Comparative study of different desiccant wheel designs
Applied Thermal Engineering, 2011Desiccant/evaporative cooling systems offer an environmentally benign alternative to conventional vapor compression chillers. A desiccant wheel is the heart of this heat driven cooling system and it uses a solid desiccant for dehumidification with silica gel being the most widely used.

Performances of the Hybrid Active Desiccant Wheel System with Type III Desiccant
Applied Mechanics and Materials, 2010A new type of hybrid desiccant air conditioning system combining an active desiccant wheel with a conventional front-positioned cooling coil is presented, in which Type Ⅲ desiccant is used in the active desiccant wheel. Then a preliminary experiment is carried out in order to investigate the feasibility of the hybrid desiccant system serving as a ...

Applied Thermal Engineering, 2010
Abstract A mathematical model for predicting the performance of novel silica gel haloid compound desiccant wheel is established. Both the gas side resistance and the solid side resistance are considered in the model. It is found that the results of this model agree better to the experiments than the results of a former model which does not take the ...

Modeling and Analysis of Desiccant Wheel
2016Desiccant cooling systems have advantages in environmentally friendly operation and separate control of sensible and latent cooling loads, which leads to comfortable indoor air quality. In addition, the desiccant cooling system is a heat-driven cycle and therefore has the ability to use low-grade energy.

Experimental investigations on thin polymer desiccant wheel performance
International Journal of Refrigeration, 2014Abstract In this study, the performance of a new polymer desiccant wheel (DW), which can be used for dehumidification in a solid desiccant cooling system, was investigated. In order to investigate the compact design of the DW for compact cooling system, DWs were evaluated at four levels of thickness while varying the inlet air temperature, humidity ...
