Embodiment Construction

[0029] 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 present invention is described in conjunction with the air conditioner operating in cooling mode as an example, this application scenario is not static, and those skilled in the art can also apply the method of the present invention to other application scenarios, such as application and air-conditioning heating mode or dehumidification mode, etc.

[0030] 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 system for controlling ...

Abstract

The invention relates to the technical field of air conditioners, in particular to a control method of an air conditioner. Through the control method, the problems of poor universality and poor user experience existing in an existing air conditioner control method can be solved. The control method comprises the steps that rotation speed of an inner fan is obtained; according to a fitting formula,frequency raising speed of a compressor in the frequency raising stage is calculated; and the compressor is controlled to raise frequency according to the frequency raising speed, wherein the fittingformula is determined according to the corresponding relation between the rotation speed of the inner fan and the frequency raising speed of the compressor. The fitting formula is determined in advance, then the frequency raising speed of the compressor in the frequency raising stage is calculated according to the fitting formula, and then the compressor is controlled to raise the frequency according to the frequency raising speed. Through the control method of the air conditioner, the universality of the air conditioner and use experience of a user can be improved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner control method. 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 cooling / heating and thus bring users a comfortable experience, the existing air conditioners usually increase the frequency of the compressor to a higher frequency ( such as upscaling 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 after the oil return is stable . However, the...
