Evaporative cooling is most effective when the relative humidity is on the low side, limiting its popularity to dry climates. Evaporative cooling raises the internal humidity level significantly, which desert inhabitants may appreciate as the moist air re-hydrates dry skin and sinuses.
As the water evaporates, the air inside the cooler drops by up to 15 degrees. The wet air gets absorbed into panels built into the sides of the co. ... an evaporative cooler. These coolers have a ...
Evaporative coolers, also known as swamp coolers, are environmentally friendly, cost-effective ways to make your home and outdoor areas more comfortable. A good evaporative cooler, used correctly ...
The effectiveness of evaporative cooling is largely dependent on the humidity of the outside air; dryer air produces more cooling.

Several key considerations are important for determining if an evaporative cooling device will provide effective cooling and storage. ECCs (evaporative cooling chambers) and clay pot coolers provide the most benefits when they are used in low humidity climates (less than 40% relative humidity), the temperature is relatively high (maximum daily ...
Evaporative cooling also makes the air more humid, which can be beneficial in a dry desert climate. [130] Evaporative coolers tend to feel as if they are not working during times of high humidity, when there is not much dry air with which the coolers can work to make the air as cool as possible for dwelling occupants.
