The cooling performance of air – cooled systems highly depends on ambient air conditions. It is widely known that, the performance of the system decreases when the inlet air temperature increases. This effect especially occurs in summer when the ambient air temperature is high and the cooling load is at its peak value. In order to decrease the inlet air temperature, evaporative cooling can be used. Evaporative coolers can be well combined with air – cooled chillers to decrease the inlet air temperature of condenser. Evaporative cooling is simple and economical way to cool the inlet air since it does not require any mechanical refrigeration and consumes very low power by fan and pump. Therefore combining these two systems can be considered as energy efficient method. As known, evaporative cooling performance strongly depends on the effectiveness of the evaporative cooler. In this study, studies on air cooled chillers with evaporatively cooled condenser have been assessed and the evaporative cooling effectiveness on the performance of air – cooled chillers is investigated.
