Build Refreshing Evaporative Swamp Cooler DIY Project

Many of today’s DIYers are always looking for ways to use their skills in order to either repurpose some old stuff they have around the home or are wanting to save themselves money by not having to buy an expensive air conditioner in order to supply cooler air.

An evaporative cooler (also swamp cooler, desert cooler and wet air cooler) is a device that cools air through the evaporation of water. Evaporative cooling differs from typical air conditioning systems, which use vapor-compression or absorption refrigeration cycles. Evaporative cooling works by exploiting water’s large enthalpy of vaporization. The temperature of dry air can be dropped significantly through the phase transition of liquid water to water vapor (evaporation). This can cool air using much less energy than refrigeration. In extremely dry climates, evaporative cooling of air has the added benefit of conditioning the air with more moisture for the comfort of building occupants. Wikipedia (
