Embodiment Construction

[0042] 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

[0043] First of all, it needs to be explained that usually air conditioners include an indoor unit and an outdoor unit. Outdoor fan and outdoor heat exchanger, etc. The indoor unit is usually provided with a control system for controlling the work...

Abstract

The invention relates to the technical field of air conditioners, in particular to a control method for an air conditioner in a heating mode, and aims at solving the problems that an existing air conditioner control method is poor in universality and bad in user experience. For the purpose, the control method comprises the steps that outdoor environment temperature is acquired; the valve closing speed of an expansion valve is calculated according to a first fitting formula; the accelerated speed of an outer fan is calculated according to a second fitting formula; the frequency increasing speedof a compressor in the frequency increasing stage is calculated according to a third fitting formula; the expansion valve is controlled to be closed to the target opening degree according to the valve closing speed; the rotation speed of the outer fan is controlled to be increased to the target rotation speed according to the accelerated speed; and preferably, when the expansion valve is closed to the target opening degree and the rotation speed of the outer fan is increased to the target rotation speed, the frequency of the compressor is controlled to be increased according to the frequencyincreasing speed. Through the control method, the control method for the air conditioner in the heating mode has the advantages that the universality of the air conditioner can be improved, and the using experience of users is improved.

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...
