HOW EVAPORATIVE AIR COOLERS WORK

Evaporative coolers cool air by means of evaporation. Our bodies are great evaporative coolers. If

you have ever felt the cooling sensation of air blowing across your skin after getting out of the

shower or swimming pool, or after sweating from working out, you have felt the effects of evaporative

cooling. The water or perspiration on your skin evaporates, removing latent heat that was in the

water and leaving the surface of the skin cooler. Evaporative coolers operate on this same principle.

Hot air is drawn across media which has been soaked with water. The water absorbs this heat and

evaporates leaving the exiting air cooler and more humid.

Evaporative coolers work best in dry climates. Dry air can absorb more water from evaporation than

humid air, removing more heat and providing cooler temperatures. Even humid air can provide some

cooling effect, unless it is 100% humid, however the amount that the temperature can be cooled will

be much less than with dry air. The cooler might still provide spot cooling relief, but may not be able

to cool a room or space as well. The recommended relative humidity for optimum operation is 60% or

less.

An evaporative cooler should not be used in an enclosed or sealed space. It requires adequate

outside dry air to pull into the media. The humid air that is leaving the cooler must also be exhausted

so that the humidity in the area does not build up and decrease the cooling effect. Well ventilated

areas such as on a porch are fine, but if using in a room setting, doors and windows should be open

on opposite sides of the room to allow cross air flow.
