Control method of air conditioner

Abstract

The invention relates to the technical field of air conditioners, in particular to a control method of an air conditioner. According to the control method, the problems that an existing control methodof an air conditioner is poor in universality and poor in user experience. Therefore, the control method comprises the following steps that the rotating speed of an inner fan is acquired; according to the first fitting formula, the valve closing speed of an expansion valve is calculated; according to the second fitting formula, the frequency rising speed of a compressor in the frequency rising stage is calculated; the expansion valve is controlled to be closed according to the valve closing speed to reach the target opening degree; and when the expansion valve is controlled to closed according to the valve closing speed to reach the target opening degree, or before or after the expansion valve is controlled to closed according to the valve closing speed to reach the target opening degree,the compressor is controlled to perform frequency rising according to the frequency rising speed. Through the control mode, the control method of the air conditioner can improve the universality of the air conditioner, and the use experience of the user is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner control method. Background technique [0002] With the improvement of living standards, people have higher and higher requirements for the quality of life, and this requirement is particularly evident in household appliances. Taking an air conditioner as an example, in order to meet the needs of users for rapid heating and thus bring users a comfortable experience, when the existing air conditioner is just turned on, the frequency of the compressor is generally increased to a higher frequency (such as frequency to the maximum operating frequency). In the process of the compressor rapidly rising to high frequency, in order to ensure normal oil return, the compressor is usually forced to continue running at a certain or certain fixed frequency (oil return frequency) for a period of time, and continue to increase the frequency after the oil return is sta...
