Activated alumina, Desiccant clay, and Silica gel are arranged as single-layer desiccant beds. Experiments have been conducted under warm and humid climate conditions and for various Reynolds numbers between 5300 and 18600. Activated alumina, Silica gel, and Desiccant clay show 5.4, 4.6, and 3.4 times higher adsorption coefficients at Reynolds number 18,600 than at Reynolds number 5,300. The adsorption coefficient is inversely proportional to time and Reynolds number irrespective of climate conditions and desiccant materials. Silica gel adsorbed the highest humidity under warm, humid climate conditions compared to Activated alumina and Desiccant clay. However, Desiccant clay is the most energy-efficient moisture adsorption material for Reynolds numbers lower than 12000, and the contrary is applicable for Silica gel. Silica gels’ pressure drop is, on average, 29.6% and 51.9% higher than Activated alumina and Desiccant clay. Full Text Additional Declarations No competing interests reported.
