A Technical Review of Available Desiccant Design Techniques

Abstract

Abstract Desiccant wheel system is a topic of research because of increased requirement in HVAC industry and in dehumidification industry. In HVAC industry desiccant cooling system operating on regenerating heat supply from renewable source as solar are making their impact and desiccant wheel plays important role as main part in dehumidification industry. It’s been approximately two decades since the desiccant wheel has made around in market for large level. Many designs and technologies are already available for desiccant wheels and some are available within the research and experiments only. This article provides a better understanding of available research and designs for desiccant wheel systems. Review for difference of liquid and solid desiccants operated cooling systems, various regenerating technologies used for desiccant different desiccant material and different materials for subtract of desiccant wheel, different construction design in terms of number of sectors and direction of air flowing in the desiccant sections prepared and discussed here. Apart from this various simulation models of desiccant systems studied based on mathematical models are studied here. Based on these reviews an effective conclusion is given for desiccant operated systems. At the end of the review future possibilities for advancement in desiccant industries are mentioned.
