| Abstract | ||||
| Direct evaporative coolers are widely used in very hot and dry climate such as Aswan city. The accepted reduction of temperature and the value of relative humidity inside the buildings is an interesting topic. Experiments were made to measure the reduction of the room temperature due to the cooled air exiting from a direct evaporative cooler. All experiments are made during an ambient relative humidity less than 20% and the room was maintained at the same volume and heat load. The instant room temperatures were measured during the time until the steady state at different flow rates of cooled air and different very hot ambient temperatures. The experimental results were used to determine an empirical equation capable to predict the reduction of the room temperature at different ambient temperatures during very dry climate. | ||||
