Sizing Instructions
The most accurate sizing is accomplished by the use of KoolKalk, our software
program, when you have already calculated the sensible cooling load of the
building. KoolKalk combines ASHRAE design day conditions, the principles of
psychrometrics, and hourly weather data of typical meteorological years for key
cities around the world. Contact your AdobeAir sales representative for a free
copy of KoolKalk, or see our website at www.AdobeAir.com.
Although not the preferred method, alternate sizing by considering only air
changes in the building may be adequate for some warehouse and other
industrial applications. To select a cooler or coolers based on air changes only,
follow these simple steps:
1) Determine the size (in cubic feet) of the space to be cooled (length x width
x height). Remember that in most cases a height of from 10-12 feet is all
that needs to be considered since that is typically only the height to which
cooling is required.
2) Determine how frequently the air needs to be changed in the building (minutes per air change) by referring to the chart and
map above. As an example, a warehouse in El Paso, Texas (zone 2) with an average interior heat load and exposed exterior
heat load needs an air change at least every 3 minutes as a rule of thumb.
3) Determine the total CFM required for the building by dividing the cubic feet of the space to be cooled by the number of
minutes for each air change.
Example:
Building size = 200' long x 100' wide x 12' height to be cooled = 240,000 cubic feet to be cooled.
Air needs to be changed every 3 minutes (El Paso, Texas example from #2 above)
240,000 / 3 = 80,000 cfm total delivered air required from coolers.
Select coolers delivering a combined total of 80,000 cfm.
