The heat recovery would be shown through the common water loop in this case. When modeling air-cooled VRV/VRF in IESVE, you setup a CHW loop with a part load chiller curve for the condensing unit. Then engage condenser heat recovery to an air-air heat pump model for heat recovery VRV/VRF. It turns out pretty well.<o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'><a href="http://www.daikinac.com/content/resources/software-tools/">http://www.daikinac.com/content/resources/software-tools/</a><o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p><div><p class=MsoNormal><b><span style='color:#1F497D'>Cory Duggin, PE, LEED AP BD+C <o:p></o:p></span></b></p><p class=MsoNormal><i><span style='font-size:10.0pt;color:#1F497D'>Associate/Energy Modeling Wizard, j.g.</span></i><i><span style='color:#1F497D'><o:p></o:p></span></i></p><p class=MsoNormal><i><span style='font-size:10.0pt;color:#333333'><img border=0 width=264 height=80 id="_x0000_i1027" src="cid:image001.jpg@01D0E4C9.DCF3D0B0" alt="GreenWeek2015_FINAL-Email-Sig"><o:p></o:p></span></i></p><p class=MsoNormal><b><span style='color:#006363'>TLC Engineering for Architecture </span></b><span style='font-size:12.0pt;font-family:"Times New Roman",serif;color:#1F497D'><o:p></o:p></span></p><table class=MsoNormalTable border=0 cellspacing=0 cellpadding=0><tr><td valign=bottom style='padding:0in 0in 0in 0in'><p class=MsoNormal align=right style='text-align:right'><span style='font-size:9.0pt;color:#333333'>direct: </span><span style='font-size:9.0pt;color:#555555'><o:p></o:p></span></p></td><td valign=bottom style='padding:0in 0in 0in 0in'><p class=MsoNormal><span style='font-size:10.0pt;color:#1F497D'>615-346-1939</span><span style='font-size:10.0pt;color:#1F497D'><o:p></o:p></span></p></td></tr></table><p class=MsoNormal><span style='font-size:10.0pt;color:#1F497D'><o:p> </o:p></span></p></div><p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p><div><div style='border:none;border-top:solid #E1E1E1 1.0pt;padding:3.0pt 0in 0in 0in'><p class=MsoNormal><b>From:</b> Shane Wells [mailto:shane@hpengineeringinc.com] <br><b>Sent:</b> Tuesday, September 01, 2015 2:59 PM<br><b>To:</b> Duggin, Cory <Cory.Duggin@tlc-eng.com>; bldg-sim@lists.onebuilding.org<br><b>Subject:</b> RE: Ground Source VRF with Energy Recovery<o:p></o:p></p></div></div><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><span style='color:#1F497D'>That was my thoughts for estimating this with trace – modifying the equipment curves.
