The purpose of this study is to compare different desiccant materials based desiccant wheel for air conditioning applications using a mathematical model. Seven desiccant material wheels are categorized into three groups. The results revealed that the desiccant wheel made of group 2 materials has a higher temperature-difference in comparison to other groups. So, these desiccant wheels cannot be recommended for air-conditioning applications. For higher ranges of process inlet temperature (40 to 50), moisture removal obtained from group 2 wheels is higher than the other wheels and also obtains approximately similar ∆T. But in lower ranges of process inlet temperature (10 to 20), group 3 wheels give higher MR with moderate ∆T. although the temperature difference is higher but, due to the higher moisture removal, group 3 wheels can be the preferable choice.
