According to the power point presentation on the subject, it should be modelled as PVVT with separate system for each zone. In this case what values would you use? Would it be the same as my original model or is there a way to define values with different proportions based on the initial ones?<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Wouldn’t it make more sense to design 4 PVVT as many as the VRF I have? And in this case which is the zone controlling the system? If I ‘m not wrong, eQUEST only allows to choose one.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>And one more general question: eQUEST creates by default plenum for each space and HVAC systems with all zones.
