How Does an Evaporative Air Cooler Work?

An evaporative air cooler, also known as a swamp cooler, operates on a simple and efficient cooling mechanism. Unlike traditional air conditioners that use refrigerants and compressors, evaporative air coolers work by utilizing the natural process of evaporation.

When hot air passes through the cooling pads soaked in water inside the evaporative air cooler, the water molecules on the pads evaporate, cooling down the air. The cooled air is then circulated back into the room, providing a refreshing and comfortable environment.

The cooling pads in an evaporative air cooler are typically made of a honeycomb-like material that is designed to hold water. These pads facilitate the evaporation process, ensuring maximum cooling efficiency. The fan inside the unit pulls air from outside into the cooler and pushes it through the damp pads, allowing for evaporation to occur.

One of the advantages of evaporative air coolers is that they require minimal energy to operate. Unlike air conditioners that need significant power to compress and cool refrigerants, evaporative air coolers simply rely on the natural cooling effect of water evaporation.
