Characterization of desiccant wheels with alternative materials at low regeneration temperatures / Stephen D. White in International journal of refrigeration, Vol. 34 N° 8 (Décembre 2011) 

Public ISBD [article]  in International journal of refrigeration > Vol. 34 N° 8 (Décembre 2011) . - pp. 1786–1791 Titre : Characterization of desiccant wheels with alternative materials at low regeneration temperatures Titre original : Caractérisation des roues déshydratantes utilisant des matériaux innovants à des basses températures de régénération Type de document : texte imprimé Auteurs : Stephen D. White, Auteur ; Mark Goldsworthy, Auteur ; Roger Reece, Auteur Année de publication : 2012 Article en page(s) : pp. 1786–1791 Note générale : Génie mécanique Langues : Anglais (eng) Mots-clés : Desiccant  wheel  Dehumidification  Silica  gel  Polymer  Zeolite Résumé : A number of new desiccant materials have been proposed which have the potential to improve the performance of desiccant wheels being regenerated at low temperature. Desiccant wheels containing two such desiccant materials (zeolite and superadsorbent polymer) were compared with a conventional silica gel desiccant wheel. The superadsorbent polymer desiccant wheel achieved greater dehumidification than the silica gel wheel when dehumidifying high relative humidity air with low temperature (50 °C) regeneration air. The temperature of dehumidified air exiting the polymer wheel was also lower. The zeolite desiccant wheel was generally less effective at dehumidifying air and had a higher pressure drop.
