Energy saving in a split-type air onditioner with evaporative cooling systems

The reduction in the power consumption is very important especially in areas with high temperatures such as Iraq, where the power consumption by the air conditioner is very high. The conventional split-type air conditioner widely used in small and medium size buildings, e.g. residences, offices, and schools. In this work the evaporative cooling unit is designed at the department of Mechanical Engineering of the College of Engineering University of Basrah.. The evaporative cooling unit is connected in front of the condenser to decrease the inlet temperature of the condenser. In addition, their performances depend on the heat transfer between condenser and the ambient airflow. The reduction in the inlet air temperature to the condenser of the air conditioning that leads to reduce the power consumption and enhancement of the coefficient of performance for the refrigeration cycle. The experimental results show: the average power saving is 23%.
