<p class="MsoNormal">Hi everyone,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Can anyone help me assert or correct my understanding on something? This is from a model built in v3.65, b7175, doe2.2 engine (with intent to upconvert the project to doe2.3 before I’m done).<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Report PV-A lists the capacity for each heating/cooling loop. Here I’m cropping to just the loops, and highlighting what I’m used to thinking of as the “peak” coincident capacity requirement for a chilled water loop – 13.909 MMBtu/hr (that’s
millions):<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal" style="margin-left:.5in"><img width="925" height="384" style="width:9.6354in;height:4.0in" id="Picture_x0020_3" src="cid:image002.jpg@01D521E8.47C63900"><o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The following reports PS-H go into more detail on each item listed in PV-A. Here is the report for the same “Chilled Water Loop,” with a coule more highlights:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal" style="margin-left:.5in"><img width="845" height="898" style="width:8.802in;height:9.3541in" id="Picture_x0020_7" src="cid:image003.png@01D521E8.47C63900"><o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Immediately, I note that <b><span style="color:red">13.909 MMBtu/hr</span></b><span style="color:red"> (1,159 tons)
</span>aligns with PV-A, however I do not see that number matching (intuitively) any of the other figures or sums provided on this sheet. The figure
<span style="background:yellow;mso-highlight:yellow">5,625.126 kBtu/hr (469 tons)</span> aligns with my expectations for peak load on the loop, where nominal capacity of the associated chillers on this loop are in the same ballpark (one is 444 tons and one
is 210 tons on paper & @ design conditions, and I’m told they commonly do not need to engage the smaller chiller during the dead of summer).<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Can anyone help me reconcile the differences between what’s reported as “Cooling Capacity” in PV-A, in relation to the annual peak loads indicated for the same loop in the PS-H report?
<o:p></o:p></p>
