Mechanism, Energy-Saving, and Benefit of Evaporative Coolers
Evaporative Coolers work by drawing hot air from outside the building through a wet pad which works to cool the outside air before blowing it into the house. Thus, the air is not only cool but also humid. This process is possible through the function of several main cooler’s parts: the pump, the thermometer, the pad and the fan. Without these core evaporative parts, these air coolers will not be able to do its job.
While evaporative air coolers, also known as swamp coolers or desert coolers are an effective way of cooling your residence or business, they offer some additional benefits to your health and the environment. Powered by the natural evaporation process, desert coolers do not rely on excessive amounts of electricity and chemical-based coolants, such as Freon. With all of the energy savings and environmental benefits, swamp coolers can potentially lower your indoor temperature by as much as 30 degrees Fahrenheit. Evaporative air coolers use about 25 percent of the energy used by an air conditioning or central air unit. Even the most elaborate residential evaporative cooler system will uses 60 percent less energy than the alternatives.
These types of coolers work best in areas that do not have a high humidity. Portable evaporative coolers use special pads that cool and humidify the room. The way this works is by pulling in the hot air and pushing it through the wet pads. Once this happens the air is then cooled up to 10 or 15 degrees. Another great place to use the evaporative air coolers would be somewhere dry, with these coolers; the air would then become more humidified.
The power consumption of these coolers is limited to just a fan and water pump, so operating costs are about 75% less than the operating costs of an air conditioner. These devices also increase the humidity in the air, which can actually improve the breathability of air in dry climates.
If you’re wondering why you should choose an evaporative cooler over a traditional air conditioner, there’s one more reason we haven’t covered yet. The cost to run this type of cooler can be as little as 1/10 the amount it costs to run an air conditioner. In fact, some community power companies in hot, dry climates will actually offer residents a rebate if they install an evaporative cooler because they recognize the effective, efficient cooling capabilities of the technology. Contact your local power company to see if they offer the rebates and ask if they have any information on the effectiveness of an evaporative air cooler in your area.
People with health benefits can also benefit from using an evaporative cooler which provides a constant supply of filtered, fresh air, unlike most air conditioning units, which recirculate the same air.
One misconception is that these coolers are used to cool vast areas. This is also incorrect. However, with one of these coolers you can definitely clean up your electricity bill by football fields. These coolers take up much less electricity than the regular air conditioning unit and also are much more environment friendly. So next time you go out shopping for an air conditioning unit, just think and consider about the swamp cooler.
