COMPRESSOR CONTROL METHOD AND SYSTEM, AND AIR CONDITIONER

WIPO Patent Application WO/2023/011355

A1

The present invention relates to the technical field of air conditioner control, and particularly provides a compressor control method and system, and an air conditioner, to solve the problem that a compressor parameter offset may lead to a compressor control failure. Accordingly, the compressor control method of the present invention comprises: according to a result of comparison between a variable frequency control parameter of a compressor in actual operation and a preset initial value of the variable frequency control parameter, obtaining an offset of the variable frequency control parameter; determining, according to the offset, whether to pre-correct the variable frequency control parameter; and further determining, according to compressor monitoring parameters before and after the pre-correction, whether to perform final correction on the variable frequency control parameter. The offset of the variable frequency control parameter and the compressor control failure caused by degradation of material characteristics due to long-term operation of the compressor can be avoided.
