Abstract

The invention discloses an air conditioner oil return control method, an air conditioner and a readable storage medium. The air conditioner oil return control method includes: receiving an instruction to enter a high-temperature sterilization mode, controlling a heat exchange component to operate in a heating mode; obtaining the current Operating parameters, determine whether to operate the oil return mode according to the current operating parameters; if it is determined to operate the oil return mode, then obtain the first operating frequency of the compressor, and obtain the frequency increase rate according to the first operating frequency; control the compressor to The frequency increase rate increases from the first operating frequency to the preset oil return frequency. When the air conditioner enters the high-temperature sterilization mode and operates in the oil return mode, the present invention can prevent the pressure of the air conditioner from increasing due to the excessively fast frequency increase of the compressor, thereby ensuring the reliability of the air conditioner.

Description

technical field [0001] The invention relates to the technical field of heat exchange, in particular to an air conditioner oil return control method, an air conditioner and a readable storage medium. Background technique [0002] At present, most of the air conditioners have a high-temperature sterilization mode. When the air conditioner enters the high-temperature sterilization mode, if it is detected that it needs to enter the oil return mode during this period, the conventional oil return method is to run the compressor at high frequency to improve the air conditioner cycle. The refrigerated oil in the pipeline is brought back to the compressor, but due to frequency fluctuations, this process will affect the maintenance of the temperature of the heat exchange components. At the same time, a sudden increase in frequency will increase the pressure of the air conditioner, which is not conducive to the reliability of the air conditioner. [0003] Therefore, it is necessary to ...
