Embodiment Construction

[0044] 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 third fitting formula of the frequency-up speed of the compressor in the specific implementation is v y = kT ao +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 third fitting formula can also be v y =k Tao +b(0

[0045] 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 a control method of an air conditioner under a heating mode. The control method of the air conditioner under the heating mode aims to solve the problems that existing control methods of air conditioners have poor universality and bad user experience. In order to realize the purposes, the control method comprises thesteps that the outdoor environment temperature and the outdoor environment humidity are obtained; when the outdoor environment temperature is smaller than or equal to a temperature threshold, the preheating time of an electric heater is calculated according to a first fitting formula; the advanced starting time of an external fan is calculated according to a second fitting formula; the frequencyraising speed of a compressor at a frequency raising stage is calculated according to a third fitting formula; the electric heater and the external fan are controlled to operate; and when the startingtime of the electric heater reaches the preheating time and the operation time of the external fan reaches the advanced starting time, the compressor is controlled to conduct frequency raising according to the frequency raising speed. In this control mode, the control method of the air conditioner under the heating mode can be used for improving the universality of the air conditioner and the useexperience 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...
