Abstract

The invention discloses an air conditioner, an indoor unit electronic expansion valve control method and device of the air conditioner and a computer readable storage medium, and the method comprises the steps that after the air conditioner is started, changes of indoor side refrigerants are monitored in real time; judging whether the outdoor unit of the air conditioner enters an oil return state or not based on the change of the indoor side refrigerant; and if it is judged that the air conditioner outdoor unit enters the oil return state, an air conditioner indoor unit electronic expansion valve is adjusted to adapt to oil return of the air conditioner outdoor unit. The air conditioner indoor unit electronic expansion valve control method has the advantages that the service life of the compressor is prolonged, and the working reliability of the air conditioner is improved.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to an air conditioner and its indoor unit electronic expansion valve control method, equipment and computer-readable storage medium. Background technique [0002] When the air conditioner indoor unit and the air conditioner outdoor unit do not communicate with each other, the air conditioner indoor unit cannot directly obtain the information of whether the air conditioner outdoor unit enters the oil return. At this time, if the outdoor unit of the air conditioner enters the oil return state, the indoor unit of the air conditioner will still be controlled according to normal operation, and then the electronic expansion valve of the indoor unit of the air conditioner will not be adjusted accordingly, resulting in poor oil return for a long time, causing the compressor to wear or The temperature and pressure of the whole machine are too high to cause shutdown and reduc...
