1.Cooling dehumidification

The air is cooled to below the dew point, and then the condensed water is removed.
This method is effective under the condition that the dew point is 8 ~ 10 ℃ or more.

2.Compression dehumidification
Compress and cool the moist air to separate the moisture.
This method is effective when the wind volume is small but not suitable for the conditions of large wind volume.

3. Liquid absorption dehumidification
Lithium chloride solution spray is used to absorb moisture.
The dew point can be reduced to -20 ℃ or so, but the equipment is large, and the absorption liquid must be replaced.

4.Wheel-type desiccant dehumidification
The ceramic fibers of impregnated porous hygroscopic agents are processed into honeycomb-like runners for ventilation.
The dehumidification structure is simple, which can reach -60 ℃ or less through special combination of dew points.
This is the method used by Jierui.
