As shown in fig. 1, an embodiment of the present disclosure provides a compressor damping method for a variable frequency air conditioner configured with a compressor, a pipe group connected to the compressor, a supporting device installed at the bottom of the compressor, and a clamping device clamped to the outer wall of the supporting device. The method comprises the following steps:
s01, acquiring an information table, wherein the information table stores the test frequency of the compressor and the clamping force of a clamping device associated with the test frequency, and the test frequency and the clamping force are determined by the stress of the pipeline group.
S02, when the compressor is in an operation stage, the target frequency of the compressor is obtained.
S03, if the target frequency of the compressor is matched with the test frequency, matching the target clamping force corresponding to the target frequency from the information table.
S04, controlling the clamping device to perform clamping operation on the supporting device with target clamping force so as to reduce vibration of the compressor.
By adopting the compressor damping method for the variable frequency air conditioner, when the compressor is in the operation stage, the target frequency of the compressor is obtained, if the frequency is matched with the test frequency stored in the information table, damping operation is required to be carried out on the compressor under the target frequency, at the moment, the target clamping force corresponding to the target frequency is matched from the information table, and the clamping device is controlled to carry out clamping operation on the supporting device with the target clamping force, so that damping is realized. When the vibration reduction operation is needed to be carried out on the compressor, the method effectively solves the problem of exceeding the stress of the outdoor unit pipeline group by matching the target clamping force corresponding to the target frequency from the information table and carrying out the clamping operation by the target clamping force and reducing the vibration of the compressor by enhancing the rigidity of the supporting device.
The pipeline group can be an exhaust pipe or an air return pipe.
Alternatively, the support means may have elastically deformable support members, for example resilient footpads. The clamping device can be a clamping seat or a manipulator. The structure of the supporting device and the structure of the clamping device are not particularly limited in the embodiments of the present disclosure. As an example, referring to fig. 7, the supporting device 10 is a cylindrical elastic foot pad, which is mounted at the bottom of the compressor, and the clamping device 20 is a clamping seat, which is sleeved in the circumferential direction of the elastic foot pad.
Alternatively, the target frequency of the compressor is matched with the test frequency, and the target frequency may be equal to the test frequency.
Optionally, as shown in connection with fig. 2, the test frequency of the compressor and the clamping force of the clamping device associated with the test frequency are determined in the following manner:
s11, when the compressor is in a testing stage, the current stress of the pipeline group is obtained.
And S12, if the current stress is larger than the stress threshold value, determining the frequency of the compressor corresponding to the current stress as the test frequency.
And S13, controlling the clamping device to increase the clamping force on the supporting device so that the adjusted current stress is smaller than or equal to the stress threshold value.
And S14, determining the clamping force corresponding to the adjusted current stress as the clamping force related to the test frequency.
Therefore, when the compressor is in the test stage, if the current stress of the pipeline group is larger than the stress threshold value, the stress of the pipeline group is indicated to be out of standard, at the moment, the frequency of the compressor corresponding to the current stress is determined to be the test frequency, the clamping force corresponding to the adjusted current stress is determined to be the clamping force related to the test frequency, and the test frequency of the compressor corresponding to the out-of-standard stress of the pipeline group and the clamping force of the clamping device corresponding to the test frequency can be effectively determined by the method, so that more accurate reference data is provided for damping operation of the compressor in the operation stage, and vibration of the pipeline group is further effectively reduced.
As one example, the pipe group is an exhaust pipe having a plurality of pipe bodies and welded portions for communication of the adjacent pipe bodies. And a pressure sensor for detecting stress is arranged on part or all of the pipe body and the welding part. The pipe body is a pipe body corresponding to the exhaust pipe. By arranging the pressure sensors, the detection accuracy of the stress of the pipeline group can be improved.
As shown in fig. 3, the embodiment of the present disclosure further provides a compressor damping method for a variable frequency air conditioner configured with a compressor, a pipe group connected to the compressor, a supporting device installed at the bottom of the compressor, and a clamping device clamped to the outer wall of the supporting device. The method comprises the following steps:
s21, acquiring an information table, wherein the information table stores the test frequency of the compressor and the clamping force of a clamping device associated with the test frequency, and the test frequency and the clamping force are determined by the stress of the pipeline group.
S22, when the compressor is in an operation stage, the target frequency of the compressor is obtained.
S23, if the target frequency of the compressor is matched with the test frequency, the target clamping force corresponding to the target frequency is matched from the information table.
S24, controlling the clamping device to perform clamping operation on the supporting device with the target clamping force so as to reduce vibration of the compressor.
S25, acquiring new target frequency again.
S26, if the new target frequency is not matched with the target frequency, controlling the clamping device to reduce the clamping force on the supporting device.
By adopting the compressor damping method for the variable frequency air conditioner, since the stress value of the pipeline group is in a dynamic change state, after the stress of the pipeline group exceeds the standard for the first time, the clamping operation is performed on the supporting device by the clamping device, so that the rigidity of the supporting device can be improved, the stress value of the pipeline group in the subsequent operation stage of the compressor can be influenced, for example, the stress of the pipeline group can be reduced, and the condition that the stress exceeds the standard can be caused to a certain subsequent frequency value, therefore, after the clamping operation is performed on the supporting device by the clamping device with the target clamping force, a new target frequency needs to be acquired again, and when the new target frequency does not match with the target frequency, the clamping force on the supporting device is controlled to be reduced, so that the influence on the stress of the pipeline group in the subsequent operation stage of the compressor is avoided.
Alternatively, the new target frequency does not match the target frequency, which may be that the new target frequency is greater than the target frequency, or that the new target frequency is less than the target frequency. As one example, a determination is made as to whether the new target frequency is equal to the target frequency, and if not, a determination is made that the new target frequency does not match the target frequency.
As shown in fig. 4, the embodiment of the present disclosure further provides a compressor damping method for a variable frequency air conditioner configured with a compressor, a pipe group connected to the compressor, a supporting device installed at the bottom of the compressor, and a clamping device clamped to the outer wall of the supporting device. The method comprises the following steps:
s31, acquiring an information table, wherein the information table stores the test frequency of the compressor and the clamping force of a clamping device associated with the test frequency, and the test frequency and the clamping force are determined by the stress of the pipeline group.
S32, acquiring the resonance frequency of the compressor related to the resonance state of the pipeline group.
S33, when the compressor is in the operation stage, the target frequency of the compressor is obtained.
S34, judging whether the target frequency of the compressor is matched with the resonance frequency, if so, executing S35, and if not, executing S36.
S35, controlling the compressor to execute frequency hopping operation.
S36, judging whether the target frequency of the compressor is matched with the test frequency, if so, executing S37.
S37, matching the target clamping force corresponding to the target frequency from the information table.
S38, controlling the clamping device to perform clamping operation on the supporting device with the target clamping force so as to reduce vibration of the compressor.
By adopting the compressor damping method for the variable frequency air conditioner, which is provided by the embodiment of the disclosure, the pipeline group may be in a resonance state to cause the stress exceeding, and at this time, the problem of the stress exceeding of the pipeline group does not need to be solved, so after the target frequency of the compressor is obtained, whether the target frequency of the compressor is matched with the resonance frequency is firstly judged, if so, the compressor is controlled to execute the frequency hopping operation, if not, whether the target frequency of the compressor is matched with the test frequency is judged, and the subsequent clamping operation is executed according to the matching result. Therefore, the frequency hopping control of the compressor can be performed on the basis of solving the problem that the stress of the outdoor unit pipeline group exceeds the standard.
Alternatively, as shown in connection with fig. 5, the target frequency of the compressor is obtained as follows:
s41, acquiring the change state of the current frequency of the compressor.
S42, if the change state indicates that the compressor is in a frequency stabilization state, a target time period of the frequency stabilization state of the compressor is acquired.
S43, determining the current frequency of the compressor corresponding to the target time period as the target frequency.
Therefore, the method obtains the change state of the current frequency of the compressor, obtains the target time period of the frequency stabilization state of the compressor when the change state indicates that the compressor is in the frequency stabilization state, and determines the current frequency of the compressor corresponding to the target time period as the target frequency. Therefore, the intelligent screening is carried out on the frequency of the compressor which possibly causes the overstress of the pipeline group, and the problem of the overstress of the pipeline group of the outdoor unit is further solved.
In practical application (as shown in fig. 8), fig. 8 shows a time-frequency variation curve of the compressor, the horizontal axis shows the operation time of the compressor, and the vertical axis shows the frequency of the compressor. Wherein the time-frequency profile of the compressor is determined by the type of compressor.
In the time-frequency change curve, a curve corresponding to the point A and the point B corresponds to the frequency-increasing state and the frequency-decreasing state of the compressor, and a curve corresponding to the point B to the point C corresponds to the frequency-stabilizing state of the compressor.
The time-frequency change curve can be used for acquiring the change state of the current frequency of the compressor, the frequency of the compressor is in an ascending state in the process from 0Hz to 109Hz, and is in a descending state in the process from 109Hz to 98Hz, and finally the operation at 98Hz is kept. The time period corresponding to the point B and the point C can be determined to be the target time period of the frequency stabilization state of the compressor according to the time-frequency change curve, so that the variable frequency air conditioner is determined to determine the current frequency of the compressor corresponding to the target time period as the target frequency.
As shown in fig. 6, the embodiment of the present disclosure further provides a compressor damping method for a variable frequency air conditioner configured with a compressor, a pipe group connected to the compressor, a supporting device installed at the bottom of the compressor, and a clamping device clamped to the outer wall of the supporting device. The method comprises the following steps:
s51, acquiring an information table, wherein the information table stores the test frequency of the compressor and the clamping force of a clamping device associated with the test frequency, and the test frequency and the clamping force are determined by the stress of the pipeline group.
S52, when the compressor is in the operation stage, the target frequency of the compressor is obtained.
And S53, if the target frequency of the compressor is matched with the test frequency, acquiring the operation duration of the target frequency of the compressor.
And S54, if the running time length is greater than or equal to the preset time length, matching the target clamping force corresponding to the target frequency from the information table.
S55, controlling the clamping device to perform clamping operation on the supporting device with the target clamping force so as to reduce vibration of the compressor.
By adopting the compressor damping method for the variable frequency air conditioner, under the condition that the target frequency is matched with the test frequency, the running time of the target frequency is acquired, if the running time is longer than or equal to the preset time, the target frequency can be determined to cause the stress of the pipeline group to exceed the standard, and then the subsequent step of matching the target clamping force is executed. Therefore, the problem that the stress of the outdoor unit pipeline group exceeds the standard can be effectively solved.
Optionally, the compressor damping method for the variable frequency air conditioner further comprises the following steps:
and if the operation time is less than the preset time, controlling the clamping device to be turned off.
Thus, if the operation duration of the target frequency of the compressor is smaller than the preset duration, the target frequency does not cause the stress of the pipeline group to exceed the standard, and the clamping device is not required to be controlled to perform clamping operation, so that the clamping device is controlled to be turned off.
The operation time length is determined according to the model of the variable frequency air conditioner.

By adopting the compressor damping device for the variable frequency air conditioner, when the damping operation is required to be carried out on the compressor, the target clamping force corresponding to the target frequency is matched from the information table, the clamping operation is carried out by the target clamping force, and the vibration of the compressor is reduced by enhancing the rigidity of the supporting device, so that the vibration of the pipeline group is reduced, and the problem of exceeding stress of the pipeline group of the outdoor unit is effectively solved.
