[EnergyPlus_Support] RoomAir Node Temperatures in Mundt Model

["coutinho301272" <coutinho@xxxxxxxxx>]

Hello,
I am sizing a cooling system for a 7m tall industrial building by 
simply using a purchased air system and the Mundt model for a 
displacement ventilation air pattern. I am finding that the return air 
temperature (Mundt RoomAir Model Air Node Temp) and the Zone Mean Air 
Temperature are always about the same, i.e., close to the value of the 
Coling Setpoint Temperature, despite the air temperature near the floor 
being slightly above the Cooling Supply Air Temperature (T~20 C).
Could anyone help me in understanding this? Perhaps I am 
misundestanding the Setpoint Temperature... 
I guess that this result could be explained if the Termometer that 
controls the HVAC system is located at the return air node. Comments?

Many thanks in advance.
José
