[0049] In the specific implementation manner of the present application, when it comes to any data related to an object, such as the data involved in the process of the object using an application program, when the embodiments of the present application are applied to a specific product or technology, the permission or consent of the object needs to be obtained, and the collection, use and processing of the relevant data need to comply with the relevant laws, regulations and standards of the relevant countries and regions. That is to say, in the embodiments of the present application, if any of the above data related to the object is involved, these data need to be obtained with the authorization and consent of the object and in compliance with the relevant laws, regulations and standards of the country and region.

[0050] To make the purpose, technical solution and advantages of the present application clearer, the following will further describe the embodiments of the present application in detail with reference to the accompanying drawings.

[0051] First, the technical terms involved in the present application will be introduced and explained:

[0052] Heat pump system: It is an efficient HVAC technology that can use a small amount of external energy to transfer heat, thereby providing heating and cooling for buildings. The working principle of the heat pump system is based on the refrigeration cycle, and it uses refrigerant as a medium to absorb and release heat.

[0053] The minimum gear of the water pump: It refers to the most basic operating state that the water pump can achieve. At this time, both the power and flow rate of the water pump are the lowest, which is suitable for application scenarios with small demands or only for maintaining basic functions. In the embodiments of the present application, adjusting the minimum gear is to ensure that the water flow state under the most basic state is normal.

[0054] In the prior art, the pipeline water resistance and the water pump head range in a newly installed water system are certain. When the total water resistance in the water system increases, such as changes in the circulating medium, increase in the concentration of antifreeze, accumulation of scale, water quality differences in different regions, and addition of terminals, etc., the applicability of the fixed flow rate of the water pump decreases, and there is a deviation between the target flow rate and the actual flow rate. It may occur that the actual circulating flow rate is too small, triggering the water flow switch to act, reporting a no-water-flow fault, and the unit frequently reports a no-water-flow fault, affecting the user experience.

[0055] The water pump adjustment method, device, water pump flow adjustment component, heat pump system, computer-readable storage medium, and computer program product provided by the present application aim to solve at least one of the above technical problems in the prior art.

[0056] In view of at least one of the above technical problems or areas for improvement existing in the related art, the present application proposes a water pump adjustment method, device, water pump flow adjustment component, heat pump system, computer-readable storage medium, and computer program product. The water pump adjustment method provided by this solution, by real-time monitoring the water flow state of the heat pump system pipeline, determines whether it is necessary to adjust the minimum gear of the water pump according to the water flow state. If adjustment is required, the target minimum gear is determined according to the real-time water flow temperature in the water flow state and the water pump is adjusted to complete the adjustment of the minimum water flow of the water pump. Real-time monitoring of the water flow state can timely detect water flow faults in the water circuit, and real-time acquisition of the real-time water flow temperature can timely determine the target minimum gear and adjust it when a pipeline fault occurs, effectively improving the adjustment efficiency of the water pump flow rate, avoiding frequent reporting of water flow faults, and improving the stability of the water flow.

[0057] Furthermore, when determining the target minimum gear based on the real-time water flow temperature, it is judged whether the water flow temperature crosses intervals. For the case where the temperature crosses intervals, based on the freezing point temperature of the fluid medium in the pipeline and the real-time water flow temperature, the target minimum gear corresponding to the interval is obtained. For the case where there is no interval crossing, the target minimum gear is determined according to the historical fault times. Accurately determining the corresponding minimum gear according to the water temperature partition can handle the water pump gear adjustment requirements in different temperature situations, adapt to water flow adjustments in different conditions, and make the water pump adjustment more flexible.

[0058] In addition, by obtaining the corresponding freezing point temperature for different fluid media, the water pump flow rate can be adjusted more flexibly according to the real-time water flow temperature. Different media have different gear adjustment ranges and methods, enabling the heat pump system where the water pump is located to adapt to more usage scenarios and effectively improving the user experience.

[0059] The technical solutions of the embodiments of the present application and the technical effects produced by the technical solutions of the present application will be described below through the description of several exemplary embodiments. It should be noted that the following embodiments can be referenced, borrowed, or combined with each other. For the same terms, similar features, and similar implementation steps in different embodiments, they will not be described repeatedly.

[0060] Figure 1 FIG. is a schematic diagram of the application scenario of the water pump adjustment method provided by the embodiment of the present application. Among them, the application environment may include a heat pump system, and the heat pump system includes a water pump 100, a pipeline, and a water pump flow rate adjustment component 200. Among them, the water pump 100 is connected to the pipeline, and the water pump 100 is electrically connected to the water pump flow rate adjustment component 200.

[0061] Specifically, the water pump flow rate adjustment component 200 monitors the water flow state of the pipeline in real time to determine whether it is necessary to adjust the minimum gear of the water pump 100. If it is necessary to adjust the minimum gear of the water pump 100, the minimum gear of the water pump 100 is adjusted to the target minimum gear according to the real-time water flow temperature, where the water flow state includes the real-time water flow temperature in the pipeline.

[0062] The above application scenario is only an example and does not limit the application scenario of the water pump adjustment method of the present application.

[0063] In some possible embodiments, taking the execution subject as the water pump flow rate adjustment component as an example, the embodiment of the present application provides a water pump adjustment method, which is applied to a heat pump system, as Figure 2 shown, and may include the following steps:

[0064] S210, monitor the water flow state of the pipeline in real time, and determine whether it is necessary to adjust the minimum gear of the water pump.

[0065] Among them, the heat pump system includes a pipeline and a water pump, and the pipeline is connected to the water pump; the water flow state may include the real-time water flow temperature in the pipeline; the water pump may include multiple gears, and different gears correspond to different water flow rates.

[0066] Specifically, the heat pump system may include a water flow switch, which can monitor the water flow state of the pipeline, determine whether it is necessary to adjust the water flow rate, and adjust the water pump gear to achieve the regulation of water flow. The water flow switch is used to monitor the on-off of the water flow in the water circuit. Real-time monitoring of the water flow state can timely detect the situation of too small or interrupted water flow, and can timely adjust the water pump gear to maintain the water flow state and reduce the frequent reporting of water flow faults, which affects the user experience.

[0067] In the specific implementation process, the water flow state of the pipeline is monitored in real time. If the water flow state is the first state, it is determined that the water pump needs to be adjusted in gear; if the water flow state is the second state, it is determined that the water pump does not need to be adjusted in gear, and the water flow state is continuously monitored; wherein, the first state is abnormal water flow, which may include no water flow fault or water flow less than the preset flow threshold, and the second state is normal water flow, which may include water flow greater than the preset threshold; when the water flow is abnormal, it can be considered that there is an increase in water resistance in the heat pump system, such as changes in the circulating medium, increase in the concentration of antifreeze, accumulation of scale, water quality differences in different regions, and installation of terminals. At this time, it is necessary to adjust the minimum gear to ensure that the heat pump system can still maintain water and maintain the stability of the water flow in the case of the minimum gear.

[0068] S220, if it is necessary to adjust the minimum gear of the water pump, then according to the real-time water flow temperature, adjust the minimum gear of the water pump to the target minimum gear.

[0069] Among them, the water flow state includes the real-time water flow temperature in the pipeline, and the minimum gear is the lowest gear at which the water pump can maintain water output.

[0070] Specifically, if it is determined according to the water flow state that it is necessary to adjust the minimum gear of the water pump, then determine the target minimum gear that needs to be adjusted according to the obtained real-time water flow temperature, and adjust the minimum gear of the water pump to the target minimum gear to ensure normal water output of the heat pump system.

[0071] In the specific implementation process, the fluid medium in the heat pump system is usually water or antifreeze. Since the temperature is dynamically changing, in some seasons and regions, the air temperature may drop suddenly, which may cause the water in the pipeline to freeze. A smaller amount of water is more likely to be frozen and blocked, and the water use demand cannot be guaranteed. Therefore, we can determine the target minimum gear based on the real-time water flow temperature. The obtained water flow state above may include the real-time water flow temperature in the pipeline. Determining the target minimum gear according to the real-time water flow temperature can efficiently determine the target minimum gear and improve the stability of the water flow in the heat pump system.

[0072] In some possible implementation manners, in the above steps, adjusting the minimum gear of the water pump to the target minimum gear according to the real-time water flow temperature includes:

[0073] Determine the target minimum gear based on the freezing point temperature and the real-time water flow temperature;

[0074] Adjust the minimum gear of the water pump to the target minimum gear.

[0075] Among them, the water flow state also includes the freezing point temperature of the fluid medium in the pipeline. The freezing point temperature refers to the temperature at which the fluid medium begins to freeze.

[0076] Specifically, when the gear of the water pump needs to be adjusted, the freezing point information of the fluid medium in the pipeline can be obtained, combined with the obtained real-time water flow temperature, to determine the corresponding target minimum gear, ensuring that there is continuous water flow for the fluid medium under the corresponding water flow temperature, and setting the minimum gear of the water pump to the target minimum gear to ensure the normal and stable water flow of the heat pump system.

[0077] In the specific implementation process, the freezing point temperature of the fluid medium in the heat pump system can be set on the line controller or the host according to the actual situation. The heat pump system may accumulate scale, change the antifreeze concentration or install terminals over time, resulting in the actual flow not reaching the set flow. The freezing point temperature of the fluid medium is less affected by other factors. Therefore, we can adaptively adjust the gear of the water pump based on the freezing point temperature so that the actual flow is as close as possible to the target demand flow.

[0078] In some possible implementation manners, the embodiment of the present application provides a water pump adjustment method, which is applied to a heat pump system. As Figure 3 shown, the step of determining the target minimum gear based on the freezing point temperature and the real-time water flow temperature may include:

[0079] S310, determine the real-time temperature range based on the preset water temperature range.

[0080] Among them, the water temperature range is preset and may include the corresponding relationship between the water temperature and the freezing point of the fluid medium.

[0081] S320, determine whether the real-time temperature range changes.

[0082] Specifically, the real-time water flow temperature is detected by a water temperature sensor. According to the preset water temperature range, the real-time temperature range where the real-time water flow temperature is located is determined. According to the temperature range and the real-time monitored water flow temperature, it is determined whether the real-time temperature range changes. According to the change situation of the range, different methods are adopted to determine the corresponding target minimum gear. Precise control of the water pump gear according to the water temperature zone can make the flow more conform to the actual demand and the effect is better.

[0083] In the specific implementation process, the freezing point temperature of the fluid medium corresponds to different water temperature ranges. The same freezing point temperature may also correspond to different water pump gears, resulting in different flow rates in the water circuit. The corresponding relationship between the freezing point temperature and the real-time temperature range can be shown in Table 1.

[0084] Table 1

[0085]

[0086] Among them, Q1 and Qn correspond to the flow rate of the water pump, n corresponds to the gear of the water pump, Twin represents the real-time water flow temperature, which can be detected by a water temperature sensor, and Tfrz represents the freezing point temperature of the fluid medium.

[0087] In the specific implementation process, after determining the freezing point temperature of the fluid medium, the range of the real-time water flow temperature can be determined according to the data in the row corresponding to the freezing point temperature in the table, so as to determine the corresponding minimum gear. For example, if the freezing point temperature Tfrz of the fluid medium in the current heat pump system is between Tf1 and Tf2, then determine the range where the real-time water flow temperature is located in the data of the first row in the table. If Twin is initially between Tw1 and Tw2, the water pump gear can be set to Q1. If it is subsequently detected that the real-time water flow temperature is between Tw2 and Tw3, it is determined that the real-time temperature range has changed, and the water pump gear is adjusted to the corresponding gear in the table.

[0088] S330, if the real-time temperature range has changed, then based on the real-time temperature range and the freezing point temperature, determine the target minimum gear.

[0089] Among them, the real-time temperature range is the temperature range where the real-time water flow temperature is located.

[0090] Specifically, if the real-time temperature range has changed, then determine the corresponding target minimum gear based on the freezing point temperature and the new real-time temperature range.

[0091] In the specific implementation process, the corresponding relationship between the freezing point temperature and the real-time temperature range can be shown in Table 1. If it is detected that the range has changed, then based on the water temperature range information corresponding to the freezing point temperature, use the gear corresponding to the real-time temperature range as the target minimum gear. For example, when the freezing point temperature is within the range of Tf1 and Tf2, and the real-time temperature range is the range corresponding to Tw1 and Tw2, the target minimum gear is Q1.

[0092] In some possible implementation manners, after the above steps, if it is necessary to adjust the minimum gear of the water pump, then according to the real-time water flow temperature, after adjusting the minimum gear of the water pump to the target minimum gear, the method further includes:

[0093] Update the historical adjustment times.

[0094] Among them, the historical adjustment times are the times of adjusting the minimum gear of the water pump.

[0095] Specifically, each time the water pump gear is adjusted, the adjustment times need to be recorded so that when the real-time water flow temperature does not cross intervals, the gear information to be adjusted can be determined according to the historical adjustment times, and the gear can also be adjusted when the temperature does not cross intervals, effectively ensuring the stability of the water flow.

[0096] In the specific implementation process, during the operation of the variable-frequency water pump, it is necessary to adjust the water pump gear. The adjustment times of the gear can be recorded to obtain the historical adjustment times. When the change in the real-time water flow temperature is small, the gear can be adjusted based on the historical adjustment times, and the temperature can be adjusted in a timely manner based on a smaller temperature change, making the water flow rate more stable and effectively improving the user experience.

[0097] In some possible implementation manners, in the above steps, based on the freezing point temperature and the real-time water flow temperature, determining the target minimum gear further includes:

[0098] If the real-time temperature interval does not change, determine the target minimum gear based on the historical adjustment times.

[0099] Specifically, if the real-time temperature interval does not change, it can be determined whether the real-time water flow temperature changes. If it changes, the target minimum gear can be determined according to the historical adjustment times and the water pump gear after the previous adjustment. When the temperature change is small, the water pump gear can also be adjusted, making the water pump adjustment more accurate and comprehensive, and improving the water pump performance.

[0100] In the specific implementation process, when it is necessary to adjust the water pump gear, the adjustment times of the gear can be recorded to obtain the historical adjustment times. When the change in the real-time water flow temperature is small, the water pump gear and the historical adjustment times can be added to obtain the target minimum gear. For example, when the real-time water flow temperature changes without crossing intervals, the current minimum water pump gear is 2nd gear, and the current historical adjustment times are obtained as 2 times, then the target minimum gear is determined to be 4th gear, and the corresponding target flow rate is Q4; among them, the initial value of the historical adjustment times is 0, and the historical adjustment times are cleared after a power failure reset or when the ambient temperature crosses intervals.

[0101] In some possible implementation manners, the above-mentioned real-time monitoring of the water flow state of the pipeline includes:

[0102] Real-time obtain the freezing point temperature of the fluid medium in the pipeline and the real-time water flow temperature in the pipeline;

[0103] Based on the freezing point temperature and the real-time water flow temperature, determine the initial minimum gear of the water pump.

[0104] Among them, the water flow state also includes the freezing point temperature of the fluid medium in the pipeline and the initial minimum gear of the water pump.

[0105] Specifically, the freezing point temperature of the fluid medium in the pipeline is obtained in real time, and the real-time water flow temperature is obtained through a sensor. Based on the freezing point temperature and the real-time water flow temperature, the corresponding minimum gear is determined in a preset associated information table, where the associated information table may include the associated information between the freezing point temperature, the real-time water flow temperature, and the corresponding water pump gear.

[0106] In the specific implementation process, generally, the fluid medium in the pipeline does not change, and the freezing point temperature does not change either. When determining the initial minimum gear, the corresponding initial minimum gear can be determined based on the real-time water flow temperature under a fixed freezing point temperature.

[0107] In some possible implementation manners, the above method further includes:

[0108] Monitoring the ambient temperature of the heat pump system through a temperature sensor;

[0109] Based on a preset ambient temperature range, determining whether there is a cross-range change in the ambient temperature;

[0110] If there is a cross-range change, the minimum gear of the water pump is adjusted to the initial minimum gear.

[0111] Among them, the range of the ambient temperature is preset.

[0112] Specifically, based on the ambient temperature sensor to monitor the ambient temperature of the heat pump system, and determine the corresponding range of the ambient temperature, and judge whether there is a cross-range change in the ambient temperature. If there is a cross-range change, the water pump gear is reset, and the minimum gear is adjusted to the initial minimum gear. The setting of the ambient temperature and the corresponding range can be as shown in Table 2.

[0113] Table 2

[0114]

[0115] Among them, Tambient represents the ambient temperature of the heat pump system, and Ta1 to Ta(n + 1) are constants.

[0116] Specifically, based on the ambient temperature sensor to monitor the ambient temperature of the heat pump system, and determine the corresponding range of the ambient temperature. For example, the initial ambient temperature is Tambient, and the initial temperature is between Ta1 and Ta2, that is, the initial ambient temperature range is Tambient-1. Subsequently, if it is detected that Tambient is between Ta2 and Ta3, and the ambient temperature range becomes Tambient-2, it can be judged that there is a cross-range change in the ambient temperature, then the water pump gear is reset, and the lowest gear of the water pump is adjusted to the corresponding initial minimum gear.

[0117] In some possible embodiments, the above method further includes:

[0118] If it is detected that a power failure occurs in the heat pump system, the minimum gear of the water pump is adjusted to the initial minimum gear.

[0119] Specifically, the variable-frequency water pump may be electric, so when a power failure occurs, the water pump may restart. After restarting, the gear of the water pump will be reset. If it is detected that a power failure occurs in the heat pump system or the unit where the heat pump system is located, the gear of the water pump is reset based on the freezing point temperature of the fluid medium in the water circuit and the corresponding water temperature, that is, the minimum gear of the water pump is adjusted to the initial minimum gear, ensuring that the water pump can start running from a known standard state every time, avoiding parameter setting chaos caused by accidental power failure or other reasons, and making the gear control more accurate.

[0120] In the above embodiment, by real-time monitoring the water flow state of the heat pump system pipeline, it is determined whether the minimum gear of the water pump needs to be adjusted according to the water flow state. If adjustment is required, the target minimum gear is determined according to the real-time water flow temperature in the water flow state and the water pump is adjusted to complete the adjustment of the minimum water flow of the water pump. Real-time monitoring of the water flow state can timely detect water flow faults in the water circuit, and real-time acquisition of the real-time water flow temperature can timely determine the target minimum gear and adjust it when a pipeline fault occurs, effectively improving the adjustment efficiency of the water pump flow, avoiding frequent reporting of water flow faults, and improving the stability of the water flow.

[0121] Further, when determining the target minimum gear based on the real-time water flow temperature, it is judged whether the water flow temperature crosses intervals. For the case where the temperature crosses intervals, based on the freezing point temperature of the fluid medium in the pipeline and the real-time water flow temperature, the target minimum gear corresponding to the interval is obtained. For the case where there is no interval crossing, the target minimum gear is determined according to the historical failure times. Accurately determining the corresponding minimum gear according to the water temperature partition can handle the water pump gear adjustment requirements in different temperature situations, adapt to water flow adjustments in different conditions, and make the water pump adjustment more flexible.

[0122] In addition, for different fluid media, the corresponding freezing point temperatures are obtained, which can make the water pump flow adjustment more flexible according to the real-time water flow temperature. Different media have different gear adjustment intervals and methods, enabling the heat pump system where the water pump is located to adapt to more usage scenarios and effectively improving the user experience.

[0123] In one example, the water pump adjustment method of the present application, as Figure 4 shown, may include:

[0124] Obtain the water flow state of the pipeline in real time, where the water flow state includes the real-time water flow temperature in the pipeline (i.e., Twin shown in the figure) and the freezing point temperature of the fluid medium in the pipeline (i.e., Tfrz shown in the figure);

[0125] Based on the freezing point temperature and the real-time water flow temperature, determine the initial minimum gear of the water pump (i.e., the initial Qmin(n) shown in the figure);

[0126] Determine whether it is necessary to adjust the minimum gear of the water pump according to the water flow state;

[0127] If it is not necessary to adjust the minimum gear, continue to obtain the water flow state;

[0128] If it is necessary to adjust the minimum gear of the water pump (i.e., report water flow failure shown in the figure), then based on the preset water temperature range, determine the real-time temperature range, where the real-time temperature range is the temperature range where the real-time water flow temperature is located;

[0129] Judge whether the real-time temperature range has changed (i.e., whether it crosses the range shown in the figure);

[0130] If the real-time temperature range has changed, then based on the real-time temperature range and the freezing point temperature, determine the target minimum gear (i.e., the Qmin(n) corresponding to the new range shown in the figure);

[0131] If the real-time temperature range has not changed, then based on the historical adjustment times (i.e., f shown in the figure), determine the target minimum gear (i.e., n=n + f shown in the figure), where the historical adjustment times is the number of times the minimum gear of the water pump is adjusted;

[0132] Adjust the minimum gear of the water pump to the target minimum gear (i.e., update the minimum gear to Qmin(n) shown in the figure);

[0133] Update the historical adjustment times (i.e., f=f + 1 shown in the figure).

[0134] The above water pump adjustment method can, by monitoring the water flow state of the heat pump system pipeline in real time, determine whether it is necessary to adjust the minimum gear of the water pump according to the water flow state. If adjustment is needed, it determines the target minimum gear according to the real-time water flow temperature in the water flow state and adjusts the water pump to complete the adjustment of the minimum water flow of the water pump. Real-time monitoring of the water flow state can timely detect water flow failures in the water circuit, and real-time acquisition of the real-time water flow temperature can timely determine the target minimum gear and adjust it when a pipeline failure occurs, effectively improving the adjustment efficiency of the water pump flow, avoiding frequent reporting of water flow failures, and improving the stability of the water flow.

[0135] Further, when determining the target minimum gear based on the real-time water flow temperature, it is judged whether the water flow temperature crosses intervals. For the case where the temperature crosses intervals, based on the freezing point temperature of the fluid medium in the pipeline and the real-time water flow temperature, the target minimum gear corresponding to the interval is obtained. For the case where there is no interval crossing, the target minimum gear is determined according to the historical failure times. By accurately determining the corresponding minimum gear according to the water temperature partition, the adjustment requirements of the water pump gear in different temperature situations can be handled, adapting to the water flow adjustment in different situations and making the water pump adjustment more flexible.

[0136] In addition, for different fluid media, the corresponding freezing point temperatures are obtained, which can make the water pump flow adjustment more flexible according to the real-time water flow temperature. Different media have different gear adjustment intervals and methods, enabling the heat pump system where the water pump is located to adapt to more usage scenarios and effectively improving the user experience.
