Abstract

The invention provides a variable frequency air conditioner control method and device, an air conditioner and a storage medium. The variable frequency air conditioner control method comprises the steps that a variable frequency air conditioner is controlled to increase frequency according to a preset frequency increasing mode; and before the frequency of the variable frequency air conditioner reaches the target frequency or within the preset duration after the frequency rising starting moment of the variable frequency air conditioner, the opening degree of an electronic expansion valve of thevariable frequency air conditioner is controlled to be larger than the preset opening degree, and / or the rotating speed of a draught fan in an indoor unit of the variable frequency air conditioner iscontrolled to be larger than the preset rotating speed. The air return temperature can be effectively increased, oil return is optimized, and the oil return performance of the compressor is improved.

Description

technical field

[0001] The present application relates to the technical field of electrical appliances, and in particular to a control method and device for an inverter air conditioner, an air conditioner and a storage medium. Background technique

[0002] With the rapid development of science and technology, air conditioners have gradually become electronic devices commonly used in people's lives, which can provide users with a cool or warm environment.

[0003] When the air conditioner is in the low-temperature cooling mode, it is easily affected by the ambient temperature. If the external ambient temperature is too low, it is easy to cause poor oil return from the compressor and affect lubrication, thereby reducing the performance of the compressor.

[0004] Therefore, how to ensure the oil return performance of the compressor has become an urgent technical problem to be solved. Contents of the invention

[0005] In order to solve the above problems in the prior art, t...
