How Active Dehumidification Works
by Peter Yost
Dehumidification, sometimes abbreviated as DEH or DH, removes water from indoor air.
Active dehumidification is mechanical moisture removal intended to maintain comfort and protect building materials.
There are two primary ways to actively dehumidify: by condensing moisture using a heat pump—refrigerant-based DEH—and by adsorbing moisture using a desiccant wheel—desiccant DEH. (We use the less-familiar term adsorption to describe how water molecules adhere to the surface of a material; absorption, in contrast, occurs uniformly throughout a material.)
