Independent Government Test Data

An independent U.S. government testing laboratory tested the Coolerado Cooler, and the results are available for viewing in PDF format by clicking the links at the bottom of this page.
 

About the Test and Data

The test was conducted on one of Coolerado's 200-cubic-feet-per-minute prototype coolers. Three different supply air temperatures with two absolute humidity levels were tested.

There is a psychrometric chart for each of the two absolute humidity conditions. The psychrometric charts plot the air data for:

• Three supply inlet conditions: the air coming into the cooler

• Three supply outlet conditions: the output or product air

• Three exhaust outlet conditions: the rejected, hot, moist air

It is amazing to see the cooling that is achieved (supply outlet), but be sure to note the condition of the rejected air (exhaust outlet). The rejected air is at, or very near the saturation line! The Coolerado Cooler is not only a very efficient cooler, but it is also a very efficient saturator.

Two additional graphs summarize the wet bulb effectiveness and dew point effectiveness for each of the six air conditions tested.

Conversions

Absolute humidity:  Divide grains by 7,000 to obtain lbs/lbs or kg/kg.

So:  21 grains = 0.003 lbs/lb    84 grains = 0.012 lbs/lb

Temperature: Multiply C by 9/5 and add 32 to get °F

So:  10°C = 50°F    20°C = 68°F    30°C = 86°F

40°C = 104°F     50°C = 122°F
