Performance Comparison of Different Desiccant Material Based Wheels for Air Conditioning Application

Abstract

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°C), moisture removal obtained from group 2 wheels is higher than the other wheels and also obtains approximately similar ΔT. But in lower ranges of process inlet temperature (10 to 20°C), group 3 wheels give higher MR with moderate ΔT. although the temperature difference is higher but, due to the higher moisture removal, group 3 wheels can be the preferable choice.
