Evaporative air cooler, popularly known as swamp cooler, is definitely the most preferred cooling systems. This is thanks to their lower energy consumption, high cooling efficiency, environmental friendly nature, and reasonable cost. However, unknown to many people, this appliances comes with some symbols or tricks that make them produce more effective cooling. In this article, we will discuss about something you may not know about evaporative cooler. A simple example of natural evaporative cooling is perspiration, or sweat, secreted by the body, evaporation of which cools the body.

Just before drinking, a tab is pulled so that the desiccant comes into contact with the liquid and dissolves. As it does so, it absorbs an amount of heat energy called the latent heat of fusion. A closely related process, sublimation cooling, differs from evaporative cooling in that a phase transition from solid to vapor, rather than liquid to vapor, occurs.

The air coming out of the coolers is humid because of the evaporated water this adds to the humidity in the air. If you are buying a new air cooler then opt for one with humidity control.

Potent Performance

Passive direct evaporative cooling can occur anywhere that the evaporatively cooled water can cool a space without the assist of a fan. This can be achieved through use of fountains or more architectural designs such as the evaporative downdraft cooling tower, also called a “passive cooling tower”. The passive cooling tower design allows outside air to flow in through the top of a tower that is constructed within or next to the building.

Additional information

Before the advent of modern refrigeration, evaporative cooling was used for millennia, for instance in qanats, windcatchers, and mashrabiyas. hvls fan would cool water by evaporation through its walls; frescoes from about 2500 BCE show slaves fanning jars of water to cool rooms. Alternatively, a bowl filled with milk or butter could be placed in another bowl filled with water, all being covered with a wet cloth resting in the water, to keep the milk or butter as fresh as possible .

While the concept of evaporating cooling has been around for a long time, the root of Air conditioning dates back to the second century China. During this time is when an inventor known as Ding Huane designed a rotary fan that was manually powered. The concept of air cooling was also used by Benjamin Franklin, an American inventor and statesman, to conduct several experiments involving evaporation and alcohol while trying to attain freezing temperatures. However, the first modern air conditioner was designed by Willis Haviland Carrier in 1902. Mass production of evaporative coolers began around the year 1939. Most designs take advantage of the fact that water has one of the highest known enthalpy of vaporization values of any common substance.
