Similarly, a processor (or multiple processors or memories) can be used to implement one or more modules or units. In addition, each module or unit can be a part of the overall module or unit that includes the function of the module or unit.

[0062] In the specific implementation of the present application, any data related to an object, such as data involved in the process of an 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, if any data related to the object as described above is involved in the embodiments of the present application, 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.

[0063] To make the objectives, technical solutions, and advantages of this application more clear, the following will further describe the embodiments of this application in detail with reference to the accompanying drawings.

[0064] First, the technical terms related to this application are introduced and explained:

[0065] Heat pump system: It may include a water pump, a heat pump, or a heat exchanger. The water flow temperature passing through the water pump system can change based on the water temperature setting.

[0066] In the prior art, the variable-frequency water pump control generally performs constant-flow regulation, using a fixed flow rate to control the temperature difference between the inlet and outlet water. This regulation method outputs a fixed flow rate and cannot accurately match the actual demand. If the flow rate is too large, it is difficult to reach the set temperature; if the flow rate is too small, it is easy for the heat pump to quickly reach the set temperature, resulting in frequent start and stop of the heat pump system. Under different working conditions, different water temperatures, and different set temperatures, the target water temperature required by the unit of the outlet water control system changes in real time. The constant-flow regulation method cannot dynamically respond to the changing water temperature demand.

[0067] The flow rate regulation method, device, component, heat pump system, computer-readable storage medium, and computer program product provided by this application aim to solve at least one of the above technical problems in the prior art.

[0068] Regarding at least one of the above technical problems or areas for improvement in the related art, this application proposes a flow rate regulation method, device, component, heat pump system, computer-readable storage medium, and computer program product. The flow rate regulation method provided by this solution determines the corresponding real-time temperature difference by monitoring the inlet water temperature and outlet water temperature of the heat pump system in real time, and determines the target gear based on the obtained real-time temperature difference. The outlet water flow rate of the target water pump is regulated based on the target gear. By monitoring the inlet and outlet water temperatures in real time, the real-time temperature difference can be obtained in a timely manner, and the temperature difference can be regulated in multiple intervals to achieve a stable transition from a small temperature difference to a large temperature difference, avoiding frequent start and stop situations, realizing dynamic regulation of the flow rate, and enhancing the flow rate regulation performance of the water pump.

[0069] Furthermore, the shutdown temperature corresponding to the heat pump system can be determined based on the ambient temperature. The target temperature difference of the heat pump system is determined according to the shutdown temperature, the predetermined set temperature, and the inlet water temperature of the heat pump system. The real-time temperature difference is compared with the target temperature difference to determine whether to increase or decrease the water pump gear, which can more accurately determine the target gear to achieve a stable transition of the temperature difference, avoid sudden rises and falls in the outlet water temperature of the heat pump system, ensure the comfort of water use, and improve the user experience.

[0070] In addition, before adjusting the water pump gear and obtaining the target gear, the running time of the heat pump system can be judged to determine whether the operation is stable, so as to avoid the influence of the temperature fluctuation of the heat pump system within a period of time after startup on the judgment of the temperature difference, resulting in ineffective adjustment of the water pump gear. When the operation is not stable, only the operation of increasing the water pump gear can be performed, and the operation of increasing the gear has little influence on the water flow temperature, which can make the heat pump system more stable.

[0071] 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 referred to, learned from, or combined with each other. For the same terms, similar features, and similar implementation steps in different embodiments, they will not be described repeatedly.

[0072] Figure 1 It is a schematic diagram of the application scenario of the flow rate adjustment method provided by the embodiments of the present application. Among them, the application environment may include a heat pump system 100, and the heat pump system 100 includes a water pump 200 and a water pump flow rate adjustment component 300, and the water pump 200 is electrically connected to the water pump flow rate adjustment component 300.

[0073] Specifically, the water pump flow rate adjustment component 300 controls the temperature sensor to monitor the inlet water temperature and outlet water temperature of the heat pump system 100 in real time, determines the corresponding real-time temperature difference, determines the target gear based on the real-time temperature difference, adjusts the outlet water flow rate of the target water pump 200 based on the target gear, and realizes the flow rate adjustment of the water pump 200 based on the temperature difference between the inlet and outlet water of the heat pump system.

[0074] The above application scenario is only an example and does not limit the application scenario of the flow rate adjustment method of the present application.

[0075] In some possible embodiments, taking the execution subject as the water pump flow rate adjustment component as an example, the embodiments of the present application provide a flow rate adjustment method, which is applied to a heat pump system, as Figure 2 shown, and may include the following steps:

[0076] S210, monitor the inlet water temperature and outlet water temperature of the heat pump system in real time, and determine the corresponding real-time temperature difference.

[0077] Among them, the heat pump system includes a target water pump.

[0078] Specifically, the temperature sensor is used to monitor the inlet water temperature and outlet water temperature of the heat pump system in real time, determine the corresponding real-time temperature difference, and then modify the gear of the target water pump based on the temperature difference to obtain the corresponding flow rate, so as to adjust the inlet water temperature and outlet water temperature of the heat pump system, so that the heat pump system can operate stably and improve the user experience.

[0079] In the specific implementation process, a heat pump system refers to a system that can change the water flow temperature. It can include a heat pump and a water pump. In this case, the above-mentioned inlet water temperature and outlet water temperature are the inlet water temperature and outlet water temperature of the heat pump. It can also include a heat exchanger and a water pump. In this case, the above-mentioned inlet water temperature and outlet water temperature are the inlet water temperature and outlet water temperature on the water side of the heat exchanger. Among them, the water pump can be installed at the outlet of the heat pump or heat exchanger, or at the inlet of the heat pump or heat exchanger. Specifically, the heat pump or heat exchanger can be selected according to actual needs. Based on the inlet and outlet water temperatures of the heat pump or heat exchanger, the gear of the target water pump is adjusted to enable the outlet water temperature of the heat pump system to meet the temperature requirements set by the user.

[0080] In the specific implementation process, the outlet water temperature can be greater than or less than the inlet water temperature. When calculating the real-time temperature difference, the difference between the inlet water temperature and the outlet water temperature can be obtained, and the absolute value of the difference is used as the corresponding real-time temperature difference, which can adapt to different water flow temperature change situations and improve the applicability of the above method.

[0081] S220. Based on the real-time temperature difference, determine the target gear.

[0082] Specifically, based on the temperatures of the input and output water flows of the heat pump system, the real-time temperature difference is determined. By comparing the temperature difference with the required temperature difference, the target gear corresponding to the target water pump is determined, and the gear of the target water pump is adjusted to maintain the stability and efficiency of the heat pump system.

[0083] In the specific implementation process, the corresponding relationship between the temperature difference and the target gear can be set in advance. After obtaining the real-time temperature difference, the corresponding target gear can be determined based on the corresponding relationship. Or a functional relationship related to the gear can be set, and the corresponding target gear is determined based on the real-time temperature difference and the functional relationship. The method of obtaining the target gear based on the real-time temperature difference is not limited to the above two methods, and other methods that can achieve this step can also be used. There is no limit here, and it can be specifically selected according to the actual situation.

[0084] S230. Based on the target gear, adjust the outlet water flow of the target water pump.

[0085] Specifically, after determining the target gear corresponding to the target water pump, the target water pump is set to the target gear for water output to control the water output flow, which can effectively improve the performance of the corresponding heat pump system.

[0086] In the specific implementation process, the steps of adjusting the target water pump based on the target gear may include: adjusting the operating parameters of the target water pump based on the target gear. After setting, the actual operating condition of the water pump can be checked to ensure that the target gear has been reached. Among them, after setting the target gear, the running time after gear switching can be judged, and a time threshold can be set. Exceeding the corresponding time threshold indicates that the water pump has reached the set gear. After that, the target water pump can be adjusted according to the real-time temperature difference.

[0087] In some possible implementation manners, in the above steps, determining the target gear based on the real-time temperature difference includes:

[0088] Determining the target temperature of the heat pump system;

[0089] Based on the inlet water temperature and the target temperature, determining the target temperature difference;

[0090] Based on the real-time temperature difference and the target temperature difference, determining the target gear.

[0091] Specifically, determining the target temperature that the heat pump system needs to reach, obtaining the real-time temperature difference based on the inlet water temperature and the outlet water temperature, determining the target temperature difference based on the inlet water temperature and the target temperature of the heat pump system, and comparing the real-time temperature difference with the target temperature difference is essentially comparing the outlet water temperature with the target temperature, and determining the target gear of the target water pump so that the outlet water temperature gradually approaches the target temperature.

[0092] In the specific implementation process, the target temperature can be the set temperature or the shutdown temperature. The temperature requirement set by the user is the set temperature. Due to the influence of the external environmental temperature, in some environmental temperatures, when the heat pump system meets the shutdown temperature, it can also reach the temperature set by the user. Set the corresponding target temperature according to the actual situation so that the heat pump system can flexibly meet different temperature requirements.

[0093] In some possible implementation manners, in the above steps, determining the target temperature of the heat pump system includes:

[0094] Obtaining the current environmental temperature of the heat pump system;

[0095] According to the current environmental temperature of the heat pump system, determining the target temperature of the heat pump system.

[0096] Specifically, the current environmental temperature of the heat pump system is monitored in real time through an environmental temperature sensor, and based on the current environmental temperature, the target temperature required by the heat pump system is determined. When the environmental temperature fluctuates greatly, the heat pump system may need to be adjusted more frequently or precisely. Obtaining the environmental temperature in real time can make the operation of the heat pump system more stable.

[0097] In the specific implementation process, when determining the shutdown temperature of the heat pump system according to the current ambient temperature, the difference between the ambient temperature and the required target temperature is usually considered. Generally, the shutdown temperature can be set 15 to 20 degrees higher than the required target temperature to ensure that the heat pump can still operate efficiently at lower ambient temperatures. At the same time, heat loss and changes in the coefficient of performance of the heat pump need to be considered to ensure energy conservation and comfort.

[0098] In some possible implementation manners, in the above step, determining the target temperature of the heat pump system according to the current ambient temperature of the heat pump system includes:

[0099] Determining the target shutdown temperature of the heat pump system according to the current ambient temperature of the heat pump system;

[0100] Obtaining a preset set temperature;

[0101] Determining the target temperature of the heat pump system according to the target shutdown temperature and the set temperature.

[0102] Specifically, according to the current ambient temperature of the heat pump system, determine the target shutdown temperature of the heat pump system, obtain the preset set temperature, and determine the target temperature that the heat pump system needs to reach according to the target shutdown temperature and the set temperature.

[0103] In the specific implementation process, by determining the magnitude relationship between the set temperature and the target shutdown temperature, the smaller one of them can be used as the target temperature to meet the user's water use requirements based on the smaller target temperature, which can reduce the energy consumption of the heat pump system. Or, based on a preset selection rule, the target temperature can be selected from the set temperature and the target shutdown temperature to improve the performance of the heat pump system.

[0104] In the specific implementation process, as Figure 3 shown, Tw_in is the inlet water temperature, △t is the target temperature difference, and A, B, and C can represent the deadband coefficients, which are used to prevent the calculated value of the target temperature difference from exceeding the reasonable range. The range of the A value can be set from 0 to 2, the range of the B value can be set from 5 to 10, and the range of the C value can be set from 0 to 10. For different inlet water temperatures, the corresponding deadband coefficients are also different. The calculation formula for the target temperature difference can be:

[0105] △t = Max[Min(Ts, Tstop + An) - Tw_in, Bn]

[0106] Among them, Ts is the set temperature, Tstop is the target shutdown temperature, Min(Ts, Tstop + An), this part calculates the minimum value among the set temperature, the target shutdown temperature and An, which means that if the set temperature is lower than Tstop + An, the target temperature is the set temperature, and if the set temperature is higher than Tstop + An, the target temperature is Tstop + An; the calculation of the Max part means that if the difference between the target temperature and the inlet water temperature is higher than Bn, the difference between the target temperature and the inlet water temperature is taken as the target temperature difference, and if the difference between the target temperature and the inlet water temperature is lower than Bn, the target temperature difference is Bn.

[0107] In some possible implementation manners, in the above steps, determining the target shutdown temperature of the heat pump system according to the current ambient temperature of the heat pump system includes:

[0108] Determining the original shutdown temperature of the heat pump system according to the current ambient temperature of the heat pump system;

[0109] Performing parameter correction on the original shutdown temperature to obtain the target shutdown temperature.

[0110] Among them, the original shutdown temperature may be the shutdown temperature preset when the heat pump system is started.

[0111] Specifically, determining the original shutdown temperature of the heat pump system according to the current ambient temperature of the heat pump system, and detecting the ambient temperature in real time to perform parameter correction on the original shutdown temperature according to the ambient temperature to obtain the corresponding target shutdown temperature.

[0112] In the specific implementation process, taking the heat pump system including a heat pump as an example, when the ambient temperature is low, the shutdown temperature can be increased. This is because the efficiency of the heat pump decreases in a low-temperature environment. To ensure that the heat pump can continue to operate and provide sufficient heat, the system may adjust the shutdown temperature to prevent the heat pump from frequently shutting down when it cannot reach the expected indoor temperature. The shutdown temperature can also be decreased to protect the heat pump system and prevent damage caused by long-term operation at extremely low temperatures. Decreasing the shutdown temperature can reduce the working pressure of the heat pump under extreme conditions and prevent excessive wear and energy consumption; when the ambient temperature is high, the shutdown temperature can be decreased to prevent overheating, reduce the working burden of the heat pump, and also reduce the startup times of the heat pump, thereby saving energy and extending the service life of the equipment.

[0113] In some possible implementation manners, in the above steps, determining the target temperature of the heat pump system according to the target shutdown temperature and the set temperature includes:

[0114] Comparing the target shutdown temperature and the set temperature to determine the lowest temperature;

[0115] Taking the lowest temperature as the target temperature of the heat pump system.

[0116] Among them, the lowest temperature refers to the lowest temperature between the target shutdown temperature and the set temperature.

[0117] Specifically, compare the target shutdown temperature and the set temperature to determine the lower temperature between the two, and use this temperature as the target temperature of the heat pump system, which can reduce the energy consumption of the heat pump system under the condition of meeting the outlet water temperature.

[0118] In the specific implementation process, if the target temperature is set too high, the heat pump system may operate at an unnecessary high temperature, resulting in energy waste; setting a lower target temperature can prevent the system from overheating, reduce equipment wear, extend equipment life, help maintain the water flow temperature at a constant comfortable level, avoid frequent start-stop of the heat pump caused by too high temperature, increase equipment wear and failure risk, and in a cold environment, too high temperature may also cause the heat pump to operate outside the defrosting cycle for too long, increasing the possibility of frosting; therefore, selecting the lowest of the set temperature and the shutdown temperature as the target temperature helps the heat pump system to achieve efficient energy utilization and long-term stable operation of the equipment while ensuring user needs.

[0119] In some possible implementation manners, in the above steps, determining the target gear based on the real-time temperature difference and the target temperature difference includes:

[0120] Obtain the current gear of the target water pump;

[0121] If the target temperature difference is less than the real-time temperature difference, increase the gear on the basis of the current gear to obtain the target gear;

[0122] If the target temperature difference is greater than the real-time temperature difference, decrease the gear on the basis of the current gear to obtain the target gear.

[0123] Specifically, obtain the current gear of the target water pump. If the target temperature difference is less than the real-time temperature difference, increase the gear on the basis of the current gear to obtain the target gear. If the target temperature difference is greater than the real-time temperature difference, decrease the gear on the basis of the current gear to obtain the target gear.

[0124] In the specific implementation process, the size of increasing or decreasing the gear can be set based on the preset number of gears. For example, set to adjust one gear each time. If the target temperature difference is less than the real-time temperature difference, increase one gear on the basis of the current gear to obtain the target gear. If the target temperature difference is greater than the real-time temperature difference, decrease one gear on the basis of the current gear to obtain the target gear. Modify and increase or decrease one gear each time, making the operation of the target water pump relatively stable, without sudden drops or rises, increasing the life of the target water pump. The specifically adjusted gear can be flexibly set according to requirements.

[0125] In the specific implementation process, when comparing the target temperature difference with the real-time temperature difference, a buffer value can be set. When determining whether the target temperature difference is less than the real-time temperature difference, the target temperature difference can be updated based on the buffer value to determine whether the target temperature difference is less than or equal to the real-time temperature difference. For example, if the buffer value is set to 1, then 1 is added to the target temperature difference to determine whether the increased temperature difference is less than or equal to the real-time temperature difference. When determining whether the target temperature difference is greater than the real-time temperature difference, the target temperature difference can also be updated based on the buffer value to determine whether the updated temperature difference is greater than the real-time temperature difference. This can avoid incorrect adjustment of the gear caused by extremely small temperature fluctuations. For example, when the target temperature difference fluctuates by 0.1 degree less than the real-time temperature difference, there is no need to adjust the gear, which can make the operation of the target water pump more stable.

[0126] In some possible implementation manners, in the above step of determining the target gear based on the real-time temperature difference and the target temperature difference, it further includes:

[0127] Obtain the running time of the heat pump system;

[0128] If the running time reaches the preset stable time, increase or decrease the gear based on the magnitudes of the target temperature difference and the real-time temperature difference on the basis of the current gear;

[0129] If the running time does not reach the preset stable time, increase the gear based on the magnitudes of the target temperature difference and the real-time temperature difference on the basis of the current gear.

[0130] Wherein, the running time refers to the running time of the heat pump system from startup to the current time.

[0131] Specifically, obtain the running time of the heat pump system. If the running time reaches the preset stable time, it means that the operation of the heat pump system has been relatively stable, then increase or decrease the gear based on the magnitudes of the target temperature difference and the real-time temperature difference on the basis of the current gear. If the running time does not reach the preset stable time, only the gear can be increased on the basis of the current gear because when the heat pump system is not stable, the temperature fluctuates greatly, and increasing the gear has a smaller impact on the water flow temperature. After the heat pump system is stable, the temperature is relatively stable, and then the gear can be increased or decreased.

[0132] In the specific implementation process, the range of the preset stable time can include 20 to 30 minutes, and the specific range can be set according to actual requirements.

[0133] In the specific implementation process, such as Figure 4As shown, when the heat pump system is started, it can operate based on the initial flow rate. Here, the initial flow rate can be the flow rate corresponding to the initial gear of the target water pump, or the flow rate corresponding to the initial gear obtained based on historical gear data, or the flow rate corresponding to the initial gear set by the user. Determine the operating time of the heat pump system, and judge whether the operating time (i.e., Time shown in the figure) exceeds the preset stable time (i.e., Time_limit shown in the figure). If the operating time does not exceed the preset stable time, the water pump gear can only be increased. If the operating time exceeds the preset stable time, the water pump gear can be increased or decreased (i.e., free adjustment shown in the figure).

[0134] In some possible implementation manners, in the above step of determining the target gear based on the real-time temperature difference, it further includes:

[0135] Determine whether gear adjustment has been performed during the current operation of the heat pump system;

[0136] If gear adjustment has been performed, determine the operating time after gear adjustment;

[0137] If the operating time meets the preset time threshold, determine the target gear based on the real-time temperature difference.

[0138] Here, the current operation of the heat pump system includes the operation process of the heat pump system after it is started and before it is stopped in the current instance.

[0139] Specifically, determine whether gear adjustment has been performed during the operation process of the heat pump system in the current instance. If gear adjustment has been performed, determine the operating time after the closest previous gear adjustment. If the operating time meets the preset time threshold, determine the target gear based on the real-time temperature difference.

[0140] In the specific implementation process, the range of the preset time threshold can include 60 seconds to 120 seconds, and the specific value can be set based on requirements.

[0141] In the specific implementation process, such as Figure 5As shown, after adjusting the gear of the target water pump, determine the running time after adjusting the target flow rate corresponding to the previous target gear (i.e., Qn shown in the figure). Determine whether the running time meets the preset time threshold (i.e., T shown in the figure). If the running time meets the preset time threshold, determine the target gear based on the real-time temperature difference. If the target temperature difference is less than the real-time temperature difference, increase the gear on the basis of the current gear (i.e., n shown in the figure) to obtain the target gear (i.e., n + 1 shown in the figure) to obtain the water outlet flow rate (i.e., Q(n + 1) shown in the figure). If the target temperature difference is greater than the real-time temperature difference, decrease the gear on the basis of the current gear to obtain the target gear (i.e., n - 1 shown in the figure) to obtain the water outlet flow rate (i.e., Q(n - 1) shown in the figure). By regulating the target water temperature difference in multiple intervals, a stable transition from a small temperature difference to a large temperature difference can be achieved. The small temperature difference ensures comfort, and the large temperature difference ensures a high water outlet temperature.

[0142] In the above embodiment, by monitoring the inlet water temperature and outlet water temperature of the heat pump system in real time, the corresponding real-time temperature difference is determined, and based on the obtained real-time temperature difference, the target gear is determined. The outlet water flow rate of the target water pump is adjusted based on the target gear. By monitoring the inlet and outlet water temperatures in real time, the real-time temperature difference can be obtained in a timely manner. The temperature difference is regulated in multiple intervals to achieve a stable transition from a small temperature difference to a large temperature difference, avoiding frequent start-up and stop situations, realizing dynamic adjustment of the flow rate, and enhancing the flow rate adjustment performance of the water pump.

[0143] Furthermore, the shutdown temperature corresponding to the heat pump system can be determined based on the ambient temperature. According to the shutdown temperature, the predetermined set temperature, and the inlet water temperature of the heat pump system, the target temperature difference of the heat pump system is determined. The real-time temperature difference is compared with the target temperature difference to determine whether to increase or decrease the water pump gear, which can more accurately determine the target gear to achieve a stable transition of the temperature difference, avoid sudden rises and falls in the outlet water temperature of the heat pump system, ensure the comfort of water use, and improve the user experience.

[0144] In addition, before adjusting the water pump gear and obtaining the target gear, the running time of the heat pump system can be judged to determine whether the operation is stable, avoiding the influence of the temperature fluctuation of the heat pump system within a period of time after startup on the judgment of the temperature difference, resulting in ineffective adjustment of the water pump gear. When the operation is not stable, only the operation of increasing the water pump gear can be performed. The operation of increasing the gear has little influence on the water flow temperature and can make the heat pump system more stable.

[0145] In one example, the flow rate adjustment method of the present application, as Figure 6 shown, may include:

[0146] Monitor the inlet water temperature and outlet water temperature of the heat pump system in real time, and determine the corresponding real-time temperature difference;

[0147] Determine the target temperature of the heat pump system, and based on the inlet water temperature and the target temperature, determine the target temperature difference;

[0148] Obtain the operating time of the heat pump system;

[0149] If the operating time has not reached the preset stable time, increase the gear based on the magnitudes of the target temperature difference and the real-time temperature difference on the basis of the current gear;

[0150] If the operating time has reached the preset stable time, obtain the current gear of the target water pump;

[0151] If the target temperature difference is less than the real-time temperature difference, increase the gear on the basis of the current gear to obtain the target gear;

[0152] If the target temperature difference is greater than the real-time temperature difference, decrease the gear on the basis of the current gear to obtain the target gear;

[0153] Adjust the water outlet flow rate of the target water pump based on the target gear.

[0154] The above flow rate adjustment method, by monitoring the inlet water temperature and the outlet water temperature of the heat pump system in real time, determines the corresponding real-time temperature difference, and based on the obtained real-time temperature difference, determines the target gear, and adjusts the water outlet flow rate of the target water pump based on the target gear. By monitoring the inlet and outlet water temperatures in real time, the real-time temperature difference can be obtained in a timely manner, the temperature difference can be regulated in multiple intervals, a stable transition from a small temperature difference to a large temperature difference can be achieved, the situation of frequent start-up and stop can be avoided, the dynamic adjustment of the flow rate is realized, and the flow rate adjustment performance of the water pump is enhanced.

[0155] Furthermore, the shutdown temperature corresponding to the heat pump system can be determined based on the ambient temperature. According to the shutdown temperature, the predetermined set temperature, and the inlet water temperature of the heat pump system, the target temperature difference of the heat pump system is determined, and the real-time temperature difference is compared with the target temperature difference, so as to determine the increase or decrease of the water pump gear, which can more accurately determine the target gear to achieve a stable transition of the temperature difference, avoid the sudden rise and fall of the outlet water temperature of the heat pump system, ensure the comfort of water use, and improve the user experience.

[0156] In addition, before adjusting the water pump gear and obtaining the target gear, the operating time of the heat pump system can be judged to determine whether the operation is stable, so as to avoid the influence of the temperature fluctuation of the heat pump system within a period of time after startup on the judgment of the temperature difference, resulting in ineffective adjustment of the water pump gear. When the operation is not stable, only the operation of increasing the water pump gear can be performed, and the operation of increasing the gear has little influence on the water flow temperature, which can make the heat pump system more stable.
