[TRNSYS-users] AHU Example with heat wheel and VRV system

[David BRADLEY]

Al-Hyari,

   It is not really possible to know what might be going wrong without 
running the project. What I would suggest is that you make a new project 
to which you add only the exhaust and outdoor air fans. Make sure they 
are the right size by adjusting parameter values and run the simulation 
using an online plotter to verify that the temperature, humidity and 
flow rate leaving the fans is as you planned for it to be. Next, add the 
heat wheel into the system. Again, make sure that the parameters are 
correctly set so that the heat wheel is appropriately sized to the 
application. Again, use the online plotter to verify that the 
temperatures, humidities, and flow rates exiting the wheel make sense. 
Keep adding one component at a time and verifying as you go.

   kind regards,

  David
