Abstract

The invention belongs to the technical field of air conditioner control and particularly relates to a method and a system for controlling humidity of an air conditioner. According to the method and the system, even if the air conditioner is in a low-frequency operation refrigeration state such as an energy-saving mode, the rotation speed of an indoor unit can be adjusted repeatedly through a preset evaporator temperature critical value, and the fan rotation speed is further adjusted to keep the evaporator temperature constant to achieve dehumidification, accordingly, an effective dehumidification function is guaranteed, the dehumidification step is quit automatically when the humidity value is below a user set humidity value, energy is saved, the environment is protected, and the experience and the comfort level of users are improved.

Description

technical field

[0001] The invention belongs to the technical field of air conditioner control, and in particular relates to an air conditioner humidity control method and control system. Background technique

[0002] From the perspective of human comfort index, temperature and humidity are two important factors. In southern my country and coastal areas, the temperature is suitable but the humidity is high. For example, in the rainy season in the south of the Yangtze River, the indoor air temperature can be maintained at 25 -28 degrees is a relatively comfortable temperature for the human body, while the relative humidity outside is basically maintained at 70%, and there are even cases where the humidity reaches 90%, which makes people feel humid and hot.

[0003] In the prior art, when the air conditioner uses the cooling mode (whether it is manual cooling mode, automatic cooling mode or energy-saving cooling mode), the frequency of the air conditioner starting to run is hig...
