How Swamp Coolers Work?
If you have ever tried to measure the wind with a finger wet in the air, then you know what evaporative cool is. Evaporative cooling is a simple and effective way to cool down after a swim. Modern evaporative cooler, also known in the U.S.as swamp cooler or evaporative cooler, can be traced back to ancient Egypt. They are economical, efficient, and beneficial for the environment. But, don’t let your conventional air conditioner go.
Air conditioning was essential for ancient Egyptians. They did this by hanging damp blankets over their doors or, if they were royalty, having their servants fan them across jugs full of water. Hot dry air is cooled when it passes through a liquid. While electric fans have replaced servants in modern times, the principle behind cooling the air via evaporation still applies.
Evaporative coolers won’t work everywhere, unfortunately. Swamps are a poor place for swamp coolers. Although it isn’t clear exactly where the nickname came from, it may refer to the humidity that they add to the air or to the swampy smell that can form if they aren’t cleaned regularly enough.
Swamp Cooler requires a warm and dry climate to work. The U.S. has them working well in the desert western and southwest regions of the country. Swamp coolers have been around for many years and are simple, effective technology. The principles of evaporative cool worked well for the pharaohs and can still work for you.
Swamp Cooler Benefits
Swamp coolers have many benefits when used under the right conditions. It takes only a blower fan, a pump, and an 8-to 12-inch (20-to 30-cm-) thick filter pad. These can be made of either treated cellulose or fiberglass. You can find pumps and fans all over the place. Rest can be found in most local shops. Also, the swamp cooler should offer at least two speeds and one vent-only option.
The monthly operating costs of a swamp cooler are substantially lower than that of central AC. The greatest savings come in electricity. A swamp cooler uses 60-60% less electricity compared to a standard AC. It not only reduces your energy bills but also makes a positive impact on the environment.
Swamp Coolers Vs. Air Conditioners
Standard AC units operate in the same way as your home fridge. The coils cool the air before it is sent into your house. It then circulates through the machine, again and again, venting. It is a closed process. If you leave a door or window open, the cool air will escape.
Swamp coolers work in an open system. The flow of cool air through a building is what they rely upon to circulate it. Since the coolers need hot, dry, humid air to evaporate the water, the coolers must displace the existing air in the house. You can choose to use a large central unit or a small window unit. However, the air from the swamp cooler must be vented. The airflow from the swamp cooler to the different rooms of the house is controlled by opening and closing doors and windows. Central air conditioners control the flow using ducts. In some cases, swamp coolers can use ducts.
