[Paul Diglio]

Hi:

Does anyone have the link that Steven mentioned?

Thank you,

Paul Diglio

Vikram,
 
Reid Hart of PECI did a
presentation on this issue for the building simulation user's group a few
months ago, and discussed a spreadsheet tool to construct accurate DOE2
performance curves for variable flow air and water systems.  I believe the
powerpoint presentation is still archived on the BSUG yahoo site, and the
spreadsheet is downloadable from PECI's website.  I haven't tried using this
tool yet, so I cannot vouch for its accuracy or useability.

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
