Page 5: How Evaporative Air Coolers Work
HOW EVAPORATIVE AIR COOLERS WORK The evaporative cooler cools the air by means of evaporation. When water evaporates, liquid water is converted into vapor using the thermal energy in the air resulting in a lower air temperature and spot cooling effect. Evaporative cooling therefore causes a drop in the temperature of air proportional to the sensible heat drop and an increase in humidity proportional to the latent heat gain. -
