An evaporative cooler, commonly called a swamp cooler, cools the air by evaporating water. The goal is to utilize the natural cooling properties of phase transition from liquid water into water vapor, which cools the air more efficiently than refrigeration. Evaporative cooling is one of the oldest methods for cooling homes, going as far back as Ancient Egypt, where they would hang wet sheets over windows and let the breeze blow cool air inside. Today, technology and modern service methods make swamp cooler installation a viable alternative to cooling your Denver home.
