Re: [EnergyPlus_Support] Modelling interzone air exchange with AirflowNetwork





If you only care about zone cross mixing, there are zone:crossmixing and zone:mixing objects available.

Hi


I'm trying to model the interzone airflow with AFN


I used AfrflowNetwork:MultiZone:Component:SimpleOpening with one door object(FenestrationSurface:Detailed), and very simple geometry(only 2 zones in model).


However, when I run the E+ simulation, there is fatal error : 


** Severe  ** GetAirflowNetworkInput: No External Nodes found in AirflowNetwork:Multizone:ExternalNode. There must be at least 1 external node defined.


I can solve this error by just adding simple crack on roof surface with external AFN nodes definition, but in this way, there is unwanted infiltration AFN node air flow rate occurs. 


I just want to model the air flow networks through internal openings(door, window, ...) only.


Any suggestion?
