Abstract

Desiccant cooling is an environment friendly alternative system against conventional vapor compression system. In this system Desiccant wheel is a heart in which dehumidification takes place by means of Desiccant hygroscopic substance.  Appropriate design of Desiccant wheel is necessary to fulfill the requirement of this system to make it efficient. This paper shows a review of different mathematical modeling for prognosticating the performance of Desiccant wheel by considering Convective Energy and Mass transfer and some parameters like Humidity Ratio, Temperature, Channel geometry etc. Comparative analysis with Result and some issues is discussed in this paper.
