Two Stage Air Cooler

The combination of direct evaporative cooling and indirect evaporative cooling system is called indirect-direct two stage evaporative cooling. In two stage air cooler Effective temperature decreases, COP increases up to 13 which are significantly higher than normal cooler and conventional air conditioner, Refrigeration effect increases, Makeup water recharges time increases for the same configuration has been obtained, Specific humidity increase is significantly lower than that of in case of direct cooling system. Two stage air cooler is energy effective, eco friendly, cost effective cooling system and with some further modification it may be hope as replacement of air conditioner.
