A swamp cooler uses moisture to cool air. 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.

Does a swamp cooler need outside air?

While an air conditioner is most efficient in a sealed and insulated environment, swamp coolers actually do best with a steady stream of fresh air. As you run a swamp cooler, it makes moist air in your home as water evaporates into the air.

Does a swamp cooler require electricity?

A swamp cooler only needs electricity to power a simple fan and water pump. According to the U.S. Department of Energy, they use only a quarter of the energy that a central AC compressor uses. For budget savvy consumers, the swamp cooler is the more economical choice for summer cooling.

Does a swamp cooler use a lot of water?

Swamp coolers need a constant supply of water. As water keeps evaporating from the unit to cool the air, more water needs to replace it. Most water use estimates range from 3 to 15 gallons / 11 to 57 litres per hour, with averages between 7 and 11 gallons / 26.5 and 40 litres. … Size of the unit.

Do you open windows with a swamp cooler?

A Swamp Cooler Will Require Open Windows In order for the unit to work properly, the pads should be damp, not soaked.

How cold can a swamp cooler get?

Portacool evaporative coolers CAN drop the air temperature up to 30°F when the air is very dry such as arid climates of the Southwest where relative humidity is typically 30% or less. That said, even in hot and humid areas such as Houston, you can still expect to achieve a 10°F-13°F drop in temperature.

How many windows should I open for a swamp cooler?

Open the windows or vents on the leeward side of the house to provide 1 to 2 square feet of opening for each 1,000 cfm of cooling capacity.

How much power does a swamp cooler draw?

An evaporative cooling system uses between 400 and 700 watts, depending on the size of the system and the fan. As well, the power consumption can be as little as 60 watts. That in itself is a lot of savings on energy consumption.

How many gallons of water does a swamp cooler use per day?

Overall, the national average is two gallons per kWh of electricity consumed. The evaporative cooler runs on 450 watts; a three ton conventional unit uses ten times that, consuming running at 4500 watts, or about 4 kWh every hour more if running constantly. That production consumes 8 gallons of water on average.

Can you use a swamp cooler and AC at the same time?

If you have both an evaporative cooler and central air unit, do not run them at the same time. Doing so would cause the two systems to work against each other. If you have central air, there is no need to crack a window or open a door to make the system more effective.

Is swamp cooler better than AC?

In short, you want a swamp cooler for a dry climate or an air conditioner in a wet one. Swamp coolers are quieter, cheaper, and easier to use – but they’re not as advanced. An air conditioner will cost you more – but in return you get great cooling, dehumidifying, and accurate temperature control.

Do swamp coolers save money?

The swamp cooler requires far less electricity thereby saving money. For example, if electricity costs $0.15 per Kwh (Kilowatts per hour), it takes $1.13 per hour to operate an A/C system. It’s only $0.26 per hour to run the cooler. That’s real savings.

Will a swamp cooler work in a garage?

Swamp coolers, known also as evaporative coolers, are an environmentally friendly way to cool your garage quickly inside or out. Perfect for both commercial and residential use, they work the best in a hot and dry climate and can be especially effective in a garage or large spaces like a warehouse.

Can you use a swamp cooler in a closed room?

Using a water cooler with the water pump ON is a very bad idea inside a concealed room. Air cooler works on the principle of evaporative cooling, in which water gets mixed with air before it comes out of the cooler. Due to evaporation the water in liquid form turns into vapor causing cooling.

Can you put a swamp cooler inside?

Evaporative coolers can be used in outdoor or semi-outdoor areas (like garages, porches and backyards) anywhere in the country – even if you live in humid conditions. Swamp coolers do, however, add moisture to the air as they cool. If you live in a typically humid and hot climate, then don’t use them indoors.

How do you operate a swamp cooler?

1. Turn the pump on – The first step is to turn the pump on to wet the pads before turning on the fan. If you have a manual control always turn the pump on for approximately 5 minutes to ensure the pads get wet enough. …
2. Always open a window(s) – when running your swamp cooler.

Do swamp coolers work at night?

Evening hours are a great time to run the swamp cooler. You can optimize airflow for dinner-time comfort and relief.

At what temperature do swamp coolers stop working?

A wet bulb temperature above 70 degrees Fahrenheit (21 degrees Celsius) means the swamp cooler won’t be able to adjust the temperature enough to keep it in the comfort zone. (This varies based on humidity, personal preference and activity, but it generally falls in the low 70s.)

Does ice in a swamp cooler work?

In actual practice, adding ice to your swamp cooler only has a limited effect. … It’s the combination of temperature and humidity in the ambient air that determines how much of a boost ice provides, not the ice itself. In fact, adding ice to your evaporative cooler might actually hamper the cooling process.

Where does the heat go in a swamp cooler?

Warm Air is Pulled Through Evaporative Cooler Pads After the evaporative pads have water on them, the blower motor begins pulling warm air into the swamp cooler, through the pads. As the warm air goes through the pads, the moisture cools the air, and cleans it. This process is called evaporative cooling.

How do you prevent calcium build up in a swamp cooler?

1. Use Quality Pads. The quality of cooler pads you use on your evaporative cooling unit determines your coolant’s ability to prevent deposit accumulation. …
2. Clean the Cooler Regularly. …
3. Add a Bleed-Off Valve. …

It costs roughly $20 per month to run a swamp cooler, but this total can vary. This accounts for about $5 in water and $15 in electricity, for a unit running 8 hours and using 80 gallons of water per day.

Does swamp cooler add humidity?

The short answer is yes, evaporative cooling does increase humidity. … For example, a humidity level between 40 and 60% reduces the spread of dust and viruses within a production facility or building. Furthermore, it brings a level of comfort as the air that is too dry can irritate the eyes and throat.

Is a swamp cooler cheaper than air conditioning?

Swamp coolers generally are cheaper to install and use less electricity than air conditioning. They also perform the same job as humidifiers. … This makes swamp coolers much more effective here than in other areas. Second, they tend to require more maintenance.

How energy efficient is a swamp cooler?

Overall swamp coolers have been found to be far more energy efficient for home cooling. Swamp coolers will use 15% to 35% of the energy that most traditional AC units would use. They also do not require any chemicals in the way that traditional AC does. This can be better for the environment.

Is evaporative cooling cheap to run?
