If you have two identical chillers, I am 99% certain they will behave exactly as you’ve described. That is, chiller A will handle the first 400 tons of load, then for hours with 401 tons and upwards the two chillers will share the load 50/50. The only nuance to add is that, again assuming they are identical, the chiller that is engaged first will be determined by the which occurs first in the .inp. </span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#002060"> </span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#002060">Best regards,</span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#002060"> </span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#002060">~Nick</span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#002060"> </span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#002060"> </span></p><div><p class="MsoNormal"><b><span style="font-size:14.0pt;font-family:"Calibri",sans-serif;color:#002060">NICK CATON, P.E.</span></b><span style="font-size:11.0pt;font-family:"Verdana",sans-serif;color:#1f497d"><br></span><b><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#561782">Owner</span></b></p><p class="MsoNormal"><b><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#561782"> </span></b></p><p class="MsoNormal"><b><span style="font-size:10.0pt;font-family:"Calibri",sans-serif;color:#561782">Caton Energy Consulting</span></b><span style="font-size:10.0pt;font-family:"Calibri",sans-serif;color:black"><br></span><span style="font-size:10.0pt;font-family:"Calibri",sans-serif;color:#1f497d"> 306 N Ferrel</span></p><p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Calibri",sans-serif;color:#1f497d"> Olathe, KS 66061</span></p><p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Calibri",sans-serif;color:#1f497d"> office: 785.410.3317</span></p><p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Calibri",sans-serif;color:#561782"><a href="www.catonenergy.com"><span style="color:#561782">www.catonenergy.com</span></a></span><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#002060"></span></p></div><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#002060"> </span></p><div><div style="border:none;border-top:solid #e1e1e1 1.0pt;padding:3.0pt 0in 0in 0in"><p class="MsoNormal"><b><span style="font-size:11.0pt;font-family:"Calibri",sans-serif">From:</span></b><span style="font-size:11.0pt;font-family:"Calibri",sans-serif"> Equest-users [mailto:<a href="mailto:equest-users-bounces@lists.onebuilding.org">equest-users-bounces@lists.onebuilding.org</a>] <b>On Behalf Of </b>Jones, Christopher<br><b>Sent:</b> Friday, August 21, 2015 7:49 AM<br><b>To:</b> 'Sambhav Tiwari'; equest-users<br><b>Subject:</b> Re: [Equest-users] Chiller sequencing</span></p></div></div><p class="MsoNormal"> </p><p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial",sans-serif;color:#1f497d">Sambhav,</span></p><p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial",sans-serif;color:#1f497d">I suggest reviewing the DOE22 Manuals.
