Project Objective

PARC, in partnership with Daikin U.S. Corp. and Oak Ridge National Lab (ORNL), aims to drastically reduce the energy demand for latent heat removal in air cooling by developing a new approach to dehumidification using an electrically regenerated liquid desiccant. PARC’s technology uses up to 30 times less energy to regenerate desiccants compared to existing thermal technologies.  It is a quiet system with the capability to both reduce peak load, and to shift the remaining air-conditioning load to a more desirable time.

Project Impact

PARC will develop a highly efficient dehumidification system. If implemented at scale, PARC’s invention would enable total commercial AC loads to be reduced by >60% in ASHRAE climate zones 1A-6A leading to 0.45 Quads of annual energy savings by 2030.
