How does a rotary dehumidifier do dehumidification work in a low temperature environment

The reason for using a rotary dehumidifier in a low humidity environment is based on the principle that other dehumidification methods are different from rotary dehumidification methods. All other dehumidification methods except the wheel dehumidification are limited by their own dew point temperature and cannot reduce the air temperature to achieve the low dew point conditions required for low humidity. So how should the rotary dehumidifier do its dehumidification work in a low temperature environment? Next, let the editor of the rotary dehumidifier explain this, I hope it can be helpful to everyone, the specific content is as follows:

1. Cooling and dehumidification: Cool the air below the dew point, and then remove the condensed moisture. Effective when the dew point is above 4°C.

2. Compression and dehumidification: cooling and compressing the humid air quality to separate moisture. Effective for small air volume, but not suitable for large air volume.

3. Adsorption and dehumidification on the solid surface: use these capillary interactions to adsorb moisture onto the solid desiccant. The dew point can be lowered, but the larger the adsorption area, the larger the equipment.

4. Liquid absorption and dehumidification: spraying lithium chloride aqueous solution to absorb water. The dew point can be reduced to about 0°C, but the equipment is large and needs to be replaced as an absorbent.

5. Chute dehumidification: Process the sheet soaked with desiccant into a honeycomb chute for ventilation. Simple structure, dehumidification specifications

The above five points are all about the dehumidification work that the rotary dehumidifier should do in a low temperature environment. Thank you for your understanding and support!
