Abstract
This research described the development of a test setup and performance evaluation of a Multistage Evaporative Desert Cooling System (MEDCS) (Cooling - Humidification - Cooling -Dehumidification) by considering the advantage of indirect evaporative system and overcoming the disadvantages of direct evaporative cooling system using copper tubes and Honey comb cooling pads. In this research the maximum performance in multistage evaporative cooling at 2450 rpm. The best parameters are found at this rpm are temperature 23.6 ℃, relative humidity 63%, specific humidity 0.13 kg of water vapors/kg of dry air, dry bulb temperature 38 ℃, dew point temperature 10 ℃, wet bulb temperature 13 ℃ and enthalpy 75 kJ/kg at average consumption of 8.07 L/h. In multistage evaporative cooling, after reached required relative humidity and specific humidity, by switching off direct evaporative cooling system we can maintain same room temperature by running indirect evaporative cooling technology without any addition of moisture.
