Evaporative cooling doesn't use chemicals to suck heat out of the air like AC does. An evaporative cooler — sometimes called a swamp cooler — only uses water and a fan to get the job done. Unlike a traditional air conditioner, evaporative coolers add humidity to the air instead of removing it.

Regarding this, do evaporative coolers really work?

As a result of their cooling process, evaporative coolers also add moisture and humidity to the air. While this is beneficial in dry climates, it also means that evaporative coolers are not as effective in more humid climates. Typically, evaporative coolers work best in areas in areas that are very dry, as well as hot.

Furthermore, how do you use an evaporative cooler? Use Your Swamp Cooler in a Dry Climate The whole point of an evaporative cooler is to bring down the temperature by allowing a fresh water supply to dissipate into dry air. As water evaporates, it naturally lowers the temperature in that area, and this cold air is then blown where you need it by the system's fan.

Also asked, what does an evaporative cooler do?

Direct evaporative cooling (open circuit) is used to lower the temperature and increase the humidity of air by using latent heat of evaporation, changing liquid water to water vapor. In this process, the energy in the air does not change. Warm dry air is changed to cool moist air.

Do you need to open windows for evaporative cooling?

An evaporative cooler should have at least two speeds and a vent-only option. Control the cooler's air movement through the house by adjusting window openings. Open the windows or vents on the leeward side of the house to provide 1 to 2 square feet of opening for each 1,000 cfm of cooling capacity.
