The Use of Desiccant Cooling System with IEC and DEC in Hot-Humid Climates
Full Paper(PDF, 395KB)
Abstract:
Indoor moist surroundings affect air cleanliness and thermal comfort when relative humidity is above 70%, which may lead to condensation within the building structure and on interior and exterior surfaces and subsequent development mould and fungi. Moreover, the humidity issue is a major contributor to energy inefficiency in HVAC devices. The objective of this study was to investigate the feasibility to apply the desiccant cooling system in hot-humid climate for interior thermal comfort purpose. Using measured data sets, validation of TRNSYS basic model was undertaken. Two models of cooling system using Indirect Evaporative Cooling (IEC) and Direct Evaporative Cooling (DEC) were simulated for different climatic conditions. The result shows that the desiccant cooling system with IEC and DEC can be a suitable solution for thermal comfort in buildings in hot-humid climate.
