Be exemplified below a kind of embodiment, such as, by seven kinds of different frequency series of frequency configuration 1-7 level of the compressor of air-conditioner, 1
The higher limit of the frequency separation that level is corresponding is compressor full-power performance number, i.e. maximum power value；2 grades of corresponding frequency separations
Higher limit is compressor full load power 90%；The higher limit of 3 grades of corresponding frequency separations is compressor full load power
80%；The higher limit of 4 grades of corresponding frequency separations is the 70% of compressor full load power；5 grades of corresponding frequency separations
Higher limit is the 60% of compressor full load power；The higher limit of 6 grades of corresponding frequency separations is compressor full load power
50%；The higher limit of 7 grades of corresponding frequency separations is the 40% of compressor full load power, between the most adjacent two frequency series
