How does a chemical adsorbent dehumidifier work?
In this process air from a building’s interior flows over the desiccant material. It attracts moisture. The desiccant material is simultaneously dried by air flowing the other way that exhausts the moisture to the outside of the building. This describes the most common form, cyclical chemical adsorbent dehumidifiers. A wheel cycles the desiccant material. On one side of the wheel, material takes moisture out of the air. On the other end, material is dried by air flow that removes the moisture to the outside air. Non-cyclical chemical adsorbent dehumidifiers are a variation that is not as common. In this process, the chemical adsorbent material is contained on a bed. Two different air streams, low humidity and high humidity, are passed through sealed chamber sections (without mixing the high humidity and low humidity air streams). The desiccant material may be removed and dried at intervals. One of the downfalls of a chemically adsorbent dehumidifier and its desiccant material is that t
