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 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 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. Wait. The indoor unit is usually provided with a cont...

Abstract

The invention relates to the technical field of air conditioners, in particular to an air conditioner control method in a heating mode. The air conditioner control method in the heating mode aims to solve the problems of poor universality and poor user experience of an existing air conditioner control method. The control method includes the steps that an outdoor ambient temperature is obtained; anaccelerated speed of an external fan is calculated according to a first fitting formula; a frequency ascending speed of a compressor in a frequency ascending stage is calculated according to a secondfitting formula; the external fan is controlled to accelerate to a target rotational speed according to the accelerated speed; and preferably, the compressor is controlled to perform frequency ascending according to the frequency ascending speed while the external fan accelerates to the target rotational speed according to the accelerated speed. According to the control mode, the air conditionercontrol method in the heating mode can improve the universality of the air conditioner and improve the 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...
