Problems solved by technology

At this time, freezing problems such as frosting and icing of the internal unit are prone to occur.
As a result, the dehumidification effect is poor. If the frost layer or ice layer is too thick, it will cause water leakage from the internal unit, which seriously affects the user experience.

Abstract

The invention provides an air conditioner control method and device, an air conditioner and a readable storage medium. The air conditioner control method comprises the steps of obtaining the environment temperature value of an outdoor unit of the air conditioner; judging whether the environment temperature value meets an anti-freezing dehumidification control condition or not; and performing anti-freezing dehumidification control if it is judged that the anti-freezing dehumidification control condition is met. The anti-freezing dehumidification control comprises the steps of obtaining the temperature value of an evaporator; and regulating the valve step value of a target electronic expansion valve of the air conditioner according to the temperature value of the evaporator, and regulating the speed value of an outer fan of the air conditioner so as to maintain the temperature of an evaporator coil. According to the air conditioner control method provided by the embodiment of the invention, the freezing problems of frosting, freezing and the like of an indoor unit during dehumidification control of the air conditioner are solved.

Description

technical field [0001] The present invention relates to the technical field of air conditioner control, in particular to an air conditioner control method, an air conditioner control device, an air conditioner and a readable storage medium. Background technique [0002] At present, the existing air conditioners all have a dehumidification function. The usual way is: after the air conditioner turns on the dehumidification function, the air conditioner starts to refrigerate, and lowers the speed of the internal unit to reduce the temperature of the evaporator; When the temperature is lower than the dew point temperature of the humid air, the air conditioner starts to dehumidify. [0003] In reality, air conditioners often use the dehumidification function in relatively humid seasons. For example, in the rainy season, the indoor and outdoor ambient temperature is not high at this time, generally around 20°C; coupled with the poor heat transfer inside the air conditioner, the t...
