When the second temperature sensor 6-2 detects that the temperature of the medium of the liquid supply pipeline reaches 95 ℃ of the upper limit, the system intelligent controller 7 closes the normally open electromagnetic valve 6-31 in a hot-running mode, simultaneously opens the normally closed electromagnetic valve 6-34, a fan of the cooler 6-32 cools the medium passing through the cooler 6-32, when the second temperature sensor receiver 6-2 reaches 80 ℃ of the lower limit, the normally open electromagnetic valve 6-31 is opened, the normally closed electromagnetic valve 6-34 is closed, and the cooler 6-32 stops cooling.

The working principle and the process of the embodiment are as follows: the solar heat collector module 1 drives the circulating pumps 6-7 to push heat-absorbing media to flow through the liquid supply pipe network 2 by using a temperature difference control principle through the system intelligent controller 7. When the first temperature sensor 2-1 and the third temperature sensor 6-4 reach the upper limit of the set temperature difference (for example, 95 degrees), the system intelligent controller 7 starts the circulating pump 6-7, and the medium flows through the liquid supply pipe network 2 after entering the solar heat collector module 1 and enters the special solar expansion tank 3 of the system; when the set temperature difference lower limit is reached (for example, 89 ℃), the circulating pump 6-7 is closed;
when the sunlight is strong, high-temperature media pass through the over-temperature cooling device 1-3, when the first temperature sensor 2-1 detects that the temperature of the media in the liquid supply pipe network 2 reaches the upper limit of 95 ℃, the system intelligent controller 7 closes the normally open electromagnetic valves 6-31, simultaneously opens the normally closed electromagnetic valves 6-34, the fans of the coolers 6-32 and the circulating pump 6-7 to cool the media passing through the coolers 6-32, when the first temperature sensor 2-1 reaches the lower limit of 80 ℃, the normally open electromagnetic valves 6-31 are opened, the normally closed electromagnetic valves 6-34, the fans of the coolers 6-32 and the circulating pump 6-7 are closed, and the coolers 6-32 stop cooling the media to finish the over-temperature protection function.
The circulating pump 5-2 is controlled by the system intelligent controller 7 and runs periodically, and the pushing medium sequentially passes through the system special solar expansion tank 3, the heat storage and liquid supply pipe network 4, the household heat exchange device 4-2 and the heat storage and liquid return pipe network 5 to run circularly. The system-dedicated solar expansion tank 3 in the embodiment adopts an expansion tank disclosed in CN211119600U in the prior art.

When no sunlight is irradiated, the household controller 4-2 heats the water in the pressure-bearing heat exchange water tank 4-24 to the use temperature by controlling the electric heating pipe 4-28. At the moment, the fifth temperature sensors 4-25 reach the temperature higher than the fourth temperature sensors 4-25 in the heat storage and liquid supply pipe network 4, and high-temperature hot water in the pressure-bearing heat exchange water tanks 4-24 is not transferred to the liquid supply pipe network 4 and the liquid return pipe network 5 due to the normally closed solenoid valves 4-23, so that heat loss is reduced, heat in the household pressure-bearing heat exchange water tanks 4-24 does not flow back, and heat reverse transfer is solved.
