Control method of air conditioner in heating mode

Abstract

The invention relates to the technical field of air conditioners, in particular to a control method of an air conditioner in a heating mode. The control method of the air conditioner in the heating mode is used for solving the problem that an existing control method of the air conditioner is poor in universality and user experience. In order to achieve the purpose, the control method of the air conditioner in the heating mode comprises the steps that the indoor environment temperature is acquired; the frequency raising speed of a compressor in the frequency raising stage is calculated according to a fitting formula; and the compressor is controlled to conduct the frequency raising operation in the frequency raising speed, specifically, the fitting formula is determined according to the corresponding relationship of the indoor environment temperature and the frequency raising speed of the compressor, and the indoor environment temperature and the frequency raising speed of the compressor are in an inverse relation. 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, the compressor is controlled to conduct the frequency raising operation in the frequency raising speed, and therefore the control method of the air conditioner in the heating mode can improve the universality of the air conditioner and the usage experience of users.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a method for controlling an air conditioner in a heating 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 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...
