Evaporative Air Cooling System

The process of evaporation has been around forever with it being the precursor for cloud formation and rains. It is a simple process where water evaporates from a surface, giving rise to vapors that can cause cooling if stored properly.  Man has used this technique to cause effective cooling around himself with the help of coolers and fans.

With central air conditioning becoming the norm for cooling around the world, a number of technologies are being developed in this sector. No technology however is as simple or as effective as the evaporative air cooling system.

The system originates from the basic principle of evaporation but on large industrial scales. Using this, water is poured on specially created pads that lead to vapor formation which is then condensed and circulated around an area. This is done to bring down the temperature of a place and maintain sufficient humidity levels.
The pads are made up of ecofriendly raw materials that can retain water for long periods of time giving continuous chilling. The warm air from the outside comes in contact with these wet pads and begins evaporation, which through ducts and other openings is sent to all parts of the building in the form of cool air. The pads also are quiet sturdy and do not need to be changed frequently.

They can be used for refrigeration of establishments like greenhouses, malls, poultry farms, pharmaceutical industries or places where the temperature needs to be constantly monitored and maintained like dry cleaning facilities. Earlier this was thought to be a very expensive technology but with prices of raw material coming down, its popularity has soared in recent times.

The USP of evaporative air cooling system is that it is extremely ecofriendly and suitable for all buildings. With the addition of solar panels to harness the solar energy for running this system, it is one of the cleanest ways to chill a big, commercial space. It is very user friendly in its operations and does not require much after sales maintenance.
