[Equest-users] More about fans

Same model - different fan question. Table G3.1.3.15 Gives you a part
load performance table for VAV fan systems. Based on that, I created a
performance curve (linear) for my VAV fan system that looks like this:

 

 

 

 

Problem is when I use this as opposed to  the default curve that came
out of the wizard, the fan energy doubles. The fan energy is still only
8% of the overall building load, so its not alarming. Does this mean
that the default curve was way to low? Is the method above the way to
model this performance curve?

 

Thanks for your help
