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. Through the control method, the problems of poor universality and poor user experience existing in an existing air conditioner control method can be solved. The control method comprises the steps that the temperature difference between indoor environment temperature and the set temperature is calculated; according to a fitting formula, frequency raising speed of a compressor in the frequency raising stage is calculated; and the compressor is controlled to raise frequency according to the frequency raising speed, specifically, the fitting formula is determined according to the corresponding relation between the temperature difference and the frequency raising speed of the compressor. The fitting formula is determined in advance, then the frequency raising speed of the compressor in the frequency raising stage is calculated according to the fitting formula, and thenthe compressor is controlled to raise the frequency according to the frequency raising speed. Through the control method of the air conditioner, the universality of the air conditioner and use experience of a user can be 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 cooling / heating and thus bring users a comfortable experience, the existing air conditioners usually increase the frequency of the compressor to a higher frequency ( such as upscaling 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 stable . However, the...
