[EnergyPlus_Support] Re: Inserting Fan:ZoneExhaust into AFN zone
Dear Group,
I have split my roof detailed areas so that each fan:zoneexhaust is on its
own surface with own crack surface and properties defined. Still I get the
same error.
I have uploaded my actual file with revised objects, to the help desk...but for the rest of you there's a snip bit below.
I have included following AFN things:
- seperate BuildingSurface:Detailed objects for the fan roof penetrations
- seperate AirflowNetwork:MultiZone:Surface for each fan roof penetration
- seperate AirflowNetwork:MultiZone:ExternalNode nodes for each fan
- seperate AirflowNetwork:MultiZone:Component:ZoneExhaustFan for each fan
- new AirflowNetwork:MultiZone:Surface:EffectiveLeakageArea
- new AirflowNetwork:MultiZone:WindPressureCoefficientValues
- new AirflowNetwork:MultiZone:ReferenceCrackConditions
