[EnergyPlus_Support] How does Airflow Network really work?





Hello all,


It seems that Airflow Network has some things that "Cannot Do or Restricted".

For example, IOReferece says specifically:

"The model is restricted to using a constant volume fan (Fan:ConstantVolume and Fan:OnOff) and cannot model variable volume fan equipment." 


However, it seems that AirflowNetwork:Distribution:Component:Fan admits a Variable Fan.


Is IOReference outdated?


Also, what happens if you define an AirLoopHVAC but do not "connect" its definition to the AirflowNetwork (e.g. you define a Fan:VariableVolume but don't define the corresponding AirflowNetwork:Distribution:Component:Fan)


Or if you use IdealLoads systems, which do not have any connection to the Airflow Network definition?


What aspects from the HVAC systems are considered somehow in the Airflow Network simulation and which are not?


I think this is not clear in E+ reference.


Regards,


Germán Campos
