Description

Technical Field

[0001] The present application relates to the field of household appliance technology, for example, to a rubber block and a piping system for fixing a refrigerant pipe. 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 disclosed embodiments provide a rubber block and a piping system for fixing a refrigerant pipe, so as to solve the technical problem that as the operating frequency of the compressor changes, its vibration frequency changes, which easily resonates with the piping system, thereby aggravating the vibration amplitude of the piping system.

[0008] In some embodiments, a rubber block for fixing a refrigerant pipe is used to fix a plurality of refrigerant pipes, and includes a rubber block body and an expansion module. The rubber block body is fixedly connected to the plurality of refrigerant pipes; the expansion module is disposed in the rubber block body, and can adjust the structural rigidity of the rubber block body by expanding and squeezing the rubber block body.

[0009] In some embodiments, the piping system includes the rubber block for fixing the refrigerant pipe according to any one of the above embodiments.

[0010] The rubber block and the piping system for fixing the refrigerant pipe provided in the embodiments of the present disclosure can achieve the following technical effects:

[0011] The refrigerant pipe is fixed by the rubber block body to reduce the vibration amplitude of the refrigerant pipe, and an expansion module is arranged inside the rubber block body to adjust the structural stiffness of the rubber block body. When the expansion module expands, it squeezes the rubber block body from the inside to tighten the rubber block body and improve the structural strength of the rubber block body. On the contrary, the degree of tightening of the rubber block body by the expansion module is low before expansion. At this time, the structural strength of the rubber block body is low and the whole body is soft. The rubber block bodies with different structural strengths have different fixing forces on the refrigerant pipe, which can change the vibration frequency of the refrigerant pipe and make the vibration frequency of the refrigerant pipe avoid 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 the stress risk of the overall pipeline system, and improve the overall stability of the pipeline system.

[0031] Combination Figure 1-7 As shown, the embodiment of the present disclosure provides a rubber block for fixing a refrigerant pipe, which is used to fix a plurality of refrigerant pipes 300, and includes: a rubber block body 100 and an expansion module 200. The rubber block body 100 is fixedly connected to the plurality of refrigerant pipes 300; the expansion module 200 is disposed in the rubber block body 100, and can adjust the structural rigidity of the rubber block body 100 by expanding and squeezing the rubber block body 100.

[0032] By using the rubber block for fixing the refrigerant pipe provided by the embodiment of the present disclosure, the refrigerant pipe 300 is fixed by the rubber block main body 100 to reduce the vibration amplitude of the refrigerant pipe 300, and an expansion module 200 is arranged inside the rubber block main body 100 to adjust the structural stiffness of the rubber block main body 100. When the expansion module 200 expands, it squeezes the rubber block main body 100 from the inside to tighten the rubber block main body 100 and improve the structural strength of the rubber block main body 100. On the contrary, the degree of tightening of the rubber block main body 100 by the expansion module 200 before expansion is low. At this time, the structural strength of the rubber block main body 100 is low and the whole is soft. The rubber block main body 100 with different structural strengths has different fixing forces on the refrigerant pipe 300, thereby changing the vibration frequency of the refrigerant pipe 300, so that the vibration frequency of the refrigerant pipe 300 avoids the frequency of the compressor, avoids resonance between the refrigerant pipe 300 and the compressor, and can effectively reduce the vibration amplitude of the refrigerant pipe 300, reduce the stress risk of the overall pipeline system, and improve the overall stability of the pipeline system.

[0033] Optionally, the expansion module 200 is a block structure of a shape memory polymer material. In this way, by utilizing the obvious thermal expansion and contraction effect of the shape memory polymer material, when resonance occurs between the compressor and the refrigerant pipe 300, the vibration amplitude increases significantly. At this time, due to the enhanced vibration, the friction between the rubber block body 100 and the expansion module 200 increases, and the temperature rises rapidly, thereby causing the shape memory polymer material to expand thermally, squeezing and tightening the rubber block body 100 from the inside, improving the structural rigidity of the rubber block body 100, changing the fixing force of the rubber block body 100 to the refrigerant pipe 300, and thereby changing the vibration frequency of the refrigerant pipe 300, avoiding the operating frequency of the compressor, and making the frequencies of the two have a certain gap, avoiding the resonance between the two. By setting the expansion module 200 as a shape memory polymer material, the energy of the resonance itself can be used to solve the resonance risk when resonance occurs, without the need for electronic control interference, with a simple structure, significant effect, and high stability.

[0034] It can be understood that the shape memory polymer material is a thermotropic shape memory polymer material, which can maintain a certain shape at room temperature and return to its original shape after the temperature changes. Its specific structure is a technology well known to those skilled in the art and will not be described in detail here.

[0035] Optionally, the expansion module 200 is disposed at the center of the rubber block body 100. In this way, the expansion module 200 is disposed at the center of the rubber block body 100, and when the internal air pressure is increased, the rubber block body 100 can be uniformly pressed toward the periphery, thereby uniformly improving the hardness of each position of the rubber block body 100, thereby synchronously adjusting the vibration frequencies of the multiple refrigerant pipes 300, so that the vibration frequencies of the refrigerant pipes 300 are kept as consistent as possible.

[0036] It is understandable that the expansion module 200 can also be wrapped around the circumference of the rubber block body 100. In this way, the expansion module 200 is wrapped around the circumference of the rubber block body 100, and when it expands, it will also uniformly squeeze the rubber block body 100 inward. Therefore, other methods that can uniformly squeeze the rubber block body 100 when the expansion module 200 is deformed can be applied to this solution, and its main function is to uniformly tighten each position of the rubber block body 100 and uniformly change the structural rigidity of the rubber block body 100.

[0037] In some embodiments, the shape of the expansion module 200 is the same as that of the rubber block body 100. In this way, when the expansion module 200 is located at the center of the rubber block body 100, the expansion module 200 can be adapted to the rubber block body 100, and the internal pressure can be evenly transmitted to the rubber block body 100 under pressure, so that the structural rigidity changes of various positions of the rubber block body 100 remain uniform, thereby maintaining a uniform fixing effect on multiple refrigerant pipes 300.

[0038] In other embodiments, the expansion module 200 is circular. In this way, the circular expansion module 200 can apply uniform force to its surroundings when expanding outward, and the expansion distance in each direction remains the same, which can effectively improve the uniformity of the force in each direction on the rubber block body 100, thereby maintaining the uniformity of the fixing effect of each position on the refrigerant pipe 300, so that the multiple refrigerant pipes 300 form a whole that vibrates together.

[0039] like Figure 3 As shown, optionally, a mounting hole 101 penetrating the rubber block body 100 is provided on the rubber block body 100, and the expansion module 200 is arranged in the mounting hole 101, and the expansion module 200 directly contacts the external space of the rubber block body 100 through the mounting hole 101. In this way, when the expansion module 200 is a shape memory polymer material, it can expand rapidly when heated to squeeze the rubber block body 100, and the expansion module 200 is directly in contact with the external space of the rubber block body 100, which can improve the heat dissipation effect of the expansion module 200. After the heat near the expansion module 200 stops supplying heat, the expansion module 200 can be quickly cooled down and quickly shrunk, thereby improving the response speed of adjusting the tightness of the rubber block body 100, quickly changing the vibration frequency of the refrigerant pipe 300 fixed to the rubber block body 100, and improving the speed of adjusting the vibration frequency of the refrigerant pipe 300, thereby reducing the risk of resonance between the pipeline system and the compressor.

[0040] Optionally, the inner wall of the mounting hole 101 is provided with an annular embedding groove 102, and the circumference of the expansion module 200 is embedded and installed in the annular embedding groove 102. In this way, the expansion module 200 can be better installed and fixed, and when the mounting hole 101 passes through the rubber block body 100, the expansion module 200 is fixed by the annular embedding groove 102, which can prevent the expansion module 200 from being loosely fixed to the mounting hole 101 when the expansion module 200 contracts, causing the expansion module 200 to fall off, thereby affecting the overall service life.

[0041] Optionally, a heating component 201 is provided inside or on the side of the expansion module 200. In this way, the heating component 201 is provided inside or on the side of the expansion module 200, so as to heat the expansion module 200, and then expand it by heat. The heating component 201 provides heat to the expansion component, so that it can squeeze the rubber block body 100 after the expansion by heat, so that the rubber block body 100 is squeezed and tightened, and the structural strength is increased, and then the vibration frequency of the fixed refrigerant pipe 300 can be changed, so that the vibration frequency of the refrigerant pipe 300 avoids the frequency of the compressor, and the resonance between the refrigerant pipe 300 and the compressor is avoided, which can effectively reduce the vibration amplitude of the refrigerant pipe 300, reduce the stress risk of the overall pipeline system, and improve the overall stability of the pipeline system.

[0042] In some embodiments, the heating component 201 is an electric heating plate, which can generate heat in a controlled manner, and then heat the expansion module 200 made of shape memory polymer material to expand it, thereby changing the squeezing force on the rubber block body 100, adjusting the fixing force of the rubber block body 100 on the refrigerant tube 300, and changing the vibration frequency of the refrigerant tube 300 by electric control to avoid the vibration frequency of the compressor and avoid resonance between the two. In this way, by heating and controlling the expansion module 200 in the form of electric heating, the expansion of the expansion module 200 can be more intelligently regulated, and the fixing force of the refrigerant tube 300 can be better controlled, the vibration frequency of the refrigerant tube 300 can be changed, and the resonance phenomenon between the refrigerant tube 300 and the compressor can be avoided, thereby reducing the stress risk of the overall pipeline system.

[0043] Optionally, the heating component 201 is a friction heating structure, and an empty groove 202 is provided inside the expansion module 200, and the friction heating structure is arranged in the empty groove 202. In this way, when resonance occurs between the refrigerant pipe 300 and the compressor, the vibration amplitude increases, which can drive the friction heating structure to generate heat by friction, and use the generated heat to quickly heat the expansion module 200 to make it expand. When resonance occurs, it can quickly respond to change the vibration frequency of the refrigerant pipe 300, and then quickly eliminate the resonance with the compressor, which can automatically avoid long-term resonance between the refrigerant pipe 300 and the compressor, improve the stability of the pipeline system, and reduce the stress risk of the overall pipeline system.

[0044] like Figure 4 As shown, optionally, the friction heating structure includes: a friction cavity 203 and a friction plate 204. The friction cavity 203 is arranged on one side of the expansion module 200, and the friction plate 204 is arranged in the friction cavity 203, wherein the interior of the friction cavity 203 and the surface of the friction plate 204 are rough surfaces. In this way, the friction plate 204 is wrapped by the friction cavity 203, and when the friction heating structure as a whole vibrates, the friction plate 204 will vibrate in the friction cavity 203, so that friction occurs between the two, and then the friction between the two generates heat, which has the effect of heating the expansion module 200.

[0045] Optionally, an outer side wall of the friction cavity 203 is attached to the expansion module 200. In this way, the heat exchange effect between the friction cavity 203 and the expansion module 200 can be improved, so that the heat generated in the friction cavity 203 can be quickly transferred to the expansion module 200, and the expansion module 200 can be heated more efficiently, the corresponding speed of the expansion module 200 to produce changes is increased, and heat loss is avoided, thereby improving the sensitivity of the expansion module 200 to heating by frictional heat.

[0046] Optionally, the friction cavity 203 is made of a high thermal conductivity material. Preferably, the high thermal conductivity material is copper. In this way, by improving the thermal conductivity of the friction cavity 203 itself, the heat generated by the friction cavity 203 can be quickly transferred to the expansion module 200, thereby improving the utilization efficiency of the heat.

[0047] Optionally, a fixing hole 103 is provided at a corner of the rubber block body 100, and a notch 104 is provided on the fixing hole 103 that passes through the outside of the rubber block body 100. The refrigerant pipe 300 is conveniently inserted into the fixing hole 103 through the notch 104 on the edge of the rubber block body 100, thereby improving the convenience of connection between the refrigerant pipe 300 and the rubber block body 100 and facilitating the disassembly and installation of the rubber block body 100.

[0048] Optionally, the rubber block body 100 is a polygonal structure, and the fixing holes 103 are arranged at the corners of the polygonal structure. In this way, the refrigerant tube 300 is fixed at the corners of the rubber block body 100, and the refrigerant tube 300 can be fixed from the position between the multiple refrigerant tubes 300, thereby reducing the space occupied by the rubber block body 100, and separating the multiple refrigerant tubes 300 by a certain distance to prevent the refrigerant tubes 300 from affecting each other.

[0049] The shape of the rubber block body 100 is related to the number of refrigerant tubes 300 fixed by it. For example, when the rubber block body 100 is used to fix three refrigerant tubes 300, it has a triangular structure and uses the positions of the three vertices to fix the refrigerant tubes 300 respectively.

[0050] Combination Figure 5-7 As shown, in some optional embodiments, the expansion module 200 is an air bag 205 disposed in the rubber block body 100. In this way, by controlling the inflation or deflation of the air bag 205, the supporting effect on the rubber block body 100 is changed, thereby changing the overall structural stress of the rubber block body 100, and changing the fixing force of the refrigerant pipe 300, thereby adjusting the vibration frequency of the refrigerant pipe 300, so that it can actively avoid the vibration frequency of the compressor, avoid resonance between the refrigerant pipe 300 and the compressor, and improve the stability of the overall pipeline system.

[0051] Optionally, the rubber block for fixing the refrigerant pipe further includes: an air pressure regulating mechanism 400, a vibration sensor 500, a compressor frequency determination module 600 and a controller assembly 700. The air pressure regulating mechanism 400 is in communication with the airbag 205 and is used to control the air pressure in the airbag 205; the vibration sensor 500 is arranged on the refrigerant pipe 300 and / or the rubber block body 100 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 assembly 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 airbag 205 of the rubber block body 100 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. In this way, an airbag 205 is arranged in the rubber block body 100. By filling gas into the airbag 205, the tightness of the entire rubber block body 100 can be adjusted. The rubber block body 100 with different tightness has different fixing strengths on the refrigerant pipe 300, thereby changing the vibration frequency of the pipeline system. During the adjustment process, the vibration frequencies of the refrigerant pipe 300 and the compressor are determined in real time through the vibration sensor 500 and the compressor frequency determination module 600, and then the air pressure of the airbag 205 inside the rubber block body 100 is adjusted according to the frequency of the refrigerant pipe 300 and the compressor. The adjustment of pressure changes the tightness of the rubber block body 100, and then changes the vibration frequency of the rubber block body 100 and the refrigerant pipe 300 fixed by the rubber block body 100, so that the vibration frequency of the pipeline system avoids the frequency of the compressor, avoids resonance between the refrigerant pipe 300 and the compressor, and can effectively reduce the vibration amplitude of the refrigerant pipe 300, reduce noise, reduce the stress risk of the rubber block used to fix the refrigerant pipe, and improve the overall stability of the pipeline system. The air bag 205 inside the rubber block body 100 can absorb vibration waves, further consume vibration energy, reduce vibration amplitude, and reduce noise.

[0052] like Figure 6As 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 205 and is used to inflate the airbag 205; the deflation component 402 is connected to the airbag 205 and is used to release the gas in the airbag 205; the air pressure detection component 403 is arranged in the airbag 205 and is used to detect the air pressure in the airbag 205; 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 205 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 205 is changed by inflating air into the airbag 205 or releasing the gas in the airbag 205, thereby compressing or relaxing the rubber block body 100 to change the fixing force of the rubber block body 100 on the refrigerant pipe 300, thereby changing the overall vibration frequency of the pipeline system, so as to achieve the effect that the vibration frequency of the rubber block used to fix the refrigerant pipe can be adjusted, so that the vibration frequency of the pipeline system can avoid the vibration frequency of the compressor, thereby avoiding resonance between the rubber block used to fix the refrigerant pipe and the compressor. An air pressure detection component 403 is set in the airbag 205 to obtain the air pressure in the airbag 205 in real time, and feed it back to the air pressure control component 404, so that the air pressure in the airbag 205 can be adjusted more accurately, and the vibration frequency of the pipeline system can be stably controlled to change.

[0053] 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 205 via the small air compressor 406. In this way, the small air compressor 406 is used to compress the gas, so that the airbag 205 can be inflated efficiently and quickly to increase the air pressure in the airbag 205, and the gas stored in the gas tank 405 is used to inflate the airbag 205, so that the stability of the inflated gas can be maintained, and the problem of impurities entering and causing the airbag 205 to be contaminated and oxidized can be avoided.

[0054] 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.

[0055] It can be understood that the flame retardant gas can be carbon dioxide or the like.

[0056] 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.

[0057] Optionally, the airbag 205 is connected to the inflation component 401 through 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 205. In this way, by setting the one-way valve, when the airbag 205 is inflated, the reverse outflow of the air can be prevented, and the air pressure in the airbag 205 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 air. The overall structure is simple and has high stability.

[0058] Optionally, the vibration sensor 500 is provided with a plurality of sensing parts, and is respectively arranged on a plurality of refrigerant pipes 300 and the rubber block body 100. In this way, the vibrations on the refrigerant pipes 300 and the rubber block body 100 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.

[0059] Optionally, the rubber block body 100 is provided with a plurality of pipe fixing holes 103, and the pipe fixing holes 103 are used to fix the refrigerant pipe 300. In this way, the refrigerant pipe 300 can pass through the pipe fixing holes 103 on the rubber block body 100, so as to better fix the refrigerant pipe 300, and the refrigerant pipe 300 is fixed by a sleeve connection method, so that the connection between the rubber block body 100 and the refrigerant pipe 300 is more flexible and easy to adjust.

[0060] Optionally, obtaining the operating frequency of the compressor includes: connecting the compressor frequency determination module 600 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 rubber block used to fix the refrigerant pipe.

[0061] It can be understood that the operating frequency of the compressor can also be directly obtained by setting a sensor on the compressor.

[0062] Optionally, 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 400 to regulate the air pressure in the airbag 205 includes:

[0063] Calculate the difference between the operating frequency of the compressor and the vibration frequency of the pipeline system; 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, control the air pressure regulating mechanism 400 to maintain the current air pressure in the airbag 205; 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 the first threshold, control the air pressure regulating mechanism 400 to increase or decrease the air pressure in the airbag 205. 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 500, 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 205 in the rubber block body 100 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 high. At this time, by increasing or decreasing the air pressure of the airbag 205 in the rubber block body 100, the vibration frequency of the pipeline system can be changed, so that the vibration frequencies between the two are separated by a certain gap, 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.

[0064] 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 rubber block used to fix the refrigerant pipe.

[0065] 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 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 205 adjustment mechanism is controlled to adjust the air pressure of the airbag 205 of the rubber block body 100, so that the vibration frequency of the pipeline system changes, better avoid resonance between the compressor and the pipeline system, eliminate the stress risk of the pipeline system, and improve the stability of the pipeline system.

[0066] 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.

[0067] Optionally, 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 value, the air pressure regulating mechanism 400 is controlled to increase or decrease the air pressure in the airbag 205, including: obtaining the current air pressure of the airbag 205 in the rubber block body 100; when it is determined that the current air pressure of the airbag 205 in the rubber block body 100 is in a first preset area, the air pressure regulating mechanism 400 is controlled to increase the air pressure in the airbag 205; when it is determined that the current air pressure of the airbag 205 is in a second preset area, the air pressure regulating mechanism 400 is used to reduce the air pressure in the airbag 205. In this way, when it is necessary to adjust the air pressure of the airbag 205 in the rubber block main body 100, the current air pressure of the airbag 205 can be obtained, and according to the range of the air pressure in the airbag 205, the airbag 205 adjustment mechanism is controlled to increase or decrease the air pressure of the airbag 205. When the current air pressure of the airbag 205 is high, the air pressure of the airbag 205 is reduced, and when the current air pressure of the airbag 205 is low, the air pressure of the airbag 205 is increased. The air pressure of the airbag 205 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 205 of the rubber block main body 100 from exceeding its adjustable range when adjusting the air pressure, causing damage to the rubber block main body 100, or adjustment failure.

[0068] Optionally, the adjustable range of the air pressure of the airbag 205 in the rubber block body 100 is determined, the first preset area is the first half of the adjustable range of the air pressure of the airbag 205 in the rubber block body 100, and the second preset area is the second half of the adjustable range of the air pressure of the airbag 205 in the rubber block body 100, wherein the range of the first preset area is greater 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 205, so when the current air pressure is in the first preset area, it means that the air pressure of the airbag 205 has room to be increased, so the air pressure of the airbag 205 is controlled to increase, and vice versa, when it is in the second preset area, the air pressure of the airbag 205 can be controlled to decrease, wherein the range of the first preset area is greater than the second preset area, which can increase the probability of increasing the air pressure of the airbag 205 in the adjustment stage, and give priority to increasing the air pressure of the airbag 205, which can improve the fixing effect of the refrigerant pipe 300.

[0069] Optionally, the adjustable air pressure range of the airbag 205 is determined, and the first preset area is the first four-fifths of the adjustable air pressure range of the airbag 205, and the second preset area is the last one-fifth of the adjustable air pressure range of the airbag 205. In this way, by determining the adjustable air pressure range of the airbag 205, the adjustment strategy for the airbag 205 is controlled. When the current air pressure of the airbag 205 is in the first four-fifths of the adjustable air pressure range, it means that the air pressure of the airbag 205 still has room for upward adjustment. Therefore, the air pressure of the airbag 205 is increased first, which can change the vibration frequency of the pipeline system and increase 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 205 can further squeeze the rubber block body 100, increase the fixing force on the refrigerant pipe 300, and reduce The vibration amplitude of the refrigerant pipe 300 is better for shock absorption and noise reduction. When the current air pressure of the airbag 205 is in the last one-fifth of its adjustable air pressure range, it means that the air pressure of the airbag 205 is about to reach the upper limit. Continuing to increase the pressure at this time may easily cause damage to the rubber block body 100, or the adjustment demand cannot be met after the air pressure upper limit of the airbag 205 is reached. Therefore, it is preferred to reduce the air pressure of the airbag 205 to make its adjustable range larger, which can better ensure that the vibration frequency of the pipeline system and the vibration frequency of the compressor are kept a certain distance away to avoid resonance.

[0070] 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 300 and the rubber block body 100.
