Evaporative cooling is the oldest form of air conditioning ever used

The ancient Greeks used to fill terracotta pots full of water and leave them by doors and windows to benefit from evaporative cooling

The Arabs hung wet blankets over doors and windows to achieve the same effect

The physics of evaporative coolingThe physics of evaporative cooling

Evaporative cooling is a natural phenomenon that

occurs when moving air passes over a wetted medium

or water source, i.e. fountain, river, sea, shower, etc.

The human body uses evaporative cooling through

sweating to maintain a constant body temperature.


Warm dry air when passing over water liberates some of

the water in the form of an evaporate. This adiabatic

process converts sensible heat (that which can be

measured by a thermometer) into latent heat.


The net result is air which has measurably lower

temperatures than ambient air (approximately 6-7 oC for

typical Irish summer temperatures) but has increased

levels of relative humidity
