Swamp Coolers or Evaporative Coolers are an extremely affordable way to cool your home. In fact, this method has been used since Ancient Egypt! Nowadays, electric fans are used instead of evaporation but the same idea remains.

Arizona is a perfect state to use Swamp Coolers! Because the climate is dry and water vapor can cool the air by breaking down the kinetic energy of heat, swamp coolers are a perfect alternative to ac units that can cost hundreds of dollars a month.

How does Evaporative Cooling or Swamp Coolers work? In short, heat is used to evaporate water into vapor. This changes the liquid water to vapor and that vapor is used to cool the air. Because water broken into smaller pieces lowers the kinetic energy of the air, cooling evaporation happens!
