Re: [EnergyPlus_Support] Vertical Stack to induce natural ventilation

[Lixing Gu <gu@xxxxxxxxxxxx>]

Ooi:

The Airflow Network model is not a good model to simulate natural 
ventilation in a vertical stack. The main reason is that the model does not 
have a component to deal with large horizontal openings accurately for the 
time being.

However, you may try it with following suggestions using the AirflowNetwork 
model:

1    Create one or more zones for a vertical stack
2    Create a zone you would like to ventilate
3    Use a component (AirflowNetwork:Multizone:Component Detailed Opening) 
to connect the vetilated zone and the vertical stack zone.
4    If you create more vertical stack zones, use the same compoent to 
connect two vertical stack zones. One way flow will be obtained from 
horizontal openings.
5    Follow rules of the AirflowNetwork model to create a network. See 
references to get detailed information.

Please let me know what happens.
