When the temperature of the heat exchange unit 4 is higher than 40 ℃, the solar energy heat supplementing sub-circulation system is started, the ground heat exchanger 7 sends water in the ground pipe into the heat exchange unit 4 through the ground circulating pump 6, the water returns to the ground after absorbing heat, and the steps are repeated so as to improve the soil temperature. When the temperature difference between the solar heat collector 1 and the heat exchange unit 4 is less than 3 ℃, a circulating pump of the heat collection system is closed; when the water temperature of the heat exchange unit 4 is lower than 15 ℃, the solar energy heat supplementing sub-circulation system is stopped; and when the difference between the outlet water temperature of the heat exchange unit 4 and the inlet water temperature of the buried pipe at the heat exchange unit 4 is less than 5 ℃, closing the solar energy heat supplementing sub-circulation system.
In the heating season, the system runs a solar energy-geothermal energy heat supply sub-circulation system, a solar energy heat supply sub-circulation system and a ground source heat pump heat supply sub-circulation system. When the temperature difference between the outlet temperature and the heat exchange unit 4 is more than 10 ℃, the heat collection system circulating pump 2 is started, the solar heat collector 1 collects solar energy, and heat is transferred to the heat exchange unit 4 through the heat collection system circulating pump 2; and when the temperature difference between the outlet temperature of the solar heat collector 1 and the temperature difference between the heat exchange units 4 is less than 3 ℃, stopping the circulating pump 2 of the heat collecting system. When the temperature of the heat exchange unit 4 is more than or equal to 40 ℃, the solar heat supply sub-circulation system is started, the side inlet and outlet pipe valve 20 of the condenser 25 of the ground source heat pump host 5 is opened, and the user heat supply circulation pump 8 sends hot water after heat exchange of the heat exchange unit 4 into the energy utilization unit 11. When the water temperature of the heat exchange unit 4 is higher than 15 ℃ and lower than 40 ℃, the solar energy heat supply sub-circulation system stops, the solar energy geothermal energy heat supply sub-circulation system is started, the inter-pipe valve 20 is closed on the side of the condenser 25 of the ground source heat pump host 5 and on the side of the water outlet pipe, the energy using unit 11 returns water to pass through the heat exchange unit 4 and then enter the side of the condenser 25 of the ground source heat pump host 5, and after the energy using unit is heated, the user is supplied with heat through the user heat supply circulation pump 8. When the water temperature of the heat exchange unit 4 is less than or equal to 15 ℃, the solar energy-geothermal energy heat supply self-circulation system is closed, the ground source heat pump heat supply sub-circulation system is opened, the valve 20 leading the energy utilization unit to the heat exchange unit 4 is closed, the electromagnetic valve 13 leading the energy utilization unit 11 to the inlet of the condenser is opened, the valve 20 between the condenser 25 side and the water outlet pipe of the ground source heat pump host 5 is closed, the energy utilization unit 11 returns water to enter the condenser 25 side of the ground source heat pump host 5, and after the water is heated, the user is heated by the user heating circulation pump 8.

Therefore, the utility model avoids the complex operation mode among a plurality of heat cycle systems, divides the operation period into the heating season and the non-heating season, and specifically comprises 4 cycles: the system comprises a solar energy-geothermal energy heat collecting sub-circulation system, a solar energy heat supplementing sub-circulation system, a solar energy heat supply sub-circulation system and a ground source heat supply sub-circulation system. There are 4 operating conditions all the year round: solar heat collection and solar heat compensation, solar heat collection and solar heat supply, solar heat collection and solar geothermal energy heat supply, and solar heat collection and ground source heat pump heat supply.

In the heating season or the non-heating season, the temperature data measured by the temperature sensor 12 is transmitted to the data receiving module of the terminal control unit 100, the operation condition is determined through the analysis of the data processing module and the data judging module, a control instruction is generated at the data output module of the terminal control unit 100 and is sent to the execution unit of the renewable energy open type coupling heating system, namely the valve 20, the electromagnetic valve 13, the heat collecting system circulating pump 2, the buried pipe circulating pump 6 and the user heating circulating pump, and the control, the on-off or the on-off of the execution unit is carried out.
