The invention provides a solar heat collection system, the system includes a solar heat collector, a hot water pipe network, a heat utilization device and a heat accumulator, a water supply pipe network and a return water pipe network are respectively provided with a third valve and a fourth valve, When the solar collector is running, the third valve and the fourth valve are opened; when the solar collector stops running or the solar energy is insufficient, the third valve and the fourth valve are closed, so that the heat accumulator becomes a new heat source, heat storage Heater and heat utilization device form a new thermal system. By arranging the heat accumulator, more solar energy can be stored in the heat accumulator, so as to satisfy the heat utilization under the condition of insufficient solar energy. |
