Evaporative Cooling

About Evaporative Cooling

Evaporative cooling is an economical alternative to standard central air conditioning which is used mostly in the Western United States.

Evaporative cooling uses water to absorb a significant amount of heat from the outside air to transition to water vapor (evaporation). This evaporation will cool air and in very dry climates, it will also add moisture to the air. The concept involves pumping water from the bottom tray of an evaporative cooler up to the distributor tubes at the top of the cooler. The water is then routed through the distributor tubes and directed out to the sides of the cooler, where it drips onto the cooling media. A fractional horsepower motor is used to spin a blower cage to move the air out through the cooling media, which creates "cooled air".
