Modeling of Indirect Evaporative Air Cooler for Thermal Performance Study

This paper presents a review, calculations and measurements based study on the parts of Indirect Evaporative Cooling (IEC) stand device, which have an influence on thermal performance. The study was undertaken considering a variety of aspects including background, history, current status, and concept. Parts of experimental stand device have been described as equations of heat and mass transfer in primary and secondary air and water flows. The model has been validated with self-made device measurements in the laboratory. The main goal has been to make a working stand device for future research of IEAC device cooling efficiency, which mostly depends on mass flow rates of primary and secondary air flows and spacing between the plates of wet and dry passages
