Abstract

In this study, the evaporative cooler is developed by adding multistage of heat
exchangers (air – air and water – air) to cool indirectly and indirectly the input air and then
cooling directly inside the classical evaporative cooler. The multistage evaporative cooler is
assisted to reduce the energy consumption, environmental pollution, global warming
phenomenon and manufacturing cost compared than compression refrigeration systems. The
multistage evaporative cooler is suitable and done in houses and large buildings with relatively
high temperatures and humidity. The experimental results of developed evaporative cooler
showed that adding cooling stage to classical cooler reduces the out dry bulb temperature about
(50%) and the specific humidity by (70%).
