Description

Technical Field

[0001] The present disclosure belongs to the field of heating valve control, and more specifically, to a heating valve control method and device. Background Art

[0002] In cold seasons, the heating system provides heat to buildings and keeps the indoor temperature within a suitable range. Maintaining a certain indoor temperature can prevent the water supply pipes and fire protection pipes in the building from freezing and rupturing due to low temperatures. In winter, if there is no heating, the water in the water pipes will expand after freezing, which may burst the pipes, causing leaks and other accidents, resulting in property losses.

[0003] Among them, the heating valve is used to control the water flow in the heating system. By adjusting the degree of opening of the valve, the water flow can be accurately controlled to avoid overheating or overcooling, thereby achieving effective control of the temperature of the heating system. The valve also plays a role in balancing the water pressure in the heating system, which can keep the water flow balanced in the system, avoid high or low pressure in the system, and ensure the stable operation of the heating system. Nowadays, the control of the heating valve is not precise enough. Since the temperature increase has a delay, the heating valve is usually controlled and adjusted only after the indoor temperature drops, making it difficult to maintain the stability of the indoor temperature. At the same time, when foreign objects appear in the pipe, it is difficult to detect.

[0004] It can be seen that an accurate and reliable heating valve control method is urgently needed. Summary of the invention

[0024] The first area is the heating area, the second area is the non-heating area adjacent to the heating area, the third area is each area within the first area, the first valve is the valve of the main pipeline for heating the first area, the second valve is the valve of the branch pipeline for heating the third area, the first water pump is the water pump that provides the flow rate for the heating fluid in the main pipeline, and the second water pump is the water pump that provides the flow rate for the heating fluid in the branch pipeline.

[0025] Please refer to Figure 2 , Figure 2 A flow chart of a heating valve control method provided in an embodiment of the present disclosure, the method comprising:

[0026] S101: Acquire a first environmental parameter and a second environmental parameter, wherein the first environmental parameter is an environmental parameter of a first area, and the second environmental parameter is an environmental parameter of a second area, wherein the first area is a heating area, and the second area is a non-heating area adjacent to the first area.

[0027] In this embodiment, the first environmental parameter may be the temperature of the first area, the first area may be a heating area, the second environmental parameter may be the temperature of the second area, the second area may be a non-heating area adjacent to the first area, the first environmental parameter may be obtained through a temperature sensor, and the second environmental parameter may be obtained through a temperature sensor.

[0028] For example, the first area is indoors of a residential room, the first environmental parameter is the temperature indoors of the residential room, the second area is outdoors of the residential room, the second environmental parameter is the temperature outdoors of the residential room. The indoor temperature of the residential room is obtained by the first temperature sensor, and the outdoor temperature of the residential room is obtained by the second temperature sensor.

[0029] S102: Determine a target adjustment parameter based on the first environmental parameter and the second environmental parameter, and adjust the opening degree of a target valve according to the target adjustment parameter, where the target valve is a pipeline valve for supplying heat to the first area.

[0030] In this embodiment, the first environmental parameter may be the temperature of the first area, which may be a heating area; the second environmental parameter may be the temperature of the second area, which may be a non-heating area adjacent to the first area; the target adjustment parameter is a parameter for controlling the degree of opening of the target valve, which is a pipeline valve for supplying heat to the heating area.

[0031] The target valve can be divided into a main pipeline valve and a branch pipeline valve. The main pipeline valve is a valve for supplying heat to the first area, and the second valve is a valve for supplying heat to each area within the first area. The target adjustment parameter can be determined based on the difference between the first environmental parameter and the second environmental parameter.

[0032] The opening degree of the target valve is adjusted according to the target adjustment parameter and can be adjusted to the parameter value of the target adjustment parameter. The opening degree can be any value from 0 to 10.

[0033] In response to the difference between the first environmental parameter and the second environmental parameter being greater than the first temperature threshold, the target adjustment parameter is controlled to be adjusted using a first linear formula, and the opening degree of the target valve is adjusted according to the target adjustment parameter. The first linear formula is:

[0034] in is the output regulation amount, is the first slope, is the difference between the first environmental parameter and the second environmental parameter;

[0035] In response to the difference between the first environmental parameter and the second environmental parameter being greater than the second temperature threshold, the target adjustment parameter is controlled to be adjusted using a second linear formula, and the opening degree of the target valve is adjusted according to the target adjustment parameter. The second linear formula is:

[0036] in is the output regulation amount, is the second slope, is the difference between the first environmental parameter and the second environmental parameter;

[0037] The first temperature threshold is smaller than the second temperature threshold, the first temperature threshold and the second temperature threshold can be manually set based on experience, and the slope of the first linear formula is smaller than the slope of the second linear formula.

[0038] For example, the first area is the indoor area of ​​water plant A, and the second area is the outdoor area of ​​water plant A. The indoor temperature of water plant A is 20°C (the first environmental parameter) and the outdoor temperature is -5°C (the second environmental parameter) obtained by the temperature sensor. The first temperature threshold is set to 20°C and the second temperature threshold is set to 27°C. At this time, the difference between the indoor temperature and the outdoor temperature of water plant A is 25, which is greater than the first temperature threshold. The first formula can be used to adjust the target adjustment parameter. The first slope of the first formula is It can be 0.2, is 25 (the difference between the first environmental parameter and the second environmental parameter). At this time, the adjustment amount output by the first formula is 5. The target adjustment parameter can be adjusted to 5 according to this adjustment amount. At this time, the opening degree of the first valve and the second valve is controlled to be 5.

[0039] After a period of time, the indoor temperature of Water Plant A is 22°C and the outdoor temperature is -8°C. At this time, the difference between the indoor temperature and the outdoor temperature of Water Plant A is 30, which is greater than the second temperature threshold. The second formula can be used to adjust the target adjustment parameter. The second slope of the second formula is It can be 0.25, is 30 (the difference between the first environmental parameter and the second environmental parameter). At this time, the adjustment amount output by the first formula is 7.5. The target adjustment parameter can be adjusted to 7.5 according to the adjustment amount. At this time, the opening degree of the first valve and the second valve is controlled to be 7.5.

[0040] From the above, it can be concluded that the system can more accurately understand the relationship between heating demand and external environmental conditions by acquiring and comparing the environmental parameters of the first area (heating area) and the second area (non-heating area) in real time. The target adjustment parameters formulated based on these parameters can adjust the opening degree of the target valve (i.e., the valve of the heating pipe), thereby realizing heating on demand, avoiding overheating or insufficient heating, and significantly improving the precision of heating valve control; the present disclosure accurately controls the temperature of the heating area, making the indoor temperature more stable and comfortable, avoiding indoor temperature fluctuations caused by uneven heating or excessive heating, improving the user's living experience and quality of life, and significantly improving the precision and reliability of heating valve control.

[0041] In one embodiment of the present disclosure, the first environmental parameter includes: the current ambient temperature of the first area;

[0045] determining a regulating parameter of the first valve based on a current ambient temperature of the first zone and a current ambient temperature of the second zone;

[0046] The adjustment parameter of the second valve is determined based on the current ambient temperature of the first zone and the predicted ambient temperature of the second zone.

[0047] In this embodiment, the first environmental parameter may be the current ambient temperature of the first area, the first area may be the indoor heating area, the second environmental parameter may be the current ambient temperature and the predicted ambient temperature of the second area, the second area may be a non-heating area adjacent to the heating area, the current ambient temperature of the first area and the current ambient temperature of the second area may be obtained through a temperature sensor, and the predicted temperature of the second area is the ambient temperature at a preset first time period, and the first time period may be manually set based on the historical time required for the temperature of the heating area to rise.

[0048] The predicted ambient temperature of the second area may be obtained based on meteorological data released by the Meteorological Bureau, or may be predicted based on a neural network model, where the neural network is a neural network that has been trained with historical temperature change information and time information.

[0049] The target valve includes a first valve and a second valve. The first valve is a main pipeline valve for supplying heat to the first area, and the second valve is a branch pipeline valve for supplying heat to various areas of the first area. The rated flow of the first valve is greater than the rated flow of the second valve. There are multiple second valves, and each second valve corresponds to a different branch pipeline and a different area in the first area.

[0050] In response to the difference between the current ambient temperature of the first area and the current ambient temperature of the second area being greater than the first temperature threshold, the adjustment parameter of the first valve is controlled to be adjusted according to the first linear formula, and the opening degree of the first valve is adjusted according to the adjustment parameter of the first valve, and the first linear formula is:

[0051] in is the output regulation amount, is the first slope, is the difference between the current ambient temperature of the first area and the current ambient temperature of the second area;

[0052] In response to the difference between the current ambient temperature of the first area and the current ambient temperature of the second area being greater than the second temperature threshold, the first adjustment parameter is controlled to be adjusted using a second linear formula, and the opening degree of the first valve is adjusted according to the first adjustment parameter, and the second linear formula is:

[0053] in is the output regulation amount, is the second slope, is the difference between the current ambient temperature of the first area and the current ambient temperature of the second area;

[0054] The first temperature threshold is smaller than the second temperature threshold, the first temperature threshold and the second temperature threshold can be manually set based on experience, and the slope of the first linear formula is smaller than the slope of the second linear formula;

[0055] In response to the difference between the current ambient temperature of the first area and the predicted ambient temperature of the second area being greater than the third temperature threshold, the adjustment parameter of the second valve is controlled to be adjusted according to the third linear formula, and the opening degree of the second valve is adjusted according to the adjustment parameter of the second valve, and the third linear formula is:

[0056] in is the output regulation amount, is the third slope, is the difference between the current ambient temperature of the first area and the predicted ambient temperature of the second area;

[0057] In response to the difference between the current ambient temperature of the first area and the predicted ambient temperature of the second area being greater than a fourth temperature threshold, the second adjustment parameter is controlled to be adjusted using a fourth linear formula, and the opening degree of the second valve is adjusted according to the second adjustment parameter, the fourth linear formula being:

[0058] in is the output regulation amount, is the fourth slope, is the difference between the current ambient temperature of the first area and the predicted ambient temperature of the second area;

[0059] The third temperature threshold is smaller than the fourth temperature threshold, the third temperature threshold and the fourth temperature threshold can be set manually based on experience, and the slope of the third linear formula is smaller than the slope of the fourth linear formula.

[0060] For example, considering the impact of outside temperature on indoor temperature, two thresholds are set. The lower the outdoor temperature, the more sufficient the indoor heating should be to ensure that the indoor temperature is in a comfortable environment.

[0061] The first area is the indoor area of ​​resident house B, and the second area is the outdoor area of ​​resident house B. The indoor temperature of resident house B is 20℃ (the current ambient temperature of the first area) and the outdoor temperature is -5℃ (the current ambient temperature of the second area) obtained by the temperature sensor. The first temperature threshold is set to 20℃ and the second temperature threshold is set to 27℃. At this time, the difference between the indoor temperature and the outdoor temperature of resident house B is 25, which is greater than the first temperature threshold. The first formula can be used to adjust the target adjustment parameter. The first slope of the first formula It can be 0.2, is 25 (the difference between the first environmental parameter and the second environmental parameter). At this time, the adjustment amount output by the first formula is 5. The target adjustment parameter can be adjusted to 5 according to this adjustment amount. At this time, the opening degree of the first valve and the second valve is controlled to be 5.

[0062] After a period of time, the indoor temperature of resident room B is 22°C and the outdoor temperature is -8°C. At this time, the difference between the indoor temperature and the outdoor temperature of resident room B is 30, which is greater than the second temperature threshold. The second formula can be used to adjust the target adjustment parameter. The second slope of the second formula is It can be 0.25, is 30 (the difference between the first environmental parameter and the second environmental parameter). At this time, the adjustment amount output by the first formula is 7.5. The target adjustment parameter can be adjusted to 7.5 according to the adjustment amount. At this time, the opening degree of the first valve and the second valve is controlled to be 7.5.

[0063] Or, for example, taking into account the delayed nature of heating itself, the second valve in each zone can be controlled based on the future outdoor temperature, so that the indoor temperature can be stabilized to ensure a comfortable working temperature.

[0064] The first area is the indoor area of ​​resident house B, and the second area is the outdoor area of ​​resident house B. The indoor temperature of resident house B obtained by the temperature sensor is 20°C (the current ambient temperature of the first area), and the outdoor temperature is -10°C one hour later (the predicted ambient temperature of the second area). The first temperature threshold is set to 26°C, and the second temperature threshold is set to 31°C. At this time, the difference between the indoor temperature and the outdoor temperature of resident house B is 30, which is greater than the third temperature threshold. The third formula can be used to adjust the target adjustment parameter. The first slope of the third formula is It can be 0.2, is 30 (the difference between the current ambient temperature of the first area and the predicted ambient temperature of the second area). At this time, the adjustment amount output by the first formula is 6. The target adjustment parameter can be adjusted to 6 according to this adjustment amount. At this time, the opening degree of the second valve is controlled to be 6.

[0065] After a period of time, the indoor temperature of resident room B is 22°C and the outdoor temperature is -10°C. At this time, the difference between the indoor temperature and the outdoor temperature of resident room B is 32, which is greater than the fourth temperature threshold. The fourth formula can be used to adjust the target adjustment parameter. The fourth slope of the fourth formula is It can be 0.25, is 32 (the difference between the current ambient temperature of the first area and the predicted ambient temperature of the second area). At this time, the adjustment amount output by the fourth formula is 8. The target adjustment parameter can be adjusted to 8 according to this adjustment amount. At this time, the opening degree of the second valve is controlled to be 8.

[0066] It can be concluded from the above that by simultaneously considering the current ambient temperature of the first area and the current and predicted ambient temperature of the second area, the system can more accurately adjust the temperature difference between the two areas and avoid unnecessary energy waste. The present disclosure introduces the predicted ambient temperature as the basis for adjustment, so that the present disclosure can respond in advance, rather than waiting until the ambient temperature actually changes before making adjustments. This forward-looking adjustment method can significantly shorten the system response time and improve the comfort of the indoor environment. For example, if it is predicted that the second area is about to heat up, the system can adjust the opening degree of the second valve in advance to reduce temperature fluctuations, thereby improving the accuracy and comfort of heating.

[0067] In one embodiment of the present disclosure, the heating valve control method further includes:

[0068] respectively determining the heating demand of a plurality of third areas;

[0069] Determining an adjustment parameter of the second valve according to the heating demand of the plurality of third areas, and adjusting the opening degree of the second valve according to the adjustment parameter of the second valve;

[0070] The third area is a different area of ​​the first area;

[0071] The second valve is a branch pipe valve for supplying heating to the third zone.

[0072] In this embodiment, the third area may be a different area within the first area, and the heating demand of the third area may be preset.

[0073] Considering that different areas within a heating area have different heating demands, for example, for residential houses, the heating demands for balconies and storage rooms are relatively low, so the heating in these areas can be reduced or shut down. Some rooms are on the shady side, so the heating demands are greater, and vice versa. For some factory areas, the heat dissipation of some equipment rooms is sufficient to meet their own needs, so the heating can be reduced. The heating demand is artificially set.

[0074] Specifically, residential house C contains a master bedroom, a second bedroom, a storage room, a living room and a balcony. The heating demand of the master bedroom is set to 1, the heating demand of the second bedroom is 0.8, the heating demand of the storage room is 0.2, the heating demand of the living room is 0.9, and the heating demand of the balcony is 0.1. If the adjustment parameter of the second valve obtained based on the current ambient temperature of residential house C and the temperature outdoors one hour later is 8, then the opening degree of the second valve corresponding to the master bedroom is 1×8, which is 8. Similarly, the opening degree of the second valve corresponding to the second bedroom is 6.4, the opening degree of the second valve corresponding to the storage room is 1.6, the opening degree of the second valve corresponding to the living room is 7.2, and the opening degree of the second valve corresponding to the balcony is 0.8.

[0075] From the above, it can be concluded that by separately determining the heating demand of multiple third areas (i.e., different areas within the first area), the system of the present invention can implement more refined heating management. Different areas can obtain personalized heating services according to their actual heating needs, avoiding the same heating method, thereby improving the heating efficiency, reducing unnecessary waste of resources, and achieving the effect of saving energy.

[0076] In one embodiment of the present disclosure, the heating valve control method further includes:

[0077] Obtaining temperature change rates of multiple third areas and corresponding opening degrees of second valves, where the multiple third areas are different areas of the first area, there are multiple second valves, and the second valves are pipeline valves that supply heat to the third areas;

[0078] Based on the temperature change rates of the third regions and the corresponding opening degrees of the second valves and the historical temperature change rates of the third regions and the corresponding opening degrees of the second valves, it is determined whether there are foreign objects in the pipes of the third regions.

[0079] In this embodiment, the third region is a different region within the first region, and the temperature change rate of the third region can be calculated by the first temperature change rate formula. The first temperature change rate formula is: ,in is the temperature change rate, is the temperature change, is the change in time, It can be obtained through the temperature sensor. Can be obtained through the timer.

[0080] Whether there is foreign matter in the corresponding branch pipe can be determined based on the historical temperature change rate of the third area corresponding to the second valve opening degree and the current temperature change rate of the third area corresponding to the second valve opening degree.

[0081] In response to the difference between the temperature change rate of the third area corresponding to the opening degree of the second valve and the temperature change rate of the third area corresponding to the opening degree of the second valve in history being greater than the first foreign matter threshold, it is determined that a foreign matter exists in the corresponding branch pipeline;

[0082] In response to the difference between the temperature change rate of the third area corresponding to the opening degree of the second valve and the temperature change rate of the third area corresponding to the opening degree of the second valve in history being less than the first foreign matter threshold, it is determined that no foreign matter exists in the corresponding branch pipeline;

[0083] The first foreign body threshold may be set manually based on experience.

[0084] For example, the first foreign object threshold is set to 0.2. In a residential house D, the opening degree of the second valve of the current bedroom is 5, and the temperature change rate of the current bedroom is 0.3℃ / h (degrees Celsius / hour). In the historical records of this residential house D, when the opening degree of the second valve corresponding to the bedroom is 5, the corresponding temperature change rate is 1℃ / h, and the difference is 0.7. 0.7 is greater than 0.2, so there is a foreign object in the branch pipe corresponding to the bedroom.

[0085] From the above, it can be concluded that the present invention can detect possible foreign matter in the pipeline in advance by real-time monitoring of the temperature change rate of multiple third areas and the opening degree of the corresponding second valves, and comparing and analyzing with historical data. The above-mentioned early warning mechanism helps to take timely measures when the problem actually occurs, preventing continuous heating failures caused by pipeline blockage or foreign matter, thereby improving the stability and reliability of the heating system.

[0086] In one embodiment of the present disclosure, the heating valve control method further includes:

[0087] In response to the difference between the temperature change rate of the third area corresponding to the historical opening degree of the second valve and the temperature change rate of the third area corresponding to the current opening degree of the second valve being less than a first threshold, controlling the corresponding second valve to increase the opening degree, and controlling other second valves to decrease the opening degrees;

[0088] In response to the difference between the temperature change rate of the third area corresponding to the historical opening degree of the second valve and the temperature change rate of the third area corresponding to the current opening degree of the second valve being greater than the first threshold, an alarm signal is sent to the terminal device.

[0089] In one embodiment of the present disclosure, the heating valve control method further includes:

[0090] Obtain pressure values ​​of multiple third-area pipelines;

[0091] In response to the pressure value of the pipeline in the third area being greater than the corresponding second threshold value, controlling the corresponding second valve to reduce the opening degree, and controlling the other second valves to increase the opening degree;

[0092] In response to the pressure values ​​of the plurality of third-area pipelines being greater than their corresponding second thresholds, the first valve is controlled to reduce its opening degree.

[0093] In this embodiment, the first threshold value can be set manually based on experience. Considering the presence of foreign matter in the pipeline, if the temperature change rate is not much different, that is, it does not exceed the first threshold value, then the foreign matter is small, and you can try to increase the opening degree of the second valve of the corresponding branch pipeline and reduce the opening degree of the second valve of other branch pipelines, and try to flush away the foreign matter by increasing the water flow pressure. However, if the temperature change rate is different, that is, it exceeds the first threshold value, it is judged that the foreign matter is large, and increasing the water flow pressure may carry away the foreign matter and cause the pipeline to rupture, or it may fail to flush away the foreign matter. Therefore, at this time, the method of increasing the flow rate is no longer tried, and an alarm is directly sent to the terminal device, indicating that the temperature change in a certain area is abnormal, and there may be foreign matter, please deal with it in time.

[0094] The second threshold can be set manually based on experience. If the pressure reaches the maximum value (the second threshold) when trying to increase the water flow rate to flush away foreign matter, the corresponding second valve is controlled to reduce the degree of opening, and the other valves are increased to reduce the pressure of the branch pipeline. If both are greater than, the first valve of the main pipeline is adjusted to reduce the degree of opening.

[0095] In response to controlling the corresponding second valve to increase the opening degree and controlling the other second valves to decrease the opening degree for a second time period, controlling the second valve to restore the original opening degree and controlling the other second valves to restore the original opening degree, wherein the second time period may be manually set based on experience;

[0096] In response to controlling the above-mentioned second valve to restore the original opening degree and controlling the above-mentioned other second valves to restore the original opening degree, when the difference between the temperature change rate of the third area corresponding to the historical opening degree of the second valve and the temperature change rate of the third area corresponding to the current opening degree of the second valve is still less than the first threshold, an alarm signal is sent to the terminal device, indicating that the temperature change in a certain area is abnormal and foreign matter may be present, please deal with it in time.

[0097] For example, when it is determined that there is foreign matter in the heating pipe corresponding to the living room of residential house E, the first threshold is 0.5, the second threshold is 1 MPa (megapascal), the opening degree of the second valve in the current living room of residential house E is 6, and the current temperature change rate of the bedroom is 0.4℃ / h. In the historical records of this residential house E, when the opening degree of the second valve corresponding to the living room is 6, the corresponding temperature change rate is 0.7℃ / h, and the difference is 0.3. 0.3 is less than 0.5, so there is foreign matter in the branch pipe corresponding to the bedroom and the foreign matter is relatively small. At this time, the second valve corresponding to the living room is controlled to increase the opening degree, and the second valves corresponding to other areas (bedrooms, kitchens, etc.) are controlled to decrease the opening degree, so that the water flow rate in the heating pipe of the living room is increased to try to flush away the foreign matter.

[0098] The second duration is set to 5 minutes. After the above process of increasing the opening degree of the second valve corresponding to the living room and reducing the opening degree of the second valve corresponding to other areas lasts for 5 minutes, the second valve corresponding to the living room is controlled to restore the original opening degree, and the second valves corresponding to other areas are controlled to restore the original opening degree. At this time, if the difference between the temperature change rate corresponding to the historical opening degree of the second valve in the living room and the temperature change rate corresponding to the current opening degree of the second valve in the living room is still less than the first threshold, a Beijing signal is sent to the terminal device, prompting that there may be foreign matter in the pipe corresponding to the living room, please deal with it in time.

[0099] During this process, the pressure value of each pipeline is monitored in real time. If the pressure value of a pipeline is greater than 1MPa, the second valve corresponding to the pipeline is immediately controlled to reduce the opening degree, and other second valves are controlled to increase the opening degree. If the pressure of all pipelines reaches the threshold due to other reasons, the first valve is controlled to reduce the opening degree.

[0100] From the above, it can be concluded that by comparing the temperature change rate of the third area corresponding to the historical and current opening degrees of the second valve, dynamic monitoring and adjustment of the heating effect is achieved. When the temperature change rate difference is greater than the first threshold, the system can identify possible abnormal conditions (such as pipeline blockage, equipment failure, etc.) and send an alarm signal to the terminal device in time. This helps operation and maintenance personnel to quickly locate the problem and take corresponding measures, reduce heating interruptions or temperature fluctuations caused by failures, and improve the precision and reliability of this method.

[0101] In one embodiment of the present disclosure, the heating valve control method further includes:

[0102] In response to a change in the opening degree of the first valve, controlling the rotation speed of the first water pump to change;

[0103] The first water pump is used to provide a flow rate for the heating fluid in the main pipeline, and the main pipeline is a pipeline for supplying heat to the first area.

[0104] In one embodiment of the present disclosure, the heating valve control method further includes:

[0105] In response to changes in the opening degrees of the plurality of second valves, the rotation speeds of the corresponding second water pumps are controlled to change;

[0106] The second water pump is used to provide a flow rate for the heating fluid in the branch pipes, and the branch pipes are pipes for supplying heat to a plurality of third areas.

[0107] In this embodiment, the first water pump is arranged in the opposite direction of the water flow of the first valve. When the opening degree of the first valve decreases, the rotation speed of the first water pump also decreases. When the opening degree of the first valve increases, the rotation speed of the first water pump also increases.

[0108] The second water pump is arranged in the opposite direction of the water flow of the second valve. When the opening degree of the second valve decreases, the rotation speed of the second water pump also decreases. When the opening degree of the second valve increases, the rotation speed of the second water pump also increases. There are multiple second water pumps, and the opening degree of each valve corresponds to the rotation speed of a gear of the water pump.

[0109] For example, when the opening degree of the first valve is 5, the speed gear number of the first water pump is also 5. When the opening degree of the first valve becomes 6, the speed gear number of the first water pump is also 6, so as to supply sufficient water flow and water flow speed, while reducing the water flow impact on the first valve, thereby extending the service life.

[0110] The opening degree of a second valve is 4, and the corresponding speed level of the second water pump is also 4. When the opening degree of the second valve becomes 7, the speed level of the second water pump is also 7, so as to supply sufficient water flow and water flow speed, and at the same time reduce the water flow impact on the second valve, thereby extending the service life.

[0111] From the above, it can be concluded that when the opening degree of the first valve or the second valve is changed, the corresponding rotation speed of the water pump is adjusted accordingly, thereby ensuring that the flow rate of the heating fluid in the heating pipe matches the heating demand, while reducing the impact of the water flow on the valve, extending the service life of the valve, and improving the precision and reliability of the heating valve control.
