What is a swamp cooler?
Swamp coolers use the principle of evaporative cooling in order to achieve the direct result of cooling the air. When one thinks of a swamp cooler, nothing probably comes to mind because the term "swamp cooler" is one that is not often used, but the principle of evaporative cooling is actually often used.

A couple examples of swamp coolers include humidifiers and dry cleaning buildings. These two examples use swamp coolers to cool the air around them because the air inside them or surrounding them is already humid. Some air conditioners also use the swamp cooler principle as a way of cooling the air as in the same way as a humidifier works. For example, a mist cooler or fan blows small drops of water into the air, and they are so small that they instantly evaporate. This evaporation is enough to cool the air around it to sometimes a drop in temperature of thirty to thirty-five degrees Fahrenheit. When considering a swamp cooler as an actual air conditioning unit, one may consider it as a less expensive way to cool the room or place that they need cooling.
There are basically two types of swamp coolers. The two types are the direct evaporative cooling system and the indirect cooling system. Both of these systems basically use evaporation in the way as it was described above. The only difference about the indirect cooling system is that is uses some type of heat exchanger, like a radiator or other device, to achieve the same end result as the direct evaporative cooling system.
Using a swamp cooler is a good way for households or commercially owned buildings located in dry climates to use a less expensive method of cooling the air that it needs. Swamp coolers, also known as evaporative cooling, should definitely be considered among all the other options out there!
