An evaporative air cooler is a type of air conditioner that works by harnessing the power of evaporation to cool air temperatures. When water evaporates, it turns from liquid to gas. As it does so, the highest-energy particles leave the water first, and this leads to a drop in temperature. This is why a moist cloth on your forehead feels good.. Evaporative coolers are made up of four essential parts: a fan, a water tank, filter pads (sometimes called media) and an internal motor. The motor pulls warm air through a wet internal filter pad, where the evaporation process quickly lowers its temperature before it is circulated back into the room. The internal pads also act as a filter.
