An evaporative cooler is a cooling device that is also known as desert cooler, swamp cooler or wet air cooler that cools air by evaporating water. The cooling system is quite different from the typical air conditioning system that uses absorption refrigerator cycle or vapor compression. Such coolers are cost-effective alternatives, healthy and eco-friendly, compared to other air conditioning systems in the market.
How to Be Sure If an Evaporative Cooler is Worth Buying?
An evaporative cooler is known for cooling indoor spaces. It comes cheap and easier to handle. Well, convincing you to have such item, let’s find how feasible it is to get an evaporative cooler concerning the climate you live in.
Evaporative cooling is a natural process happening around all of us. You feel cold after you step out of the pool on a scorching hot day. It happens because of the dry air runs over the water and absorbs it. The absorption of water takes place when vapor pressure and air temperature are trying to be equal. In this way, water molecules turn into gas molecules, and the high temperature meets the water temperature. Due to the natural circulation of air, the area becomes cool.
To get an effective cooling with a swamp cooler, a hot and dry weather of the dry areas, such as the southwestern United States is more convenient. Even, during the hottest time of the day, when humidity is below 50%, is considered as the most efficient time to run evaporative coolers for most satisfying results. The machine is ineffective in areas where there is a lot of humidity, such as the southeastern United States. In humid climates indoors, build moisture that cannot give you the cooling effect as expected. If you are planning to install the evaporative cooler in semi-outdoor and outdoors like garages, sporting or gathering event, it will not disappoint you.

It uses the fan to draw the warm air inside the unit, and the hot air passes over the pads moisturized with cool water. In this process, air can be cooled up to 20 degrees, and the air is being circulated by creating a light wind across a certain space you want.

Even, there are types of evaporative coolers that require window mounting or small setup to place the air filters.
As far as energy efficiency is concerned, swamp coolers use a refrigerated cooling system that costs up to 50% less. If you see it logically, a 36-inch dessert air cooler that operates for 8 hours a day costs less than one dollar. It is because of its only use of water and electricity. Hence, it costs 3 times less than traditional cooling system.
Last but not the least, caring and maintaining swamp coolers is a bit different, and it takes minimal effort to do so. Proper shutdown/shortage and some basic cleaning efforts determine the longevity and performance rate of an evaporative cooler. The attached water curtains and filters need to be cleaned once in every two weeks with mild detergent and lukewarm water. Cleaning in such a way can wash off the dust, mildew, mould, and dirt, etc., that build up due to its usage since a long time.
