How swamp cooler works

How it Works

A swamp cooler uses the basic principle of evaporation along with simple technology and electrical power to create cold airflow. First, one motor pumps water into pads of a fibrous, absorbent substance similar to hay, called cellulose. Then another motor powers a fan that pushes air through the pad, which is always pregnant with fresh water.

Benefits

Not only does a swamp cooler lower the temperature of the air, it also makes the atmosphere more pleasant. The chilled air is slightly damper and always freshly recirculated. This gives the swamp cooler many advantages over an air conditioner
