An efficient gas-fueled cooling system based on the concept of desiccant dehumidification is under development. Performance maps of the system can be generated through the use of a computer-simulation model, which predicts not only system performance but also that of the desiccant wheel. The performance of the desiccant wheel is dependent on several factors including the desiccant used, substrate material, and channel size and geometry. Each of these factors affects the ability of a desiccant to adsorb or absorb water from moist air, and then to desorb the water when the desiccant is regenerated. A laboratory facility was constructed for the purpose of testing subscale desiccant wheel samples furnished by several manufacturers. Wheel samples were exposed to a series of time-dependent dehumidifying and regeneration tests. Data from these tests were used to evaluate and compare performance from several wheel samples, including lithium chloride, silica gel, molecular sieves, and activated carbon.
