<p class="MsoNormal"><span style="color:#1F497D">We stopped using the eQUEST heat recovery chiller years ago because it’s not controlled properly. eQUEST exclusively dispatches the heat recovery chiller on cooling demand, and in a hospital the heating or the
cooling load may drive the heat recovery chiller. I never checked if v3.65 corrected this.

<p class="MsoNormal"><span style="color:#1F497D">We use TRNSYS 17 with hourly loads from eQUEST et al as it allows us to be more accurate/flexible on controls, and then submit an exceptional calculation for LEED/compliance.

<p class="MsoNormal"><span style="color:#1F497D">You can create your own spreadsheet do as it’s a pretty simple heat balance if the chilled and hot water temperatures are constant.

<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">Note, that the capacity and the efficiency of the heat recovery chiller changes with the chilled and hot water temperatures so if you’re resetting temperatures it will make the spreadsheet more complex.

<p class="MsoNormal">Hi Everyone,<o:p></o:p></p>
<p class="MsoNormal">I am working on a project where I have a heat recovery chiller that is recovering heat from IT room units in a hospital and then providing heat to VAV reheat systems for other spaces. I am trying to model this in equest and not getting
the desired result. <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">eQuest is not letting me connect to reheat loop. And when I connect it to my steam loop, I see no heating savings whereas I see increased cooling use.
<o:p></o:p></p>
<p class="MsoNormal">Anyone has any ideas on how to model this properly?<o:p></o:p></p>
