Moisture Absorber is also called desiccant and desiccant. In theory, any substance that can absorb moisture from the air can be called a hygroscopic agent. According to the state of the hygroscopic agent, it can be divided into solid, liquid and gas. Three different types of dehumidifiers work on the following principles:

1. Solid Moisture Absorber: adsorption principle

Solid Moisture Absorber is generally a porous substance with a large surface area, which can absorb moisture in the air under surface adsorption and capillary condensation. Since the partial pressure of water vapor on the surface of the solid hygroscopic agent is lower than the partial pressure of water vapor in the air, it can be used to absorb moisture in the air to achieve the purpose of air dehumidification.

2. Liquid Moisture Absorber: absorption principle

Liquid Moisture Absorber has strong moisture absorption and moisture capacity, and can directly treat air. When the liquid moisture absorbent is in direct contact with humid air, the driving force is the difference between the partial pressure of water vapor in the air and the saturated vapor pressure on the surface of the liquid moisture absorbent. , so as to achieve the effect of air dehumidification.

3. Gas Moisture Absorber: Dilution Principle

The working principle of gas Moisture Absorber is to use two kinds of air with different humidity (dry air and humid air) to mix and undergo heat and mass exchange, so as to achieve the effect of humid air dilution and dehumidification.
