“…Several investigations have been carried out by different researchers to improve the performance of the EC system. The major factors that significantly affect the performance of the EC system are air flow rate, condition of ambient air like dry bulb temperature, humidity, etc., the water flow rate through the cooling pads, thickness, density, and material of cooling pads [8,9,10,11,12,13]. The selection of the wet media pad material depends on many factors such as safety, cost, availability, effectiveness, and application [14].…”
