In evaporative air cooling the outside air is treated with water i.e. the air is made saturated by passing it through water shower or special cooling pads. The dry bulb temp of outside air is brought near to wet bulb temp and thus the air is cooled through adiabatic saturation process.
Air Cooling / Humidification Systems
The cooled air capacity is derived by carrying out sensible heat gain calculations viz –a –viz inside conditions requirement and the air is supplied after passing through filter, washer, eliminator / Cellulose Pads through ducting & Grilles in the department..
