The resonance point jump adaptive approach of the convertible frequency air-conditioner proposing according to first aspect present invention embodiment is described below with reference to accompanying drawing.
As shown in Figure 1, the present invention is the resonance point jump adaptive approach of the convertible frequency air-conditioner of embodiment, comprises the steps:
Step S1: the running frequency scope of obtaining the compressor of convertible frequency air-conditioner.
Wherein, the running frequency scope of compressor is [MIN, MAX], for example, be [0.1,150] (unit: Hz), i.e. speech, and compressor minimum operation frequency is 0.1Hz, maximum running frequency is 150Hz.
Step S2: the running frequency of controlling compressor is moved by the low-limit frequency of running frequency scope.
Step S3: under running frequency, measure accekeration and the acceleration direction of at least one preset component resonance of convertible frequency air-conditioner, and according to standard amplitude and the standard stress of accekeration and the resonance of acceleration direction calculating.
In an embodiment of the present invention, under current running frequency, utilize acceleration transducer to measure accekeration and the acceleration direction of at least one preset component resonance of convertible frequency air-conditioner, and according to standard amplitude and the standard stress of accekeration and the resonance of acceleration direction calculating.Wherein, stress=acceleration * quality, because the quality of object is constant, so the variation of acceleration can represent with the variation of stress.Particularly, the parameter measuring by acceleration transducer is accekeration and acceleration direction, accekeration and acceleration direction being carried out to computing, can obtain the motion conditions of at least one preset component, is exactly amplitude, stress etc. in all directions specifically.Wherein, at least one preset component comprises one or more in off-premises station blast pipe, off-premises station air inlet pipe, compressor and the outdoor cabinet shell of convertible frequency air-conditioner.Be understandable that, the above-mentioned example to preset component is not limited to this, and the resonant component that preset component has influence on can also work according to convertible frequency air-conditioner time arranges, and repeats no more.
Step S4: preserve the standard amplitude and the standard stress that calculate in step S3, running frequency is increased to preset step-length, repeating step S3 and S4, until running frequency is the highest frequency of running frequency scope.
Wherein, default step-length can be 0.1Hz, it should be noted that, this default step value, just for example, is not limited to this value.
In one embodiment of the invention, after step S4, also comprise the steps: that corresponding standard amplitude and the standard stress of each running frequency to obtaining adds up to generate resonant frequency table.
Below in conjunction with Fig. 2, take running frequency scope as [0.1,150], (unit: Hz) is described resonant frequency table generative process for example.
The running frequency scope of convertible frequency air-conditioner is [0.1,150] (unit: Hz), and smallest incremental is 0.1Hz, i.e. speech, and default step-length is 0.1Hz, after first installation, air-conditioning is measured comprehensively, as shown in Figure 2.
Step S201, starts.
Step S202, the compressor of convertible frequency air-conditioner moves with low-limit frequency.
In this example, the compressor minimum operation frequency of convertible frequency air-conditioner is 0.1Hz.
Step S203, the compressor of convertible frequency air-conditioner keeps stable operation.
Step S204, sampling computing.
After execution of step S203, acceleration transducer measure that air-conditioning resonance produces accekeration and acceleration direction, air-conditioning according to standard amplitude and the standard stress of the accekeration recording under current running frequency and the resonance of acceleration direction calculating.
Step S205, result is preserved.

Step S206, frequency increases.
Particularly, after execution of step S205, running frequency increases to preset step-length 0.1Hz.
Step S207, whether determination frequency is greater than highest frequency.If it is carry out S208; Otherwise return to step S203.
Particularly, judge that running frequency is greater than highest frequency 150Hz, if it is carries out S208; Otherwise return to step S203.
Step S208, finishes.
Particularly, until the parameter in [0.1,150] scope is measured comprehensively, generate resonant frequency table, as shown in table 1, wherein, stress and amplitude are the important parameters that affects service life, therefore stress and amplitude are saved in resonant frequency table.

It should be noted that, air-conditioning, can be according to resonant frequency table in the time of quiet operational mode, selects the Frequency point operation of a low noise.For example, quiet point selection amplitude and stress are equal to 1 Frequency point.
In one embodiment of the invention, generating after resonant frequency table, also comprising the steps: the required running frequency of the compressor that detects convertible frequency air-conditioner; In resonant frequency table, search standard amplitude corresponding to required running frequency and standard stress, and whether criterion amplitude and standard stress meet pre-conditioned; If so, continue operation, otherwise select the running frequency of the Frequency point contiguous with required running frequency as compressor.Wherein, the pass frequency of the pre-conditioned compressor for convertible frequency air-conditioner is put corresponding amplitude and stress.For example pre-conditioned amplitude and stress for qualified Frequency point is all less than or equal to 2.
Particularly, after generating resonant frequency table, in the time of air-conditioning normal use later, for example, when user selects refrigeration mode (non-silent mode), if need to be in certain Frequency point A operation, should first inquire about this Frequency point A amplitude, that whether stress meets is pre-conditioned.If meet pre-conditioned, the running frequency using required running frequency as compressor; If do not meet pre-conditionedly, near this point, find one and close the Frequency point B that symbol requires, use the running frequency of the alternative A of B as compressor.For example, in the time that off-premises station judgement need to operate in 30Hz, table look-up and learn that amplitude, stress are defective, nigh Frequency point reselects, and uses the Frequency point of satisfactory 33Hz to replace 30Hz operation.
In addition, in an example of the present invention, also need to carry out spot measurement, i.e. speech, when air-conditioning stable operation is in the time that certain puts C, up-to-date humorous wave amplitude, stress measurement out, and is recorded in resonant frequency table.If the amplitude of this C does not meet the amplitude requirement of pass frequency point, look in addition one to close the alternative C of some D that symbol requires.
The frequency selection course that air-conditioning is generated to the normal use afterwards of resonant frequency table below in conjunction with Fig. 3 is described.
Step S301, starts.
Step S302, the compressor of convertible frequency air-conditioner is prepared running frequency point A.
Particularly, in the time that user selects refrigeration mode (non-quiet operation), when off-premises station judgement need to operate in Frequency point A, prepare running frequency point A.
Step S303, tables look-up.
In inquiry resonant frequency table, prepare corresponding amplitude and the stress of running frequency of operation
Step S304, judges whether amplitude, stress meet the demands.If so, continue execution step S305; Otherwise execution step S309.
Step S305, stable operation.
Step S306, sampling computing.
Step S307, result is preserved.
Step S308, judges whether amplitude, stress meet the demands.If so, return to step S305; Otherwise execution step S309.
Step S309, selects approaching Frequency point B.
Particularly, near satisfactory Frequency point B of searching defective Frequency point A, frequency of utilization point B alternative frequency point A operation.
After execution of step S309, return to step S305.Particularly, off-premises station stable operation, in 30Hz, is sampled by acceleration transducer, processor carries out computing judgement to sampled result, judge whether amplitude and stress still meet the requirements, if judgement still meets the requirements but result changes to some extent, upgrade the record of resonant frequency table.If be undesirable really, the process of again tabling look-up, reselects a Frequency point, and judgement again.
Air-conditioning, after installing, move and keeping in repair, all likely exerts an influence to resonance point, so in these cases, all should once measure comprehensively, upgrades resonant frequency table.In addition, long-term use also can make resonant frequency be offset, particularly, during normal use, frequency resonance point changes, and finds that the measurement result of 33Hz has changed, for example measurement result is amplitude=3, stress=2, and now air-conditioning should upgrade the parameter of resonant frequency table, as shown in table 2.
Table 2
Frequency Amplitude Stress
33Hz 3 2
Particularly; change and can know by the record of 33Hz; routine use record can make original operable Frequency point become fewer and feweri conventionally, but in fact, the skew of Frequency point; can make the some E of original weak effect change toward good trend; but because E in resonant frequency table does not conform to lattice point, in use, automatically avoid need not, so air-conditioning does not know that the situation of E makes moderate progress; so in record, E point does not still conform to lattice point.Along with service time is more and more longer, underproof Frequency point is more and more, can affect result of use, so user need to initiatively upgrade resonant frequency table, for example user upgrades resonant frequency table by air-conditioning remote control, or the timing automatic renewal resonant frequency of air-conditioning table.
For this reason, in one embodiment of the invention, upgrade resonant frequency table every predetermined period.Wherein, predetermined period can be 5000 hours, i.e. speech, and air-conditioning once after working hours update times 5000, automatically upgrades resonant frequency table in distance.
According to the resonance point jump adaptive approach of the convertible frequency air-conditioner of the embodiment of the present invention; can effectively avoid air-conditioning in prior art installing, mobile, maintenance and use for a long time resonance point skew after cause the shortcoming that cannot avoid resonance; thereby protection machinery, the life-span of prolongation air-conditioning.
