They are essentially fans that blow air through pads soaked with water.
Make box fan swamp cooler.
Ok where i come from it gets hot.
The whole point of an evaporative cooler is to bring down the temperature by allowing a fresh water supply to dissipate into dry air.
Swamp coolers are not complicated pieces of machinery.
So hot that beer evaporates while in the bottle also the fact that my room gets a lot of afternoon sun does not make for a cool night in summer being the person i am i hacked an old newly bought bucket to create.
Evaporative coolers use the process of evaporation to cool the air up to 30 f in hard to cool areas.
They are popular in hot dry climates because they throw cool moist air through a house.
There s a good chance you have everything you need to set up a primitive evaporative cooler right at hand.
However you have to ensure that it has a large enough surface to allow space for mounting the fan.
An evaporative cooler also swamp cooler swamp box desert cooler and wet air cooler is a device that cools air through the evaporation of water.
You need to keep in mind that the capacity of the evaporator depends on the size of the container.
A fan a shallow container and some water.
This will never work.
Over at the project blog of michael colombo.
A full line up of swamp coolers in a range of sizes and cooling capacity give you option to choose which evaporative cooler you need to get the job done.

As water evaporates it naturally lowers the temperature in that area and this cold air is then blown where you need it by the system s fan.
Swamp coolers are examples of evaporation heaters.
Evaporative cooling uses the fact that water will absorb a relatively large amount of heat in order to evaporate.
