Greetings! I'm new to this forum but whenever I use Google to find engineering answers I find this forum.
I am recommending a face and bypass damper retrofit for a large (60,000 CFM) existing fan system with the intent of saving fan energy. I'm approaching this with the fan laws in hand and have original design static pressures available. I want to install one 2 foot tall damper section in the middle of three 2 foot tall coil sections and am trying to deduce a suitable SP reduction amount. My thinking is to use a number like 1/3 as a prediction (1/3 less SP). Does this sound reasonable? Does anyone have a better approach?
Thanks!
