As shown in fig. 1, the present invention provides a preferred solar heating system capable of intelligently storing heat, which comprises a solar heat collection module 7, a heat storage water tank 5, an air source heat pump 2, an auxiliary heating circulating pump 1, a solar circulating pump 6, a user side circulating pump 3 and a user side 4, wherein one pipeline of the solar heat collection module 7 is communicated with the heat storage water tank 5 through the solar circulating pump 6, and the other pipeline of the solar heat collection module 7 also returns to the heat storage water tank 5; one end of an air source heat pump 2 is directly connected to the heat storage water tank 5, and the other end of the air source heat pump is connected to a water return pipeline of a solar heat collection module 7 through an auxiliary heating circulating pump 1 and is communicated to the heat storage water tank 5; in the return water pipeline of the solar heat collection module 7, an interface leading to the user side 4 is arranged, and the circulating working medium enters the user side 4 through the interface and the user side circulating pump 3, releases heat and then returns to the heat storage water tank 5.
When the heat energy generated by the solar heat collection module 7 meets the heat supply requirement, the solar circulating pump 6 is started to drive the circulating working medium from the heat storage water tank to perform heating circulation. When the user side 4 needs to supply heat, the user side circulating pump 3 and the solar circulating pump 6 are started simultaneously, the circulating working medium which is pumped out of the solar heat collecting module 7 enters the user side to be discharged, and then returns to the heat storage water tank 5, so that the process of solar heat supply is completed.
In the process, when the user terminal 4 reaches the heat supply temperature and does not need to supply heat any more, the user terminal circulating pump 3 is powered off, the solar circulating pump 6 judges the working state according to the temperature difference between the solar heat collecting module 7 and the heat storage water tank 5, and the heat energy generated by the solar heat collecting module 7 is gradually brought into the heat storage water tank 5, so that the heat storage process of solar energy is completed.
