Description

Technical Field

[0001] The present application relates to the field of computers, and more specifically, to a method and device for determining resistance parameters, a storage medium, an electronic device, and a computer program product. Background Art

[0002] Hydraulic balancing technology is an important technology in heating and air-conditioning water systems. It directly affects the use effect of heating and air-conditioning and the energy saving of the system. Using special instruments to debug the hydraulic balancing valve can ensure that each end of the pipeline obtains the appropriate flow rate.

[0003] When designing a building, the resistance parameters are calculated and the hydraulic balancing valves are matched for each building, unit or floor room. However, there are many uncertainties in actual construction, and it is difficult to construct completely according to the drawings. In addition, the quality of the project and the quality of the product will affect the resistance. Unclean water will also clog valves, filters or heat exchange equipment. Users will also replace radiators by themselves. Therefore, the actual resistance of the terminal will deviate greatly from the design value. At present, the actual resistance parameters of the terminal are measured manually on the spot, which is inefficient.

[0004] In the project, if the heating (or cooling) at the terminal of a building, unit or floor machine room is not hot (or not cold), the engineering staff needs to conduct on-site inspection to find the location of the blockage. The on-site phenomenon is low flow, and the blockage may be in the building or in the external network system. Since there is no way to efficiently measure the actual resistance parameters of the terminal to help with the inspection, it is difficult to accurately find the location of the blockage.

[0030] In order to solve the above problem, a method for determining a resistance parameter is provided in this embodiment, including but not limited to being applied to the above mobile terminal. Figure 2 is a flow chart of a method for determining a resistance parameter according to an embodiment of the present application, such as Figure 2 As shown, the process includes the following steps S202 to S206 ， There is no specific order in which step S202 and step S204 are executed:

[0031] Step S202: adjusting the opening of the hydraulic balancing valve to a first opening; determining a resistance parameter corresponding to the hydraulic balancing valve according to the first opening to obtain a first resistance parameter, and determining a pressure difference between both ends of the hydraulic balancing valve when the hydraulic balancing valve is at the first opening to obtain a first pressure difference;

[0032] Optionally, before hydraulic balance adjustment, the hydraulic balance valve needs to be adjusted twice to collect different flow state data. During the first adjustment, the hydraulic balance valve is set to the first opening. Based on the first opening, the resistance parameter corresponding to the hydraulic balance valve at the first opening is obtained through the configuration file provided by the manufacturer of the hydraulic balance valve. At the same time, the pressure difference at both ends of the hydraulic balance valve is measured using an on-site differential pressure gauge, so that the resistance parameter K of the hydraulic balance valve at the first opening is collected.vf1 and pressure difference ΔP f1 , where K vf1 is the first resistance parameter, ΔP f1 is the first pressure difference.

[0033] Optionally, when adjusting the opening of the hydraulic balancing valve for the first time, the hydraulic balancing valve is opened to a certain opening f1, such as 2.5 turns, wherein f1 is a first opening.

[0034] Step S204: adjusting the opening of the hydraulic balancing valve to a second opening; determining a resistance parameter corresponding to the hydraulic balancing valve according to the second opening to obtain a second resistance parameter, and determining a pressure difference between both ends of the hydraulic balancing valve when the hydraulic balancing valve is at the second opening to obtain a second pressure difference;

[0035] Optionally, after the hydraulic balancing valve opening is adjusted, it is necessary to further adjust the hydraulic balancing valve to a second opening. Based on the second opening, the resistance parameter corresponding to the hydraulic balancing valve at the second opening is obtained through a configuration file provided by the manufacturer of the hydraulic balancing valve, and the pressure difference ΔP at this time is measured. f2 , to obtain the resistance K of the hydraulic balancing valve at the second opening vf2 and pressure difference ΔP f2 , where K vf2 is the second resistance parameter, ΔP f2 is the second pressure difference.

[0036] Optionally, when adjusting the opening of the hydraulic balancing valve for the second time, the hydraulic balancing valve is opened to a certain opening f2, such as 1 turn, wherein f2 is the second opening.

[0037] Step S206: Determine the resistance parameter of the end of the target pipeline according to the first resistance parameter, the second resistance parameter, the first pressure difference and the second pressure difference to obtain a target resistance parameter, wherein the hydraulic balancing valve is located in the target pipeline, and the end of the target pipeline is the last part through which the liquid in the target pipeline passes.

[0038] It should be noted that through calculation, not only can the precise resistance parameter of the target pipeline end, that is, the target resistance parameter, be obtained, but also it can be determined whether there is a blockage or short circuit at the end according to the size of the target resistance parameter, so as to quickly locate the problem and take corresponding maintenance measures.

[0039] It should be noted that the above steps, through two measurements combined with software calculations, can effectively and accurately determine the resistance parameters at the end of the unit level of the heating system, simplify the debugging process, improve work efficiency and the monitoring capability of system performance, and are of great significance for the maintenance and management of the heating system.

[0040] In the above steps, the first resistance parameter, the second resistance parameter, the first pressure difference and the second pressure difference are obtained by adjusting the hydraulic balancing valve twice, and calculation is performed based on the obtained first resistance parameter, the second resistance parameter, the first pressure difference and the second pressure difference, so as to obtain the resistance parameter of the end of the target pipeline, thereby improving the accuracy and efficiency of measuring the resistance parameter at the end of the pipeline, thereby solving the problem of low efficiency of relying on manual measurement of the resistance parameter at the end of the pipeline.

[0041] In an exemplary embodiment, determining the resistance parameter corresponding to the hydraulic balancing valve according to the first opening to obtain the first resistance parameter can be achieved by the following steps S11-S12:

[0042] Step S11: obtaining a target configuration file, wherein the target configuration file contains resistance parameters corresponding to different opening degrees of the hydraulic balancing valve;

[0043] Optionally, a target configuration file is usually provided by the manufacturer of the hydraulic balancing valve, which contains the resistance parameters (K v The resistance parameter reflects the flow control capability of the valve at different openings. Through the target configuration file, the system can quickly find the resistance parameter at the corresponding opening without complicated theoretical calculations.

[0044] Step S12: determining a resistance parameter corresponding to the hydraulic balancing valve from the target configuration file according to the first opening, to obtain the first resistance parameter;

[0045] Optionally, after determining the opening of the hydraulic balancing valve during the first test (the first opening f1), the resistance parameter corresponding to the opening is directly searched from the target configuration file, that is, the first resistance parameter K vf1 Through such direct table lookup operation, the specific resistance parameters of the valve at the current opening can be quickly and accurately obtained, paving the way for subsequent flow calculation and pressure difference measurement.

[0046] It should be noted that the use of the target configuration file greatly simplifies the process of determining the resistance parameters, avoids the complexity and uncertainty of theoretical calculations on site, and improves the debugging efficiency and accuracy. v The value directly reflects the performance of the valve. Using the configuration file can ensure that the parameters used in the adjustment process are the latest and most accurate, which helps to improve the accuracy of the entire adjustment process.

[0047] In an exemplary embodiment, determining the resistance parameter corresponding to the hydraulic balancing valve according to the second opening to obtain the second resistance parameter can be achieved by the following steps: determining the resistance parameter corresponding to the hydraulic balancing valve from the target configuration file according to the second opening to obtain the second resistance parameter.

[0048] Optionally, after determining the opening of the hydraulic balancing valve during the first test (the first opening f2), the resistance parameter corresponding to the opening is directly searched from the target configuration file, that is, the first resistance parameter K vf2 .

[0049] In an exemplary embodiment, determining the resistance parameter of the end of the target pipeline according to the first resistance parameter, the second resistance parameter, the first pressure difference, and the second pressure difference to obtain the target resistance parameter can be achieved by the following steps S21-S22:

[0050] Step S21: determining the flow rate of the liquid flowing through the hydraulic balancing valve at the first opening of the hydraulic balancing valve according to the first resistance parameter and the first pressure difference, to obtain a first flow rate; and determining the flow rate of the liquid flowing through the hydraulic balancing valve at the second opening of the hydraulic balancing valve according to the second resistance parameter and the second pressure difference, to obtain a second flow rate;

[0051] Alternatively, using the basic formula in fluid mechanics, ΔP = (Q / K v )2 is used to calculate the liquid flow through the hydraulic balancing valve at different openings.

[0052] Optionally, the first flow rate is obtained by the following formula:

[0053]

[0054] Among them, Q f1 is the first flow rate, K vf1 is the first resistance parameter, ΔP f1 is the first pressure difference.

[0055] Optionally, the second flow rate is obtained by the following formula:

[0056]

[0057] Among them, Q f2 is the second flow rate, K vf2 is the second resistance parameter, ΔP f2 is the second pressure difference.

[0058] Step S22: Calculate the target resistance parameter by the following formula 1:

[0059] (Q f1 / Kv f1 ) 2 +(Q m1 / Kv m1 ) 2 =(Q f2 / Kvf2 ) 2 +(Q m2 / Kv m2 ) 2 =△P 支 Formula 1;

[0060] Among them, (Q f1 / Kv f1 ) 2 is the first pressure difference, (Q m1 / Kv m1 ) 2 is the pressure difference between the two ends of the target pipeline when the hydraulic balancing valve is at the first opening, (Q f2 / Kv f2 ) 2 is the second pressure difference, (Q m2 / Kv m2 ) 2 is the pressure difference between the two ends of the target pipeline when the hydraulic balancing valve is at the second opening, ΔP 支 is the total pressure difference of the target pipeline; Q f1 is the first flow rate, Kv f1 is the first resistance parameter, Q m1 is the flow rate of the liquid flowing through the end of the target pipeline when the hydraulic balancing valve is at the first opening, Q m1 =Q f1 , Kv m1 is the resistance parameter at the end of the target pipeline when the hydraulic balancing valve is at the first opening, Kv m2 is the resistance parameter at the end of the target pipeline when the hydraulic balancing valve is at the second opening, Kv m1 =Kv m2 , the target resistance parameter is equal to the Kv m1 and Kv m2 , Q f2 is the second flow rate, Kv f2 is the second drag coefficient, Q f2 =Q m2 , Q m2 is the flow rate of the liquid flowing through the end of the target pipeline when the hydraulic balancing valve is at the second opening degree.

[0061] It should be noted that, since the hydraulic balancing valve and the target pipeline are a branch in the heating system, the total pressure difference of the branch remains unchanged, so the total pressure difference is equal to the first pressure difference plus the pressure difference at both ends of the end of the target pipeline when the hydraulic balancing valve is at the first opening, which is equal to the second pressure difference plus the pressure difference at both ends of the end of the target pipeline when the hydraulic balancing valve is at the second opening, that is, △P f1 +△Pm1 =△P f2 +△P m2 =△P 支 , where △P m1 is the pressure difference between the two ends of the target pipeline when the hydraulic balancing valve is at the first opening, △P m2 It is the pressure difference between the two ends of the end of the target pipeline when the hydraulic balancing valve is at the second opening degree.

[0062] It should be noted that since the hydraulic balancing valve and the end of the target pipeline are in series, when the hydraulic balancing valve opening remains unchanged, the flow rate of the liquid flowing through the hydraulic balancing valve and the flow rate of the liquid flowing through the end are equal, that is, Q f1 =Q m1 , Q f2 =Q m2 .

[0063] It should be noted that the resistance parameter at the end of the target pipeline is not affected by the opening of the hydraulic balancing valve and is fixed, so Kv m1 =Kv m2 .

[0064] It should be noted that the above formula 1 can be used to utilize the known Q f1 and Q f2 , and parameter K vf1 and K vf2 , the resistance parameter at the end of the target pipeline, that is, the target resistance parameter, is calculated by formula 1.

[0065] It should be noted that through the above steps, the terminal resistance parameters in the unit-level hydraulic balance of the heating system are accurately calculated. This calculation method not only simplifies complex technical operations, but also improves the efficiency of the diagnosis and adjustment process, which is of great significance for ensuring the stable operation of the heating system and saving energy and reducing consumption. Through quantitative data analysis and fault location, it is helpful to realize the intelligent management of the heating system, reduce operation and maintenance costs, and improve service quality.

[0066] In an exemplary embodiment, the method further comprises the following steps S31-S33:

[0067] Step S31: Calculate the ΔP using the formula 1 支 ;

[0068] Optionally, after obtaining the target resistance parameter, i.e. Kv m1 and Kv m2 Then, the total pressure difference △P can be calculated using formula 1 支 .

[0069] It should be noted that by applying Formula 1 again, the △P 支 The actual pressure difference data of the system at different openings is provided, which is of great reference value for the subsequent adjustment of the valve opening to achieve the target flow.

[0070] Step S32: When the flow rate of the liquid flowing through the hydraulic balancing valve and the end of the target pipeline is the target flow rate, the resistance parameter corresponding to the hydraulic balancing valve is calculated by the following formula 2: (Q / Kv f ) 2 +(Q / Kv m ) 2 =△P 支 ; Wherein, Q is the target flow, Kv f is the corresponding resistance parameter, Kv m is the target resistance parameter;

[0071] Optionally, once the target flow rate Q is determined, the opening of the hydraulic balancing valve at this time needs to be determined. The optimal resistance parameter K of the hydraulic balancing valve under the target flow rate Q can be calculated by Formula 2: vf , △P in Formula 2 支 has been calculated in step S31, and Kv m (K vm1 or K vm2 ) is the resistance parameter of the target pipeline end determined by step S22.

[0072] Step S33: determining the opening of the hydraulic balancing valve when the flow rate of the liquid flowing through the hydraulic balancing valve is the target flow rate according to the corresponding resistance parameter.

[0073] Optionally, the resistance parameter K at the target flow rate is determined vf After that, the valve manufacturer can provide K vf The relationship curve between value and opening degree is used to find out the corresponding target resistance parameter K vf This opening is the optimal opening that the hydraulic balancing valve needs to be adjusted to, to ensure that the liquid flow through the hydraulic balancing valve is exactly equal to the target flow Q.

[0074] It should be noted that when the liquid flow rate flowing through the target pipeline is the target flow rate, it can be ensured that the heating or cooling level of the system reaches the target level.

[0075] It should be noted that through the above steps, the efficiency and accuracy of the unit-level hydraulic balance adjustment method of the heating system have been brought to a new level. Through formula calculation and table lookup operation, not only can the actual resistance parameters at the end of the target pipeline be quickly determined, but the optimal opening of the balancing valve at the target flow rate can also be further calculated, thereby achieving precise adjustment of the system. This process avoids the trouble of multiple on-site commissioning, reduces energy waste, and improves the operational stability and economy of the heating system.

[0076] In an exemplary embodiment, the method further comprises the following steps S41-S43:

[0077] Step S41: Calculate the ΔP using the formula 1 支 ;

[0078] Optionally, after obtaining the target resistance parameter, i.e. Kv m1 and Kv m2 Then, the total pressure difference △P can be calculated using formula 1 支 .

[0079] Step S42: In the ΔP 支 When the flow rate of the target pipeline is greater than a first preset threshold and the flow rate of the liquid in the target pipeline is less than a preset flow rate, it is determined that there is a blockage inside the target pipeline;

[0080] It should be noted that according to the calculated △P 支 , if it exceeds a preset first threshold, and the liquid flow in the target pipeline is lower than a preset flow threshold at this time, then it can be determined that there is a blockage inside the target pipeline. This is because, if there is no blockage inside the pipeline, as the opening of the hydraulic balance valve increases, the flow should increase, and the pressure drop should also increase accordingly, but it will not exceed the normal range. When △P 支 When it increases abnormally and the flow rate through the pipe is lower than normal, it means that the flow inside the pipe is hindered, increasing the additional pressure drop and preventing the flow rate from increasing.

[0081] It should be noted that, by setting the first preset threshold and the preset flow rate, this step can help technicians quickly determine whether there is blockage inside the target pipeline, provide a basis for timely maintenance measures, and avoid increased energy consumption and decreased heating effect caused by pipeline blockage.

[0082] Step S43: In the ΔP 支 When the pressure is less than a second preset threshold, it is determined that there is a blockage in the pipeline other than the target pipeline or the pressure generated by the water pump is less than a preset standard threshold, wherein the second preset threshold is less than the first preset threshold.

[0083] It should be noted that when the total pressure difference △P 支 When it is lower than another preset second threshold, considering that there will be a certain pressure drop under normal operation of the target pipeline and the hydraulic balancing valve, if the pressure drop is too low, it may indicate that there are problems in other parts of the system, such as external pipeline blockage or insufficient water pump output. The second preset threshold is usually set smaller than the first threshold to distinguish between blockage inside and outside the target pipeline and whether the system pressure is normal.

[0084] It should be noted that the above steps use a quantitative method to determine the blockage in the heating system pipeline, which improves the efficiency and accuracy of the system's troubleshooting. This method avoids the shortcomings of traditional reliance on experience-based judgment. By calculating the pressure difference and setting the threshold, it can scientifically identify the blockage problems inside and outside the pipeline, as well as the performance status of the water pump, providing strong support for the maintenance and optimization of the heating system. By timely discovering and solving problems, the system downtime is reduced, the maintenance cost is reduced, and the heating effect and energy efficiency are guaranteed.

[0085] In an exemplary embodiment, after determining the resistance parameter of the end of the target pipeline according to the first resistance parameter, the second resistance parameter, the first pressure difference and the second pressure difference to obtain the target resistance parameter, the method further includes steps S51-S52 to implement:

[0086] Step S51: when the target resistance parameter is less than a third preset threshold, determining an internal short circuit at the end of the target pipeline;

[0087] It should be noted that when the calculated resistance parameter K at the end of the target pipeline is vm (K vm1 or K vm2 ) is less than the third preset threshold, which indicates that the hydraulic resistance of the terminal device is much lower than the normal level. In the heating system, this low resistance phenomenon is usually caused by a short circuit inside the pipeline, that is, the fluid does not pass through all or part of the terminal device (such as the radiator), but flows quickly through some undesigned path, resulting in the terminal device being unable to effectively dissipate heat or cool, thereby affecting the heating or air conditioning effect of the entire system.

[0088] It should be noted that by setting the third preset threshold, this step can effectively identify whether there is a short circuit problem inside the end of the target pipeline. This helps to take timely measures, such as closing or repairing the short circuit path, to ensure that the fluid can flow through the terminal device according to the designed path, thereby improving the system energy efficiency and uniformity of heating or air conditioning.

[0089] Step S52: when the target resistance parameter is greater than a fourth preset threshold, determining internal blockage of the end of the target pipeline, wherein the fourth preset threshold is greater than the third preset threshold.

[0090] It should be noted that, when the target resistance parameter is greater than the third preset threshold value and less than the fourth preset threshold value, it is determined that the terminal state of the target pipeline is normal.

[0091] It should be noted that if the calculated resistance parameter K at the end of the target pipeline is vm (K vm1 or K vm2 ) is greater than the fourth preset threshold, indicating that the hydraulic resistance of the terminal device is abnormally high, which is usually the result of internal blockage in the pipeline. Blockage may be caused by a variety of factors, such as valves not fully opened, impurity deposition in the pipeline, filter blockage, etc., which will lead to fluid flow obstruction and flow reduction, thus affecting system performance.

[0092] It should be noted that by setting the fourth preset threshold, this step can effectively determine whether there is a blockage inside the end of the target pipeline. Once the blockage is identified, the problem can be located more accurately, and the maintenance personnel can be guided to quickly clear the blockage point and restore the normal flow of the fluid, thereby avoiding the increase in system energy consumption and poor heating or air conditioning effects caused by the blockage.

[0093] It should be noted that steps S51 and S52 achieve accurate judgment of the short circuit and blockage inside the pipeline by comparing the resistance parameters at the end of the target pipeline with the preset threshold. This method not only simplifies the troubleshooting process and improves maintenance efficiency, but also helps to ensure the stable operation and optimization of the heating system or air-conditioning system. Through timely diagnosis and processing, it avoids system performance degradation and energy waste, and has a positive impact on improving the economy and user experience of the entire system. At the same time, the setting of the threshold can be adjusted according to the actual system characteristics and historical data to meet the fault diagnosis needs under different environments and conditions.

[0094] Obviously, the above-described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. In order to better understand the above method, the above process is described below in conjunction with the embodiments, but it is not intended to limit the technical solutions of the embodiments of the present invention. Figure 3 The overall flow chart of a method for determining a resistance parameter of an embodiment of the application is shown, specifically:

[0095] Step 1: During the first test, the balancing valve is opened to a certain opening f1, such as 2.5 turns, and the K corresponding to each opening is checked by the software (parameters provided by the manufacturer). v value), the current resistance value K can be obtained vf1, and then use the pressure differential meter to directly measure the current pressure difference △P at both ends of the balancing valve f1 , the software can calculate the current flow rate Q flowing through the balancing valve f1 (According to the formula ). Similarly, in the second test, the balancing valve is opened to another opening, such as 1 turn, and △P is obtained. f2 , the flow rate is Q f2 , resistance is K vf2 In this way, by changing the opening of the balancing valve twice, all six parameters of the balancing valve can be obtained through software table lookup, instrument measurement, and software calculation;

[0096] Step 2: At the same time, during the first test, the pressure difference between the two ends of the terminal (the building or unit in series with the balancing valve) is △P m1 , the flow rate is Q m1 , resistance is K vm1 ; The second time is △P m2 , the flow rate is Q m2 The resistance is Kvm2 ;

[0097] Step 3: Balance parameters, where the flow rates of the terminal and the balance valve are equal because they are connected in series on a pipeline, i.e. Q m1 =Q f1 , Q m2 =Q f2 ; The resistance at the end is fixed and has not changed, that is, K vm1 =K vm2 ;

[0098] Step 4: The balancing valve and terminal equipment are a branch in the heating system. The total pressure difference of this branch remains unchanged, and the equation △P is obtained. f1 +△P m1 =△P f2 +△P m2 =△P 支 ;

[0099] Step 5: Substitute the fluid mechanics formula △P=(Q / K v ) 2 , substituting into the above formula, we get:

[0100] (Q f1 / Kv f1 ) 2 +(Q m1 / Kv m1 ) 2 =(Q f2 / Kv f2 ) 2 +(Q m2 / Kv m2 ) 2 =△P支 ;

[0101] The Q obtained by the argument m1 =Q f1 , Q m2 =Q f2 , K vm1 =K vm2 Substituting into the above formula, we get: (Q f1 / K vf1 ) 2 +(Q f1 / K vm1 ) 2 =(Q f2 / K vf2) 2 +(Q f2 / K vm1 ) 2 =△P 支 , where Q f1 , Q f2 , K vf1 , K vf2 All have been measured, the only unknown is K vm (K vm1 ) and △P, we can calculate K vm At this point, by changing the opening of the balancing valve twice, all parameters are known;

[0102] Step 6: Substitute the target flow rate Q into the formula: (Q / K vf )2+(Q / K vm )2=△P 支 Since △P 支 , K vm , Q are known, we can get K under the target flow vf , and then use the manufacturer's curve of the balancing valve to get the opening that the balancing valve should give. At this opening, the flow through the balancing valve and the end is the target flow you want to achieve;

[0103] Step 7: In addition, an analysis can be made based on the total branch pressure head: if the pressure head is small, the system external network may be blocked or the water pump output is insufficient; if the pressure head is large but the branch flow is insufficient, there is a blockage inside the branch;

[0104] Step 8: According to the obtained terminal resistance parameter K vm , it can be analyzed whether the internal resistance at the end is blocked (K v value is larger) or short circuit (K v At the same time, the parameter can be stored as a terminal performance record as a supplementary description of the design resistance. When problems occur in the future, it can be compared to see if there is a problem with the terminal.

[0105] It should be noted that the present invention formalizes the dynamic debugging process of the heating system. Technical personnel do not need to master complex adjustment principles to achieve hydraulic balance adjustment of the heating system, which greatly simplifies the adjustment process and can fix the adjustment principles into the debugging software for use by multiple people.

[0106] It should be noted that the present application also has the following advantages: 1. The hydraulic balance adjustment method at the unit level of the heating system is converted into a measurement process implemented through a limited number of times, thereby reducing the workload of the staff, and the debugging process is quantified with higher accuracy; 2. By comparing the terminal resistance coefficient during the adjustment process, it is possible to determine whether blockage occurs inside the terminal, which helps maintenance personnel to detect problems in a timely manner, even when performing maintenance; 3. The hydraulic balance adjustment method is encapsulated into the system software, and the entire process can be controlled and predicted through scientific judgment of the debugging process, and debugging reports can be issued in batches for owners to inquire.
