Once it’s above 75 percent, they lose effectiveness and can actually make things feel worse as they tend to make the air more damp. Web the direct evaporative cooling process in a psychrometric chart. Web this chart shows that as indoor air temperature rises, an evaporative cooler will become more effective at cooling air as the relative humidity drops. Web according to this swamp cooler chart, at 80 degrees f at 80% relative humidity, you can drop the temperature 3 degrees. Example temperature & humidity graph.
There are big differences between hot and arid climates like arizona versus hot and humid climates like florida. Web if you want to check this, you can calculate the relative humidity from the dew point and the outdoor temperature, and you can use that to look up the cooling potential of a swamp cooler on an evaporative cooler humidity chart. Web what is the ideal humidity for the evaporative air coolers to be the most efficient? Web if you take a measurement of the air temperature and relative humidity in your town, you can use this chart to determine if you have optimal conditions to run an evaporative cooler. Web usually, 1 or 2 square feet per 1,000 cfm of cooling capacity is sufficient to allow hot air and humidity to be pushed outside.
Here’s an overview example of the heat/humidity with expected temperature drops from evaporative cooling: Web that’s the evaporative cooler humidity chart. Web what is the ideal humidity for the evaporative air coolers to be the most efficient? Perfect for larger patios and workshops, the model mc61v weighs 57 lbs empty and measures 28” wide by 46” tall. Web the direct evaporative cooling process in a psychrometric chart.

Web we use our own portable evaporative cooling products to keep our manufacturing employees safe and comfortable for more than half the year! Web if you want to check this, you can calculate the relative humidity from the dew point and the outdoor temperature, and you can use that to look up the cooling potential of a swamp cooler on an evaporative cooler humidity chart. Web although specifications may vary by unit, most manufacturers recommend operating an evaporative cooler in an area where the temperature is above 80 degrees fahrenheit and below 60% humidity. The process is indicated in the psychrometric chart below. Air at with dry bulb temperature 70 of and relative moisture 60% (state a) is cooled down (state b) by evaporating water. Mold and mildew could become an issue. Web in general, evaporative coolers work best when the relative humidity is around 70 percent. Experiment by adjusting your windows to see which create the best breeze and how wide they need to. Web what is the ideal humidity for the evaporative air coolers to be the most efficient? Just find the intersection of temperature (on the right) and relative humidity (across the top) to the number on the grid where both measurements meet. If the humidity in the space is above 60%, it’s best to use a fan or a/c instead. Web the chart shows the effect of the relative humidity of the outside air on the temperature of the air that leaves the evaporative cooling system. In other words, an evaporative cooler makes the most sense, as we’ve noted, in dry air conditions usually found in desert regions. Web evaporative coolers are least effective in lower temperature (below 75°f) and high humidity (above 60% relative humidity) situations. Web you can get an idea of how much cooling can be expected in a particular environment by taking a look at the below graph which shows the temperature of the air blowing out of the fresair unit versus the outside air temperature, in various relative humidities.
Evaporative Coolers For Residential Use Work Best With The Dew Point Below 50°F.
The answer is it depends. Web evaporative cooler air temperature relative humidity chart. Web if you want to check this, you can calculate the relative humidity from the dew point and the outdoor temperature, and you can use that to look up the cooling potential of a swamp cooler on an evaporative cooler humidity chart. Web if you take a measurement of the air temperature and relative humidity in your town, you can use this chart to determine if you have optimal conditions to run an evaporative cooler.
To Better Understand What Temperature You Can Expect From Your Evaporative Cooler Depending On The Climate Where You Live, Use The Next Chart.
Web do evaporative coolers work in high humidity? 46″ l x 26″ w x 59″h. There are big differences between hot and arid climates like arizona versus hot and humid climates like florida. Web the chart shows the effect of the relative humidity of the outside air on the temperature of the air that leaves the evaporative cooling system.

For temperatures below 75°f and high humidity of over 60% relative humidity, evaporative coolers are. Air at with dry bulb temperature 70 of and relative moisture 60% (state a) is cooled down (state b) by evaporating water. Here’s an overview example of the heat/humidity with expected temperature drops from evaporative cooling: Experiment by adjusting your windows to see which create the best breeze and how wide they need to.
Perfect For Larger Patios And Workshops, The Model Mc61V Weighs 57 Lbs Empty And Measures 28” Wide By 46” Tall.
However, they can still be somewhat useful in the more humid climates of the south and midwest, working effectively in fan mode to circulate air throughout a building. The process is indicated in the psychrometric chart below. Web according to this swamp cooler chart, at 80 degrees f at 80% relative humidity, you can drop the temperature 3 degrees. Web in conditions of high temperatures such as 85°f or greater, and low humidity of below 50% relative humidity, evaporative coolers perform best.
