A novel all-electric desiccant dehumidifying system was demonstrated and evaluated at a supermarket field test site in New Jersey during 1995. Unlike traditional desiccant systems, this system uses waste heat from vapor-compression refrigerating condensers to regenerate a recently developed desiccant material. The 7,000-cfm (3,300-L/s) unit has a latent capacity of approximately 7 tons (25 kW), with fan energy as the only purchased energy source. This paper discusses the performance of the desiccant system under field conditions and its interactions with the refrigerating and conventional heating, ventilating, and air-conditioning (HVAC) systems. Results indicate that the system is three to four times more efficient for moisture removal than a conventional HVAC system with no deleterious effects on refrigerating system operations.
