Abstract: This research presents the experimental investigation of an indirect evaporative cooling system in Iraqi climate, this system aims to cool the outside fresh air by water evaporation without increasing in moisture content of the evaporative cooled which is one of the most important disadvantages of the traditional evaporative air coolers. The system composing from the sensible heat exchanger that cools the outside fresh air associated with the evaporative cooling tower. Part of produced cold air extracted to the cooling tower allowing the cooling tower allowing the cooling tower to produce cold water at temperatures less than the system inlet wet bulb temperature. The results of the system show the capability to provide a reduction in energy consumption up to 40% in comparison with mechanical vapor compression systems. The system COP and effectiveness reached 8.82 and 0.768, respectively. Also, the cooling system provides 19.5 at 35°C system inlet temperature. On depending on the testing results, this system can reduce the gap between evaporative air cooling systems and mechanical vapor compression systems as an environmentally clean and energy efficient system.
