The formula for calculating evaporative cooler sizing for indoor use is as follows: Take the square footage/feet of the space that needs cooling x the ceiling height (in feet), take this number and divide it by 2 or cut it in half and that’s how much CFM you want.
How do I choose an evaporative cooler?
Sizing and Selection Evaporative coolers are rated by the cubic feet per minute (cfm) of air that they deliver to the house. Most models range from 3,000 to 25,000 cfm. Manufacturers recommend providing enough air-moving capacity for 20 to 40 air changes per hour, depending on the climate.
What is the standard size of a swamp cooler?
The CFM of swamp coolers ranges from 700 up to 20,000, covering spaces from 200 square feet up to 4,000 square feet. The physical size and dimensions of swamp coolers can be as small as two feet by two feet by one and a half feet. They can be as large as seven feet by four feet by four feet.
Can a swamp cooler be too big?
Signs of an Oversized Swamp Cooler Having your swamp cooler supply too much air can also cause problems in the kitchen. The biggest concern is that it can create air currents that will blow the exhaust plumes out of alignment with the exhaust hoods and interfere with the hoods’ ability to capture hot, greasy air.
Are evaporative coolers worth it?
Under dry, hot conditions, an evaporative cooler can work just as well as a refrigerant-based air conditioner. Even on 90°F days with average humidity, an evaporative cooler can lower a home’s temperature to a comfortable range. The lowdown: an evaporative cooler is definitely worth considering.
Which brand of evaporative cooler is best?
1. Hessaire MC37M Portable Evaporative Cooler. If you need to reduce the temperature in a large area — think garage, master bedroom, or small patio — Hessaire’s evaporative cooler is the right choice.
Can I use air cooler in closed room?
You can use your air cooler just like a fan in a closed room by turning off its water pump. If you are thinking of using an air cooler in a closed room then it is advisable that you use it just like a pedestal or table fan. Due to evaporation the water in liquid form turns into vapor causing cooling.
What size motor do I need for my swamp cooler?
Evaporative cooler motors are relatively small in size, usually ranging from 1/3 to 1 horsepower. Most operate on 115/120 volts of power, which is the reason they use relatively little electricity when compared to 240-volt central air conditioning systems.
How do you measure a cooler?
How big? Cooler capacity is generally stated in quarts or capacity in 12-ounce cans. One quart equals about 0.75 cans, so a 24-quart cooler will hold about three six packs or 18 cans. Another way to gauge capacity is to divide the capacity in quarts by 30, so a 60-quart cooler equals two cubic feet.
How do you measure a swamp cooler for a cover?
To measure a side discharge or down discharge swamp cooler for a cover, measure the width, depth and height of the unit in inches. Side draft and down draft cooler covers are listed as “width x depth x height.” If your cover requires a corner be split to accomodate tubing, see Locating Cooler Cover Split Corners.
How do I know what size swamp cooler I need?
The formula for calculating evaporative cooler sizing for indoor use is as follows: Take the square footage/feet of the space that needs cooling x the ceiling height (in feet), take this number and divide it by 2 or cut it in half and that’s how much CFM you want.
How do I make my swamp cooler colder?
10 Tips to Make Your Swamp Cooler Colder and More Efficient Use Your Swamp Cooler in a Dry Climate. Use Your Swamp Cooler Seasonally. Open the Windows. Run a Dehumidifier. Cultivate a Green Thumb. Experiment With Positioning. Prime the Pads First. Use Cold Water.
Can you double up swamp cooler pads?
Swamp cooler pads can be doubled up to increase cooling effectiveness as this increases surface area and water retention. One is air flow rate and other is water retention by your cooler pads.
How many windows do you need to open with evaporative cooling?
In any case you’ll need more than one window open. Normal rule of thumb is that for every ceiling outlet you need windows/doors left open to outside equivalent to twice the area of each vent.

Do small evaporative coolers work?
According to the US Department of Energy (DOE), an evaporative cooler can successfully reduce the ambient temperature by 5 to 15 degrees—but even the DOE is quick to clarify that this process works only in areas with low humidity.
Do you need to have a window open with evaporative cooling?
To get the most of the evaporative cooling system, it is important to leave your windows partially open as it allows warm air to escape as it is being replaced by cooler air.
