[EnergyPlus_Support] Anomalous results with ** Warning ** GetAirPathData: & ** Warning ** WetBulb [1 Attachment]




Hi all,

I'm testing an air heating system on a minimodel.
I created it with DesignBuilder and in DB I obtained an apparently correct internal temperature vs time.
Than I explorted the idf and I processed the idf (no modified, of course) with E+. The zone mean air temperature now is completely different and in my opinion completely out of mind.

The heating system just takes the air from the outside and heat the flux  untill 18°c if the air temperature is lower than this value. 

In particular I have 2 suspicious warnings, they are:

   ************* Beginning System Sizing Calculations
   ** Warning ** GetAirPathData: AirLoopHVAC="AIR LOOP" has no Controllers.

and

   ************* Beginning Simulation
   ** Warning ** WetBulb not converged after 101 iterations(PsyTwbFnTdbWPb)
   **   ~~~   **  Routine=Unknown, Environment=UNTITLED, at Simulation time=03/28 15:00 - 15:06
   **   ~~~   **  Input Temperature = 18.50
   **   ~~~   **  Input Humidity Ratio= 0.141212
   **   ~~~   **  Input Pressure = 99122.00
   **   ~~~   **  Resultant Temperature= 25.44

Thanks,
Marco
