Do swamp coolers actually cool the air?
Evaporative coolers, also called swamp coolers, rely on this principle. By passing outdoor air over water-saturated pads, the water in the pads evaporate, reducing the air temperature by 15°- to 40°F-before it is directed into the home.
Do swamp coolers need outside air?
Evaporative coolers produce humid air because the air absorbs water during the cooling process. These systems work best when a small amount of outside air circulates into the home while the cooler is on. Central air conditioners, on the other hand, work by taking humidity out of the home.
Where does the water go in a swamp cooler?
Before the air goes into the house, it passes through a set of damp pads, where the evaporation takes place. The cooler air goes into the house and the warmer air is pushed out. A small pump keeps the pads moist, so the water doesn't just evaporate away completely.
How cool can a swamp cooler get a room?
At lower temperatures and higher humidity, you will see less of a temperature drop. At 2% relative humidity, a swamp cooler can drop 125° F air to 83° F. However, at 80% humidity, a swamp cooler can only drop 75° F air to 72° F.
Can you leave a swamp cooler on all night?
A swamp cooler can be in operation for 24 hours of the day, but you will need to ensure it has enough water. Continuous flow coolers will automatically work and will be fine to run all day. Manual swamp coolers require you to add water to the reservoir and change the settings so it will run all day efficiently.
Do you need a window open for a swamp cooler?

What is swamp cooler?
A swamp cooler is a device that uses moisture to cool the air. Also known as a type of evaporative air cooler, these machines are designed to take in warm air and transform it into cool air using cooler pads which have water flowing on them. In the process, the cool air is blown into a space using a motorized blower and pushing it through a vent.
How often should swamp coolers be changed?
They do not work ideally in humid climates. The pads within the swamp cooler should be changed at least yearly and can be expensive – with filters commonly costing over $100 each. Thorough cleanings of these units should be done regularly to ensure the lines are clear of dirt and dust to ensure they run properly.
Why is the swamp cooler called swamp cooler?
Where Does the Name Swamp Cooler Come in? The name “swamp cooler” is a bit of a mystery, as these systems would not work well if they were installed in a hot, humid environment. It could be attributed to their ability to add humidity to the air, making dry environments somewhat more “swamp like.”.
How does a swamp cooler work?
A swamp cooler (which is also called an evaporative air conditioner) works by taking warm outside air through wet evaporative cooler pads, effectively cooling the air . The cold air is then blown into a home by a blower motor through a vent. The main parts of a swamp cooler can be found in the diagram below.
How does a swamp cooler pump water?
After there is enough water in the bottom of the evaporative cooler, the pump begins to pull water through the water distribution lines. These water distribution lines are located at the top of the evaporative pads and pour water through them. If the homeowner feels that the air isn't cool enough, they can turn their swamp cooler's switch to "pump" to pump more water into the evaporative pads.

How does evaporative cooling work?
Evaporative cooling works on one simple principle of nature that has always and will forever exist: when hot air passes over (or better yet, through) water, that air will cool off.
Why is cooler water not effective in humid weather?
To explain why they’re not effective in humid weather, just think about exactly how they work. If the air already has too much moisture in it , the cooler water that is trying to get into the air will have no room! If you live in a place with 90% humidity, that’s only 10% room for the cooler water to sneak into!
What happens when dry air passes over water?
So the dry air passes over water, the dry air will then absorb some of the cooler water, and then the temperature and vapor pressure of the water attempt to equalize with the air. As a result, the water molecules actually turn into gas molecules, and the heat switches from the higher air temperature to the lower water temperature.
Do you need a swamp to get an evaporative cooler?
And no, you don’t need to go to a swamp to get one. No one really knows where the name originated from. They’re also known as evaporative coolers. They’re a fabulous alternative to air conditioners. Or maybe you have heard of evaporative coolers and are just curious to find out how they work.
How does a swamp cooler cool down?
Our bodies automatically cool themselves down by releasing moisture through the skin; the moisture gets picked up by a pleasant breeze and brings us back down to a more comfortable temperature. A quick run through a sprinkler has the same effect. That’s essentially what a swamp cooler does to the air in a room.
