What is evaporative air cooling, how does it work and how effective is it?

Evaporative air cooling is a naturally occurring phenomenon. When air and water come into contact the water evaporates into the surrounding air, reducing its temperature. This is why on a hot day it is cooler near a lake, waterfall or fountain.

Evaporative cooling is the oldest known method of cooling. The ancient Egyptians used it to reduce the temperature inside their buildings. They placed water saturated cloth sacks in windows and doors, as warm air entered; it passed through the sacks and was cooled.
