The building uses a split unit heating/cooling system, with a completely separate dedicated outdoor air system for fresh air. The fresh air supply is constant and does not vary with the heating and cooling load. The split unit draws air directly from each zone (recirculating indoor air only) and is not at all connected to the supply ducting of the fresh air. I need to know how to model the split unit “heating plant” as the split unit will be running in the reversed cycle mode (heat pump) to provide winter heating to the guest rooms?<o:p></o:p></span></p><p class=MsoNormal style='margin-bottom:0in;margin-bottom:.0001pt;line-height:normal'><span style='color:black'><o:p> </o:p></span></p><p class=MsoNormal style='margin-bottom:0in;margin-bottom:.0001pt;line-height:normal'><span style='color:black'>Thanks,<o:p></o:p></span></p><p class=MsoNormal style='margin-bottom:0in;margin-bottom:.0001pt;line-height:normal'><span style='color:#1F497D'>Amgad Khattab, LEED AP<o:p></o:p></span></p><p class=MsoNormal style='margin-bottom:0in;margin-bottom:.0001pt;line-height:normal'><span style='color:black'><o:p> </o:p></span></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
