Evaporative cooling or simply put, cooling with water is a natural occurrence and is the oldest known method of transforming hot summer air into fresh moist cool air to cool indoor living areas. Archaeologists have found proof that the mechanism usage dates back to ancient Egyptian days where people hung wet materials to allow wind to blow through them to create a cooling effect. The feeling is similar to the cool refreshing sensation that you would feel when you immediately step out of a swimming pool, when the water quickly evaporates from the body and takes away the heat with it.Evaporative air cooling systems use the natural process of water evaporation and an air-moving system to cool air and are a superb alternative to air conditioning systems. Using large cooling pads, a water distribution system and centrifugal/axial/exhaust fan, hot air is drawn from outside and passed through wet cooling pads. The air is then chilled by evaporation and disseminated through a ducting network to cool the complete area.
