Abstract
A dehumidifying air handling unit for a heating, ventilation, air conditioning, and refrigeration (HVACR) system includes a housing, a hollow desiccant drum configured to rotate within the housing, and a heat exchanger disposed within the hollow desiccant drum. The hollow desiccant drum includes channels that extend through a sidewall that surrounds an interior space. A desiccant is provided in the channels. The heat exchanger is configured to cool air flowing through the interior space of the hollow desiccant drum. A method of conditioning air includes rotating a hollow desiccant drum within a housing and directing the air to pass through the hollow desiccant drum. The air passing through the hollow desiccant drum includes cooling, with the heat exchanger, the air in an interior space of the hollow desiccant drum, and adsorbing, with a desiccant, moisture from the air cooled by the heat exchanger.
