The Importance of a Desert Cooler
Did you know that the largest desert in the world has no sand in it whatsoever, and is in fact covered entirely with a thick blanket of snow and ice? The Antarctic Desert in Antarctica holds this honor. Not only is the Antarctic the coldest place on earth, but it's also one of the driest, with an average precipitation of only eight inches each year! As you can imagine, there isn't much need or desire to make that desert cooler. The rest of the world's deserts are a different story.
Other than the Antarctic Desert, the rest of the world's largest deserts can be found in Africa or Asia. By comparison, the largest desert in North America is one twentieth the size of its African counterpart. But whether you are in Africa, Australia, or even just the middle of Arizona, the climates are quite similar. And quite warm!
Desert climates, such as those found in the Sahara Desert, or even just the Southwestern United States, are known to be extremely dry and very hot throughout the day. Not only are these areas uncomfortable, but the combination of heat and lack of humidity can be quite unhealthy -- even deadly to some people. Which is why staying cool in these areas is so important. However, in these climates, traditional means of cooling are not always the most effective. They're also not nearly as efficient as they would be in more humid climates. In these arid areas, an evaporative cooler, also commonly known as a desert cooler, is by far the most effective way to stay cool - and safe!
Desert coolers, also known as swamp coolers or simply air coolers, use the power of evaporation to provide a cooling effect. The easiest way to describe the cooling provided by one of these units is to imagine standing next to a waterfall, and feeling the mist cooling you off. These units are comprised of a fan -- ranging in size depending on the unit -- and a type of pad that is soaked with water. The desert cooler's fan takes air from your surroundings, and blows it through the wet pads, where it is cooled through the power of evaporation. The cooler air is then re-distributed throughout the room or area.
In the proper climate, an evaporative desert cooler can lower the surrounding temperature by up to 20 degrees. These air coolers also serve to humidify the immediate area as well. Best of all, desert coolers can also save you money.
The traditional air conditioner requires a large amount of power and energy to function, especially in an extremely warm climate. Desert coolers, by contrast only require a fraction of that amount. Running an evaporative swamp cooler will only cost a few cents a day on average. Add the cost saving to the cooling potential of these units, and it's easy to see just how important these coolers are -- especially if you call one of the world's many deserts home.
