In TRNSYS 18 there are two options for modeling air handlers. You can build-up the air handler component by component using individual models for each component. There are also two VAV component models that can be used to model VAV air handlers. Please check out the HVAC templates for the ASHRAE90.1 systems in the TRNSYS/Examples/HVACTemplates folder for examples.

Hi Tim, thank you for your feedback.
I have a student license for Trnsys 17 and in the TRNSYS/Examples/HVAC folder there is no 'Templates' folder only 'HVAC-building', could you please transfer me these templates you referred to?
Regarding the VAV components I was using Type 648 for the air mix and Type 646 for the air zone diverter; are these the same Type you are mentioned?
Thanks for your help!
The VAV components and templates are only available with TRNSYS 18.
ok, so it is not possible to do this with Trnsys 17?
Of course you can model it in TRNSYS 17. You just don't have access to the specific VAV components or templates that come with TRNSYS 18. You will need to build your air handler model component by component just like you would build any other simulation in TRNSYS. Writing the controls equations will likely be the hardest part of the process.
OK, thank you. I am doing as you described, modelling component by component.
