[0002] Geothermal heating refers to the use of geothermal energy as the main heat source for heating. Geothermal energy has become the backbone of energy development.

[0003] In some parts of my country, geothermal energy has been used for heating and cooling, while in most areas, heating still uses radiators as heat release terminals, which has low thermal energy utilization rate. As people's living standards improve, the requirements for heating or cooling are getting higher and higher, and conventional heating can no longer meet people's needs. Since thermal energy is stable and is not affected by the weather, geothermal energy can provide stable heat, but the thermal energy temperature required by people is different in different seasons or even at different times of the day. Therefore, it is necessary to adjust the flow of the geothermal end in real time according to the needs of the user end to avoid excess thermal energy and waste of resources.

DETAILED DESCRIPTION

[0045] In order to make the purpose, technical solution, design method and advantages of the present invention clearer, the present invention is further described in detail by specific embodiments in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0046] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5The present invention provides a geothermal end flow regulation method based on user demand temperature, which is to control the flow opening of the first regulating valve 2 through a control device based on the user's current temperature and the predicted temperature of a unit time in the future, and to control the flow opening of the second regulating valve 9 through a control device to meet the user's demand temperature after comparing the detection result of the temperature sensor 9.5 with the user's demand temperature; the method comprises: a main controller 11 receives the current temperature and the predicted temperature of a unit time in the future, and obtains the user's demand temperature based on the current temperature and the predicted temperature; the main controller 11 responds to a first regulation signal and loads a first regulation mechanism according to the current temperature and the predicted temperature, and a judgment module 12 judges whether the first regulation mechanism meets the preset driving condition, and when it is determined that the first regulation mechanism meets the preset driving condition, the main controller 11 sends the first regulation mechanism to the first control component 13, and the first control component 13 drives the first regulating valve 2 based on the first regulation mechanism to store the heat of the first temperature value to the thermal energy storage box 7, and when it is determined that the first regulation mechanism does not meet the preset driving condition, the connection circuit between the main controller 11 and the first control component 13 is checked;

[0047] The main controller 11 responds to the second control signal according to the user's required temperature and loads the second control mechanism. Based on the second control mechanism, the judgment module 12 judges whether the second control mechanism meets the preset driving conditions. When it is determined that the second control mechanism meets the preset driving conditions, the main controller 11 sends the second control mechanism to the second control component 14. The second control component 14 drives the second regulating valve 9 based on the second control mechanism to meet the temperature requirement for the heat supply to the user end 10. When it is determined that the second control mechanism does not meet the preset driving conditions, the connection circuit between the main controller 11 and the second control component is checked.

[0048] Among them, the main controller 11 sends a handshake request to the first control component 13 and / or the second control component 14, the first control component 13 and / or the second control component 14 receive the handshake request and respond to the handshake request, and send the response information to the judgment module 12 and the main controller 11 at the same time, the judgment module 12 and the main controller 11 perform data synchronization, and the main controller 11 sends the first control mechanism and the second control mechanism to the first control component 13 and the second control component 14 respectively based on the response information. Through multiple handshake protocols, it is possible to quickly determine whether the control mechanism meets the driving conditions. During the implementation of the present invention, a warning device can be added. When the control mechanism does not meet the driving conditions, an alarm is issued to facilitate timely repairs by the staff.

[0049] In the above, the first control mechanism is to control the heat source flow rate of the first regulating valve 2 at different levels within multiple control ranges based on the change of the outdoor temperature of the user end 10. For example, when the outdoor temperature is low, it is expected to store more heat in the thermal energy storage box 7. At this time, it is necessary to increase the flow opening of the first regulating valve 2, such as Figure 4 As shown, the first motor 2.4 drives the rotating ball valve 2.5 to rotate so that the through hole 2.7 is on the same axis as the water outlet 2.2 and the water inlet 2.3. At this time, the opening of the first regulating valve 2 is the largest. On the contrary, when the outdoor temperature is high, the demand for heat energy at the user end 10 is reduced. In order to reasonably exploit the heat energy, the opening of the first flow valve 2 can be appropriately reduced. In addition, in the present invention, the first regulating mechanism is not only determined by the current temperature, but also by the predicted temperature within a certain time range. It is particularly suitable for areas with large temperature differences between morning and evening. Heat energy can be stored in advance according to the predicted temperature to avoid insufficient heat energy supply.

[0050] The second control mechanism is to control the flow opening of the second regulating valve 9 within multiple ranges based on the user demand temperature set by the user end 10, wherein the user demand temperature in the present invention can be set by collecting the user demand temperature by the user end, and the user demand temperature can also be estimated based on big data according to the current temperature and the predicted temperature within a certain period of time. Since the present invention is a centralized heating for groups, in order to simplify data collection, the user demand temperature can be quickly determined through the latter to ensure the needs of most people. In addition, a temperature sensor 9.5 is also set inside the second regulating valve 9. During the mixing process of cold energy and heat energy, the temperature inside the second regulating valve 9 is measured in real time, and the measurement result is compared with the user demand temperature, so as to regulate the second regulating valve 9 in real time, such as Figure 6-8 As shown, when the temperature measured by the temperature sensor 9.5 is lower than the user's required temperature, the second motor 18 drives the connecting rod 16 to rotate, so that the toggle rod 15 slides in the groove 9.6, thereby swinging the movable plate 9.4 to the position shown in FIG. Figure 6 The first interface 9.1 is rotated in the direction shown, so that the opening of the first interface 9.1 increases while the opening of the second interface 9.2 decreases. On the contrary, when the temperature measured by the temperature sensor 9.5 is higher than the user's required temperature, the second motor 18 drives the connecting rod 16 to rotate, so that the toggle rod 15 slides in the groove 9.6, and then the movable plate 9.4 moves in the direction shown. Figure 7 Rotating in the direction shown reduces the opening of the first interface 9.1 and increases the opening of the second interface 9.2.
