Many people prefer evaporative cooling because, typically, it is less expensive to install, run and maintain. It provides 100% fresh air rather than recycled air. Air cooled by water means it won’t dry out the air or irritate your eyes or throat. Windows/doors can be left open, allowing you to enjoy outdoor living.
EVAPORATIVE AIR COOLING PRINCIPLE:
Evaporative air cooling is a natural, age-old process. In olden days people often used hand water soaked bed sheets and blankets in windows and doorways, relying on natural wind or fans to pump air through moist cloth.
The principle underlying evaporative cooling is the fact that water must have heat applied to it to change from a liquid to a vapour. The required heat is drawn from the outside air.
Eco Cooling air coolers are a refined concept of age old practice, providing an alternative to refrigerated air conditioning by being
1) Low Power Consumption
3) Highly Efficient
Evaporative air conditioning uses evaporation to cool the air. In an evaporative cooler, a pump circulates water from the reservoir on to a cooling pad, which in turn becomes very wet. A fan draws air from outside the unit through the moistened pad. As it passes through the pad the air is cooled by evaporation.
The 3-step air cooling process is very simple and no less effective than modern refrigerated air-conditioning technologies.
Step – 1:
An air moving system pulls fresh outside air and drives it through the moist cooling pads.
Step – 2:
The water in the pads evaporates, bringing down the temperature of the air passing through the cooling pads.
Step – 3:
The blower then blows the cool 100% fresh air into the room.
