Here&#8217;s the tree structure. It only shows one loop. I really question the
validity of what the Wizard is doing. So, I went into the detailed mode and
created another circulation loop and set it up the way I think it should be,
but if that is right, then the 100&#8217;s of Wizard set ups by modelers
everywhere are messed up, and I doubt that???? &nbsp;See the tree from the
detailed set up I did in the second image below. The problem with that one is I
can&#8217;t get the one coil load to get off the primary loop and I don&#8217;t
trust it, if it is so different than what the Wizard sets up.<o:p></o:p></span></font></p>

<p class=MsoNormal style='margin-left:1.0in'><font size=2 face="Times New Roman"><span
style='font-size:11.0pt'>When using the eQuest Wizard and a primary-secondary
chilled water pumping system is set up, I don&#8217;t see the secondary
circulation loop in the tree structure. Furthermore, per the DOE documentation,
the chillers would be assigned to the primary loop and the cooling loads
assigned to the secondary loop (DOE2 Topics Vol 2, p. 312-313), but the results
from the Wizard show in the tree structure everything assigned to the primary
loop, as does the output PV-A Plant Design Parameters report. In that report,
the chillers do show term called &nbsp;&#8220;(Run-around)&#8221; by their
evaporators. Is this supposed to be what we would normally call the primary
loop? Why aren&#8217;t there two circulation loops showing up in the tree
structure?<o:p></o:p></span></font></p>
