The first thing you need to figure out is the emitting load from these compressors. And then add that to the building load. After this you can now see how much heat needs to be dissipated in order to maintain the correct room temperature.
You mentioned about the ambient air temp. can be 120...
KGBaker,
Could you be more clear on the application? From your posting it appears that your bringing in outside air thru a gooseneck on the roof? Is this the case?
Kpha,
Maybe I could help? Do you know what the U factors that these rigs are made of?(walls, roof, floor) Where will this be located? What is the square foot of this rig? And finally, is there any internal heat gaining equip. inside?
I know it seems like alot but this is whats needed to...
The 4.2 cfm per sq. ft. of glass is for the solar load only. All other additional loads will have to be added too.
Is this what you were asking krismatt?
We never install ductwork to a unit or any other device with a motor without a flex canvas connection. Noise and vibrations are a nightmare. Why not just do it right the first time?
