Evaporative coolers are cooling devices based on the principle that water absorbs heat when it evaporates. In basic terms, warm air is drawn through some sort of wet filter and comes out colder on the other side.
This type of cooler has been in use since ancient times, though obviously the modern versions are way more effective. Hanging a wet sack in the window of your bush shack on a breezy day was a primitive form of evaporative cooling. In late 19th-century Australia, food was kept fresher with clever evaporative-cooling invention the Coolgardie Safe.
The Benefits of Evaporative Cooling
Benefits include (but are not limited to):
Rather than recycling the same air over and over again as is done with mechanical cooling, evaporative cooling needs to continually bring in fresh outside air in order to work. This outside air is generally filtered, too.
Evaporative coolers also add moisture to the air, which can help to counteract the natural dryness in certain climates.
Thirdly, unlike other air-conditioning, evaporative coolers don’t require the use of potentially harmful-to-the-environment refrigerants. On top of this, they tend to be much more energy efficient, making them an even more eco-friendly choice than their counterparts.
The Drawbacks of Evaporative Cooling
Evaporative coolers require a steady supply of water, and if this water contains impurities, it can cause problems with the device’s efficient/safe operation.
These coolers also struggle to perform at their best in humid conditions. They will make the air even more humid, which is obviously not ideal in an indoor situation.
