Compressor frequency control method and device, air conditioner and storage medium

Abstract

The invention provides a compressor frequency control method and device, an air conditioner and a storage medium, and relates to the technical field of compressor control. According to the method, theoperating mode of the air conditioner, the current outdoor environment temperature, the current indoor environment temperature and the current wind gear are acquired, and the maximum operating frequency of a compressor is determined based on the operating mode, the current outdoor environment temperature and the current indoor environment temperature. Due to the fact that the maximum operating frequency of the compressor is reasonably determined through the outdoor environment temperature, the indoor environment temperature and the operating mode of the air conditioner, the maximum operatingfrequency of the compressor can be more suitable for the current operating environment, the compressor can be guaranteed to work normally in an extreme operating condition (ultra-temperature or ultralow temperature), the compressor has the more suitable operating frequency at the normal environment temperature, the air conditioner is more energy-saving and lower in noise, and meanwhile, the excessively high operating frequency of the compressor is avoided, so that the service life of the compressor is prolonged and the reliability of an air conditioning system is guaranteed.

Description

technical field [0001] The present invention relates to the technical field of compressor control, in particular to a compressor frequency control method and device, an air conditioner and a storage medium. Background technique [0002] With the continuous development of the society and the continuous progress of the economy, air conditioners have entered thousands of households, bringing a good experience to more and more users. At the same time, with the continuous innovation of technology, inverter air conditioners are one of the mainstream models currently on the market. The frequency of the compressor of the inverter air conditioner can be changed according to the needs of the user and the change of the environment. [0003] In the prior art, in order to ensure that the heating / cooling capacity does not decrease too much in ultra-low temperature and high temperature environments, the maximum operating frequency of the compressor is designed to be relatively high and is...
