Given the escalating water crisis and impending climate change, the sustainability of evaporative cooling systems, particularly direct evapo-rative coolers, has become a pressing concern in Iran, one of the world's largest consumers of this technology. This study aimed to inves-tigate the impact of saturation efficiency and capacity on water con-sumption in particularly direct evaporative coolers under the specific climatic conditions of Qom, Iran. A thermodynamic model was devel-oped to simulate the performance of these systems, and its results were validated against experimental data. The modeling results indicated a direct correlation between saturation efficiency, airflow rate, and water consumption. Specifically, increasing the saturation efficiency from 40% to 90% in a 5000 CFM air conditioner led to a 131% increase in water consumption. Moreover, larger capacity units consumed signifi-cantly more water. For instance, a 7000 CFM cellular pad cooler con-sumed roughly twice as much water as a 3500 CFM unit. Conversely, while conventional pad coolers with lower saturation efficiencies con-sumed less water, they also resulted in higher discharge air tempera-tures. These findings underscore the trade-off between improved cool-ing performance and increased water consumption in high-efficiency evaporative cooling systems. Consequently, to optimize water use in residential settings, there is a pressing need for policies that promote more efficient cooling technologies and reduce reliance on water-cooled air conditioners.
