<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>We are modeling a displacement ventilation system in eQuest. 
Currently, the system is set up as a PVVT, with the return air path set to
plenum zones and an economizer with dual enthalpy outside air control.  We
have distributed some of the heat loads to the plenum zones in order to
simulate the stratification in a displacement ventilation system.  I am
wondering if the return air will be appropriately heated by the heat loads in
the plenum zone, and if this higher temperature return air will be
appropriately modeled by the dual enthalpy economizer.  Also, how would
you suggest diagnosing this to see if it is working correctly?<o:p></o:p></span></font></p>
