[0049] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art. It should be noted that, in the absence of conflict, the embodiments of the present invention and the features described in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0050] With the development of the global economy, the consumption of traditional fossil energy (such as coal, oil and natural gas) is accelerating. These energy sources are not only non-renewable, but also produce a large amount of greenhouse gases such as carbon dioxide and methane during their combustion, leading to global warming. The energy crisis has prompted people to look for sustainable alternative energy sources. As an almost inexhaustible and clean energy source, the development and utilization of solar energy has received widespread attention. Solar thermal collection technology is an effective way to generate heat energy using solar energy. It can greatly alleviate the tight energy supply situation and reduce the negative impact on the environment.

[0051] Solar thermal collection technology is a key technology for converting solar energy into thermal energy and utilizing it. However, the existing solar thermal collection systems still have many shortcomings in terms of thermal collection efficiency, thermal energy storage and transmission, system stability, and adaptability to ambient temperature changes, and need further improvement and optimization.

[0052] Therefore, it is necessary to design a solar energy-based thermal collection system and method to improve the solar energy collection efficiency, achieve stable and efficient heat energy supply, and be able to flexibly and automatically adjust the system working state according to environmental or temperature changes to achieve efficient utilization and storage of thermal energy.

[0053] Reference Figure 1 , in some embodiments of the present application, a solar energy-based heat collection system includes: a solar energy heat collection module, a heat exchange module, a heat storage module and a control module;

[0054] Specifically, the solar thermal collection module is used to convert solar energy into thermal energy. The solar thermal collection module is composed of a plurality of high-efficiency solar thermal collectors, which adopt a flat plate or vacuum tube structure, and are coated with a solar selective coating with a high absorption rate. The high-efficiency solar thermal collectors are installed on a south-facing inclined surface.

[0055] It is understandable that the solar selective coating with high absorptivity enables the solar collector to effectively absorb solar energy and convert it into thermal energy. The solar collector is installed on a south-facing inclined surface to maximize the reception of solar radiation, thereby improving the utilization rate of solar energy.

[0056] Specifically, the heat exchange module is used to transfer the heat energy converted by the solar thermal collection module to the heat storage module, and the heat storage module is used to store the heat energy. The heat exchange module is connected to the solar thermal collection module and the heat storage module through its internal circulation pipeline. The heat exchange module transfers the heat energy converted by the solar thermal collection module to the heat storage module for storage. When the heat user needs heat energy, the heat exchange module transfers the heat energy stored in the heat storage module to the heat user.

[0057] It can be understood that the heat storage module can store excess heat energy when solar energy is sufficient, and release heat energy when solar energy is insufficient or there is no solar radiation, thereby ensuring the continuity of heat energy supply.

[0058] Specifically, the control module is used to monitor the temperature of the solar thermal collection module and the temperature of the heat storage module in the heat collection system in real time. The control module controls the start and stop of the heat exchange module according to the temperature of the solar thermal collection module and the preset working temperature range of the solar thermal collection module; and controls the start and stop of the heat exchange module according to the temperature of the heat storage module and the preset working temperature range of the heat storage module.

[0059] Specifically, the control module adjusts the temperature of the solar thermal collection module and the heat storage module according to the real-time collected temperature of the solar thermal collection module and the heat storage module and the preset operating temperature range of the solar thermal collection module and the heat storage module, so that the thermal collection system is at the optimal temperature, thereby improving the thermal collection efficiency and solar energy utilization rate of the thermal collection system.

[0060] It is understandable that the control module can adjust the working state of each module of the heat collection system according to the change of ambient temperature, realize the efficient collection of solar energy and the efficient use and storage of thermal energy, thereby reducing the dependence on traditional energy, helping to reduce carbon emissions, and having good environmental benefits and economy.

[0061] In some embodiments of the present application, the control module controls the start and stop of the heat exchange module according to the temperature of the solar thermal collection module and the preset working temperature range of the solar thermal collection module, including: if the temperature of the solar thermal collection module is higher than the preset working temperature range of the solar thermal collection module, controlling the heat exchange module to start and perform a thermal cycle process; if the temperature of the solar thermal collection module is lower than the preset working temperature range of the solar thermal collection module, controlling the heat exchange module to stop.

[0062] Specifically, when the temperature of the solar thermal collection module exceeds the operating temperature range, the solar thermal collection module stops collecting heat, and the control module controls the heat exchange module to start, transferring the solar thermal collection module to the heat storage module to perform a thermal cycle. Conversely, when the temperature of the solar thermal collection module is lower than the operating temperature range, the control module controls the heat exchange module to stop the thermal cycle, and controls the solar thermal collection module to collect solar energy and convert thermal energy.

[0063] It can be understood that the preset working temperature range of the solar thermal collection module is the optimal working temperature range of the solar thermal collection module. When the temperature of the solar thermal collection module is lower than the preset working temperature range, the solar thermal collection module starts to work, collects solar energy and converts it into thermal energy. When the temperature of the solar thermal collection module is higher than the preset working temperature range, the solar thermal collection module stops working and controls the solar thermal collection module to be in the optimal working temperature range, so as to improve the efficiency of solar energy collection and thermal energy conversion.

[0064] In some embodiments of the present application, the control module controls the start and stop of the heat exchange module according to the temperature of the solar thermal collection module and the preset operating temperature range of the solar thermal collection module, including: if the temperature of the solar thermal collection module is lower than the preset operating temperature range of the solar thermal collection module, adjusting the flow of the heat exchange module.

[0065] Specifically, when the temperature of the solar energy heat collection module is lower than the operating temperature range, the control module adjusts the temperature of the solar energy heat collection module by reducing the flow of the heat exchange module.

[0066] It is understandable that when the flow rate of the heat exchange module decreases, the heat energy released by the solar thermal collection module decreases, and the temperature drop rate of the solar thermal collection module slows down, which helps to regulate the temperature of the solar thermal collection module.

[0067] In some embodiments of the present application, the control module controls the start and stop of the heat exchange module according to the temperature of the heat storage module and the preset working temperature range of the heat storage module, including: if the temperature of the heat storage module is higher than the preset working temperature range of the heat storage module, controlling the heat exchange module to stop; if the temperature of the heat storage module is lower than the preset working temperature range of the heat storage module, controlling the heat exchange module to start and perform a thermal cycle process.

[0068] Specifically, when the temperature of the heat storage module exceeds the preset operating temperature range, the control module controls the heat exchange module to stop the thermal cycle process to reduce the heat energy input and prevent the heat storage module from overheating; conversely, when the temperature of the heat storage module is lower than the preset operating temperature range, the control module controls the heat exchange module to start and perform the thermal cycle process to transfer the heat energy of the solar thermal collection module to the heat storage module, so as to heat up the heat storage module and ensure that the temperature of the heat storage module is within the operating temperature range.

[0069] It can be understood that the preset operating temperature range of the heat storage module is the optimal operating range of the heat storage module, which ensures that the temperature of the heat storage module is within the optimal operating temperature range, thereby improving the storage efficiency and utilization rate of thermal energy.

[0070] In some embodiments of the present application, the control module controls the start and stop of the heat exchange module according to the temperature of the heat storage module and the preset working temperature range of the heat storage module, including:

[0071] If the temperature of the heat storage module is higher than the preset operating temperature range of the heat storage module, the flow of the heat exchange module is adjusted.

[0072] Specifically, when the temperature of the heat storage module is higher than a preset operating temperature range, the control module adjusts the temperature of the heat storage module by reducing the flow of the heat exchange module.

[0073] It is understandable that by reducing the flow of the heat exchange module, the input heat energy transferred from the heat exchange module to the heat storage module becomes smaller, and the temperature rise rate of the heat storage module slows down, which helps to regulate the temperature of the heat storage module.

[0074] In some embodiments of the present application, the control module is also used to preset the operating temperature range of the solar thermal collection module and the heat storage module.

[0075] In some embodiments of the present application, the heat exchange module is also used to transfer the thermal energy in the heat storage module to the heat user through the medium.

[0076] The heat exchange module also heats the medium returned by the heat user through the heat energy converted by the solar thermal collection module and then transfers it to the heat storage module.

[0077] Specifically, the heat exchange module transfers the heat energy in the heat storage module to the heat user through the heat transfer medium. The low-temperature medium returned by the heat user is heated by the heat energy converted by the solar thermal collection module through the heat exchange module. The heated low-temperature medium is then transferred to the heat storage module through the heat exchange module.

[0078] It can be understood that the heat exchange module, as a heat energy transfer module, transfers the heat energy of each module of the heat collection system to form a closed heat energy circulation loop.

[0079] In some embodiments of the present application, the control module also includes a temperature sensor, a light sensor, a flow sensor, a pressure sensor and a display; the heat exchange module includes a circulation pump, a pipeline and a valve.

[0080] Specifically, temperature sensors are respectively installed in the solar thermal collection module, heat storage module and heat user terminal to monitor the temperature of each part in real time; light sensors are used to monitor the intensity of solar radiation; flow sensors are used to monitor the medium flow in the heat exchange module circuit; pressure sensors are used to monitor the pressure changes of the system in real time; and the circulation pump adopts frequency conversion control to automatically adjust the flow according to the temperature changes of the solar thermal collection module and the heat storage module.

[0081] Specifically, the circulation pump is used to drive the circulation of the heat transfer medium.

[0082] Specifically, the control module also controls the operation of the circulation pump and the opening and closing of the valve according to the signals of the temperature sensor and the pressure sensor; it also adjusts the angle of the solar thermal collection module, regulates the charging and releasing of the heat storage module, and regulates the operation of the heat exchange module according to the data collected by all sensors.

[0083] It can be understood that when the intensity of solar radiation changes, the control module adjusts the angle of the solar thermal collection module according to the data collected by the light sensor in order to collect solar energy; when the temperature of the solar thermal collection module changes due to weather or environmental changes, the control module controls the operating state of the heat exchange module according to the data collected by the temperature sensor and the pressure sensor, and regulates the charging and releasing of the heat storage module.

[0084] Specifically, the display is used to display the operating status of the solar collector system and the parameters of each module in real time.

[0085] In some embodiments of the present application, a maximum temperature threshold and a minimum temperature threshold are set in the control module;

[0086] Specifically, the control module issues a high temperature alarm when the temperature of the solar thermal collection module and / or the heat storage module is greater than the maximum temperature threshold; the control module issues a low temperature alarm when the temperature of the solar thermal collection module and / or the heat storage module is lower than the minimum temperature threshold.

[0087] It is understandable that the control module can adjust the working state of the heat collection system according to changes in ambient temperature so as to achieve efficient utilization and storage of thermal energy.

[0088] In another preferred embodiment based on the above embodiment, refer to Figure 2 As shown, this embodiment provides a method based on a solar thermal collection system, comprising:

[0089] Real-time monitoring of the temperature of the solar thermal collection module and the temperature of the heat storage module in the thermal collection system; control of the start and stop of the heat exchange module according to the temperature of the solar thermal collection module and the preset working temperature range of the solar thermal collection module; and control of the start and stop of the heat exchange module according to the temperature of the heat storage module and the preset working temperature range of the heat storage module; when the solar thermal collection module is working, it converts solar energy into thermal energy; the heat exchange module transfers the thermal energy converted by the solar thermal collection module to the thermal storage module; the thermal storage module is used to store thermal energy.
