How does the example of AFN in LBT1.3 work?

I think I should move this issue here, I’m trying to make the Earth Tube working in LTB 1.3 Honeybee Earth Tube component is ready to fly! - #6 by chris

and for other Airflow example, like Evaporative_Cooling_Tower, Vented_Double-Skin_Facade, and ThermalChimney, what I’m trying to do is,

  1. update the file to Honeybee Legacy new version
  2. try to re-model them to LBT 1.3 if it’s possible

But I still can not make sure the difference between “Group – Airflow Network” and “Group – Airflow”

Does it mean, I can only use one of them in Honeybee? Which has priority if I model them both in Honeybee because of my mistake? Or I just get a chaos?
