I want to simulate the stack effect in a high room with high thermal gain.
For this, I have 1 zone and 5 thermal air nodes in the z direction to get the temperature at several heights.
--
How can I do this and avoid that TRNSYS see ceiling between the zone ? Do I need to delete the horizontal surface for zone 2-3-4 ? Or do I put mass less horizontal surface ?
As Well, how do I do the cross flow ventilation ? Do I use the couple mass flow between zones ?
or I put a coupling air flow (same that natural ventilation mass flow) for the horizontal surface ?
Thanks a lot.
