The recent CFC issue regarding the depleting of ozone layer and the greenhouse effect has become an impetus in research and development work for non-CFC air conditioning alternatives. Desiccant cooling is considered a good candidate for replacement of vapor compression chillers. A review of the present status of the desiccant based systems indicate that the technology has significantly advanced in recent years, and has become one of the most promising alternatives. New and better desiccants have been developed and novel cycles and more efficient system designs have been studied. As a result, the thermal coefficient of performance (COP) of desiccant cooling systems has been revised from around 0.6 to 1.0 or higher. These advances coupled with potentially reduced production cost could become very competitive with conventional systems in the near future. This study gives a review of the present status of desiccant materials, system designs, and computer models. 17 refs., 4 figs.
