<p class=MsoNormal>Does anyone have the default curve data for this fan curve?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>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.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>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.<o:p></o:p></p>
