Control method of air conditioner in refrigeration mode

Abstract

The invention relates to the technical field of air conditioners, in particular to a control method of an air conditioner in the refrigeration mode. The problems that an existing air conditioner control method is poor in universality and poor in user experience are solved. In order to achieve the aim, the control method in the refrigeration mode comprises the steps of obtaining indoor environmenttemperature; according to the fitting formula, calculating the frequency rising speed of a compressor in the frequency rising stage; and controlling the compressor to be subjected to frequency risingaccording to the frequency rising speed. The fitting formula is determined according to the corresponding relation of the indoor environment temperature and the frequency rising speed of the compressor. Through pre-determining of the fitting formula, according to the fitting formula, the frequency rising speed of the compressor at the frequency rising stage can be calculated, the compressor is controlled to be subjected to frequency rising according to the frequency rising speed, and the control method can improve the air conditioner universality and improves the user use experience.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner control method in cooling mode. 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 the air conditioner as an example, in order to meet the needs of users for rapid cooling and bring users a comfortable experience, the existing air conditioners generally make the compressor quickly increase in frequency to run at a higher frequency (such as frequency up 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...
