[0002] Liquid and air dual-purpose solar thermal collection and heating system is a necessary system in solar energy. The heating system we usually use can only perform single air heating or liquid heating. And the single heating system we usually use will cause the system to overheat due to the external temperature being too high, the water temperature being too high, or freezing and leakage due to the external temperature being too low. In addition, the heat collection effect fluctuates due to the different external temperatures. Therefore, in order to solve the above problems, we provide a liquid and air dual-purpose solar thermal collection and heating system. At the same time, it meets the needs of different application scenarios. Summary of the invention

[0016] In the present invention, the water inlet and outlet 7 is fixedly installed through an opening in the middle of one side of the bottom of the thermal insulation connection box 1, and the water inlet and outlet 7 is fixedly connected to the water pipe 6 through the thermal insulation connection box 1.

[0017] In the present invention, the air inlet 9 and the air outlet 11 are respectively fixedly connected to the air duct 2 through the openings on the surfaces of the two ends of the thermal insulation connection box 1. Ventilation holes are provided on both sides of the air duct 2. The sub-air duct 4 is fixedly connected to the air duct 2 through the ventilation holes. A separate air heating mode and a liquid and air mixed heating mode can be realized through the sub-air duct 4 and the air duct 2.

[0018] In the present invention, the water level temperature sensor 8 is fixedly installed through an opening on one side of the top of the thermal insulation connection box 1, and the water level temperature sensor 8 is connected to the water pipe 6 through the opening on one side of the top of the thermal insulation connection box 1. The water level temperature sensor 8 can help the user control the temperature and water level of the heating system during use, which is convenient to use.

[0019] In the present invention, the water inlet and outlet 7 is fixedly connected to the middle of one side of the bottom of the thermal insulation connection box 1, and the water inlet and outlet 7 is fixedly connected to the water pipe 6 through the opening in the middle of one side of the bottom of the thermal insulation connection box 1. The air heating mode, the water liquid heating mode and the mixed heating mode can be separated through the isolation plate inside the vacuum tube 3.

[0020] The working principle of the present invention is:

[0021] First, fill air into the air duct 2 through the air inlet 9, fill the air in the air duct 2 into the sub-air duct 4, inject water from the water inlet and outlet 7 into the insulation connection box 1 through the water pipe 6, determine the water volume and water temperature in the water pipe 6 through the water level temperature sensor 8, start air circulation through the air inlet 9 and the air outlet 11, start water circulation through the water inlet and outlet 7, then heat the air and water in the vacuum tube 3 through solar energy, and observe the water temperature in the vacuum tube 3 through the controller, and then increase or decrease the flow rate of the air inlet 9 and the flow rate of the water inlet and outlet 7 through the controller to ensure the temperature in the vacuum tube 3, and then use the heated water through the water inlet and outlet 7. When the system is overheated, the system is cooled down by increasing the air flow rate of the air inlet 9. When the temperature is prone to freezing and leakage in winter, the temperature in the air duct is maintained longer by reducing the operating efficiency of the air inlet 9 to avoid freezing and leakage. The heating mode of the system can be changed to a single gas heating mode, a single liquid heating mode, or a liquid and gas mixed heating mode through the controller. The exhaust fresh air inlet 10 is used as an exhaust outlet when the water system is collecting heat, and as a bypass fresh air inlet when the air is collecting heat.

[0022] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
