For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1, fig. 1 is a schematic flow chart of an air conditioner humidification control method provided by the present invention, where the air conditioner humidification control method includes:
s101: acquiring the moisture content of return air, setting the moisture content of the return air and the moisture content of blowing water of the air supply;
specifically, in view of the technical problems in the background art, in combination with consideration of the actual humidification requirement of the air conditioner and the return air moisture content, the preset ideal air moisture content and the supply air moisture content of the air conditioner, the return air moisture content, the set moisture content and the supply air moisture content are obtained in this step, so that the return air moisture content, the set moisture content and the supply air moisture content are used as the data basis of the subsequent steps to determine the required humidification quantity. The air return moisture content refers to the actual moisture content of air at an air return opening of the air conditioner, the set moisture content refers to the ideal moisture content of air at the air return opening of the air conditioner, and the air supply and water blowing moisture content is a moisture content threshold value of air supply and water blowing of the air conditioner under the current running environment, namely the moisture content threshold value of air at the air supply opening of the air conditioner under the current running environment.
Specifically, the step can be implemented by collecting designated return air parameters, setting parameters and air supply parameters, calculating the return air moisture content according to the return air parameters, calculating the setting moisture content according to the setting parameters, and calculating the air supply and water blowing moisture content according to the air supply parameters.

specifically, the required humidification amount refers to the air conditioner humidification amount from the current ambient humidity to the target ambient humidity, and can be obtained by calculating the difference between the return air humidity amount and the target humidity amount. Because the moisture content of the air-sending and water-blowing is larger than the set moisture content, the air-sending and water-blowing cannot be caused due to the fact that the set moisture content is taken as the target moisture content for humidification at the moment, the required moisture content is determined to be the difference between the return air moisture content and the set moisture content in the step, so that the return air moisture content reaches the set moisture content as soon as possible, and the humidification requirement is met.
S104: determining the required humidification amount as the difference between the return air moisture content and the blowing air moisture content;
specifically, since the moisture content of the air-sending and blowing water is not greater than the set moisture content, it is considered that if the set moisture content is used for humidification, the air content at the air-sending port may be higher than the moisture content of the air-sending and blowing water, so that the air-sending and blowing water is caused.
S105: and controlling the air conditioner to humidify according to the required humidification amount.
Specifically, according to the determined demand humidification volume, the air conditioner is controlled to humidify, and the problems that the safety is influenced by blowing and water blowing caused by blowing are avoided as the air after humidification can be guaranteed to reach the set humidity demand.
The steps in the embodiment of the invention can be applied to the main controller of the air conditioner.
