The study trying to explain and utilize the adiabatic cooling principle in the chillers of high capacity in dry and hot environment. This methodology system designed to enhance the efficiency of cooling equipment by exploiting the principles of evaporative cooling. During the hot weather months units are under constant pressure to circulate enough cool air to the area where it is needed. but simply when air temperature increases, electricity consumption in air-conditioning units increases substantially and in addition to this process the cooling capacity of the air conditioning unit will decrease. The study aims to renovate the traditional refrigeration system, so that it can be developed to take advantage of the adiabatic evaporative cooling process without complicated changes neither a completely demolishing.
