Hello everyone,
I'm sorry for doing this but I have a really novice question. I recently moved from a cooling only climate location to the US. Now I'm working with both cooling and heating systems. I have a doubt when calculating fan external static pressure for dual duct systems. Do I assume that in the worst case scenario all the airflow will be travelling through only one of the decks (e.g. summer or winter) or do I assume flow on both decks at any one point? I'm calculating the ESP from existing drawings so I don't have load calcs to know the peak load of the building, just what I'm seeing in the schedules and floor plans.
Thanks for any help you might provide.
