[EnergyPlus_Support] Re: Temperature Stratification in a zone

["Jean marais" <jeannieboef@xxxxxxxxx>]

Check out the different RoomAirModel in the ioref.

for example my last simulation...

RoomAirModelType,
Z1 3Node, !- Room-Air Model Name
  Z1_Main, !- Zone Name
    ThreeNodeDisplacementVentilation, !- Room-Air Modeling Type
    Direct; !- Air Temperature Coupling Strategy
  
  RoomAirSettings:ThreeNodeDisplacementVentilation,
    Z1_Main, !- Zone Name
    SCH_GAIN_DIST, !- Gain Distribution Schedule Name !A value of 1 means that all the convection
                                                      !gains from equipment, task lights and people are dispersed in the lower occupied subzone.
                                                      !Conversely a value of 0 puts all the lower subzone convective gains into the plumes rising
                                                      !into the upper well-mixed subzone
    5, !- Number of Plumes per Occupant               ...1 CnC operator + 3 servo drives + 1 control cabinet = 5
    1, !- Thermostat Height                           !
    1.1, !- Comfort Height                            !Seated height
    .3; !- Temp. Difference Threshold for Displacement Ventilation
