Breakdown Of Evaporative Air Coolers
De BISAWiki
If you consult an older relative if they've heard about an cooler, they might say no. But odds are saddles they'd understand the idea behind the technology. People would sleep outside on a screened in porch to try and stay cool at night, before air conditioning or other cooler types existed. Damp sheets would be often hung by them over the displays in a try to cool the air. As the heat passed through the sheet, it was cooled. And then the cool air would gradually distribute, reducing some of the heat for the sleepers.
The same idea exists today in the shape of evaporative coolers. These products are wonderful cooling systems for those who live in warm, dry areas. They're also known by the name swamp refrigerators, but because they really wont work on all in swampy, damp conditions that can be misleading. The name probably originated from the way that evaporative refrigerators really add humidity to the air. However in fact, evaporative refrigerators need dry, hot air to work because to ensure that the air to be cooled, it has to be able to pick up (escape) some of the water. It wont get anymore water, if the air has already been saturated and it wont be cooled.
Heres how evaporative refrigerators work; the machine is composed of a fan that draws the hot dry air in the cooler, where it is passed through wet parts. The patches are kept moist by a pump that moves water through the device. As the dry air accumulates some of the water, its temperature drops, often by as much as 30 degrees Fahrenheit, depending on the climate. The cooler air is then taken into the room. An added bonus of an cooler is that the patches that cool the air also filter it. As the air passes through the pads, dust, dirt, contaminants and other toxins are caught in the materials of the pads. Therefore youll be breathing cleaner, cooler air.
Theres an additional reason we havent covered yet, if youre wondering why you ought to select an evaporative cooler over a normal air conditioning. The cost to run an evaporative cooler can be as little as 1/10 the total amount it costs to run an ac. In fact, some group energy businesses in hot, dry areas will actually provide people a discount if they mount an cooler because they understand the powerful, productive cooling capabilities of the technology. Contact your local electric company to see if they provide incentives and ask if they've any information on the potency of an evaporative cooler locally.
