[Equest-users] AHU supply & return fan air flow

[Liu, Xing]

Hi everyone,

Now I am trying to change the AHU air flow values in my model due to the changes in the equipment schedule. The problem is that I have made lots of modifications under the detailed mode, the last thing I want to do is to redo it again so I really don't want to switch back to the wizard mode to change the numbers. I can locate where the AHU supply fan air flow is in detailed mode but I cannot find out where is the return fan air flow. The other issue is I gave two different return fan air flow values in my previous projects, it seems the return air flow has no influence on the whole building energy usage which is different from what I thought. Any suggestions?

Your input is highly appreciated!  Thanks in advance.
