More than or equal to the number of times of the first pre-set current value；
Running current value and pre-set current value are compared, when running current value reaches pre-set current value, then judged
Currently occurs the state for reaching larger current under height output capability state, and then running current value is more than or equal to for air-conditioning
The number of times of first pre-set current value is updated.The running current value of outdoor unit when running current value is operation of air conditioner；First
Pre-set current value is the default current value as reference, by by the comparison of running current value and the first pre-set current value, can
To judge whether air-conditioning currently the situation for reaching larger current occurs under height output capability state.For example, the first default electricity
Flow valuve is that the running current value got after 35A, operation of air conditioner is 38A, and running current value is more than the first pre-set current value, then more
New running current value is more than or equal to the number of times of the first pre-set current value, this time running current value will be more than the first predetermined current
The number of times of value is recorded.

Number is contrasted, and when times N reaches preset times, i.e., when more than or equal to preset times, the running frequency to air conditioner is entered
Row reduction.Wherein, when occurring running current value first and reaching pre-set current value, then this number of times is recorded as N=1, and
Start to start timer record preset time, running current value in preset time is recorded in preset time and reaches pre-set current value
Number of times.The increase of the running frequency of air conditioner can cause the increase of running current, and then cause the increase of air-conditioning fan-out capability；
When electric current is excessive, because the startup of the current protection measures of air conditioner causes air-conditioning fan-out capability to be carried out with the fluctuation of electric current
Frequent fluctuation, the increase of the running frequency by limiting air conditioner reaches entering to the frequent fluctuation phenomenon of air-conditioning fan-out capability
The effect of row control, within a preset time interval, when running current value reaches that the number of times of the first pre-set current value is more than or equal to
During preset times, down conversion process is carried out to running frequency, so that the frequent fluctuation to air-conditioning fan-out capability is controlled.For example,
When occurring running current value first and reaching pre-set current value, now cumulative number is 1, and opens the preset time of timing first, is 3
Minute, continue to record running current value in 3 minutes and reach the first pre-set current value metering number, if except running current value first reaches
To beyond pre-set current value, accumulative number of times is 3 times, then cumulative number is 4 times in final 3 minutes；If preset times are 3 times,
Then accumulative number of times now has reached preset times, the running frequency of the reduction air conditioner is carried out, specifically, running frequency
Such as 50Hz, reduces default frequency 2Hz, calculates A-Z=50Hz-2Hz=48Hz, the operation frequency that the 48Hz drawn is set to
Rate value.Within a preset time interval, if the number of times that the running current value of record is more than or equal to pre-set current value is less than default time
Number, then judge that the running current value of air conditioner does not occur frequent fluctuation phenomenon, then is further more than or waits to running current value
It is zeroed out, shows so that air conditioner rejudges running frequency with the presence or absence of frequent fluctuation in the number of times of the first pre-set current value
As.
Step S40, the number of times that the running current value is more than or equal to pre-set current value is reset.
After being reduced every time to running frequency value, then it is more than or equal to default electricity to recorded running current value
The number of times of flow valuve is zeroed out.After being zeroed out to the number of times, air conditioner can in real time or timing is entered to running current value
Row is reacquired, and compares running current value and the first pre-set current value, and record running current value reaches pre-set current value again
Number of times, so as to judge after being adjusted to running frequency, the running frequency of air conditioner whether also in frequent fluctuation state,
If there are still frequent fluctuation, further can be adjusted to running frequency.In addition, starting shooting or shutting down in the air conditioner
When, the number of times that the running current value is more than or equal to the first pre-set current value is reset.When air conditioner is run, to air conditioner
The progress that the running current value of outdoor unit understands real-time or timing is obtained, and further judges whether running frequency deposits by computing
In frequent fluctuation；In calculating process, time of the first pre-set current value can be reached to running current value within a preset time interval
Number is recorded, if carrying out power-off operation within a preset time interval in calculating process, the saved number of times is such as
Fruit is not resetting after starting shooting again, then can influence the accuracy with the presence or absence of the judgement of fluctuation, institute to air conditioner running frequency
So that in the start of air conditioner or when shutting down, time of the first pre-set current value is reached to the running current value that air-conditioner system is recorded
Number is zeroed out, to ensure after starting shooting again again to accuracy of the air conditioner running frequency with the presence or absence of the judgement of fluctuation.
In the present embodiment, by the way that the running current value in preset time being reached to, the number of times of pre-set current value is secondary with presetting
Number is compared, and when running current value reaches that the number of times of pre-set current value is more than preset times, judges that running frequency has ripple
It is dynamic, then running frequency is reduced, if the running frequency after reduction detects the situation for still having fluctuation by algorithm, repeated
The computing of frequency reducing is carried out, untill running frequency reaches stabilization, by the stabilization of operation control running frequency, and then makes air-conditioning
The fan-out capability of device reaches stable output, so as to realize the stable operation of air conditioner, it is ensured that it is reliable that air-conditioner system is run
Property, it is to avoid air conditioner causes running frequency frequently to lift due to current protection measures, so that fan-out capability frequent fluctuation, makes
Air-conditioner system is in unstable fluctuation status, influences Air-condition system control, the problem of having a strong impact on the reliability of system.

Value is more than first pre-set current value；
After being obtained to the running current value of air-conditioner outdoor unit, whether the second predetermined current is more than to running current value
Value judged, wherein the second pre-set current value is the safe operation threshold value of outdoor unit electric current, and the second pre-set current value is more than the
One pre-set current value.If running current value is more than the second pre-set current value, system can judge that running current value has exceeded air-conditioning
The safe operation threshold value of device outdoor unit operation, if running current value is not less than the second pre-set current value, system judges operation electricity
Flow valuve is still in the threshold range of safety.When the running current value is less than or equal to second pre-set current value,
Described in performing when the running current value is more than or equal to the first pre-set current value, update the running current value and be more than or wait
The step of the number of times of the first pre-set current value；If running current value is less than or equal to second pre-set current value, judge
The running current value of air conditioner is in the range of safe operation threshold value, then proceed step S20 is to running current value
The no judgement for being more than or equal to the first pre-set current value, and then it is more than or equal to time of the first pre-set current value to running current value
Number is recorded.
Step S60, when the running current value is more than second pre-set current value, exports warning message and shuts down.
If running current value reaches the second pre-set current value, it is determined as that the running current value of air-conditioner outdoor unit reaches
Or exceeded the secure threshold of electric current, then now air-conditioner outdoor unit is shut down, and exports warning message, to point out air-conditioning to go out
Now abnormal, need to further carry out debugging maintenance can run.
In the present embodiment, by setting the second pre-set current value, and the running current value got is preset with second
Whether current value is compared, so as to judge running current value in the safe operation current range less than the second pre-set current value
It is interior, by determining that the running current value of air conditioner is in the range of the electric current of safe operation, so that it is guaranteed that the safety of air conditioner

The running frequency that the air conditioner frequency adjustment method reduces the air conditioner includes：
Step S31, obtains the number of times of the running frequency of the reduction air conditioner；
Step S32, is less than default frequency reducing number of times in the number of times for reducing the running frequency of the air conditioner, default according to first
The running frequency of air conditioner described in amplitude reduction；
The number of times of reduction air conditioner running frequency is obtained, and compares number of times and the default frequency reducing time of air conditioner running frequency
Number, if the number of times of reduction air conditioner running frequency is less than default frequency reducing number of times, air conditioner is reduced according to the first predetermined amplitude
Running frequency, wherein the first predetermined amplitude is to carry out reduction frequency values to running frequency.For example, default frequency reducing number of times is 15 times,
The number of times that operation of air conditioner frequency is reduced after renewal is 3 times, and the first predetermined amplitude is 2Hz, then according to each 2Hz amplitude to operation
Frequency is reduced.
Step S33, when reducing the number of times of running frequency of the air conditioner more than or equal to default frequency reducing number of times, according to
Second predetermined amplitude reduces the running frequency of the air conditioner, wherein, first predetermined amplitude is less than the described second default width
Degree.
If the number of times for reducing air conditioner running frequency is more than or equal to default frequency reducing number of times, the first predetermined amplitude is judged

The number of times of operation of air conditioner frequency is 15 times, and the first predetermined amplitude is 2Hz, and the second predetermined amplitude is 5Hz, then according to each 5Hz's
Amplitude is reduced to running frequency.
In the present embodiment, by the comparison of the number of times and default frequency reducing number of times that reduce running frequency, if the number of times reaches
Default frequency reducing number of times, then judge that the first predetermined amplitude value for carrying out frequency reducing to running frequency is smaller, frequency reducing is less efficient, by inciting somebody to action
Second predetermined amplitude value replaces the first predetermined amplitude value, increases the frequency reducing amplitude to running frequency, so that running frequency value exists
The number of times of frequency reducing is reduced when when carrying out frequency reducing compared to using less first predetermined amplitude value, improves and frequency is run to air conditioner
