Brief description of the drawings
Fig. 1 is the flow chart based on air-conditioning Torque Control method one embodiment of the invention；
Fig. 2 is based on second flow chart of embodiment of air-conditioning Torque Control method of the invention.
Specific embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, below with reference to drawings and Examples,
The present invention is described in further detail.
Fig. 1 is referred to, the figure show the flow chart of air-conditioning Torque Control method one embodiment of the present invention.
As schematically shown in Figure 1, the embodiment realizes that the method for air-conditioning Torque Control comprises the following steps the process for constituting.
Step 11：The current operation frequency of compressor is obtained, is obtained with the corresponding relation of stress threshold according to known frequency
The corresponding stress threshold of current operation frequency is taken, as current stress threshold；Obtain compressor exhaust pipe or compressor return air pipe
Current stress value on road.
Current operation frequency refers to the running frequency of the compressor when air-conditioning opens refrigeration or heating mode, can be passed through
The rotating speed of rotor during detection compressor operating, is then calculated by known formula again.Frequency and stress threshold
A kind of corresponding relation that corresponding relation is known, prestores, can easily get.Different frequency correspondences is incomplete
Stress threshold that is identical or differing completely.After current operation frequency is got, closed from frequency is corresponding with stress threshold
Determined in system with the stress threshold corresponding to current operation frequency, and as current stress threshold, so as to according to current stress
Threshold value makees further control.
Current stress value refers to the deformation quantity of the vibration of blast pipe or muffler during compressor operating.Currently should
Force value can be detected by the strain gauge being arranged on compressor exhaust pipe or compressor return air pipeline, by compressor air-discharging
The mechanical variables of the generation on pipe or compressor return air pipe are converted into electric signal, and then gathering electric signal by computer board is converted to
Stress value, specific test position can be determined by stress test.For example, test position is most leaned in compressor exhaust pipe
Near a pipe bent position of compressor in one pipe bent position, or compressor return air pipe of nearly compressor.Compressor drum
Running speed it is slower when, vibration of compressor is more violent, then, examined on compressor exhaust pipe or compressor return air pipeline
The stress value measured is larger, so when the running frequency of compressor is relatively low, the stress value for detecting is larger.
As the presently preferred embodiments, current stress value is obtained using following manner：Obtain first on compressor air-discharging pipeline
The second stress value on stress value and compressor return air pipeline, using the higher value in the first stress value and the second stress value as work as
Preceding stress value.
Step 12：Current stress value is made comparisons with current stress threshold；Current stress value is being met more than current stress
Variable torque control process is performed during the condition of threshold value, when meeting current stress value and being not more than the condition of current stress threshold,
Perform constant moment of force control process.
Variable torque control process refer to compressor output torque can follow air-conditioning system loading moment change
And change, constant moment of force control process refers to that the output torque of compressor is constant, does not follow the loading moment of air-conditioning system to become
Change and change.Variable torque control process and implementing for constant moment of force control process can not made herein using prior art
Elaborate.
Air-conditioning Torque Control is carried out by the way of the embodiment, due to when current stress value reflects compressor operating
Magnitude of vibrations, therefore, the current stress value and current stress threshold determined by step 11 make comparisons to determine which kind of power performed
Square control process.When current stress value is more than current stress threshold, show that the vibration of compressor currently operation is larger, then will be logical
Execution variable torque control process is crossed as torque compensation, the vibration of compressor can be effectively reduced；In current stress value not
During more than current stress threshold, show that the vibration of compressor currently operation is smaller, then can by performing constant moment of force control process
So that the vibration of compressor is reduced to required vibration standard.
As preferred embodiment, it is known that the corresponding relation of frequency and stress threshold be frequency range and stress threshold
Corresponding relation.For example, as it is known that frequency range be 5Hz ＜ f≤30Hz, corresponding stress threshold is 30 μ；Known frequency
Scope is 30Hz ＜ f≤40Hz, and corresponding stress threshold is 40 μ；Known frequency range is 40Hz ＜ f≤50Hz, and institute is right
The stress threshold answered is 50 μ；Known frequency range is 50Hz ＜ f≤60Hz, and corresponding stress threshold is 60 μ.It is determined that
The principle of the corresponding relation is, when the running frequency of compressor is bigger, the rotating speed of compressor drum is faster, illustrates compressor
Oscillation Amplitude it is relatively small, it is therefore desirable to larger stress threshold judges to perform variable torque or constant moment of force control process
Condition.
So, in the case where the current operation frequency of compressor is obtained, it is necessary first to determine belonging to current operation frequency
Frequency range；Then, the corresponding relation further according to known frequency range and stress threshold is obtained belonging to current operation frequency
Frequency range corresponding to stress threshold, as current stress threshold.For example, the current operation frequency for obtaining is 35Hz, category
In the frequency range of 30Hz ＜ f≤40Hz, can determine that current stress threshold is 40 μ by the corresponding relation of frequency and stress threshold
ɛ .If the current stress value for obtaining is 45 μ, more than the μ of current stress threshold 40, illustrate that vibration of compressor is larger, then pass through
Variable torque control process is performed, vibration of compressor is effectively reduced.
Air-conditioning Torque Control is carried out by the way of the embodiment, by the running frequency and compressor pipe that detect compressor
Stress value on road, the corresponding stress threshold adjustment compressor torque control of running frequency and different running frequencies according to compressor
Mode processed, efficiently solving prior art can not be reduced according to the defect of the vibration adjustment Torque Control mode of compressor
Because of the generation of the problem of vibration of compressor caused by torque overcompensation or undercompensation.
Referring to Fig. 2, the figure show the flow of another embodiment of air-conditioning Torque Control method proposed by the invention
Figure.
As shown in Fig. 2 the embodiment realizes that air-conditioning Torque Control method comprises the following steps constituted process：
Step 21：The current operation frequency of compressor is obtained, is made comparisons with first frequency threshold value and second frequency threshold value.
Current operation frequency refers to the running frequency of the compressor when air-conditioning opens refrigeration or heating mode, can be passed through
The rotating speed of rotor during detection compressor operating, is then calculated by known formula again.
Step 22：Judge whether current operation frequency is more than first frequency threshold value and no more than second frequency threshold value.If
It is then to perform step 23；If it is not, then performing step 24.
Step 23：Judge that current operation frequency is more than first frequency threshold value and no more than second frequency threshold value in step 22
When, the corresponding relation according to known frequency and stress threshold obtains the corresponding stress threshold of current operation frequency as currently should
Force threshold；Obtain the current stress value on compressor air-discharging pipeline or compressor return air pipeline, by current stress value with it is described
Current stress threshold is made comparisons；In condition of the current stress value more than current stress threshold, variable torque control process is performed；
When current stress value is not more than the condition of current stress threshold, constant moment of force control process is performed.
The step implements the description for referring to Fig. 1 embodiments.
Step 24：When step 22 judges that current operation frequency is not more than first frequency threshold value, variable torque control is performed
Process；When step 23 judges that current operation frequency is more than second frequency threshold value, constant moment of force control process is performed.
The size of the current operation frequency of compressor determines the size of vibration of compressor, compressor running frequency compared with
When low, the vibration of compressor is general in the case, variable torque control to be performed to compressor than larger, will can be compressed
The vibration of machine carries out the critical field that compulsory compensation control can reach vibration；When the running frequency of compressor is higher, compression
The rotor of machine runs at high speed, and compressor Oscillation Amplitude in itself is smaller, therefore only takes constant moment of force to control just enough to mend torque
The vibration of compressor is set to reach the critical field of vibration after repaying.Therefore, by setting first frequency threshold value and second frequency threshold value,
And first frequency threshold value is less than second frequency threshold value, by current operation frequency and first frequency threshold value and second frequency threshold value
Compare, accurately and rapidly judge which kind of Torque Control performed when can be relatively low or higher in running frequency, reduce because of torque
Overcompensation or the generation of under-compensated phenomenon.First frequency threshold value and second frequency threshold value are known, default values, are
Reflect a threshold value of current operation frequency size.Preferably, first frequency threshold value is 5Hz, and second frequency threshold value is 60Hz.
If the current operation frequency of compressor is relatively low, vibration of compressor is generally large in the case of this, if for example, obtaining
When the current operation frequency for taking is less than 5Hz, no matter the size of the stress value of current compressor pipeline, is performed both by variable torque control
Process；If the current operation frequency of compressor is higher, the vibration of compressor is typically small, if for example, the current fortune for obtaining
When line frequency is more than 60Hz, then constant moment of force control process is performed.
Also, in some other embodiment, performing variable torque control process or performing constant moment of force control process
When, the current stress value on compressor air-discharging pipeline or compressor return air pipeline is still obtained, and stress value ratio is exited with setting
Compared with if current stress value is not more than setting when exiting stress value, illustrating that the vibration amplitude produced during compressor operating is smaller, just
Variable torque control process or constant moment of force control process can be exited.Wherein, it is also default one that stress value is exited in setting
Known stress value, be reflection vibration whether a less numerical value.The purpose for performing the process is in order to avoid appearing in compression
The phenomenon of the overcompensation occurred when not needing torque compensation when machine runs at high speed.
As preferred embodiment, because the frequency during compressor operating is real-time change, due to compressor
Frequency range described in frequency and stress threshold are corresponding relations, therefore, when compressor frequency frequency range critical value
When fluctuating up and down, such as when the current operation frequency for detecting fluctuates between 28Hz-32Hz, its corresponding stress threshold is 30
Fluctuated between μ and 40 μ two values, thus compressor just appear in variable torque control process and constant moment of force control process it
Between frequent switching, it is impossible to when ensureing compressor operating can effectively by torque compensation reach reduce vibration purpose.Therefore,
Also need to further judge whether to switch Torque Control process more than the duration of stress threshold according to current stress value.
Specifically, as the presently preferred embodiments, default switching condition includes：
Current stress value more than current stress threshold condition and meet current stress value more than current stress threshold it is lasting when
Between more than the setting duration when, then perform the variable torque control process；
Current stress value is not more than the condition of the current stress threshold and meets current stress value and is not more than the current stress
When the duration of threshold value is more than the setting duration, then perform the constant moment of force control process.
Preferably, the setting duration is not less than 5s.Namely：In condition of the current stress value more than current stress threshold
Duration when reaching more than 5s, perform variable torque control process.Likewise, being not more than stress threshold in current stress value
Duration when reaching more than 5s, then switch to perform constant moment of force control process.
The various embodiments described above from compressor operating frequency to the angle of pipeline stress influence, by detecting compressor
Stress value in running frequency and compressor circuit, the corresponding stress threshold of running frequency and different running frequencies according to compressor
Value adjustment compressor Torque Control mode, efficiently solving prior art can not be according to the vibration adjustment torque control of compressor
The defect of mode processed, reduces because of the generation of the problem of vibration of compressor caused by torque overcompensation or undercompensation.
The above embodiments are merely illustrative of the technical solutions of the present invention, rather than is limited；Although with reference to foregoing reality
Example is applied to be described in detail the present invention, for the person of ordinary skill of the art, still can be to foregoing implementation
Technical scheme described in example is modified, or carries out equivalent to which part technical characteristic；And these are changed or replace
Change, do not make the spirit and scope of the essence disengaging claimed technical solution of the invention of appropriate technical solution.
