kW/cfm can change delta-T here enough to affect baseline system CFM, prompting you to re-calculate fan power… this gets old after a few rounds! Usually the difference in sized CFM is not major, but can be enough to make your baseline system calcs appear off
to an attentive reviewer. To avoid this crazy little merry-go-round, I typically lock the fan heat down by entering (red text) the value from which baseline sizing CFM’s are determined – i.e. the default. I do this after my sizing run and immediately prior
to entering my calculated kW/CFM inputs. There are other ‘fair’ ways to handle fan heat I’m aware of (motor placement –> “outside airstream” and zeroing out fan heat prior to your sizing run come to mind), but so far as I know ASHRAE is pretty silent on the
matter, so you may choose any path you would feel comfortable explaining to a reviewer.<o:p></o:p></span></p>
