Evaporative Cooler Efficiency Chart

Evaporative Cooler Efficiency Chart – The chart in figure 7 shows the supply air cooling temperatures that an aspen fiber evaporative cooler (about 70% effective) can provide at outdoor temperatures ranging. Direct cooling process in a psychrometric chart. T dbe = entering dry bulb temp t wbe = entering wet bulb temp t dbl = leaving dry. Understanding evaporative cooling performance requires an understanding of psychrometrics.

Learn how evaporative coolers work, how to size and install them, and how to maintain them. The process is indicated in. It is simple to predict cooler performance from standard weather report information. Η = efficiency in percent.

Evaporative Cooler Efficiency Chart

96°f and humidity 35% results in an. This chart shows that as indoor air temperature rises, an evaporative cooler will become more effective at cooling air as the relative humidity drops. Evaporative cooling performance is variable due to changes in external temperature and humidity level.

You can look up the maximum cooling any evaporative cooler can provide for any given temperature and humidity on an evaporative cooler humidity chart, such. 4) evaporative cooling performance factors: See a chart of the efficiency.

How to read the chart if you take a measurement of the air temperature and relative humidity in your town, you can use this chart to determine. A secondary heat exchanger is used to prevent humidity from being added to the airstream that enters. Across the cooling media is 27ºf (as in the above example), the cooling efficiency is 90%.
