The invention discloses a compressor control method and device, a storage medium, a processor and a compressor. The method comprises the steps that the equivalent operation frequency of the compressoris detected; and based on the equivalent operation frequency, the conversion of the compressor between any following modes is determined: conversion between a low-load rate area and a medium-load rate area, conversion between the low-load rate area and a high-load rate area, and conversion between the medium-load rate area and the high-load rate area. The method solves the technical problem of difficult reduction of the minimum refrigerating capacity output of the compressor although the motor efficiency of the compressor can be improved through a mode of improving the motor counter electromotive force when the compressor is operated at low frequency in the prior art.
Description
technical field [0001] The invention relates to the field of compressor control, in particular to a compressor control method, device, storage medium, processor and compressor. Background technique [0002] At present, the rolling rotor type frequency conversion compressor used in the air conditioning system in the related art has the characteristics of a large cooling capacity output range, which can meet the needs of users for different cooling capacity output ranges. However, when the compressor operates at a low frequency, the compressor coefficient of performance (COP) is greatly reduced due to the sharp decay of the motor efficiency and the pump body efficiency. [0003] In response to the above-mentioned technical defects, some manufacturers have proposed to use the switching scheme of the motor winding connection mode to solve the problem that the efficiency of the compressor is greatly reduced when the compressor is running at low frequency. Ordinary conventional c...
