Air conditioner control method in heating mode

Abstract

The invention relates to the technical field of air conditioners, in particular to an air conditioner control method in a heating mode. Through the air conditioner control method in the heating mode,the problems of poor universality and poor user experience existing in an existing air conditioner control method can be solved. The air conditioner control method comprises the steps that the outdoorenvironment temperature is obtained; when the outdoor environment temperature is smaller than or equal to the temperature threshold, preheating time of an electric heater is calculated according to afirst fitting formula; according to a second fitting formula, frequency raising speed of a compressor in the frequency raising stage is calculated; the electric heater is controlled to preheat the compressor according to the preheating time; and preferably, when the starting time of the electric heater reaches the preheating time, the compressor is controlled to raise frequency according to the frequency raising speed. Through the control mode, the air conditioner control method in the heating mode can improve universality and heating efficiency of an air conditioner and improve use experience of a user.

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...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the above-mentioned problems in the prior art, that is, in order to solve the problems of poor universality and poor user experience existing in the existing air-conditioning control methods, the present invention provides a control method of the air-conditioning in the heating mode. The air conditioner includes a compressor, an expansion valve and an electric heater, the compressor is equipped with an electric heater, and the control method includes:
