Technical Field

[0001] This invention relates to the field of air conditioning technology, and in particular to an air conditioning pipeline testing method, device, air conditioner, and storage medium. Background Technology

[0002] In existing air conditioning systems, the healthy operation of the air conditioning piping is a key factor in ensuring the stable and efficient operation of the entire system. Good piping condition not only affects the energy efficiency and performance of the air conditioning system but also directly impacts its reliability and safety. The air conditioning piping is responsible for the flow of refrigerant; any cracks, leaks, or blockages can lead to decreased system efficiency or even complete failure. Therefore, timely and accurate monitoring and maintenance of the air conditioning piping is a crucial step in maintaining the efficient operation of the air conditioning system.

[0003] Currently, existing air conditioning duct inspections mainly rely on periodic physical checks or the use of sensors to detect certain specific nodes in the air conditioning ducts. This makes it difficult to reflect the real-time operating status of all locations in the air conditioning ducts, resulting in low accuracy. Furthermore, the lack of effective detection in the standby state of the air conditioner may lead to sudden failures when the air conditioning system is restarted, affecting the stability of the entire air conditioning system. In other words, the inability to accurately and effectively monitor the air conditioning ducts currently results in low stability and reliability of the air conditioning system. Summary of the Invention

[0004] This invention provides a method, apparatus, air conditioner, and storage medium for detecting air conditioning pipelines, aiming to solve the problem of low stability and reliability of air conditioning systems caused by the inability to accurately monitor air conditioning pipelines.

[0017] Please see Figure 1 , Figure 1 This is a flowchart illustrating the air conditioning pipe testing method provided in this embodiment of the invention. The air conditioning pipe testing method will be described in detail below. Figure 1 As shown, the method includes the following steps S110-S120.

[0018] S110. If the air conditioner is in standby mode, a pipeline model is constructed based on the obtained coordinate data of the air conditioner pipeline, and the air conditioner pipeline is detected based on the pipeline model to generate a standby detection result.

[0019] In this embodiment of the invention, when the air conditioner is in standby mode, the air conditioning system initiates an internal scanning program. The scanning device periodically scans the coordinate data of the internal piping of the air conditioner at intervals td, and constructs a piping model based on the coordinate data. This piping model is a geometric piping model. The scanning device can be a high-precision sensor, a laser scanner, or similar equipment. After constructing the piping model, the system detects whether the air conditioning piping is broken. Specifically, it detects whether the coordinate data in the piping model is continuous. If the coordinate data is continuous, the air conditioning piping is determined not to be broken; if the coordinate data is discontinuous, the air conditioning piping is determined to be broken. If the air conditioning piping is not broken, a standby detection result is generated based on the piping model, the original piping model, and a deformation threshold. Understandably, if the air conditioning piping is broken, an early warning mechanism is activated. Specifically, a clear warning message is displayed on the air conditioner's control panel, and the fault information is sent to the user's mobile device via the built-in network function, allowing the user to immediately understand the severity of the problem and take appropriate measures, such as turning off the air conditioner or contacting repair service, to prevent the problem from worsening. It should be noted that in this embodiment, the continuity of the coordinate data is used to determine whether the air conditioning duct has broken because the coordinate data of the air conditioning duct should show a continuous linear or curved path. Under normal circumstances, the coordinate data of the air conditioning duct will form a continuous, uninterrupted geometric shape. If the coordinates of the air conditioning duct suddenly break or a significant blank area appears in a certain area, it indicates that the air conditioning duct has broken at that location.

[0020] Further, generating a standby detection result based on the pipeline model, the original pipeline model, and the deformation threshold includes: calculating the coordinate data difference based on the coordinate data differences at various locations in the pipeline model and the original pipeline model; selecting the largest coordinate data difference as the pipeline directional deformation value; and generating the standby detection result based on the pipeline directional deformation value and the deformation threshold. Specifically, the deformation threshold includes a first deformation threshold and a second deformation threshold; generating the standby detection result based on the pipeline directional deformation value and the deformation threshold includes: if the pipeline directional deformation value is the first deformation threshold, then the standby detection result is set to the air conditioning pipeline being undeformed; if the pipeline directional deformation value is greater than the first deformation threshold and less than or equal to the second deformation threshold, then the standby detection result is set to the air conditioning pipeline having minor deformation; if the pipeline directional deformation value is greater than the second deformation threshold, then the standby detection result is set to the air conditioning pipeline having significant deformation. It should be noted that, in this embodiment, the original pipeline model refers to the pipeline geometric model established using scanning equipment after the air conditioning system is first installed or overhauled, which serves as a benchmark for comparison in the subsequent standby state; the deformation threshold refers to the maximum allowable deformation value of the standard air conditioning pipeline design.

[0021] For ease of understanding, let's assume the pipe path deformation value is... The deformation threshold is ,like =0 indicates that the air conditioning pipes are not deformed. The air conditioning system will mark the pipe status as intact and will automatically enter the pipe simulation test stage the next time the air conditioning is started. If 0 < ≤ This indicates minor deformation in the air conditioning piping, which triggers an update to the piping geometry model. The air conditioning system uploads the new piping geometry model to the database to update and correct the simulation geometry model after the air conditioner is turned on, ensuring the accuracy of the simulation results; if > This indicates that the air conditioning pipes have undergone significant deformation, and a comprehensive early warning mechanism should be activated immediately.

[0022] S120. If the air conditioner is in operation, the air conditioner pipeline is simulated and tested according to the standby detection result, the pipeline model, and the preset pipeline simulation model to generate an operating status level.

[0023] In this embodiment of the invention, after the air conditioner enters the operating state from the standby state, i.e., if the air conditioner is in the operating state, the air conditioning pipeline is simulated and tested according to the standby detection result, the pipeline model, and the preset pipeline simulation model to generate an operating status level. The pipeline simulation model is a multi-physics air conditioning pipeline simulation model integrating thermodynamics, fluid dynamics, solid mechanics, and acoustics. It should be noted that in this embodiment, during the construction of the pipeline simulation model, the mathematical equations of the coupled model are also set, the material parameters required by the model are defined, the initial boundary conditions of the model are set, the pipeline simulation model mesh is generated, and a suitable solver is selected for solving.

[0024] Further, step S120 includes: if the standby detection result indicates that the air conditioning pipe has slight deformation, then the preset pipe simulation model is corrected according to the pipe model to obtain a target pipe simulation model; if the standby detection result indicates that the air conditioning pipe is not deformed, then the preset pipe simulation model is used as the target pipe simulation model; the air conditioning pipe is simulated and detected according to the target pipe simulation model to generate the operating status level. Specifically, the simulation detection of the air conditioning pipe according to the target pipe simulation model to generate the operating status level specifically involves: collecting the operating parameters required by the target pipe simulation model, and setting the boundary conditions of the target pipe simulation model according to the operating parameters; calculating the refrigerant pressure, refrigerant temperature, pipe stress-strain value, and noise value generated by pipe vibration at various locations of the air conditioning pipe according to the boundary conditions and the target pipe simulation model; and evaluating the operating status level of the air conditioning pipe according to the refrigerant pressure, refrigerant temperature, pipe stress-strain value, noise value, and preset standard range at various locations of the air conditioning pipe. It should be noted that in this embodiment, the operating parameters required for the target pipeline simulation model will only be collected after the air conditioner has been running normally for a period of time (tm). It should also be noted that in this embodiment, the operating parameters include the refrigerant pressure and temperature at the compressor suction port and the refrigerant pressure and temperature at the compressor discharge port. Understandably, in other embodiments, the operating parameters may include other parameters, depending on actual needs.

[0025] Further, evaluating the operating condition level of the air-conditioning pipeline according to the refrigerant pressure, the refrigerant temperature, the pipeline stress and strain value, the noise value at each position of the air-conditioning pipeline and a preset standard range includes: selecting the worst one from the refrigerant pressure, the refrigerant temperature, the pipeline stress and strain value and the noise value at each position of the air-conditioning pipeline as the parameter to be evaluated; comparing the parameter to be evaluated with the preset standard range corresponding to the parameter to be evaluated to obtain the operating condition level of the air-conditioning pipeline. For ease of understanding, the parameter to be evaluated is denoted as Ri. Assuming Ri is the refrigerant temperature value, the preset standard range of the refrigerant temperature is as shown in Figure 2 shown, in Figure 2 , it includes Rmin, R1, R2 and Rmax, where Rmin refers to the lower limit value required by the standard; R1 refers to the threshold value close to the lower limit requirement of the standard; R2 refers to the threshold value close to the upper limit requirement of the standard; Rmax refers to the upper limit value required by the standard. Comparing Ri with the preset standard range of the refrigerant temperature; if Ri < Rmin or Ri > Rmax, then set the operating condition level of the air-conditioning pipeline to "poor"; if Rmin ≤ Ri ≤ R1 or R2 ≤ Ri ≤ Rmax, then set the operating condition level of the air-conditioning pipeline to "general"; if R1 < Ri < R2, then set the operating condition level of the air-conditioning pipeline to "good".

[0026] Figure 3 is a schematic flow chart of the air-conditioning pipeline detection method provided by another embodiment of the present invention. As shown in Figure 3 shown, in this embodiment, the method includes steps S110-S150. That is, in this embodiment, after step S120 of the above embodiment, the method further includes steps S130-S150.

[0027] S130. If the operating condition level is the first preset level, start the warning mechanism; S140. If the operating condition level is the second preset level, adjust the start time of the next simulation detection of the air-conditioning pipeline according to the first preset detection time adjustment strategy; S150. If the operating condition level is the third preset level, adjust the start time of the next simulation detection of the air-conditioning pipeline according to the second preset detection time adjustment strategy.

[0028] In this embodiment of the invention, if the operating status level is a first preset level, indicating that the operating status of the air conditioning pipeline is poor, then an early warning mechanism is activated, wherein the first preset level is "poor"; if the operating status level is a second preset level, indicating that the operating status of the air conditioning pipeline is average, then the start time of the next simulation test of the air conditioning pipeline is adjusted according to a first preset detection time adjustment strategy, wherein the second preset level is "average"; if the operating status level is a third preset level, indicating that the operating status of the air conditioning pipeline is good, then the start time of the next simulation test of the air conditioning pipeline is adjusted according to a second preset detection time adjustment strategy, wherein the third preset level is "good". Furthermore, the start time of the next simulation test of the air conditioning pipeline is adjusted according to the first preset detection time adjustment strategy. In a specific example, after time tn1, the second simulation test of the air conditioning pipeline is performed. If the operating status level of the second simulation test is "poor", the comprehensive early warning mechanism is immediately activated. If the operating status level of the second simulation test is "average", that is, two consecutive operating status levels are "average", then after time tn2, the third simulation test of the air conditioning pipeline is performed, and the detection is maintained at time tn2 in subsequent tests, where tm>tn1>tn2. If the operating status level of the second simulation test is "good", that is, the two operating status levels are "average" and "good" respectively, then the third simulation test of the air conditioning pipeline is performed in time tm. It should be noted that in this embodiment, when the operating status level is "normal" twice consecutively, it indicates that the air conditioning pipeline has a risk trend of exceeding the upper and lower limits of the standard, and the start time of the air conditioning pipeline simulation test needs to be accelerated; if the previous operating status level is "normal", the start time of the air conditioning pipeline simulation test is accelerated, and if the subsequent operating status level is "good", the start time of the pipeline simulation test is restored to the initial tm segment time and the test is repeated.

[0029] Furthermore, adjust the start time of the next simulation test of the air-conditioning pipeline according to the second preset detection time adjustment strategy. In a specific example, after a period of time tg1, the second simulation test of the air-conditioning pipeline is carried out. If the operating condition level of the second simulation pipeline test is "poor", the comprehensive warning mechanism is immediately started; if the operating condition level of the second simulation pipeline test is "normal", that is, the operating condition levels of the two tests are "good" and "normal" respectively, then it returns to the tm time period for the third simulation test of the air-conditioning pipeline; if the operating condition level of the second simulation pipeline test is "good", that is, there are two consecutive "good" operating condition levels, then after a period of time tg2, the third simulation test of the air-conditioning pipeline is carried out, and the subsequent tests are carried out for a period of time tg2. Among them, tm < tg1 < tg2. Explanation: The purpose to be achieved is that when the test results are both at the normal level for two consecutive times, it indicates that there is a risk trend of exceeding the upper and lower limits of the standard for the pipeline at this time, and the start time of the pipeline simulation test needs to be accelerated. It should be noted that in this embodiment, when the operating condition levels are both "good" for two consecutive times, it indicates that the air-conditioning pipeline has high safety at this time, and the start time of the pipeline simulation test should be reduced to save energy consumption; when the previous operating condition level is "good" and the start time of the pipeline simulation test is reduced, and the subsequent operating condition level is "normal", the start time of the pipeline simulation test is restored to the initial tm time period and the test is carried out again.

[0030] As Figure 4 shown, Figure 4 is the flow diagram of the air-conditioning pipeline monitoring in the standby state of the air-conditioning provided by the embodiment of the present invention. In Figure 4 during the standby operation state of the air-conditioning, regularly scan the coordinate data of the internal pipeline of the air-conditioning for a period of time td, construct a pipeline model (pipeline geometric model), and judge whether the air-conditioning pipeline is broken according to the pipeline model; if it is broken, start the comprehensive warning mechanism; if it is not broken, calculate the radial deformation value of the pipeline (the deformation value of the air-conditioning pipeline) according to the coordinate point differences at each position of the newly constructed pipeline model and the original pipeline model , and compare the radial deformation value of the pipeline with the deformation threshold ; if the air-conditioning pipeline is not deformed, =0, and it automatically enters the pipeline simulation test stage when the air-conditioning is started. If the air-conditioning pipeline has slight deformation, 0 < ≤ , upload the new pipeline geometric model to the database to update and correct the pipeline geometric model for the simulation test after the air-conditioning is started; if the air-conditioning pipeline has large deformation, > , start the comprehensive warning mechanism.

[0031] As Figure 5As shown Figure 5 is a simplified flowchart of air-conditioning pipeline monitoring during the operation of an air conditioner provided by an embodiment of the present invention. In Figure 5 , a thermo-fluid-solid-acoustic multi-physics field air-conditioning pipeline simulation model is constructed; after the air conditioner operates normally for a period of time tm, air-conditioning pipeline simulation detection is carried out; the operating parameters required by the air-conditioning pipeline simulation model are obtained, that is, key parameters such as the refrigerant pressure and temperature at the suction and exhaust ports of the compressor; the initial boundary conditions of the pipeline simulation model are set according to the obtained key parameters; according to the boundary conditions, the pipeline simulation model calculates the refrigerant pressure and temperature at each position of the pipeline, the pipeline stress and strain values, and the noise values generated by pipeline vibration; the calculation result Ri is compared with the preset interval of the pipeline design standard (i.e., the preset standard interval) to evaluate the operating condition level of the pipeline; if Ri < Rmin or Ri > Rmax, the operating condition level of the air-conditioning pipeline is set to "poor", and a comprehensive warning mechanism is activated; if Rmin ≤ Ri ≤ R1 or R2 ≤ Ri ≤ Rmax, the operating condition level of the air-conditioning pipeline is set to "general", and the next activation time of the air-conditioning pipeline simulation detection is adjusted accordingly according to the "general" level, that is, the next simulation detection start time of the air-conditioning pipeline is adjusted according to the first preset detection time adjustment strategy; if R1 < Ri < R2, the operating condition level of the air-conditioning pipeline is set to "good", and the next activation time of the air-conditioning pipeline simulation detection is adjusted accordingly according to the "good" level, that is, the next simulation detection start time of the air-conditioning pipeline is adjusted according to the second preset detection time adjustment strategy.

[0032] In summary, in this embodiment, during the standby state of the air conditioner, air-conditioning pipeline monitoring is carried out to judge the pipeline breakage situation, and the standby detection result is fed back to the pipeline simulation monitoring. During the operation state of the air conditioner, the operating condition level of the pipeline is evaluated according to the analysis result calculated by the constructed pipeline simulation model, and the next activation time of the pipeline simulation detection is dynamically adjusted according to the pipeline operating condition level, which significantly improves the reliability and safety of the system, reduces the consumption of energy and computing resources, and improves the energy efficiency and cost-effectiveness of the overall system.
