Where would an evaporative cooler be most effective?

Where would an evaporative cooler be most effective?

As this map shows, evaporative coolers work best in the dry areas of the United States (red areas marked A) and can work somewhat in the blue areas marked B. In the humid eastern U.S., normal air conditioners must be used.

At what humidity level do evaporative coolers become ineffective?

Don’t purchase the wrong type of cooler for your environment. Although evaporative coolers are energy-efficient and affordable cooling devices, they’re only suitable in certain environments, particularly in areas where temperatures rise above 80° F and humidity levels below 50%.

How effective is an evaporative air cooler?

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.

Can an evaporative cooler cool an entire house?

Outdoor evaporative coolers called down discharge (or down draft) coolers are designed to be installed on the roof and can cool an entire home.

Do I live in the right climate for an evaporative cooler?

Do I live in the right climate for the evaporative cooler? In areas experiencing high temperatures and low humidity, evaporative coolers effectively lower temperatures to as low as 20 – 40 degrees Fahrenheit. However, in instances of high humidity, the cooler cannot cool you down effectively.

At what dew point do evaporative coolers not work?

If you want to gauge a cooler’s efficiency in terms of dew point, just keep in mind that, in general, a dew point in excess of 55 is generally a swamp cooler humidity limit.

At what temperature do evaporative coolers stop working?

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.

Which is better air conditioner or evaporative cooler?

Traditional air conditioners take a lot of energy and power to run and typically have higher levels and rates of emission than evaporative coolers. The upside is the AC units are powerful enough to cool an entire house or a large indoor area. Evaporative coolers have much lower emissions than AC units.

How much does evaporative cooling reduce temperature?

15°- to 40°F
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.
