<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">If you select a boiler TYPE of “…w/ draft” you will see default values for the boiler ELEC-INPUT-RATIO and EIR-FPLR curve. This simulates electrical consumption
coincident with boiler operation. You could calculate an EIR based on all fan power, controls etc. associated with your boilers. I haven’t plotted the default “Draft-Fan-EIR-fPLR” curve so you might take a look at it and make changes based on your particular
boiler plant.<o:p></o:p></span></p>

<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto"> <o:p></o:p></p>
<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">I’ve been using eQuest on a basic to moderate level for a while, and am starting to get into more detailed modeling.<o:p></o:p></p>
<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto"> <o:p></o:p></p>
<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">What I have now is a building with boilers in a basement that get fresh air from a 100% OA supply fan. The fan is interlocked with the boilers so that it only supplies air when
the boilers are burning fuel. The fan also has a hot water coil to keep the air at a minimum temperature to prevent thermal shock of the boilers.<o:p></o:p></p>
<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto"> <o:p></o:p></p>
<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">I’m pretty sure I’ve got the heating figured out, but how do I link the fan schedule to the boiler operation schedule?<o:p></o:p></p>
<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">An answer to this will definitely help in figuring out interlocking other equipment in eQuest<o:p></o:p></p>
