For 3-stories office building, 13200sqft each floor, in West Virginia.
This is the first time I do HVAC design, I have no experience. My supervisor wants to choose single package rooftop gas heating/electric cooling units.
He wants to use 3 units for 3 floors( about 30tons, 20tons, 25tons) , all of them are put on the roof. Do you think this is a proper design scheme?
Also, I can't find on the catalog of BRYANT the pressure(Pa) the supply fan can supply. It only shows the HP.
I really appreciate your advice. Thank you.
