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 = kT in +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 / Tin +b etc.

[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. Wait. The indoor unit is usually provided with a control sys...

Abstract

The invention relates to the technical field of air conditioning, in particular to a control method of an air conditioner in a heating mode. The control method aims at solving the problems of poor universality and poor user experience of an existing air conditioning control method. The control method comprises the steps that indoor ambient temperature is acquired; the acceleration of an external fan is calculated according to a first fitting formula; the frequency raising speed of a compressor in the frequency raising stage is calculated according to a second fitting formula; the external fanis controlled to speed up to the target rotation speed according to the acceleration; and when, or before or after the external fan accelerates to the target speed according to the acceleration, the compressor is controlled to carry out frequency raising according to the frequency raising speed. Through the control mode, the control method of the air conditioner in the heating mode can improve theuniversality of the air conditioner, and improve the user experience.

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...
