Embodiment Construction

[0039] Preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention, and are not intended to limit the protection scope of the present invention. For example, although the second fitting formula of the frequency-up speed of the compressor in the specific implementation is v y = kTao +b is shown as an example, but the form of this fitting formula is not static, and those skilled in the art can adjust it according to needs, so as to adapt to specific applications. For example, the second fitting formula can also be v y =k Tao +b(0

[0040] First of all, it needs to be explained that generally air conditioners include indoor units and outdoor units. The indoor units are equipped with indoor heat exchangers and indoor fans. , The compressor is equipped with an electric heater (s...

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...
