[0001] This application relates to the technical field of air conditioner vibration reduction, for example, to a method and device for compressor vibration reduction, a compressor, and an air conditioning system. Background Art

[0002] During the operation of an air conditioner compressor, vibrations of a certain frequency will be generated. The vibrations are transmitted from the base and feet of the compressor to the air conditioner chassis, thereby causing vibrations and radiated noise problems of the entire outdoor unit of the air conditioner.

[0003] To reduce the vibrations generated during the operation of the compressor, related technologies disclose a control method, including: controlling the operation of the compressor; controlling the air pump to fill air into the air-filled foot pads; obtaining the vibration parameters or noise value of the compressor and the air pressure in the air-filled foot pads to obtain the air pressure P in the air-filled foot pads when the vibration parameters are minimized; introducing the air pressure P into the static stiffness fitting curve to obtain the foot pad static stiffness K corresponding to P; wherein, the static stiffness fitting curve is a fitting of the air pressure in the air-filled foot pads and the actual foot pad static stiffness used; and matching the actual foot pads used according to the foot pad static stiffness K.

[0004] In the process of implementing the embodiments of the present disclosure, it is found that at least the following problems exist in related technologies:

[0005] Although related technologies can obtain the air pressure in the air-filled foot pads to obtain the static stiffness of the foot pads, and then match the actual foot pads used, in actual applications, the air pressure in the foot pads is fixed and cannot be suitable for all stages of the compressor operation, thereby resulting in a general vibration reduction effect.

[0006] It should be noted that the information disclosed in the above background art section is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute the prior art known to those of ordinary skill in the art. Summary of the Invention

[0007] To provide a basic understanding of some aspects of the disclosed embodiments, a simple summary is given below. The summary is not a general review, nor is it intended to identify key / important elements or delineate the scope of protection of these embodiments, but rather serves as a preamble to the following detailed description.

[0008] The embodiments of the present disclosure provide a method and device for compressor vibration reduction, a compressor, and an air conditioning system to improve the vibration reduction effect on the compressor.

[0009] In some embodiments, the method for damping vibration of a compressor includes: obtaining the operating stage of the compressor; adjusting the air pressure of the pneumatic damping structure according to the operating stage. When the compressor is in different operating stages, the vibrations generated are different. Therefore, by obtaining the operating stage of the compressor and then adjusting the air pressure of the pneumatic damping structure based on the operating stage, that is, adjusting the restraining force of the pneumatic damping structure on the compressor. In this way, the damping effect of the pneumatic damping structure on the compressor can be dynamically adjusted as the operating stage of the compressor changes, and thus it can be achieved that throughout the entire operation process of the compressor, an appropriate damping effect on the compressor can be achieved through the pneumatic damping structure.

[0010] In some embodiments, adjusting the air pressure inside the pneumatic damping structure according to the operating stage includes: when the operating stage is the pre-start stage, controlling the pneumatic damping structure to inflate to a first pressure; controlling the pneumatic damping structure to maintain the first pressure during the pre-start stage. In this way, when the compressor is in the pre-start stage, that is, when the compressor jitters severely, controlling the air pump to inflate the pneumatic damping structure to a relatively large first pressure, so as to provide sufficient restraining force for the compressor.

[0011] In some embodiments, the first pressure is determined by the following method: obtaining the pressure resistance level of the pneumatic damping structure, the mass of the compressor body, and the vibration amplitude when the compressor pre-starts; determining the first pressure according to the pressure resistance level, the mass of the compressor body, and the vibration amplitude. In this way, during the pre-start stage of the compressor, considering the pressure resistance level that can affect the restraining force of the compressor, the mass of the compressor body that can affect the vibration of the compressor, and the actual vibration amplitude of the compressor, the first pressure is determined, so that the air pressure inside the pneumatic damping structure matches the vibration of the compressor, and thus sufficient restraining force is provided for the compressor, improving the damping effect on the compressor.

[0012] In some embodiments, controlling the pneumatic damping structure to inflate to the first pressure includes: determining a first gas adjustment rate according to the gas flow rate of inflation and the working pressure of the pneumatic damping structure; controlling the pneumatic damping structure to inflate to the first pressure at the first gas adjustment rate. In this way, considering the gas volume of inflation by the air pump and the working pressure of the pneumatic damping structure, the gas adjustment rate is determined, so that the air pressure inside the damping foot pad can quickly reach the first pressure, and thus quickly respond to the vibration of the compressor to improve the damping effect.

[0013] In some embodiments, according to the operating stage, the air pressure inside the pneumatic damping structure is adjusted, further including: when the operating stage is the starting stage, controlling the pneumatic damping structure to deflate to a second pressure; controlling the pneumatic damping structure to maintain the second pressure during the starting stage. In this way, when the compressor is in the starting stage, that is, when the compressor does not require excessive restraint force, controlling the pneumatic damping structure to deflate to the second pressure can not only provide an appropriate restraint force for the compressor, reduce the vibration of the compressor, but also avoid the problem that the damping foot pads are prone to aging due to long-term high pressure.

[0014] In some embodiments, according to the operating stage, the air pressure of the pneumatic damping structure is adjusted, including: when the operating stage is the stable operation stage, determining a third pressure according to the vibration frequency and vibration amplitude of the compressor body; controlling the air pressure of the pneumatic damping structure to be adjusted to the third pressure. In this way, when the compressor is in the stable operation stage, considering that the vibration frequency and vibration amplitude of the compressor will change with the operating state of the air-conditioning system, and then controlling the air pressure of the pneumatic damping structure to be adjusted to the third pressure based on the vibration frequency and vibration amplitude of the compressor, so as to change the stiffness and damping of the damping foot pads, and maximize the absorption and isolation of the vibration transmitted from the compressor base to the air-conditioning outdoor unit chassis.

[0015] In some embodiments, according to the operating stage, the air pressure of the pneumatic damping structure is adjusted, including: when the operating stage is the shutdown stage, controlling the air pressure of the pneumatic damping structure to be adjusted to a fourth pressure. In this way, when the compressor is in the shutdown stage, controlling the air pressure of the pneumatic damping structure to be adjusted to the fourth pressure can avoid the problem that the damping foot pads are prone to aging due to long-term inflation.

[0016] In some embodiments, the device for damping the compressor includes: a processor and a memory storing program instructions, and the processor is configured to execute the aforementioned method for damping the compressor when running the program instructions.

[0017] In some embodiments, the compressor includes: a compressor body; the aforementioned device for damping the compressor is installed on the compressor body.

[0018] In some embodiments, the air-conditioning system includes the aforementioned compressor.

[0019] The method and device for damping the compressor, the compressor, and the air-conditioning system provided by the embodiments of the present disclosure can achieve the following technical effects:

[0020] When the compressor is in different operating stages, the vibrations it generates are different. Therefore, the operating stage of the compressor is obtained, and then the air pressure of the pneumatic damping structure is adjusted based on the operating stage, that is, the binding force of the damping structure on the compressor is adjusted. In this way, the damping effect of the damping structure on the compressor can be dynamically adjusted as the operating stage of the compressor changes, and thus it can be achieved that throughout the entire operating process of the compressor, an appropriate damping effect on the compressor can be achieved through the damping structure.

[0037] In order to be able to understand the features and technical content of the embodiments of the present disclosure in more detail, the implementation of the embodiments of the present disclosure will be described in detail below with reference to the drawings.

[0039] Unless otherwise specified, the term "plurality" means two or more.

[0040] In the embodiments of the present disclosure, the character " / " indicates that the objects before and after are in an "or" relationship. For example, A / B means: A or B.

[0041] The term "and / or" is an associative relationship describing an object and indicates that three relationships can exist. For example, A and / or B means: A or B, or, A and B these three relationships.

[0042] The term "corresponding" may refer to an associative relationship or a binding relationship. A corresponding to B means that there is an associative relationship or a binding relationship between A and B.

[0043] Combined with Figure 1 and Figure 2As shown in the figure, in order to reduce the vibration generated by the operation of the compressor 10 from being transmitted to the indoor unit and affecting the user experience, an inflatable vibration damping structure 20 (hereinafter referred to as "vibration damping structure 20") is provided between the base of the compressor 10 and the chassis of the outdoor unit to reduce the vibration transmission and the internal resonance of the outdoor unit. The inflatable vibration damping structure 20 includes: an air pump 22 and an inflatable vibration damping foot pad 21. The air pump 22 is communicatively connected to the processor to control the air pump 22 to turn on or off. The air outlet end of the air pump 22 is communicated with the vibration damping foot pad 21. When the air pump 22 is controlled to turn on, the air pump 22 operates and inflates the vibration damping foot pad 21 to increase the internal air pressure of the vibration damping foot pad 21. The vibration damping foot pad 21 is provided with a pressure relief valve 23, and the processor is also communicatively connected to the pressure relief valve 23 to control the pressure relief valve 23 to turn on or off. When the pressure relief valve 23 is controlled to turn on, the air in the vibration damping foot pad 21 flows out through the pressure relief valve 23, so as to achieve the purpose of relieving the pressure of the vibration damping foot pad 21. Thus, by controlling the on-off of the air pump 22 and the pressure relief valve 23, the air pressure in the vibration damping foot pad 21 can be adjusted, and further the binding force of the vibration damping foot pad 21 on the compressor 10 can be adjusted.

[0044] Optionally, vibration damping structures 20 are respectively arranged at the four corners of the base of the compressor 10 to provide a uniform and stable binding force on the compressor 10, thereby ensuring the vibration damping effect of the vibration damping structure 20 on the compressor 10.

[0045] Based on the above compressor, combined with Figure 3 As shown in the figure, an embodiment of the present disclosure provides a method for damping a compressor, including:

[0046] S101, the processor obtains the operation stage of the compressor.

[0047] S102, the processor adjusts the air pressure of the inflatable vibration damping structure according to the operation stage.

[0048] The processor is communicatively connected to the compressor, and thus can obtain the operation stage of the compressor. Optionally, the operation stages of the compressor are: pre-start stage, start stage, stable operation stage, and shutdown stage. According to the current operation stage of the compressor, by controlling the air pump to inflate the vibration damping foot pad of the vibration damping structure, or by controlling the pressure relief valve to deflate the vibration damping foot pad, the internal air pressure of the vibration damping foot pad is adjusted. In this way, the air pressure of the vibration damping foot pad can be matched with the operation stage of the compressor.

[0049] In the disclosed embodiment, when the compressor is in different operating stages, the vibrations it generates are different. Therefore, the operating stage of the compressor is obtained, and then the air pressure of the inflatable vibration reduction structure is adjusted based on the operating stage, that is, the restraining force of the vibration reduction structure on the compressor is adjusted. In this way, the vibration reduction effect of the vibration reduction structure on the compressor can be dynamically adjusted as the operating stage of the compressor changes, and then it can be achieved that during the entire operation process of the compressor, the vibration reduction structure can achieve a suitable vibration reduction effect on the compressor.

[0050] Combination Figure 4 As shown, the embodiment of the present disclosure provides another method for reducing vibration of a compressor, comprising:

[0051] S101: The processor obtains the operating stage of the compressor.

[0052] S112: When the operation phase is a pre-start phase, the processor controls the inflatable vibration reduction structure to be inflated to a first pressure.

[0053] S122, the processor controls the inflatable vibration reduction structure to maintain a first pressure during the pre-startup phase.

[0054] When the air conditioning system is initially turned on, the compressor needs to be pre-started when it changes from an unstarted state to a started state. When the compressor is in the pre-start stage, the compressor itself is affected by the internal motor torque, the compressor's own air intake, and the compressor's own exhaust, which will produce relatively violent vibrations. Therefore, the vibration-damping foot pads of the vibration-damping structure need to be filled with enough gas to provide sufficient restraint for the compressor, thereby reducing the amplitude of the compressor itself, thereby protecting the compressor piping and other structures.

[0055] Therefore, when the compressor is in the pre-start stage, the vibration reduction structure is controlled to be inflated to the first pressure. Specifically, after determining that the compressor is in the pre-start stage, the processor controls the air pump to start. The air pump fills the vibration reduction pad with gas so that the gas pressure in the vibration reduction pad reaches the first pressure. The first pressure is a relatively large pressure, so that sufficient restraint can be provided when the compressor shakes more violently.

[0056] A pressure sensor is provided in the vibration-damping pad, and the pressure sensor is communicatively connected to the processor so as to provide real-time feedback of the changes in the gas pressure in the vibration-damping pad to the processor. When the gas pressure in the vibration-damping pad reaches a first pressure, the processor controls the air pump to turn off. Optionally, if after the air pump is controlled to be turned off, the pressure change feedback by the pressure sensor indicates that the gas pressure in the vibration-damping pad decreases, the air pump is controlled to turn on. In this way, when the compressor is in the pre-startup stage, the gas pressure level in the vibration-damping pad is always controlled to be maintained at the first pressure.

[0057] In this way, when the compressor is in the pre-startup stage, that is, when the compressor vibrates violently, the inflation pump is controlled to inflate the vibration damping structure to a relatively large first pressure, so as to provide sufficient restraint force for the compressor.

[0058] Optionally, the first pressure ranges from 1.0 Mpa to 1.2 Mpa.

[0059] Optionally, the first pressure is determined by the following method:

[0060] The processor obtains the pressure resistance level of the inflatable vibration damping structure, the mass of the compressor body, and the vibration amplitude during the pre-startup of the compressor.

[0061] The processor determines the first pressure according to the pressure resistance level, the mass of the compressor body, and the vibration amplitude.

[0062] Before the vibration damping structure is put into use, the pressure resistance level of the vibration damping structure and the mass of the compressor body are pre-stored in the memory. The processor is also communicatively connected to an acceleration sensor, which is used to detect the vibration amplitude of the compressor. The higher the pressure resistance level of the vibration damping structure, the greater the inflatable degree of the vibration damping structure, and the greater the restraint force that can be provided for the compressor. The greater the mass of the compressor body, the greater the vibration amplitude of the compressor. Therefore, when the compressor starts and is in the pre-startup stage, based on the vibration amplitude of the compressor feedback by the acceleration sensor, and retrieving the pre-stored pressure resistance level of the vibration damping structure and the mass of the compressor body, the first pressure is determined.

[0063] In this way, in the pre-startup stage of the compressor, the first pressure is determined by comprehensively considering the pressure resistance level that can affect the restraint force of the compressor, the mass of the compressor body that can affect the vibration of the compressor, and the actual vibration amplitude of the compressor, so that the air pressure in the vibration damping structure matches the vibration of the compressor, thereby providing sufficient restraint force for the compressor and improving the vibration damping effect on the compressor.

[0064] Optionally, the pressure resistance level, the mass of the compressor body, and the vibration amplitude are positively correlated with the first pressure. Optionally, the pressure resistance level, the mass of the compressor body, and the vibration amplitude are divided into multiple interval levels. The larger the upper limit value of the interval level, the greater the corresponding first pressure. Specifically, the corresponding relationship between the interval level and the first pressure is shown in Table 1:

[0065] Table 1 Corresponding relationship between interval level and first pressure

[0066] Withstand voltage level Mass (m) of the compressor body Vibration amplitude (A) <![CDATA[First pressure (P1)]]> First stage <![CDATA[(0, m1]]]> <![CDATA[(0, A1]]]> <![CDATA[P 11 > Second stage <![CDATA[(m1, m2]]]> <![CDATA[(A1, A2]]]> <![CDATA[P 12 > Third stage <![CDATA[(m2, +∞)]]> <![CDATA[(A2, +∞)]]> <![CDATA[P 13 >

[0067] In Table 1, m1 is the first mass threshold, m2 is the second mass threshold, m1 < m2; A1 is the first amplitude threshold, A2 is the second amplitude threshold, A1 < A2; P 11 <P 12<P 13 。

[0068] It should be noted that those skilled in the art can divide more interval levels, and this embodiment does not make specific limitations thereto.

[0069] Optionally, the processor controls the damping structure to inflate to the first pressure at the first gas regulation rate. Optionally, the value of the first gas regulation rate is from 0.02 Mpa / s to 0.03 Mpa / s.

[0070] Optionally, in S112, the processor controls the inflatable damping structure to inflate to the first pressure, including:

[0071] The processor determines the first gas regulation rate according to the gas flow rate of inflation and the working pressure of the inflatable damping structure.

[0072] The processor controls the inflatable damping structure to inflate to the first pressure at the first gas regulation rate.

[0073] The flow sensor is arranged at the outlet of the inflator and is used to detect the gas flow rate of inflation. The processor is also communicatively connected to the flow sensor to receive the gas flow rate feedback by the flow sensor in real time. During the process of controlling the damping structure to inflate to the first pressure, the processor determines the first gas regulation rate according to the gas flow rate of inflation and the working pressure of the damping structure. Then it controls the damping structure to inflate to the first pressure at the first gas regulation rate.

[0074] Optionally, the processor makes the inflation rate reach the first gas regulation rate by controlling the rotation speed of the inflator.

[0075] In this way, the gas regulation rate is determined by comprehensively considering the gas volume of inflation by the inflator and the working pressure of the damping structure, so that the air pressure in the damping foot pad can quickly reach the first pressure, and then quickly respond to the vibration of the compressor, so as to improve the damping effect.

[0076] Optionally, the greater the gas flow rate of inflation, the more gas enters the damping foot pad per unit time. The greater the working pressure of the damping structure, it indicates that the weight of the compressor is greater, then the vibration amplitude of the compressor is also greater, and further, the air pressure in the damping foot pad needs to reach the first pressure more quickly, then the first gas regulation rate required is greater. Therefore, the smaller the gas flow rate of inflation and the greater the working pressure of the damping structure, the greater the first gas regulation rate.

[0077] In this way, the first gas regulation rate is determined by comprehensively considering the gas flow rate of inflation by the inflator and the working pressure of the damping structure, so that the air pressure in the damping foot pad can quickly reach the first pressure, and then quickly provide sufficient restraint force for the compressor, thereby improving the damping effect on the compressor.

[0078] Combined with Figure 5As shown in the figure, an embodiment of the present disclosure provides another method for compressor vibration reduction, including:

[0079] S101, the processor obtains the operating stage of the compressor.

[0080] S132, when the operating stage is the starting stage, the processor controls the pneumatic vibration reduction structure to deflate to the second pressure.

[0081] S142, the processor controls the pneumatic vibration reduction structure to maintain the second pressure during the starting stage.

[0082] After the air conditioner is turned on and before it operates stably, it is in the starting stage. During this stage, the rotational speed of the compressor continuously increases and stabilizes at a certain specific rotational frequency. At this time, the rotational frequency of the compressor is relatively low, aiming to balance the load of the air conditioning system, so that the compressor can fully return oil and lubricate. At this time, the load of the air conditioning system is relatively low, the rotational frequency of the compressor is relatively low, the amplitude of the compressor itself is relatively small, and the noise is relatively low. The oil temperature of the compressor is not high at this stage, the lubrication system has not reached the best state, and the refrigerant system of the whole machine has not completed a complete cycle. Therefore, the pressure relief valve is controlled to open, and then the vibration reduction structure is controlled to deflate, so that the internal air pressure is reduced to the second pressure. In this way, the vibration reduction foot pads can provide sufficient constraint stiffness for the compressor to ensure that the compressor reaches a stable state.

[0083] After the air pressure inside the vibration reduction foot pads reaches the second pressure, the pressure relief valve is controlled to close. If after the pressure relief valve is controlled to close, the pressure change feedback by the pressure sensor indicates that the gas pressure inside the vibration reduction foot pads decreases, then the air inflation pump is controlled to start. In this way, when the compressor is in the starting stage, the gas pressure level inside the vibration reduction foot pads is always maintained at the second pressure.

[0084] In this way, when the compressor is in the starting stage, that is, when the compressor does not require too large a restraining force, the vibration reduction structure is controlled to deflate to the second pressure, which can not only provide appropriate restraint force for the compressor, reduce the vibration of the compressor, but also avoid the problem that the vibration reduction foot pads are prone to aging due to long-term high pressure.

[0085] Optionally, the second pressure is less than the first pressure. Optionally, the second pressure is 80% of the first pressure.

[0086] Optionally, the second pressure ranges from 0.8 Mpa to 1.0 Mpa.

[0087] Optionally, the pneumatic vibration reduction structure is controlled to deflate to the second pressure at the second gas regulation rate. Optionally, the second gas regulation rate is less than the first gas regulation rate. Optionally, the second gas regulation rate ranges from 0.01 Mpa / s to 0.015 Mpa / s.

[0088] Optionally, in S132, the processor controls the pneumatic damping structure to deflate to a second pressure, including:

[0089] The processor controls the pneumatic damping structure to deflate to the second pressure at a second gas regulation rate, where the second gas regulation rate is less than the first gas regulation rate.

[0090] During the process of the processor controlling the damping structure to deflate to the second pressure, the processor controls the damping structure to deflate at the second gas regulation rate. The second gas regulation rate is less than the first gas regulation rate, that is, the damping structure is controlled to deflate slowly.

[0091] In this way, by controlling the damping structure to deflate slowly at a smaller second gas regulation rate, stable deflation of the damping structure can be achieved, and then a smooth transition of the constraint force of the damping structure on the compressor can be realized, thereby ensuring the damping effect of the damping structure on the compressor.

[0092] Combined with Figure 6 As shown, an embodiment of the present disclosure provides another method for damping a compressor, including:

[0093] S101, the processor obtains the operating stage of the compressor.

[0094] S152, when the operating stage is the stable operating stage, the processor determines a third pressure according to the vibration frequency and vibration amplitude of the compressor body.

[0095] S162, the processor controls the air pressure of the pneumatic damping structure to be adjusted to the third pressure.

[0096] After the compressor is turned on for a period of time, it enters the stable operating stage. As the operating frequency of the air-conditioning system is adjusted, the vibration frequency and vibration amplitude of the compressor will also change. Therefore, the processor obtains the vibration frequency and vibration amplitude of the compressor body. The vibration amplitude and vibration frequency can reflect the vibration degree of the compressor at this time, and then the third pressure can be determined based on the vibration frequency and vibration amplitude. Then, the inflation pump is controlled to be turned on to inflate the damping footpad, or the pressure relief valve is controlled to be turned on to deflate the damping footpad, so as to adjust the air pressure in the damping footpad to the third pressure matching the vibration amplitude and vibration frequency of the compressor.

[0097] In this way, when the compressor is in the stable operating stage, considering that the vibration frequency and vibration amplitude of the compressor will change with the operating state of the air-conditioning system, and then controlling the air pressure of the damping structure to be adjusted to the third pressure based on the vibration frequency and vibration amplitude of the compressor, so as to change the stiffness and damping of the damping footpad, so as to maximize the absorption and isolation of the vibration transmitted from the compressor base to the air-conditioning outdoor unit chassis.

[0098] Optionally, the vibration frequency and the vibration amplitude are positively correlated with the third pressure. This is because the greater the vibration frequency and / or the greater the vibration amplitude, the greater the degree of vibration of the compressor, the greater the binding force required by the compressor, and thus the greater the third pressure of the gas filled in the vibration damping foot pad. Optionally, the vibration frequency and the vibration amplitude are divided into multiple intervals, and the greater the upper limit value of the interval, the greater the corresponding third pressure. Specifically, for the correspondence between the intervals of the vibration frequency and the vibration amplitude and the third pressure, see Table 2:

[0099] Table 2 Correspondence between the interval levels of the vibration frequency and the vibration amplitude and the third pressure

[0100] Vibration frequency (f) Vibration amplitude (A) <![CDATA[Third pressure (P3)]]> <![CDATA[(0, f1]]]> <![CDATA[(0, A1]]]> <![CDATA[P 31 > <![CDATA[(f1, f2]]]> <![CDATA[(A1, A2]]]> <![CDATA[P 32 > <![CDATA[(f2, +∞)]]> <![CDATA[(A2, +∞)]]> <![CDATA[P 33 >

[0101] In Table 2, f1 is the first frequency threshold, f2 is the second frequency threshold, and f1 < f2; A1 is the first amplitude threshold, A2 is the second amplitude threshold, and A1 < A2; P 31 <P 32 <P 33 。

[0102] It should be noted that those skilled in the art can divide more interval levels for the vibration frequency and the vibration amplitude, and this embodiment does not make specific limitations on it.

[0103] Optionally, the processor controls the pneumatic damping structure to adjust the air pressure to the third pressure at the third gas adjustment rate. Optionally, the third gas adjustment rate is less than the first gas adjustment rate. Optionally, the third gas adjustment rate ranges from 0.01 Mpa / s to 0.015 Mpa / s.

[0104] Optionally, the processor controls the air pressure of the pneumatic damping structure to be adjusted to the third pressure, including:

[0105] The processor determines the third gas adjustment rate according to the change degree of the vibration frequency and the vibration amplitude of the compressor body.

[0106] The processor controls the pneumatic damping structure to adjust the air pressure to the third pressure at the third gas adjustment rate.

[0107] The faster the change of the vibration frequency of the compressor body and / or the faster the change of the vibration amplitude, the faster the air pressure in the vibration foot pad is required to change, so that the binding force of the vibration damping foot pad can be quickly matched to the operating state of the compressor. Therefore, the processor determines the third gas adjustment rate according to the vibration frequency and the vibration amplitude of the compressor body. Then, it controls the damping structure to increase / decrease the air pressure to the third pressure at the third gas adjustment rate. Specifically, the faster the change of the vibration frequency and / or the faster the change of the vibration amplitude, the greater the third gas adjustment rate.

[0108] Combined with Figure 7As shown in the figure, an embodiment of the present disclosure provides another method for compressor vibration reduction, including:

[0109] S101, a processor obtains the operating stage of the compressor.

[0110] S172, when the operating stage is the shutdown stage, the processor controls the air pressure of the inflatable vibration reduction structure to be adjusted to the fourth pressure.

[0111] When the air-conditioning system enters the shutdown unloading stage, the compressor shuts down. When the operating stage of the compressor is the shutdown stage, the pressure relief valve is controlled to open, and then the air pressure of the vibration reduction foot pad is controlled to drop to the fourth pressure. Wherein, the fourth pressure is less than the second pressure and less than the third pressure. Optionally, the fourth pressure takes the value of standard atmospheric pressure.

[0112] In this way, when the compressor is in the shutdown stage, the air pressure of the vibration reduction structure is controlled to be adjusted to the fourth pressure, avoiding the problem that the vibration reduction foot pad is prone to aging when it is in the inflated state for a long time.

[0113] Optionally, the processor controls the inflatable vibration reduction structure to adjust the air pressure to the fourth pressure at the fourth gas adjustment rate.

[0114] Optionally, the fourth gas adjustment rate is greater than the second gas adjustment rate and greater than the third gas adjustment rate, so as to quickly release the pressure of the vibration reduction foot pad.

[0115] Optionally, the fourth gas adjustment rate takes the value of 0.02 Mpa / s.

[0116] Optionally, the processor controls the pressure relief valve to open completely to release the air of the vibration reduction foot pad at the fastest speed.

[0117] Combined with Figure 8 As shown in the figure, an embodiment of the present disclosure provides a device 80 for compressor vibration reduction, including: an acquisition module 81 and a control module 82. The acquisition module 81 is configured to obtain the operating stage of the compressor. The control module 82 is configured to adjust the air pressure of the inflatable vibration reduction structure according to the operating stage.

[0118] When using the device 80 for compressor vibration reduction provided by the embodiment of the present disclosure, the vibrations generated are different when the compressor is in different operating stages. Therefore, the operating stage of the compressor is obtained, and then the air pressure of the inflatable vibration reduction structure is adjusted based on the operating stage, that is, the binding force of the vibration reduction structure on the compressor is adjusted. In this way, the vibration reduction effect of the vibration reduction structure on the compressor can be dynamically adjusted with the change of the operating stage of the compressor, and thus, during the entire operation process of the compressor, an appropriate vibration reduction effect on the compressor can be achieved through the vibration reduction structure.
