Re: [EnergyPlus_Support] Need help to define Airflow Network




The model already has "Natural Ventilation", "Evaporative Cooling" & "Chillers"; so I may not be able to use non-AFN objects you suggested.
But, as I might be able to approximate the things by making 2 runs (one with AFN and other with Zone:Mixing).
Thanks jeannieboef. Your response helped.

Suggest you use the non-AFN objects such as zonemixing and infiltration and or zone ventilation objects, whilst switching the AFN off. When AFN is simulated these more basic objects are off. So you can easily switch back and forth and compare.

Check out the example files if you are new at building AFNs. Start with a simple 2 zone model to practice.

Dear Energyplus users,

I need help in defining the airflow network in energyplus as per the attached schematic.

I have one big "air-conditioned" zone and I want the ventilation air to pass through adjacent unconditioned zones. 

Right now I want the quantity of air flow (from conditioned to unconditioned zone) to be controlled & have a definite value.

If I could make it, I would further like to model the air flow due to pressure differences while there are some openings between conditioned & unconditioned zones.

regards,
Prashant
