Humidification control method and device

Abstract

The invention provides a humidification control method and device. The method includes the steps of obtaining an environmental humidity value and a target humidity value; according to the difference value between the environmental humidity value and the target humidity value, determining an opening degree value of a humidification valve; according to the determined opening degree value, controlling the opening degree of the humidification valve. According to the scheme above, the humidification control precision can be increased, a better experience effect of an air-conditioning humidificationfunction can be provided for users, and meanwhile, ponding phenomena caused by humidification on an air conditioner can be substantively reduced.

Description

technical field [0001] The present invention relates to the technical field of equipment control, in particular to a humidification control method and device. Background technique [0002] At present, the humidification valve of the air-conditioning humidification function generally controls the opening and closing of the humidification valve by powering on and off the relay, that is, the existing humidifying valve only has two states of open and closed, and its opening cannot be adjusted. [0003] It is precisely because there are only two states of on and off, so when the humidification valve is opened, the flow of pure water flowing through the humidification valve is fixed. On the one hand, when the wind speed of the fan is not enough, the water mist from the nozzle cannot exist. It is completely blown out of the air conditioner, which leads to problems such as water accumulation in the air conditioner when the humidification is turned on. On the other hand, when the amb...

Problems solved by technology

[0002] At present, the humidification valve with the humidification function of the air conditioner generally controls the opening and closing of the humidification valve by the power on and off of the relay, that is, the existing humidification valve only has two states of open and closed, and its opening cannot be adjusted.

[0003] It is precisely because there are only two states of on and off, so when the humidification valve is opened, the flow of pure water flowing through the humidification valve is fixed. On the one hand, when the wind speed of the fan is not enough, the water mist from the nozzle cannot exist. It is completely blown out of the air conditioner, which leads to problems such as water accumulation in the air conditioner when the humidification is turned on. On the other hand, when the ambient humidity value is close to the target set humidity value, because the water flow of the humidification valve cannot be adjusted, there is ambient humidity. Value overshoot phenomenon, which reduces the comfort of the user experience of air conditioning humidification, etc.

[0004] For the above problems, no effective solution has been proposed
