ABSTRACT:
An apparatus for dehumidifying air includes a first air path having a first opening, a second opening, and a first desiccant mass intermediate the first and second opening, a second air path, having a first opening, a second opening, and a second desiccant mass intermediate the first and second opening, and an apparatus for causing air selectively from either the first air path or the second air path to flow to an outlet of the apparatus, wherein the ratio of the weight of each of the desiccant masses to the air flow rate into the apparatus outlet is about 1 pound of desiccant for each 10 to 20 cubic feet per minute of air flow. A controller adjusts regeneration heating times based on detected dew point before switching between air paths and detected temperature after switching air paths.
