Abstract:
The present disclosure provides a compressor control method and control apparatus and a modular air conditioning unit. The modular air conditioning unit comprises at least one variable frequency air conditioning unit, the variable frequency air conditioning unit is provided with at least one compressor, and the compressor has at least one frequency efficient band sequentially distributed from low to high. The compressor control method comprises the following steps: detecting the load demand of the modular air conditioning unit; determining whether the output capability of the modular air conditioning unit meets the load demand; if the output capability does not meet the load demand, determining whether to turn on all the compressors, and if so, gradually increasing the operating frequencies of the compressors from the turn-on frequency to each frequency efficient band according to a set frequency increase rule, otherwise, turning on the compressors one by one according to a set order.
