[TRNSYS-users] Connection between two or more air-nodes

[ITF - Adrien JEZEQUEL]

Hi Wirich

I think you haven't defined the airflow between zone. Trnbuild allows 
you to evaluate thermal behaviour, not airflows.
If you want to take into account airflow between zones, you have to 
define them.
You can use Comis or Contam (which are free) or Trnflow (not free) to 
evaluate airflows between zones.
You will find example on how to use Contam and Comis in Trnsys directory.

Best regards
