<p class="MsoNormal">Hi eQuesters, <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The next two questions have been asked on here multiple times, but I have scourged the list and haven’t found a resolution. My building is a school in New England.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have a DCV measure that shows an increase in cooling. My thought is that DCV is taking precedence over the economizer. Is there a way to force eQuest to have economizer priority or is there another issue going on?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The other issue is in the Heat Recovery. It also shows an increased cooling load for the building. I tried setting it on an ERV Schedule and limiting it to the heating season. I tried playing with the different controls. I know it’s not
due to the increase in fan energy needed since the majority of units already have ERVs, but the efficiencies are better than code (and I also tried messing with the fan energy). Someone on the bldg-sim list even suggested controlling the ERV with Exhaust DT
and increasing the delta-T to 20F. <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I couldn’t get any suggestions to work. How can I avoid overheating? Or is there another issue?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks in advance for any help you can give me.<o:p></o:p></p>
