How does air cooler works without water?

How does Air Cooler Work Without Water? Direct evaporation is used in both residential and industrial state shift coolers, which are described by an inside metal or plastic box with ventilated sides. A centrifugal fan or blower drives the air, and a water pump wets the evaporative cooling pads.

What is the working principle of air cooler?

An air cooler works on the principle of evaporative cooling wherein evaporation of water is used to cool the air. A simple example of evaporative cooling is sweating in humans. As sweat starts to evaporate, it extracts the extra heat absorbed in it from the skin in the form of gas thus resulting in a cooling effect.

Does cooler work without water?

The common misconception is that air coolers, like air conditioners work efficiently, if they are placed in closed spaces. That’s not true. Air coolers work on the basis of evaporation, by blowing hot air through cooling pads that have been soaked with water. Hence a smooth airflow is essential for its cooling.

Does air cooler work on electricity?

Air coolers consume up to 10 times less energy than ACs. They consume less electricity and can also work in low voltage areas. Monthly electricity / power bills are significantly lower.
