Desiccant Dehumidification: Integrated Active Desiccant Rooftop (IADR), Desiccant Compression Systems, and Indoor Air Quality (IAQ)

Desiccant dehumidification employs chemical compounds that have an affinity for water vapor. Water vapor in the air coming in contacct with the desiccant material is adsorbed onto the surface of the desiccant reducing the absolute humidity of the surrounding air. Thermal energy is required to desorb the water so the desiccant can be reused. This can be produced by a natural gas burner or from recovered waste heat from an electric generator. The Department of Energy (DOE) has funded work on:
