It is that the continuous working period is more than or equal to the first preset time and current operation frequency illustrates frequency conversion more than or equal to predeterminated frequency
The object run electric current of compressor is too small, and frequency-changeable compressor is unable to reach design temperature requirement, therefore, it is necessary to increases frequency conversion compression
The object run electric current of machine.
Further, in one embodiment of the invention, can be by the target after renewal when frequency-changeable compressor is shut down
The object run electric current of frequency-changeable compressor when running current is as outdoor unit start next time.
Further, in one embodiment of the invention, object run electric current is being repaiied according to electric current correction
Just can also comprise the following steps after updating object run electric current i.e. step S6：
S7, it will be zeroed in the continuous working period.
It should be noted that in one embodiment of the invention, step S1 to step S6, or step S1 to step S7
It can be carried out with circulating repetition, therefore, in the step s 7, will be zeroed in the continuous working period can ensure in next working cycles
The continuous working period of acquisition is zero-based, thereby may be ensured that the frequency-changeable compressor running frequency of the embodiment of the present invention
The reliability of adjusting method.
To sum up, the adjusting method of the frequency-changeable compressor running frequency of the embodiment of the present invention can be in obstructed in convertible frequency air-conditioner
During the heating mode of news, according to the continuous working period of the capacity of water of outdoor unit and frequency-changeable compressor, current operation frequency, most
The parameters such as big running frequency intelligently automatically adjust the running frequency of frequency-changeable compressor, the ability of frequency-changeable compressor is sent out in time
Wave, be rapidly reached design temperature.
The adjusting method of frequency-changeable compressor running frequency according to embodiments of the present invention, made detecting that convertible frequency air-conditioner is in
During heat pattern, according to the running frequency of the object run current regulation frequency-changeable compressor of the frequency-changeable compressor of acquisition, and when judgement
When continuous working period is more than or equal to the first preset time and current operation frequency and is more than or equal to predeterminated frequency, acquisition electric current
Correction, and object run electric current is updated according to electric current correction, so as to realize automatically adjusting for frequency-changeable compressor running frequency.
The adjusting method of the frequency-changeable compressor running frequency can pass through autonomous learning in the case that machine and outdoor unit do not communicate indoors
To automatically adjust the running frequency of frequency-changeable compressor to reach and maintain design temperature, reduce control parameter transmitting procedure, can
By property height.
