In addition, due to the inclined peripheral wall 10 on the lower side of the small diameter wall 9,
The high temperature heat medium B is smoothly pushed up by the supplementary heat medium B, and the high temperature heat medium B is collected on the small diameter wall 9.
