Evaporative air cooling is the natural process of cooling, similar to wind flowing across a lake. Evaporative air coolers delivers 100% fresh filtered cool air at much lower cost than a refrigerated air conditioner. Thus evaporative cooling is the most viable & economic option for cooling large & open areas. There is no need to shut doors & windows. Rather when doors & windows left open, it works more efficiently.
Evaporative air cooler systems contain no harmful synthetic refrigerants. Many of the gases used in refrigerated air conditioning are potent greenhouse gases like hydrofluorocarbons or chlorofluorocarbons which deplete the ozone layer. CO2 emissions are many times less with evaporative air cooler.
