A novel low-temperature desiccant dehumidification system has been demonstrated and evaluated at a supermarket field test site in New Jersey. Unlike traditional desiccant dehumidification systems that use high regeneration temperatures (220--280 F), this system uses low-temperature (130--150 F) waste heat energy from vapor compression refrigeration condensers to regenerate a recently-developed desiccant material. The 7000 cfm (3300 L/s) unit has a latent capacity of approximately 80,000 Btuh (23.5 kWt) with fan energy as the only purchased energy source. This report presents and discusses the performance of the desiccant system under field conditions and its interactions with the refrigeration and conventional HVAC systems. Results indicate that the system performed well in the field with no deleterious effect on refrigeration system operations.
