About This Project:

In an evaporative cooling system, hot outside air is forced through wet cooling pads by means of a motor-driven fan. The cooling pads are moistened continuously by a water pump that delivers water to the cooling pads. The cooled down air is then blown into the building. The out coming air can then be cooled down between 60 and 90 % of the wet-bulb depending on the effectiveness of the evaporative media. The out coming air is cooled down 10 to 15 °C but contains a high amount of humidity. Therefore direct evaporative cooling is not recommended for cooling in work and living environments. 

Evaporative air cooler is a water based cooling technology. A cooling pad called honeycomb cooling media. This cooling pad is used to cool the air. Basically the cooler uses water to pass through the cooling pad. The temperature of the water makes the honeycomb cooling pad cooler. A strong blower fan used to make high flow of air for evaporation system. This high air flow while passing through the pad, makes the air cool.

An evaporative air cooler is a type of air conditioner that works by harnessing the power of evaporation to cool air temperatures. When water evaporates, it turns from liquid to gas. As it does so, the highest-energy particles leave the water first, and this leads to a drop in temperature. This is why a moist cloth on your forehead feels good on a hot day — it’s actually helping to lower your head’s temperature as the water evaporates.

The same scientific principles apply to the evaporative cooling process when it comes to your home’s air. In a dry environment, the simple process of evaporation can help lower the temperature of the air. You may have felt this for yourself if you’ve ever misted the air around you to feel cooler on a hot summer day. An evaporative air conditioner uses the same idea, but it adds technology to make the process more efficient — and less messy — than just spraying a room with water and hoping for the best. Evaporative air cooler has no Compressor inside.
