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:
- integrated active desiccant rooftop (IADR) air conditioners,
- liquid desiccant heat pumps,
- active desiccant dehumidification modules,
- Cromer cycle desiccant dehumidification rooftop systems, and
- indoor air quality (IAQ) and the removal of air pollutants and improved building ventilation using desiccant dehumidification.
