Swamp Coolers, a primer on evaporative cooling – Swamp coolers are based on the natural process known as evaporation but crucially, only effectively work in low-humidity areas.

About Swamp Coolers

So, how do they work? The idea behind swamp coolers is that evaporating water is cooler than the air around it, typically 20 to 40 degrees cooler. Given this fact, swamp coolers work by sucking air from the exterior of your home across pads saturated in water. As the cooled off air enters the home, it sinks, pushing the rising hot air out of the house. And yes, it really works. coolers are used, particularly in low humidity environments, to lower the temperature within a house or other building during the summer months. Swamp coolers are efficient and effective machines of cooling, being as they are based on the natural process known as evaporation. That’s why swamp coolers are also called evaporative coolers and they can be installed on the roof or can be portable indoors. Swamp coolers are much cheaper to operate, so they are are an energy-saving alternative to refrigerated air conditioners. They use about one quarter of the electricity that a conventional A/C uses.
