What is evaporative cooling? How does an evaporative cooler work?

What is evaporative cooling?
The Egyptians, Romans and Greeks where the first ones using pads (at that time wet mats). Nowadays the heart of an evaporative cooling system is the pad where the water evaporates and the air passing through the pads is cooled.
 
Evaporative cooling pads, like Küül-pads are manufactured of fluted cellulose sheets that are glued together. This material is chemically impregnated with special compounds to prevent rot and ensure a long service life. 

A special water distribution system spreads water over the surface of the pad, ensuring an uniform supply of water to keep the entire air contact surface thoroughly wetted. Fans create a negative pressure, causing air to be drawn through the pads. Evaporation results from contact between air and water. A control system operates the water pump and the fan distributes the cool air.

The PORT-A-COOL® Portable evaporative cooler
PORT-A-COOL®´s operating costs are much lower than those of a central air conditioner. The initial equipment cost is also lower than air conditioners. Along with lower operating costs and simple installation, evaporative cooling can be a perfect, ozone-friendly alternative to traditional air conditioning.
 
It operates at a 10th of the cost of conventional airconditioning and is capable of cooling hundreds of square meters 7 degrees or more, saving PORT-A-COOL® customers hundreds, or even thousands euros per season!

Since PORT-A-COOL® is a state of the art, high efficiency, portable evaporative cooling system, its high efficiency cooling media coupled with a unique housing design, allows PORT-A-COOL® to cool effectively in very high relative humidity conditions. Since, as its name implies, it is portable, PORT-A-COOL® can be easily moved around shops, factories, back yards, sporting events and hundreds of other areas for maximum effectiveness, comfort and increased productivity.

PORT-A-COOL® uses a specially designed ridged cooling media, contained in a properly designed housing to insure effective direction of the air over the water saturated media at the proper air velocity.
