Evaporative cooling towers are useful for cooling buildings and outdoor areas in hot and dry climates. Evaporative cooling towers work by allowing water to evaporate, either by using evaporative cooling pads or by spraying water. Incoming air cools down by evaporation, causing a downdraft of cool air that will reduce the temperature inside the building. The performance of the evaporative cooling device depends outdoor humidity, the tower height and cross section, as well as the amount of water being evaporated. These cool towers can also be used to cool exterior spaces.
