A Study on the Performance of a Solar Desiccant Cooling System by TRNSYS in Warm and Humid Climatic Zone of IRAN

Abstract

Increase in air humidity leads to discomfort and can cause health problems. Nowadays, traditional vapour compression air conditioning systems are widely used to decrease the moisture content of the air, but they result in high electricity bills. Recent studies show that use of absorbent material in the conventional systems can reduce electrical energy consumption. The desiccant systems are reasonably-priced, produce no CFCs, and capable of both drying and filtering the air. They provide an opportunity to control humidity and temperature independently, and have the capability of using low quality thermal energy. The aim of this study is to determine the performance of a Solar Desiccant Cooling System by TRNSYS in warm and humid climatic zone of IRAN. This paper computed the performance of a simple desiccant evaporative cooling cycle in four selected cities in Warm and Humid climatic zone of IRAN (i.e. Kish, Bandarabbas, Bushehr and Gheshm). The coefficient of performance (COP) has been computed for each location and compared. The results show that for Kish, this system shows high potential for comfort cooling in buildings compared to other locations in the same climatic zone.
