Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of household appliances, for example to a pipeline system, a control method for preventing resonance of the pipeline system, and a storage medium. BACKGROUND

[0002] At present, in the refrigeration equipment, the compressor is mostly used in combination with the pipeline system to carry out refrigeration. Due to the vibration generated in the operation process of the compressor, the whole pipeline system will be vibrated, which on the one hand leads to excessive noise, and on the other hand, the long-time vibration easily causes the interface to be loose, affecting the stability of the use of the whole pipeline system.

[0003] In the related art, in order to reduce the vibration of the pipeline system, a fixing assembly is mostly used to improve the fixing force of the pipeline system, but this still cannot avoid the vibration of the pipeline system, and the compressor at the present stage is mostly a variable frequency compressor. With the change of the working frequency of the compressor, the vibration frequency changes, which easily causes resonance between the compressor and the pipeline system, and further aggravates the vibration amplitude of the pipeline system, generates excessive noise, and reduces the service life of the whole pipeline system.

[0004] It can be seen that how to avoid the resonance between the compressor and the pipeline system, reduce the vibration amplitude of the pipeline system, improve the stability of the use of the whole pipeline system, and reduce the noise of the pipeline system, has become a technical problem to be solved by the person skilled in the art.

[0005] It should be noted that the information disclosed in the above background section is only used to strengthen the understanding of the background of the present application, and therefore can include information which does not constitute prior art known to those of ordinary skill in the art. SUMMARY

[0006] In order to have a basic understanding of some aspects of the disclosed embodiments, the following is a simple summary.

[0008] In some embodiments, the pipeline system comprises: a plurality of refrigerant pipes, a fixing block, an air pressure adjusting mechanism, a vibration sensor, a compressor frequency determining module and a controller assembly. The fixing block is fixedly connected with the plurality of refrigerant pipes, and the fixing block is internally provided with an air bag. The air pressure adjusting mechanism is in communication with the air bag and is used to control the air pressure in the air bag. The vibration sensor is arranged on the refrigerant pipe and / or the fixing block and is used to detect the vibration frequency of the pipeline system. The compressor frequency determining module is used to obtain the operating frequency of the compressor. The controller assembly is connected with the air pressure adjusting mechanism, the vibration sensor and the compressor frequency determining module, and is used to control the air pressure adjusting mechanism to adjust the air pressure of the air bag of the fixing block according to the vibration frequency of the pipeline system detected by the vibration sensor and the operating frequency of the compressor obtained by the compressor frequency determining module.

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

[0015] The fixing block is used to fix the refrigerant pipe, so as to reduce the vibration amplitude of the refrigerant pipe. The air bag is arranged in the fixing block, and the air pressure in the air bag is adjusted, so as to adjust the tightness of the fixing block. The fixing force of the fixing block with different tightnesses on the refrigerant pipe is different, so as to change the vibration frequency of the pipeline system. During the adjustment process, the vibration frequencies of the refrigerant pipe and the compressor are determined in real time by the vibration sensor and the compressor frequency determining module, and then the air pressure of the air bag in the fixing block is adjusted according to the frequencies of the refrigerant pipe and the compressor. The tightness of the fixing block is changed by adjusting the air pressure of the air bag, and then the vibration frequencies of the fixing block and the refrigerant pipe fixed by the fixing block are changed, so that the vibration frequency of the pipeline system avoids the frequency of the compressor, and resonance is avoided between the refrigerant pipe and the compressor.

[0042] Optionally, the air charging assembly 401 comprises a gas storage tank 405 and a small air compressor 406, and the gas storage tank 405 is in communication with the air bag 301 through the small air compressor 406. In this way, the small air compressor 406 is used to compress air, so that air can be charged into the air bag 301 efficiently and quickly, the air pressure in the air bag 301 is improved, and the gas storage tank 405 is used to store air to charge the air bag 301, so that the stability of the charged air can be maintained, and impurities can be prevented from entering to cause problems such as internal pollution and oxidation of the air bag 301.

[0045] Optionally, the gas tank 405 is provided with an electrically controlled air release valve on the side facing the compressor, and the electrically controlled air release valve is connected with a temperature sensor arranged in the outdoor unit and used for controlling the electrically controlled air release valve to open when the temperature is higher than a set value. In this way, the temperature sensor is used to detect the open fire in the outdoor unit, and the fire extinguishing gas in the gas tank 405 is released when the temperature is too high to determine the fire condition, so that the fire extinguishing effect can be achieved and the safety in use is improved.

[0046] Optionally, the air bag 301 is connected with the inflation assembly 401 through a switchable one-way valve, and the air release assembly 402 is a thimble 407 capable of lifting the one-way valve to deflate the air bag 301.

[0047] Optionally, the vibration sensor 500 is provided with a plurality of sensing portions arranged on the plurality of refrigerant pipes 200 and the fixing block 300.

[0048] Optionally, the fixing block 300 is provided with a plurality of pipeline fixing holes 302 for fixing the refrigerant pipes 200. In this way, the refrigerant pipes 200 can pass through the pipeline fixing holes 302 of the fixing block 300 to better fix the refrigerant pipes 200, and the refrigerant pipes 200 are fixed in a sleeved connection manner, so that the connection between the fixing block 300 and the refrigerant pipes 200 is more flexible and convenient to adjust.

[0049] Optionally, the fixing block 300 is a polygonal structure, and the pipeline fixing holes 302 are arranged at the corners of the polygonal structure.

[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.

[0052] Optionally, the pipeline fixing hole 302 is circular and has a diameter less than or equal to that of the refrigerant pipe 200.

[0053] In combination with Figure 5 As shown in the drawings, the embodiment of the present disclosure provides a control method for preventing resonance of a pipeline system, which comprises the following steps:

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

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

[0056] S03, controlling a gas pressure adjusting mechanism to adjust the gas pressure in an air bag according to the difference between the operating frequency of the compressor and the vibration frequency of the pipeline system.

[0057] By using the control method for preventing resonance of the pipeline system provided by the embodiment of the present disclosure, the vibration frequencies of the refrigerant pipe and the compressor can be determined in real time, and then the gas pressure in the inner cavity of the fixing rubber block is adjusted according to the frequencies of the refrigerant pipe and the compressor, so as to change the vibration frequency of the pipeline system, avoid the vibration frequency of the pipeline system from the frequency of the compressor, and avoid resonance between the refrigerant pipe and the compressor. The vibration amplitude of the refrigerant pipe can be effectively reduced, the noise can be reduced, the stress risk of the pipeline system can be eliminated, and the stability of the whole pipeline system can be improved.

[0058] Optionally, S01, acquiring the operating frequency of the compressor comprises: connecting a compressor frequency determination module with a processor of the refrigeration equipment, and determining the current operating frequency of the compressor by extracting system operation data. In this way, the operating frequency of the compressor can be more accurately and simply acquired. Generally, the vibration frequency of the compressor is directly related to its operating frequency, so the vibration frequency of the compressor can be efficiently determined, and then the vibration frequency of the pipeline system can be controlled to avoid the vibration frequency of the compressor, and the resonance of the pipeline system can be avoided.

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

[0060] Optionally, the acquiring the vibration frequency of the pipeline system comprises: in the case that the plurality of sensing portions of the vibration sensors are arranged on the pipeline system, acquiring vibration frequency data detected by the plurality of sensing portions, and calculating an average value of the plurality of 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 a plurality of positions on the pipeline system and calculating the average value, the vibration frequency of the entire pipeline system can be more accurately reflected, and the measurement error can be reduced.

[0061] As shown in Figure 6 Optionally, S03, controlling the air pressure adjusting mechanism to adjust the air pressure in the air bag according to the difference between the operating frequency of the compressor and the vibration frequency of the pipeline system comprises:

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

[0063] S32, in the case that 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 value, controlling the air pressure adjusting mechanism to maintain the current air pressure in the air bag;

[0064] S33, in the case that the difference between the operating frequency of the compressor and the vibration frequency of the pipeline system is less than the first threshold value, controlling the air pressure adjusting mechanism to increase or decrease the air pressure in the air bag.

[0065] In this way, the resonance between the compressor and the pipeline system refers to the same vibration frequency of the two, so considering 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 value, it indicates that there is a significant difference in the vibration frequency between the two, and resonance will not occur, at this time the current air pressure in the air bag of the fixed block is maintained, which can avoid resonance between the compressor and the pipeline system. When the difference between the two is less than the first preset value, it indicates that the vibration frequencies of the two are close, at this time the possibility of resonance between the compressor and the pipeline system is high, at this time the air pressure in the air bag of the fixed block is increased or decreased, which can change the vibration frequency of the pipeline system, so as to pull apart the vibration frequency between the two, and further effectively avoid resonance between the compressor and the pipeline system, avoid excessive vibration amplitude, effectively reduce noise, eliminate the stress risk of the pipeline system, and improve the stability of the entire pipeline system.

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

[0067] 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 airbag adjustment mechanism adjusts the air pressure of the fixed rubber 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.

[0068] 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.

[0069] 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 pressure regulating mechanism is controlled to increase or decrease the pressure inside the airbag, including:

[0070] S34, obtain the current air pressure of the airbag inside the fixed rubber block;

[0071] S35, if the current air pressure of the airbag inside the fixed rubber block is determined to be in the first preset area, control the air pressure regulating mechanism to increase the air pressure inside the airbag;

[0072] S36, if the current air pressure of the airbag is determined to be in the second preset zone, the air pressure regulating mechanism reduces the air pressure inside the airbag.

[0073] In this way, when it is necessary to adjust the air pressure of the airbag inside the fixed rubber block, the current air pressure of the airbag can be obtained. Based on the range of air pressure inside the airbag, the airbag adjustment mechanism can be controlled to increase or decrease the air pressure of the airbag. If the current air pressure of the airbag is high, the air pressure of the airbag is decreased; if the current air pressure of the airbag is low, the air pressure of the airbag is increased. This allows for reasonable adjustment of the air pressure of the airbag within the adjustable range, thereby changing the vibration frequency of the piping system, preventing resonance between the piping system and the compressor, and preventing damage to the fixed rubber block or adjustment failure caused by exceeding its adjustable range when adjusting the air pressure of the airbag inside the fixed rubber block.

[0074] Optionally, a range of the air pressure of the air bag in the fixed rubber block is determined, the first preset region is a first half region of the range of the air pressure of the air bag in the fixed rubber block, and the second preset region is a second half region of the range of the air pressure of the air bag in the fixed rubber block, wherein the range of the first preset region is greater than the range of the second preset region. In this way, the first preset region is a first half region of the range of the air pressure of the air bag, and thus, when the current air pressure is in the first preset region, it indicates that the air pressure of the air bag has a space for increase, and thus, the air pressure of the air bag is increased. Conversely, when the current air pressure is in the second preset region, the air pressure of the air bag is decreased. The range of the first preset region being greater than the range of the second preset region can increase the probability of increasing the air pressure of the air bag in the adjustment stage, preferentially increase the air pressure of the air bag, and improve the fixing effect on the refrigerant pipe.

[0075] Optionally, a range of the air pressure of the air bag is determined, the first preset region is a first four-fifths of the range of the air pressure of the air bag, and the second preset region is a last one-fifth of the range of the air pressure of the air bag. In this way, by determining the range of the air pressure of the air bag, the adjustment strategy for the air bag is controlled. When the current air pressure of the air bag is in the first four-fifths of the range of the air pressure, it indicates that the air pressure of the air bag still has a space for increase, and thus, the air pressure of the air bag is preferentially increased. This can change the vibration frequency of the pipeline system, so as to pull apart the vibration frequency of the compressor, avoid resonance, and further increase the air pressure of the air bag to further press the fixed rubber block and improve the fixing force on the refrigerant pipe, thereby reducing the vibration amplitude of the refrigerant pipe and better reducing vibration and noise. When the current air pressure of the air bag is in the last one-fifth of the range of the air pressure, it indicates that the air pressure of the air bag is about to reach the upper limit. At this time, if the air pressure of the air bag is continuously increased, the fixed rubber block is likely to be damaged. Even if the air pressure of the air bag reaches the upper limit, the adjustment requirement cannot still be met. Therefore, the air pressure of the air bag is preferentially decreased, so that the adjustable range of the air pressure of the air bag is larger, and the vibration frequency of the pipeline system can be better pulled apart 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 is an average value of the vibration frequencies at multiple positions of the refrigerant pipe and the fixed rubber block.

[0077] As shown in FIG. 1, the embodiment of the present disclosure provides another control method for preventing resonance of a pipeline system, which comprises the following steps. Figure 8

[0078] S04, controlling the air bag adjustment mechanism to adjust the air pressure of the air bag to a maximum value in the range of the air pressure of the air bag.

[0079] S05, when the difference between the operating frequency of the compressor and the vibration frequency of the pipeline system is less than a first threshold value, controlling the air bag adjustment mechanism to decrease the air pressure of the air bag.

[0080] ​Thus, the initial air pressure of the air bag of the fixing block is set to the maximum value, a higher fixing force can be provided to the refrigerant pipe during the starting stage of the compressor, the vibration of the refrigerant pipe is effectively inhibited, the fixing block can exert the optimal fixing force in the case that there is no resonance risk between the pipeline system and the compressor, and the stability of the entire pipeline system is improved. 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, it is determined that there is a resonance risk between the compressor and the pipeline system, the vibration frequency of the refrigerant pipe is changed by adjusting the air pressure of the air bag, so as to make the vibration frequency of the compressor and the vibration frequency of the refrigerant pipe different, and resonance between the compressor and the refrigerant pipe is avoided.
