Description

Technical Field

[0001] The present application relates to the field of household appliance technology, for example, to a pipeline system, a control method for preventing resonance of the pipeline system, and a storage medium. Background Art

[0002] At present, most refrigeration equipment uses a compressor in conjunction with a piping system for refrigeration. Since the compressor will generate vibration during operation, it will drive the entire piping system to vibrate. On the one hand, it causes excessive noise. On the other hand, long-term vibration can easily cause the interface to loosen, affecting the stability of the overall piping system.

[0003] In order to reduce the vibration of the pipeline system in the related technology, most of them use fixing components to increase the fixing force of the pipeline system, but this still cannot avoid the vibration of the pipeline system, and most of the compressors at this stage are variable frequency compressors. As the operating frequency of the compressor changes, its vibration frequency changes, which is easy to resonate 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 can be seen that how to avoid resonance between the compressor and the piping system, reduce the vibration amplitude of the piping system, improve the overall stability of the piping system, and reduce the noise of the piping system have become technical problems that need to be urgently solved by technical personnel in this field.

[0005] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field. Summary of the invention

[0006] In order to provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. The summary is not an extensive review, nor is it intended to identify key / critical components or delineate the scope of protection of these embodiments, but rather serves as a prelude to the detailed description that follows.

[0007] The embodiments of the present disclosure provide a pipeline system, a control method for preventing resonance of the pipeline system, and a storage medium to solve the technical problem that as the operating frequency of the compressor changes, its vibration frequency changes, which easily resonates with the pipeline system, thereby aggravating the vibration amplitude of the pipeline system.

[0008] In some embodiments, the pipeline system includes: a refrigerant pipe, a fixed rubber block, an air pressure regulating mechanism, a vibration sensor, a compressor frequency determination module and a controller component. There are multiple refrigerant pipes; the fixed rubber block is fixedly connected to the multiple refrigerant pipes, and an air bag is arranged inside the fixed rubber block; the air pressure regulating mechanism is connected to the air bag to control the air pressure in the air bag; the vibration sensor is arranged on the refrigerant pipe and / or the fixed rubber block to detect the vibration frequency of the pipeline system; the compressor frequency determination module is used to obtain the compressor operating frequency; the controller component is connected to the air pressure regulating mechanism, the vibration sensor and the compressor frequency determination module, and is used to control the air pressure regulating mechanism to adjust the air pressure of the air bag of the fixed rubber block according to the vibration frequency of the pipeline system detected by the vibration sensor and the compressor operating frequency obtained by the compressor frequency determination module.

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

[0010] Determine the operating frequency of the compressor;

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

[0012] According to the difference between the operating frequency of the compressor and the vibration frequency of the pipeline system, the air pressure regulating mechanism is controlled to adjust the air pressure in the airbag.

[0013] In some embodiments, the storage medium stores program instructions, and when the program instructions are run, they execute the control method for preventing resonance of the pipeline system according to any of the above embodiments.

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

[0015] By fixing the refrigerant pipe with a fixed rubber block, the vibration amplitude of the refrigerant pipe can be reduced, and an air bag is arranged in the fixed rubber block. By filling gas into the air bag, the tightness of the overall fixed rubber block can be adjusted. The fixed rubber blocks with different tightness have different fixing forces on the refrigerant pipe, which can change the vibration frequency of the pipeline system. During the adjustment process, the vibration frequency of the refrigerant pipe and the compressor is determined in real time by the vibration sensor and the compressor frequency determination module, and then the air pressure of the air bag inside the fixed rubber block is adjusted according to the frequency of the refrigerant pipe and the compressor. The tightness of the fixed rubber block is changed by adjusting the air pressure of the air bag, and then the vibration frequency of the fixed rubber block and the refrigerant pipe fixed by the fixed rubber block is changed, so that the vibration frequency of the pipeline system avoids the frequency of the compressor and avoids resonance between the refrigerant pipe and the compressor. The vibration amplitude of the refrigerant pipe can be effectively reduced, noise can be reduced, the stress risk of the pipeline system can be reduced, and the overall stability of the pipeline system can be improved. The air bag inside the fixed rubber block can absorb vibration waves, further consume vibration energy, reduce vibration amplitude, and reduce noise.

[0037] Combination Figure 1-4 As shown, an embodiment of the present disclosure provides a piping system including: a refrigerant pipe 200 , a fixing rubber block 300 , an air pressure regulating mechanism 400 , a vibration sensor 500 , a compressor frequency determination module 600 and a controller assembly 700 . There are multiple refrigerant pipes 200; the fixed rubber block 300 is fixedly connected to the multiple refrigerant pipes 200, and an air bag 301 is arranged inside the fixed rubber block 300; the air pressure regulating mechanism 400 is connected to the air bag 301, and is used to control the air pressure in the air bag 301; the vibration sensor 500 is arranged on the refrigerant pipe 200 and / or the fixed rubber block 300, and is used to detect the vibration frequency of the pipeline system; the compressor frequency determination module 600 is used to obtain the compressor operating frequency; the controller component 700 is connected to the air pressure regulating mechanism 400, the vibration sensor 500 and the compressor frequency determination module 600, and is used to control the air pressure regulating mechanism 400 to adjust the air pressure of the air bag 301 of the fixed rubber block 300 according to the vibration frequency of the pipeline system detected by the vibration sensor 500 and the compressor operating frequency obtained by the compressor frequency determination module 600.

[0038] By adopting the pipeline system provided by the embodiment of the present disclosure, the refrigerant pipe 200 is fixed by the fixed rubber block 300, so that the vibration amplitude of the refrigerant pipe 200 can be reduced, and an air bag 301 is arranged in the fixed rubber block 300. By filling gas into the air bag 301, the tightness of the overall fixed rubber block 300 can be adjusted. The fixed rubber blocks 300 with different tightness have different fixing forces on the refrigerant pipe 200, so that the vibration frequency of the pipeline system can be changed. During the adjustment process, the vibration frequencies of the refrigerant pipe 200 and the compressor are determined in real time by the vibration sensor 500 and the compressor frequency determination module 600, and then the vibration frequencies of the refrigerant pipe 200 and the compressor are determined according to the frequencies of the refrigerant pipe 200 and the compressor. The air pressure of the airbag 301 inside the fixed rubber block 300 is adjusted at a high rate. The tightness of the fixed rubber block 300 is changed by adjusting the air pressure of the airbag 301, thereby changing the vibration frequency of the fixed rubber block 300 and the refrigerant pipe 200 fixed by the fixed rubber block 300, so that the vibration frequency of the pipeline system avoids the frequency of the compressor, and avoids resonance between the refrigerant pipe 200 and the compressor. The vibration amplitude of the refrigerant pipe 200 can be effectively reduced, the noise can be reduced, the stress risk of the pipeline system can be reduced, and the overall stability of the pipeline system can be improved. In addition, the airbag 301 inside the fixed rubber block 300 can absorb the vibration wave, further consume the energy of the vibration, reduce the vibration amplitude, and reduce the noise.

[0039] Optionally, the airbag 301 is arranged at the center of the fixed rubber block 300. In this way, the airbag 301 is arranged at the center of the fixed rubber block 300, and when the internal air pressure is increased, the fixed rubber block 300 can be uniformly pressed toward the surroundings, thereby uniformly improving the hardness of each position of the fixed rubber block 300, thereby synchronously adjusting the vibration frequency of multiple refrigerant pipes 200, so that the vibration frequency of each refrigerant pipe 200 is kept as consistent as possible.

[0040] Optionally, the shape of the airbag 301 is the same as that of the fixed rubber block 300. In this way, when the airbag 301 is located at the center of the fixed rubber block 300, the airbag 301 can be adapted to the fixed rubber block 300, and the inside of the airbag 301 can be evenly transmitted to the fixed rubber block 300 when under pressure, so that the hardness change of each position of the fixed rubber block 300 remains uniform, thereby maintaining a uniform fixing effect on multiple refrigerant pipes 200.

[0041] like Figure 4As shown, optionally, the air pressure regulating mechanism 400 includes: an inflation component 401, an air deflation component 402, an air pressure detection component 403 and an air pressure control component 404. The inflation component 401 is connected to the airbag 301 and is used to inflate the airbag 301; the deflation component 402 is connected to the airbag 301 and is used to release the gas in the airbag 301; the air pressure detection component 403 is arranged in the airbag 301 and is used to detect the air pressure in the airbag 301; the air pressure control component 404 is respectively connected to the inflation component 401, the deflation component 402 and the air pressure detection component 403, and is used to control the inflation component 401 or the deflation component 402 to adjust the air pressure in the airbag 301 according to the actual air pressure detected by the air pressure detection component 403 after obtaining the target air pressure, so that it reaches the target air pressure. In this way, the air pressure regulating mechanism 400 includes an inflation component 401 and a deflation component 402. The air pressure in the airbag 301 is changed by inflating air into the airbag 301 or releasing the gas in the airbag 301, thereby compressing or relaxing the fixed rubber block 300 to change the fixing force of the fixed rubber block 300 on the refrigerant pipe 200, thereby changing the overall vibration frequency of the pipeline system, achieving an effect of adjustable vibration frequency of the pipeline system, so that the vibration frequency of the pipeline system can avoid the vibration frequency of the compressor, thereby avoiding resonance between the pipeline system and the compressor. An air pressure detection component 403 is set in the airbag 301 to obtain the air pressure in the airbag 301 in real time, and feed it back to the air pressure control component 404, so that the air pressure in the airbag 301 can be adjusted more accurately, and the vibration frequency of the pipeline system can be stably controlled to change.

[0042] Optionally, the inflation component 401 includes a gas tank 405 and a small air compressor 406, and the gas tank 405 is connected to the airbag 301 through the small air compressor 406. In this way, the small air compressor 406 is used to compress the gas, so that the airbag 301 can be inflated efficiently and quickly to increase the air pressure in the airbag 301, and the gas stored in the gas tank 405 is used to inflate the airbag 301, so that the stability of the inflated gas can be maintained, and the problem of impurities entering and causing the airbag 301 to be contaminated and oxidized can be avoided.

[0043] Optionally, flame retardant gas is filled in the gas tank 405. In this way, the flame retardant gas is filled in the gas tank 405, which can play a flame retardant effect when there is a fire in the outdoor unit, thereby improving the overall safety of use.

[0044] It can be understood that the flame retardant gas can be carbon dioxide or the like.

[0045] Optionally, an electric-controlled air relief valve is provided on the side of the gas storage tank 405 facing the compressor, and the electric-controlled air relief valve is connected to a temperature sensor, which is provided in the outdoor unit and is used to control the electric-controlled air relief valve to open when the temperature is detected to be higher than a set value. In this way, the open flame in the outdoor unit is detected by the temperature sensor, and when the temperature is too high and a fire is confirmed, the flame-retardant gas in the gas storage tank 405 is controlled to be released, which can achieve a certain fire extinguishing effect and improve the safety of use.

[0046] Optionally, the airbag 301 is connected to the inflation component 401 via a switchable one-way valve, and the deflation component 402 is a pin 407, which can push up the one-way valve to deflate the airbag 301. In this way, by providing a one-way valve, when the airbag 301 is inflated, the reverse outflow of the air can be prevented, and the air pressure in the airbag 301 can be maintained stably for a long time. When deflation is required, the pin 407 can be controlled to push up the one-way valve to deflate the airbag. The overall structure is simple and has high stability.

[0047] Optionally, the vibration sensor 500 is provided with a plurality of sensing parts, and is respectively arranged on a plurality of refrigerant pipes 200 and a fixed rubber block 300. In this way, the vibrations on the refrigerant pipe 200 and the fixed rubber block 300 can be detected by the plurality of sensing parts, and the vibration frequencies of each part can be integrated to improve the accuracy of the detection.

[0048] Optionally, the fixing rubber block 300 is provided with a plurality of pipe fixing holes 302, and the pipe fixing holes 302 are used to fix the refrigerant pipe 200. In this way, the refrigerant pipe 200 can pass through the pipe fixing holes 302 on the fixing rubber block 300, so as to better fix the refrigerant pipe 200, and the refrigerant pipe 200 is fixed by a sleeve connection method, so that the connection between the fixing rubber block 300 and the refrigerant pipe 200 is more flexible and easy to adjust.

[0049] Optionally, the fixing rubber block 300 is a polygonal structure, and the pipe fixing holes 302 are arranged at the corners of the polygonal structure. In this way, the refrigerant pipe 200 is fixed at the corners of the fixing rubber block 300, and the refrigerant pipe 200 can be fixed from the position between multiple refrigerant pipes 200, reducing the space occupied by the fixing rubber block 300, and separating multiple refrigerant pipes 200 by a certain distance to prevent the refrigerant pipes 200 from affecting each other.

[0050] The shape of the fixing rubber block 300 is related to the number of refrigerant pipes 200 it fixes. For example, when the fixing rubber block 300 is used to fix three refrigerant pipes 200, it has a triangular structure and uses the positions of the three vertices to fix the refrigerant pipes 200 respectively.

[0051] Optionally, the pipeline fixing hole 302 is arranged at the edge of the fixing rubber block 300 and has an opening 303 facing the edge of the fixing rubber block 300. In this way, the refrigerant pipe 200 is conveniently inserted into the pipeline fixing hole 302 through the opening 303 on the edge of the fixing rubber block 300, thereby improving the convenience of connection between the refrigerant pipe 200 and the fixing rubber block 300 and facilitating the removal and installation of the fixing rubber block 300.

[0052] Optionally, the pipeline fixing hole 302 is circular, and its diameter is less than or equal to the diameter of the refrigerant pipe 200. In this way, the refrigerant fixing hole 302 can be filled with the refrigerant pipe 200 fixed in it, and the elasticity of the fixing rubber block 300 is fully utilized to improve the fixing effect of the refrigerant pipe 200.

[0053] Combination Figure 5 As shown, the embodiment of the present disclosure provides a control method for preventing resonance of a pipeline system, including:

[0054] S01, determining the operating frequency of the compressor;

[0055] S02, obtaining the vibration frequency of the pipeline system;

[0056] S03, controlling the air pressure regulating mechanism to regulate the air pressure in the airbag according to the difference between the operating frequency of the compressor and the vibration frequency of the pipeline system.

[0057] By adopting the control method for preventing resonance of the pipeline system provided in the embodiment of the present invention, the vibration frequencies of the refrigerant pipe and the compressor can be determined in real time, and the air pressure in the inner cavity of the fixed rubber block can be adjusted according to the frequencies of the refrigerant pipe and the compressor, thereby changing the vibration frequency of the pipeline system so that the vibration frequency of the pipeline system avoids the frequency of the compressor, thereby avoiding resonance between the refrigerant pipe and the compressor, which can effectively reduce the vibration amplitude of the refrigerant pipe, reduce noise, eliminate the stress risk of the pipeline system, and improve the overall stability of the pipeline system.

[0058] Optionally, S01, obtaining the operating frequency of the compressor includes: connecting the compressor frequency determination module to the processor of the refrigeration equipment, and determining the current operating frequency of the compressor by extracting its system operation data. In this way, the operating frequency of the compressor can be obtained more accurately and conveniently. Generally, the vibration frequency of the compressor is directly related to its operating frequency. Based on this, the vibration frequency of the compressor can be efficiently determined, thereby facilitating the control of the vibration frequency of the pipeline system to avoid the vibration frequency of the compressor, thereby avoiding the resonance of the pipeline system.

[0059] It can be understood that the operating frequency of the compressor can also be directly obtained by setting a sensor on the compressor.

[0060] Optionally, S02, obtaining the vibration frequency of the pipeline system includes: in the case where multiple sensing parts of the vibration sensors are provided on the pipeline system, obtaining the vibration frequency data detected by the multiple sensing parts, and 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 the vibration frequency data of multiple positions on the pipeline system and calculating the average value thereof, the overall vibration frequency of the pipeline system can be more accurately reflected, and the measurement error can be reduced.

[0061] like Figure 6 As shown, optionally, S03, according to the difference between the operating frequency of the compressor and the vibration frequency of the pipeline system, controlling the air pressure regulating mechanism to regulate the air pressure in the airbag includes:

[0062] S31, calculating the difference between the operating frequency of the compressor and the vibration frequency of the pipeline system;

[0063] S32, when it is determined that the difference between the operating frequency of the compressor and the vibration frequency of the pipeline system is greater than or equal to a first threshold, controlling the air pressure regulating mechanism to maintain the current air pressure in the airbag;

[0064] S33, when it is determined that the difference between the operating frequency of the compressor and the vibration frequency of the pipeline system is less than a first threshold, control the air pressure regulating mechanism to increase or decrease the air pressure in the airbag.

[0065] In this way, the resonance between the compressor and the pipeline system means that the vibration frequencies of the two are the same. Therefore, taking into account the detection error of the vibration sensor, when it is detected that the difference between the two is greater than or equal to the first threshold, it means that there is an obvious difference in the vibration frequencies between the two, and no resonance will occur. At this time, maintaining the current air pressure of the airbag in the fixed rubber block can avoid the resonance between the compressor and the pipeline system. When the difference between the two is less than the first preset value, it means that the vibration frequencies between the two are relatively close. At this time, the possibility of resonance between the compressor and the pipeline system is higher. At this time, by increasing or decreasing the air pressure of the airbag in the fixed rubber block, the vibration frequency of the pipeline system can be changed, so that the vibration frequencies between the two are widened to a certain extent, thereby effectively avoiding the resonance between the compressor and the pipeline system, avoiding excessive vibration amplitude, effectively reducing noise, eliminating the stress risk of the pipeline system, and improving the overall stability of the pipeline system.

[0066] Optionally, the value of the first threshold is determined according to the operating frequency of the compressor. In this way, since the vibration of the compressor is the source of the vibration and its vibration frequency cannot be adjusted, the first threshold is determined according to the operating frequency of the compressor, and the vibration frequency of the pipeline system is controlled accordingly, which can effectively prevent the vibration frequency of the pipeline system from approaching the vibration frequency of the compressor, reduce the risk of resonance, and improve the stability of the overall pipeline system.

[0067] Optionally, the first threshold is 1% to 3% of the operating frequency of the compressor. Preferably, the first threshold is 2% of the operating frequency of the compressor. In this way, under normal circumstances, when the vibration frequency of two objects is close to within 3%, there will be a risk of resonance. Therefore, the first threshold is set within 1% to 3%. When the difference between the operating frequency of the compressor and the vibration frequency of the pipeline system is less than 1% to 3% of the operating frequency of the compressor, the airbag adjustment mechanism is controlled to adjust the air pressure of the airbag of the fixed rubber block, so that the vibration frequency of the pipeline system changes, better avoiding resonance between the compressor and the pipeline system, eliminating the stress risk of the pipeline system, and improving the stability of the pipeline system.

[0068] For example, when the first threshold is 2% of the operating frequency of the compressor, and the operating frequency of the compressor is 50 Hz, the value of the first threshold is 1 Hz.

[0069] like Figure 7 As shown, optionally, in S33, when it is determined that the difference between the operating frequency of the compressor and the vibration frequency of the pipeline system is less than a first threshold, controlling the air pressure regulating mechanism to increase or decrease the air pressure in the airbag includes:

[0070] S34, obtaining the current air pressure of the airbag in the fixed rubber block;

[0071] S35, when it is determined that the current air pressure of the airbag in the fixed rubber block is in the first preset range, controlling the air pressure regulating mechanism to increase the air pressure in the airbag;

[0072] S36, when it is determined that the current air pressure of the airbag is in the second preset area, the air pressure regulating mechanism reduces the air pressure in the airbag.

[0073] In this way, when it is necessary to adjust the air pressure of the airbag in the fixed rubber block, the current air pressure of the airbag can be obtained, and according to the range of the air pressure in the airbag, the airbag adjustment mechanism can be controlled to increase or decrease the air pressure of the airbag. When the current air pressure of the airbag is high, the air pressure of the airbag is lowered, and when the current air pressure of the airbag is low, the air pressure of the airbag is increased. The air pressure of the airbag can be reasonably adjusted within the adjustable range, thereby changing the vibration frequency of the pipeline system, preventing resonance between the pipeline system and the compressor, and preventing the air pressure of the airbag of the fixed rubber block from exceeding its adjustable range when adjusting the air pressure, causing damage to the fixed rubber block or failure of the adjustment.

[0074] Optionally, the adjustable range of the air pressure of the airbag in the fixed rubber block is determined, the first preset area is the first half of the adjustable range of the air pressure of the airbag in the fixed rubber block, and the second preset area is the second half of the adjustable range of the air pressure of the airbag in the fixed rubber block, wherein the range of the first preset area is larger than the range of the second preset area. In this way, the first preset area is the first half of the adjustable range of the air pressure of the airbag, so when the current air pressure is in the first preset area, it means that the air pressure of the airbag has room to be increased, so the air pressure of the airbag is controlled to increase, and conversely, when it is in the second preset area, the air pressure of the airbag can be controlled to decrease, wherein the range of the first preset area is larger than the second preset area, which can increase the probability of increasing the air pressure of the airbag during the adjustment stage, give priority to increasing the air pressure of the airbag, and can improve the fixing effect of the refrigerant pipe.

[0075] Optionally, the adjustable air pressure range of the airbag is determined, the first preset area is the first four fifths of the adjustable air pressure range of the airbag, and the second preset area is the last one fifth of the adjustable air pressure range of the airbag. In this way, by determining the adjustable air pressure range of the airbag, the adjustment strategy for the airbag is controlled. When the current air pressure of the airbag is in the first four-fifths of the adjustable air pressure range, it means that the air pressure of the airbag still has room for upward adjustment. Therefore, the air pressure of the airbag is increased first, which can change the vibration frequency of the pipeline system and widen the gap between it and the vibration frequency of the compressor to avoid resonance. At the same time, increasing the air pressure of the airbag can further squeeze the fixed rubber block to increase the fixing force on the refrigerant pipe, reduce the vibration amplitude of the refrigerant pipe, and better reduce shock and noise. When the current air pressure of the airbag is in the last fifth of its adjustable air pressure range, it means that the air pressure of the airbag is about to reach the upper limit. Continuing to increase it at this time may easily cause damage to the fixed rubber block, or the adjustment demand may not be met after the air pressure upper limit of the airbag is reached. Therefore, the air pressure of the airbag is reduced first to make its adjustable range larger, which can better ensure that the vibration frequency of the pipeline system is widened a certain distance from the vibration frequency of the compressor to avoid resonance.

[0076] It can be understood that the vibration frequency of the pipeline system referred to above refers to the average value of the vibration frequencies at multiple positions of the refrigerant pipe and the fixed rubber block.

[0077] like Figure 8 As shown, another control method for preventing resonance of a pipeline system provided by the embodiment of the present disclosure includes:

[0078] S04, controlling the airbag adjustment mechanism to adjust the air pressure of the airbag to the maximum value of its adjustable air pressure range;

[0079] S05, when it is determined that the difference between the operating frequency of the compressor and the vibration frequency of the pipeline system is less than a first threshold, control the airbag adjustment mechanism to reduce the air pressure of the airbag.

[0080] In this way, the initial air pressure of the airbag of the fixed rubber block is set to the maximum value, which can provide a higher fixing force for the refrigerant pipe during the startup phase of the compressor, effectively suppress the vibration of the refrigerant pipe, and enable the fixed rubber block to exert the best fixing force when there is no risk of resonance between the pipeline system and the compressor, thereby improving the overall stability of the pipeline system. When the difference between the operating frequency of the compressor and the vibration frequency of the pipeline system is less than the first threshold value, and it is determined that there is a risk of resonance between the compressor and the pipeline system, the vibration frequency of the refrigerant pipe is changed by lowering the air pressure of the airbag, thereby widening the gap between the vibration frequency of the refrigerant pipe and the compressor, thereby avoiding resonance between the two.
