Abstract: Conventional air conditioners work based on vapor compression cycle. They draw a lot of power for their operation. This paper emphasizes a new technique which is to precool the air that enters into a conventional air conditioner using eco-friendly evaporative cooling effect. Conventional air conditioners are generally designed to recirculate 60% of indoor air and mix it with 40% of atmospheric air before passing the mixture over the evaporator coil. The process is here is to precool the atmospheric air that mixes with the recirculated air using a heat exchanger coupled with an evaporative cooler. By precooling the atmospheric air at the air intake the power consumed by the air conditioner can be reduced significantly. This will increase the overall Coefficient of Performance of the air conditioning system. Thus power to run air conditioners is saved with the effective cooling in an eco-friendly manner
