Description
Technical Field
The invention relates to the technical field of air conditioners, in particular to a method and a device for dual control of temperature and humidity of an air conditioner, a storage medium and the air conditioner.
Background
The control method of the existing household variable frequency air conditioner mainly takes temperature as a controlled parameter. When the air conditioner operates in a refrigerating mode, due to the fact that two processes of cooling and dehumidifying exist when air flows through the evaporator, the temperature of the air conditioning room is controlled singly, and the influence of humidity on human comfort is ignored. According to the literature, under the same room temperature, such as 26 ℃, as the relative humidity of the room increases, the human body heat sensation is enhanced, and the comfort level is reduced. Especially for the high-temperature and high-humidity south China and south China in summer, the air conditioner takes the temperature as a controlled parameter, the room humidity is high when the set temperature is high, the human body comfort is poor, and in order to meet the cooling requirement, a plurality of users reduce the set temperature, so that the room dehumidification capacity is increased, and the power consumption is increased.
For the problem of humidity control of an air-conditioned room, most of control schemes proposed in the prior art calculate moisture content according to temperature and humidity, judge whether dehumidification or moisture retention is needed, perform dehumidification by adjusting wind speed, and perform moisture retention by adjusting operating frequency of a compressor. These control schemes still have the problems of poor efficiency and poor comfort in actual control.
