Background

Because of the comfort of indoor human bodies or the requirements of production processes, the air conditioning system often needs to humidify the air, and the moisture content of the air is increased by supplementing water vapor into the air, so that the indoor relative humidity control requirement is met. According to the operation characteristics of the central air conditioning system, the selection of a humidifying mode is critical under the conditions of meeting environmental indexes and requiring energy conservation. Four humidification modes are most commonly used in air conditioning systems: dry steam humidification, wet film humidification, high pressure micro mist humidification and steam-water mixed cold mist humidification.

Wet film humidifiers commonly suffer from several drawbacks: 1) The wet film is small in wind resistance, so that the wet film material is not dense, when the wet film is installed in an air conditioning unit, the section flow velocity of air flowing through the wet film humidifier is about 2.5-3 m/s, and the air flow velocity is higher by considering the aperture ratio of a porous medium, so that a serious water flying problem can be generated; 2) Due to the generation of the flying water, when the direct drainage water supplementing mode is used, water distributed at the top of the wet film and vertically permeated downwards can be taken away, the lower wet film material can not be wetted, and the humidifying efficiency of the wet film humidifier can be lowered.
