When moist air passes through the adsorbent of the wheel, water molecules are adsorbed and removed, making the air dry. The processed dry air passes through the condenser, and the water vapor is condensed into water and discharged outside the machine, while the remaining dry air is discharged through the air outlet.

Regenerated air, due to the heat emitted during the desorption process, lowers its own temperature and becomes moist air with high moisture content, which is then discharged outdoors by the regeneration fan. This design greatly improves the dehumidification efficiency of the dehumidifier, while also having a compact structure, providing a huge surface area for sufficient contact between moist air and moisture absorbing media.
