Introduction: Interest towards desiccant-based dehumidification systems has recently increased due to their great potential for reduction of both primary energy consumption and greenhouse gas emission with respect to conventional systems. Performances of these devices, in terms of humidity reduction of inlet air, depend on several design and operational parameters. Objectives of this study are the development of a general predictive model of the behaviour of the wheel and the analysis of the performance of the desiccant wheel under various design and operational parameters.
