A desiccant system keeps humidity low by drying the incoming fresh air, so air conditioning equipment does not have to be oversized and operating costs can stay low while meeting modern bulding codes. Those problems are caused by excess moisture in air pulled into the building by air conditioning units and toilet fans. A desiccant system provides dry fresh air so moisture cannot accumulate inside the building, avoiding the familiar but unpleasant musty odor typical of hotels infested with mold and mildew. Facilities Older, sedentary people suffer in cool, humid buildings. But high humidity is often a consequence of the high ventilation rates needed to provide adequate fresh air in high-density residential spaces.
Desiccant systems dry the incoming fresh air, which keeps humidity low inside the building.
At low humidity, the temperature can be set higher for resident comfort without making the more active, hard working staff uncomfortable.
