Air conditioner control method

Abstract

The invention relates to the technical field of air conditioners, in particular to an air conditioner control method. The problems that an existing air conditioner control method is poor in universality and poor in user experience are solved. The control method comprises the steps of obtaining the rotating speed of an inner draught fan; according to the first fitting formula, calculating the valveclosing speed of an expansion valve; according to the second fitting formula, calculating acceleration of an outer draught fan; according to the third fitting formula, calculating the frequency increasing speed of the frequency increasing stage; controlling the expansion valve to be closed to the target opening degree according to the valve closing speed; controlling the outer draught fan to be subject to speed increasing to the target rotating speed according to the acceleration; preferably, when the expansion valve is closed to the target opening degree, and the outer draught fan is subjectto speed increasing to the target rotating speed, controlling a compressor to be subject to frequency increasing according to the frequency increasing speed. Through the above control mode, the air conditioner control method can improve the air conditioner universality, 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...
