Defining an Always-Open Entrance Exposed to Outdoor Conditions

edit

Thanks @JasonGlazer for your response Could you possibly provide a more in-depth explanation? My knowledge of EnergyPlus is limited.

Here's what I've tried so far: I set up a very thin door construction for the entrance using the Material:NoMass object, with a thermal resistance of 0.00385 m2.K/W. However, it seems like this setup isn't quite realistic since it doesn't account for infiltration, given that the entrance is exposed to outdoor conditions.

Forget the idea that the "entrance" is an interior room of the building and instead define the building perimeter to go inwards at that point.

Thanks for the response! Just to clarify, I might not have explained the issue clearly.

I am modeling a refrigerated warehouse that is composed of 13 zones, 12 walk-in coolers, and a loading zone. The loading zone has an entrance that is always open (see figure above).

Sorry for any confusion.

I am currently doing some refrigerated warehouse modeling. Have you tried looking at the RefrigeratedWarehouse example model in E+? Below are comments from the IDF.

! Refrigeration load is highly dependent upon infiltration rates (ACH). Air chillers ! and refrigeration systems oversized to allow possible increase above rates used here. ! An effective Air Barrier System has been assumed in selecting the rates modeled here. ! A common InfiltrationSchedule has been used for all zones with adjustments for ! likely use made using the ZoneInfiltration:DesignFlowRate objects.

How about the AirFlowNetwork (AFN) model?

According to the EnergyPlus documentation, AFN is an advanced model designed to compute natural infiltration influenced by wind and forced air.

Can AFN be utilized to simulate infiltration through entrances?

I've looked into some EnergyPlus examples, but navigating them is challenging given my limited understanding of EnergyPlus. It's frustrating that explanatory documentation for the examples isn't available.
