| 摘要 |
The present invention relates to a solar thermal system which has improved use efficiency, enables heat acquired in a heat-collecting unit to be quickly used for a heating and hot water supply load, and can be operated in a stable manner. The solar thermal system comprises: a solar heat collector; a heat storage tank that contains heating water; a press sensor sensing the pressure in a heat storage pipe and a circulation pump pressing and circulating a heat medium that are connected to the heat storage pipe. The solar thermal system further comprises a heat medium supplementary water tank and an auxiliary boiler that has a heating water outlet connected to a heating water supply pipe of the heat storage tank through a 3-way valve for controlling the heating water supply. |
