Swamp coolers consist of a thick pad, a water reservoir, a fan, and controls for tuning the results. The fan pulls hot and dry air into the machine and through the thick cooler pads. These cooler pads pull in water from the reservoir to increase the surface area. As the hot air passes through the pad, the molecules of water on the surface evaporate that causes the temperature of the air to drop. The fan, then, blows the cold air outside, where you can relish it during hot, summer days.
