Nations consume a large amount of energy through air conditioning homes, offices and plants. While air conditioners offer effective cooling in both large and small scale applications, they are not the only cooling option available for use.  If you are residing in a dry area, with relative humidity less than 50%, you can consider using and evaporative cooler instead of an air conditioner. They really save on energy.

To understand how evaporative coolers save on energy, you must first understand briefly how an air conditioner works. In an air conditioner, a refrigerant like Freon gas is used to provide cooling. It functions just like a refrigerator, without an insulated outer box. The operating costs of air conditioners are comparatively high compared to evaporative coolers.

An evaporative cooler cools the air by forcing it through moistened pads, using a fan. As the air passes through the pads, the pads absorb heat and cool the air.

Compared to an air conditioner, an evaporative cooler consumes just 25 % of electricity, yet cools the air by as much as 15 degrees.

Evaporative coolers are most suitable for places with low humidity, and provide cost effective cooling in the right conditions and climate.

Enjoy the cool and comfort of evaporative coolers. You would also be contributing to saving energy and reducing global warming.
