[Bldg-sim] [Equest-users] Fan-Pwr-fPLR-w/VFD

[John Forester]

James,

 

We've recently reviewed this topic and came up with information from the
DOE-2 help files that has a picture (Figure 37) that shows the fPLR curves
for the different fan control methods.  If you do a search for "FAN-CONTROL"
you should be able to find Figure 37 and do some take-offs to compare
baseline and proposed performances.  I've attached a screenshot of the DOE-2
help screen.  Hopefully it comes through for you.

Does anyone have the default curve data for this fan curve?

 

I've got a built-up AHU I'm modeling with a fan-wall configuration, and I
know that the EIR vs part load ratio should be better than the default VFD
fan curve.

 

But I can't seem to get  savings by defining a performance curve using the
100%, 90%, 80%, etc values.  It might help if I had the default values.

 

Thanks!
