Humidity control in space conditioning has received a good deal of attention in the past twenty or so years. Perhaps the most familiar application is the use of humidifiers in the winter months. Of equal concern is the use of air conditions and dehumidifiers in the summer months. High humidity levels in summer months require lower coil temperatures in order to achieve human comfort levels, and may result in significant product and property damage if humidity levels are not controlled at appropriate level. This study addresses the solid desiccant dehumidifier using IR heaters as an energy efficient desiccant dehumidifier (EEDD). The study is divided into two phases; Phase 1 -- Application assessment; and Phase 2: Prototype design, manufacture, and testing. Phase 1 addresses the total electrical energy usage by all possible applications of the EEDD and evaluates the energy performance of the EEDD in terms of its percentage energy savings compared to the conventional vapor compression cooling and also with the state-of-the-art desiccant dehumidifiers. During Phase 2, a functional EEDD prototype unit was designed and manufactured. The work of Phase 2 was divided into four tasks: Task 1, conceptual design; Task 2, mechanical (blueprint) design; Task 3, manufacture and factory testing; and Task 4, performance testing. 17 refs., 21 figs., 30 tabs.
