Evaporative Cooling is what you use to cool down the wind. This same principle powers the oldest and most simple form of air conditioning. They are inexpensive, efficient, and beneficial for the environment. But don’t abandon your regular air conditioner just yet.
They used wet blankets to cool their homes. If they were rich, had servants fan the blankets across the water. The air cools when dry hot air passes over liquid. Modern electric fans can be used to cool the air, but the principle that the air is cooled by evaporation will remain the same.
Evaporative air coolers don’t work in all areas. Swamps are a poor place for swamp cooler. Although it isn’t clear exactly where the nickname was given, it likely refers to the humidity and swampy smell they create when not cleaned properly.
All over the world, you will find swamp coolers. Swamp coolers need to be in a hot and dry environment. They work well in the U.S. Southwest and Western regions. The global water evaporator cooler market is valued at $7.6 Billion in 2019 and will reach $19.8 Billion by the end of 2026.
Swamp coolers have been in use for many years because they are simple and efficient. Evaporative cooling works for the pharaohs. It can also work for you.
How Is A Swamp Cooler Different From An Air Conditioner, You Ask?
Even though it is an outdated technology, evaporative cool still has some life. For instance, inventors have improved upon the centuries-old water cooling system that Ben Franklin used. They use evaporative coolers to keep vegetables and fruits cold so they don’t spoil in the heat. These coolers can be made out of many different local materials. To drain the water, an Indian example is to place an earthenware container inside a bigger, water-filled vessel. Similar coolers were found to keep tomatoes fresher for up to 20 consecutive days in Sudan. That’s 18 days more than the refrigerator would have kept them. The coolers can also be made of bricks, wooden frames, and cloth-covered bamboo.
Swamp Cooler Benefits
If the conditions are right, swamp coolers could offer many benefits. They’re easy to make and inexpensive to install. You will need a blower fan, a pump, a filter pad (8- to 12-inches) in thickness (or made of shredded or treated aspen fibers), water, and a metal box (mostly made of sheet metal). The majority of pumps and fans are readily available. All the rest can be purchased at your local hardware store. Also, the swamp cooler should come with at least two speeds and one vent-only option. The cost of a swamp cooler can range from 40 for a portable model up to 3,500 for either a ground-mounted or roof-mounted unit.
It is half the cost to operate and install a central AC. The largest savings are in electricity. A swamp cooling system uses 60-80% less electricity than a standard AC. Not only will you save money on your electricity bill but it also has a positive effect on the environment.
Swamp coolers also have an environmental benefit. Standard air conditioners depend on ozone-depleting substances to cool them.
