Description

Technical Field

[0001] This application relates to the field of home appliance technology, such as a piping system, a control method for preventing resonance in a piping system, and a storage medium. Background Technology

[0002] Currently, most refrigeration equipment uses a compressor in conjunction with a piping system for cooling. Since the compressor vibrates during operation, it causes the entire piping system to vibrate. This results in excessive noise and, over time, loose connections, affecting the overall stability of the piping system.

[0003] In order to reduce the vibration of the pipeline system, most related technologies use fixed components to increase the fixing force of the pipeline system. However, this still cannot avoid the vibration of the pipeline system. Moreover, most compressors at present are variable frequency compressors. As the operating frequency of the compressor changes, its vibration frequency changes, which can easily cause resonance with the pipeline system, thereby aggravating the vibration amplitude of the pipeline system, generating excessive noise, and reducing the overall service life of the pipeline system.

[0004] It is evident that how to avoid resonance between the compressor and the piping system, reduce the vibration amplitude of the piping system, and improve the overall stability of the piping system has become a technical problem that urgently needs to be solved by those skilled in the art.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0006] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0007] This disclosure provides a pipeline system, a control method for preventing resonance in the pipeline system, and a storage medium to address the technical problem that as the operating frequency of the compressor changes, its vibration frequency changes, easily causing resonance with the pipeline system and thus exacerbating the vibration amplitude of the pipeline system.

[0008] In some embodiments, the piping system includes: refrigerant pipes, a fixed rubber block, a rubber block adjustment mechanism, a vibration sensor, a compressor frequency determination module, and a controller assembly. Multiple refrigerant pipes are provided; the fixed rubber block is fixedly connected to multiple refrigerant pipes; the rubber block adjustment mechanism is disposed on the fixed rubber block for adjusting the hardness of the fixed rubber block; the vibration sensor is disposed on the refrigerant pipes and / or the fixed rubber block for detecting the vibration frequency of the piping system; the compressor frequency determination module is used to obtain the compressor operating frequency; the controller assembly is connected to the rubber block adjustment mechanism, the vibration sensor, and the compressor frequency determination module, and is used to control the rubber block adjustment mechanism to adjust the hardness of the fixed rubber block according to the vibration frequency of the piping system detected by the vibration sensor and the compressor operating frequency obtained by the compressor frequency determination module.

[0009] In some embodiments, the control method for preventing resonance in a piping system includes:

[0010] Determine the operating frequency of the compressor;

[0011] Obtain the vibration frequency of the pipeline system;

[0012] The hardness of the fixed rubber block is adjusted by controlling the rubber block adjustment mechanism based on the difference between the compressor's operating frequency and the vibration frequency of the pipeline system.

[0013] In some embodiments, the storage medium stores program instructions that, when executed, perform the control method for preventing resonance in the piping system according to any of the above embodiments.

[0014] The pipeline system, control method for preventing resonance in the pipeline system, and storage medium provided in this disclosure can achieve the following technical effects:

[0015] By securing the refrigerant pipes with adhesive blocks, the vibration amplitude of the refrigerant pipes can be reduced. The adhesive blocks are equipped with an adjustment mechanism to adjust their hardness. By changing the hardness of the adhesive blocks, the securing force on the refrigerant pipes is adjusted, thereby changing the vibration frequency of the piping system. During the adjustment process, vibration sensors and a compressor frequency determination module determine the vibration frequencies of the piping system and compressor in real time. The hardness of the adhesive blocks is then adjusted based on these vibration frequencies, ensuring that the vibration frequency of the piping system avoids the compressor's frequency. This prevents resonance between the piping system and the compressor, effectively reducing the vibration amplitude of the piping system, decreasing noise, eliminating stress risks, and improving the overall stability of the piping system.

Wearable devices may include, for example, smartwatches, smart bracelets, pedometers, etc.

[0037] Combination Figure 1-4 As shown, this embodiment of the present disclosure provides a piping system including: refrigerant pipes 100, fixed adhesive blocks 300, adhesive block adjusting mechanism 400, vibration sensor 500, compressor frequency determination module 600, and controller assembly 700. Multiple refrigerant pipes 100 are provided; fixed adhesive blocks 300 are fixedly connected to multiple refrigerant pipes 100; the adhesive block adjusting mechanism 400 is disposed on the fixed adhesive blocks 300 and used to adjust the hardness of the fixed adhesive blocks 300; the vibration sensor 500 is disposed on the refrigerant pipes 100 and / or the fixed adhesive blocks 300 and used to detect the vibration frequency of the piping system; the compressor frequency determination module 600 is used to obtain the compressor operating frequency; the controller assembly 700 is connected to the adhesive block adjusting mechanism 400, the vibration sensor 500, and the compressor frequency determination module 600, and is used to control the adhesive block adjusting mechanism 400 to adjust the hardness of the fixed adhesive blocks 300 according to the vibration frequency of the piping system detected by the vibration sensor 500 and the compressor operating frequency obtained by the compressor frequency determination module 600.

[0038] The piping system provided in this embodiment uses a fixing block 300 to fix the refrigerant pipe 100, which reduces the vibration amplitude of the refrigerant pipe 100. The fixing block 300 is equipped with a fixing block adjustment mechanism 400, which allows for adjustment of the hardness of the fixing block 300. By changing the hardness of the fixing block, the fixing force on the refrigerant pipe 100 is adjusted, thereby changing the vibration frequency of the piping system. During the adjustment process, the vibration frequencies of the piping system and the compressor are determined in real time by a vibration sensor 500 and a compressor frequency determination module 600. The hardness of the fixing block 300 is then adjusted according to the vibration frequencies of the piping system and the compressor, ensuring that the vibration frequency of the piping system avoids the frequency of the compressor. This prevents resonance between the piping system and the compressor, effectively reducing the vibration amplitude of the piping system, decreasing noise, eliminating stress risks in the piping system, and improving the overall stability of the piping system.

[0039] Optionally, the fixing block 300 is provided with multiple pipe fixing holes 301 for fixing the refrigerant pipe 100. This allows the refrigerant pipe 100 to pass through the pipe fixing holes 301 on the fixing block 300, thus better securing the refrigerant pipe 100. Furthermore, the use of a sleeve connection method to fix the refrigerant pipe 100 makes the connection between the fixing block 300 and the refrigerant pipe 100 more flexible and easier to adjust.

[0040] Optionally, the fixing block 300 has a polygonal structure, and the pipe fixing hole 301 is located at the corner of the polygonal structure. In this way, the refrigerant pipe 100 is fixed at the corner of the fixing block 300, which can fix the refrigerant pipe 100 from the position between multiple refrigerant pipes 100, reducing the space occupied by the fixing block 300, and separating multiple refrigerant pipes 100 by a certain distance to prevent the refrigerant pipes 100 from affecting each other.

[0041] The shape of the fixing block 300 is related to the number of refrigerant pipes 100 it fixes. For example, when the fixing block 300 is used to fix three refrigerant pipes 100, it has a triangular structure and fixes the refrigerant pipes 100 by using the positions of the three vertices.

[0042] Optionally, the pipe fixing hole 301 is located on the edge of the fixing block 300 and has an opening 302 facing the edge of the fixing block 300. This facilitates the insertion of the refrigerant pipe 100 into the pipe fixing hole 301 through the opening 302 on the edge of the fixing block 300, improving the ease of connection between the refrigerant pipe 100 and the fixing block 300, and facilitating the disassembly and installation of the fixing block 300.

[0043] Optionally, the pipe fixing hole 301 is circular, and its diameter is less than or equal to the diameter of the refrigerant pipe 100. This allows the pipe fixing hole 301 to be filled while the refrigerant pipe 100 is fixed inside, making full use of the elasticity of the fixing block 300 and improving the fixing effect on the refrigerant pipe 100.

[0044] Optionally, the vibration sensor 500 has multiple sensing elements, which are respectively disposed on multiple refrigerant pipes 100 and fixing blocks 300. In this way, vibrations on the refrigerant pipes 100 and fixing blocks 300 can be detected by multiple sensing elements, and the accuracy of detection can be improved by combining the vibration frequencies of each part.

[0045] Optionally, the adhesive block adjustment mechanism 400 includes: a fixed plate 401, a movable plate 402, a telescopic rod 403, and a drive assembly 404. The fixed plate 401 is attached to one side of the fixed adhesive block 300; the movable plate 402 is attached to the other side of the fixed adhesive block 300; the telescopic rod 403 is connected to the movable plate 402; and the drive assembly 404 is connected to the telescopic rod 403 for driving the telescopic rod 403 to move the movable plate 402 to adjust the distance between the movable plate 402 and the fixed plate 401. In this way, the drive assembly 404 can be used to drive the telescopic rod 403 to adjust the distance between the fixed plate 401 and the movable plate 402. The elasticity of the fixed rubber block 300 itself can be used to tighten the fixed rubber block 300 when the fixed plate 401 and the movable plate 402 are pressing on the fixed rubber block 300, thereby increasing the hardness of the fixed rubber block 300 and thus increasing the fixing force on the refrigerant pipe 100 and reducing the vibration frequency of the piping system. Conversely, increasing the gap between the fixed plate 401 and the movable plate 402 can loosen the fixed rubber block 300, reduce its hardness, and give it a certain degree of elasticity, thereby reducing the suppression of the vibration frequency of the refrigerant pipe 100 and increasing its vibration frequency.

[0046] Among them, the drive component 404 can be a motor, and the telescopic rod 403 can be a threaded rod.

[0047] Combination Figure 5 As shown, this disclosure provides a control method for preventing resonance in a pipeline system, including:

[0048] S01, determine the operating frequency of the compressor;

[0049] S02, obtain the vibration frequency of the pipeline system;

[0050] S03, based on the difference between the compressor's operating frequency and the pipeline system's vibration frequency, controls the rubber block adjustment mechanism to adjust the hardness of the fixed rubber block.

[0051] The control method for preventing resonance in a pipeline system provided in this embodiment can determine the vibration frequency of the pipeline system and the compressor in real time. Then, the hardness of the fixing block can be adjusted according to the frequency of the pipeline system and the compressor, so that the vibration frequency of the pipeline system avoids the frequency of the compressor, thereby avoiding resonance between the pipeline system and the compressor. This can effectively reduce the vibration amplitude of the pipeline system, reduce noise, eliminate stress risks in the pipeline system, and improve the overall stability of the pipeline system.

[0052] Optionally, in step S01, obtaining the compressor's operating frequency includes: connecting the compressor frequency determination module to the processor of the refrigeration equipment, extracting its system operating data, and determining the compressor's current operating frequency. This allows for a more accurate and convenient acquisition of the compressor's operating frequency. Generally, the compressor's vibration frequency is directly related to its operating frequency. Based on this, the compressor's vibration frequency can be efficiently determined, facilitating the control of the pipeline system's vibration frequency to avoid the compressor's vibration frequency, thereby preventing resonance in the pipeline system.

[0053] Understandably, the compressor's operating frequency can also be obtained directly by installing sensors on the compressor.

[0054] Optionally, S02, obtaining the vibration frequency of the pipeline system includes: when multiple vibration sensors are installed on the pipeline system, acquiring vibration frequency data detected by the multiple sensors, calculating the average value of the multiple vibration frequency data, and determining the average value as the vibration frequency of the pipeline system. In this way, by detecting vibration frequency data at multiple locations on the pipeline system and calculating its average value, the overall vibration frequency of the pipeline system can be more accurately reflected, reducing measurement errors.

[0055] like Figure 6 As shown, optionally, in step S03, controlling the rubber block adjusting mechanism to adjust the hardness of the fixed rubber block according to the difference between the compressor's operating frequency and the vibration frequency of the pipeline system includes:

[0056] S31, calculate the difference between the compressor's operating frequency and the vibration frequency of the piping system;

[0057] S32, if the difference between the operating frequency of the compressor and the vibration frequency of the pipeline system is greater than or equal to the first threshold, control the rubber block adjustment mechanism to maintain the current hardness of the rubber block.

[0058] S33, if the difference between the compressor's operating frequency and the pipeline system's vibration frequency is less than a first threshold, control the rubber block adjustment mechanism to increase or decrease the hardness of the fixed rubber block.

[0059] Thus, resonance between the compressor and the piping system refers to the same vibration frequency between the two. Therefore, considering the detection error of the vibration sensor, when the difference between the two is greater than or equal to the first threshold, it indicates that there is a significant difference in the vibration frequency between the two, and resonance will not occur. At this time, maintaining the current hardness of the fixing block can prevent resonance between the compressor and the piping system. When the difference between the two is less than the first preset value, it indicates that the vibration frequency between the two is relatively close, and the possibility of resonance between the compressor and the piping system is high. At this time, by increasing or decreasing the hardness of the fixing block, the vibration frequency of the piping system can be changed, so that the vibration frequency between the two can be separated to a certain extent. This can effectively prevent resonance between the compressor and the piping system, avoid excessive vibration amplitude, effectively reduce noise, eliminate stress risks in the piping system, and improve the overall stability of the piping system.

[0060] Optionally, the value of the first threshold is determined based on the operating frequency of the compressor. Since the compressor's vibration is the source of vibration and its vibration frequency cannot be adjusted, determining the first threshold based on the compressor's operating frequency and controlling the vibration frequency of the piping system accordingly can effectively prevent the piping system's vibration frequency from approaching the compressor's vibration frequency, reducing the risk of resonance and improving the overall stability of the piping system.

[0061] Optionally, the first threshold is 1% to 3% of the compressor's operating frequency. Preferably, the first threshold is 2% of the compressor's operating frequency. In this way, resonance is generally possible when the vibration frequencies of two objects are within 3% of each other. Therefore, by setting the first threshold within 1% to 3%, when the difference between the compressor's operating frequency and the vibration frequency of the piping system is less than 1% to 3% of the compressor's operating frequency, the control block adjustment mechanism adjusts the hardness of the fixed block, thereby changing the vibration frequency of the piping system. This better avoids resonance between the compressor and the piping system, eliminates stress risks in the piping system, and improves the stability of the piping system.

[0062] For example, if the first threshold is 2% of the compressor's operating frequency, and the compressor's operating frequency is 50 Hz, then the value of the first threshold is 1 Hz.

[0063] like Figure 7 As shown, optionally, in step S33, if the difference between the compressor's operating frequency and the pipeline system's vibration frequency is less than a first threshold, the control mechanism of the rubber block adjusting mechanism increases or decreases the hardness of the fixed rubber block includes:

[0064] S34, obtain the current hardness of the fixed rubber block;

[0065] S35, if the current hardness of the fixed rubber block is determined to be within the first preset range, control the rubber block adjustment mechanism to increase the hardness of the fixed rubber block;

[0066] S36, if it is determined that the current hardness of the fixed rubber block is within the second preset range, control the rubber block adjustment mechanism to reduce the hardness of the fixed rubber block.

[0067] In this way, when it is necessary to adjust the hardness of the fixing block, the current hardness of the fixing block can be obtained. Based on the range of the current hardness of the fixing block, the adjusting mechanism can be controlled to increase or decrease the hardness of the fixing block. If the current hardness of the fixing block is high, the hardness of the fixing block is decreased; if the current hardness of the fixing block is low, the hardness of the fixing block is increased. This allows for reasonable adjustment of the hardness of the fixing block within its adjustable range, thereby changing the vibration frequency of the pipeline system, preventing resonance between the pipeline system and the compressor, and preventing damage to the fixing block or adjustment failure caused by exceeding its adjustable range when adjusting the hardness.

[0068] Optionally, obtaining the current hardness of the fixing block includes:

[0069] Determine the distance between the fixed and movable plates of the rubber block adjustment mechanism;

[0070] The hardness of the fixing block is determined based on the relationship between the distance between the fixing plate and the moving plate and the hardness of the fixing block.

[0071] In this way, the distance between the fixed piece and the movable piece can more intuitively and easily reflect the hardness of the fixed rubber block, improving the ease and accuracy of determining the hardness of the fixed rubber block.

[0072] Understandably, there is a clear one-to-one correspondence between the distance between the fixed and movable plates and the hardness of the fixed rubber block. This correspondence can be obtained through adjustment experiments and pre-stored in the controller assembly for use when determining the current hardness of the fixed rubber block. Thus, determining the hardness of the fixed rubber block through a preset correspondence improves the convenience of hardness determination.

[0073] Understandably, the distance between the fixed plate and the movable plate can be determined based on the operating data of the telescopic rod that controls the movement of the movable plate. The initial state of the telescopic rod results in the largest distance between the fixed and movable plates, at which point there is no compression effect on the fixed rubber block. For every 1 mm the telescopic rod moves the movable plate towards the fixed plate, the distance between the fixed and movable plates decreases by 1 mm. The distance between the fixed and movable plates is calculated by determining the extension length of the telescopic rod based on its operating data.

[0074] Optionally, an adjustable range for the hardness of the fixing block is determined. A first preset range is the first half of the adjustable hardness range, and a second preset range is the second half. The range of the first preset range is larger than that of the second preset range. Since the first preset range is the first half of the adjustable hardness range, if the current hardness is within the first preset range, it indicates that the fixing block has room for increased hardness. Therefore, the hardness of the fixing block can be increased. Conversely, if it is within the second preset range, the hardness of the fixing block can be decreased. The fact that the first preset range is larger than the second preset range increases the probability of increasing the hardness of the fixing block during the adjustment phase. Prioritizing the increase of the hardness of the fixing block improves the fixing effect on the refrigerant pipe.

[0075] Optionally, the adjustable hardness range of the fixing rubber block is determined, with the first preset range being the first four-fifths of the adjustable hardness range of the fixing rubber block and the second preset range being the last one-fifth of the adjustable hardness range of the fixing rubber block. In this way, by determining the adjustable range of the hardness of the fixing block, the adjustment strategy for the fixing block can be controlled. When the current hardness of the fixing block is within the first four-fifths of the adjustable range, it indicates that the hardness of the fixing block still has room for adjustment. Therefore, the hardness of the fixing block should be increased first. This can change the vibration frequency of the fixing block, widening the gap between it and the vibration frequency of the compressor to avoid resonance. At the same time, increasing the hardness of the fixing block can further improve the fixing force of the refrigerant pipe, reduce the vibration amplitude of the refrigerant pipe, and better reduce vibration and noise. When the current hardness of the fixing block is within the last one-fifth of its adjustable range, it indicates that the hardness of the fixing block is about to reach its upper limit. At this point, further increasing the hardness may easily damage the fixing block, or the adjustment needs may still not be met even after reaching the upper limit of the hardness of the fixing block. Therefore, the hardness of the fixing block should be decreased first, so that its adjustable range is larger, which can better ensure that the vibration frequency of the piping system is separated from the vibration frequency of the compressor to avoid resonance.

[0076] Understandably, the vibration frequency of the piping system mentioned above refers to the average value of the vibration frequencies at multiple locations of the refrigerant pipe and the fixed rubber block.

[0077] Understandably, the hardness of the fixed rubber block can be represented by the distance between the fixed plate and the movable plate. When the fixed plate and the movable plate are not parallel, the hardness of the fixed rubber block can be represented by the position between the center points of the fixed plate and the movable plate.

[0078] Combination Figure 8 As shown, this disclosure provides another control method for preventing resonance in a pipeline system, including:

[0079] S04, control the rubber block adjustment mechanism to adjust the hardness of the fixed rubber block to the maximum value of its adjustable hardness range;

[0080] S05, if the difference between the compressor's operating frequency and the pipeline system's vibration frequency is less than a first threshold, control the rubber block adjustment mechanism to reduce the hardness of the fixed rubber block.

[0081] By setting the initial hardness of the fixing block to its maximum value, a high fixing force can be provided to the refrigerant pipes during the compressor's start-up phase, effectively suppressing refrigerant pipe vibration. When there is no risk of resonance between the piping system and the compressor, the fixing block exerts its optimal fixing force, improving the overall stability of the piping system. When the difference between the compressor's operating frequency and the piping system's vibration frequency is less than a first threshold, indicating a risk of resonance between the compressor and the piping system, the hardness of the fixing block is reduced to change the refrigerant pipe's vibration frequency, thereby widening the gap between it and the compressor's vibration frequency and preventing resonance between the two.

The control device includes a processor 100 and a memory 101. Optionally, the device may further include a communication interface 102 and a bus 103.
