In low-humidity areas, evaporating water into the air provides a natural and energy-efficient means of cooling.Evaporative coolers, also called swamp coolers, rely on this principle, cooling outdoor air by passing it over water-saturated pads, causing the water to evaporate into it.hen operating an evaporative cooler, windows are opened part way to allow warm indoor air to escape as it is replaced by cooled air.
