When you consult an older relative if they have heard of an evaporative cooler, they might say no. however, chances are they would recognize the thought behind the science. Just before other cooler or air cooling types existed, people would sleep outdoors for a screened in porch to try to remain cool at night. They'd often hang damp sheets with the screens in an attempt to cool the air. As the hot air passed throughout the sheet, it was cooled. Then the cool air would gradually circulate, relieving some of the heat for the sleepers.
The same concept exists today in the type of evaporative coolers. These machines are perfect cooling mechanisms for folks who are now living in hot, dry climates. They are commonly known as by the term swamp coolers, but that might be misleading since they actually will not have all in swampy, humid conditions. The name probably came from the way that evaporative coolers actually add humidity on the air. But in reality, evaporative coolers need dry, air that is hot to work since to enable the air to be cooled, it's to have the ability to pick up (evaporate) some of the water. In case the air is already saturated, it will not get any more water and yes it won't be cooled.
Here is exactly how evaporative coolers work; the machine is composed of a fan that pulls the warm dry air inside the cooler, where it is passed through moist pads. The pads are kept damp by a pump that circulates water through the device. As the dry air picks up some of the water, its temperature drops, sometimes by pretty much as thirty degrees Fahrenheit, depending on the local weather. The cooler air is then blown into the space. An added benefit of an evaporative cooler is that the pads that cool the air also filter it. While the air passes through the pads, dust, dirt, other toxins and allergens are taken in the fibers of the pads. So you'll be breathing cleaner, cooler air.

An Old Idea Finds New Life In An Evaporative Cooler
If you are wondering why you must choose an evaporative cooler with a regular air conditioning, there is one other reason we haven't covered yet. The price to operate an evaporative cooler is often as small as 1/10 the amount it costs to run an arctos portable ac size. In fact, several community power companies in warm, dry climates will in fact offer residents a rebate if they install an evaporative cooler because they recognize the effective, efficient cooling abilities of the science. Get hold of your local energy company to find out if they offer the rebates and ask if they have any information on the usefulness of an evaporative cooler in the area of yours.
