Abstract
An experimental study is conducted to cool the outdoor air using a humidification technique. A wind tunnel was built with a membrane covered tray serves as a test section. An outdoor air passes over a tray full of water and covered with a specific membrane. Air temperatures and relative humidity are measured before and after the tray for several air and water speeds. Air speed is measured at different locations along the centerline of the cross section. Results show that as the angle of the tray increases the air temperature drop increases which improve the efficiency of the humidification technique. This enhancement is reflected by a maximum and minimum temperature drop of 7.52 and 2.41oC respectively. Results also show that as the tray angle increases the air relative humidity increases as expected.
