The neighbouring Frequency point of running frequency is as the running frequency of compressor.Wherein, the conjunction of the pre-conditioned compressor for convertible frequency air-conditioner
Amplitude that lattice Frequency point is corresponding and stress.The most pre-conditioned amplitude for qualified Frequency point and stress are respectively less than equal to 2.
Specifically, after generating resonant frequency table, the when of normally use after air-conditioning, such as, select system user
The when of chill formula (non-mute pattern), if needing to run at certain Frequency point A, it should first inquire about this Frequency point A's
It is pre-conditioned whether amplitude, stress meet.If meeting pre-conditioned, then using required running frequency as the operation of compressor frequency
Rate；If being unsatisfactory for pre-conditioned, near this point, finding one close the Frequency point B that symbol requires, use B to substitute A as pressure
The running frequency of contracting machine.Such as, when off-premises station judges to need to operate in 30Hz when, table look-up and learn that amplitude, stress are defective,
The most nigh Frequency point reselects, and uses the Frequency point of satisfactory 33Hz to replace 30Hz to run.
It addition, in an example of the present invention, in addition it is also necessary to carry out spot measurement, i.e. say, when air-conditioning stable operation is at certain
The when of individual some C, the amplitude of up-to-date harmonic wave, stress measurement out, and record in resonant frequency table.If this point

Step S301, starts.
Step S302, the compressor of convertible frequency air-conditioner prepares running frequency point A.
Specifically, when user selects refrigeration mode (non-mute operation) when, off-premises station judges to need to operate in frequency
The when of some A, then prepare running frequency point A.
Step S303, tables look-up.
Inquire about amplitude corresponding to the running frequency preparing to run in resonant frequency table and stress
Step S304, it is judged that whether amplitude, stress meet requirement.If it is, continue executing with step S305；Otherwise perform
Step S309.
Step S305, stable operation.
Step S306, sampled operational.
Step S307, result preserves.
Step S308, it is judged that whether amplitude, stress meet requirement.If it is, return step S305；Otherwise perform step
S309。
Step S309, selects close Frequency point B.
Specifically, the satisfactory Frequency point B of searching one near defective Frequency point A, use Frequency point B to substitute
Frequency point A runs.
After execution of step S309, return step S305.Specifically, off-premises station stable operation is 30Hz when, logical
Crossing acceleration transducer sampling, processor carries out computing judgement to sampled result, it is judged that whether amplitude and stress still conform to want
Ask, if it is determined that still conform to require but result change, then update resonant frequency table record.Want if strictly do not met
Ask, the process again tabled look-up, reselect a Frequency point, and again judge.
Air-conditioning is being installed, is being moved and after maintenance, is likely to resonance point is produced impact, so in these cases, all
Should measure the most comprehensively, update resonant frequency table.It addition, life-time service also can make resonant frequency offset, specifically
Ground, during normal use, frequency resonance point changes, and finds that the measurement result of 33Hz changes, and such as measurement result is for shaking
Width=3, stress=2, now air-conditioning should update the parameter of resonant frequency table, as shown in table 2.
Table 2
| Frequency | Amplitude | Stress |
| 33Hz | 3 | 2 |
Specifically, by the record change of 33Hz it is recognised that what routine use record can would generally make originally can to use
Frequency point becomes fewer and feweri, but it practice, the skew of Frequency point, the some E of original weak effect can be made to change toward good trend,
But owing in resonant frequency table, E is not conform to lattice point, automatically avoid in using need not, so air-conditioning has not known the situation of E
Through making moderate progress, so in Ji Lu, E point does not still conform to lattice point.Along with the time of use is more and more longer, underproof Frequency point more comes
The most, using effect can be affected, updated by air-conditioning remote control so user needs actively to update resonant frequency table, such as user
Resonant frequency table, or air-conditioning timing automatic renewal resonant frequency table.
