Supply Air Fan: Draw-Thru with program estimated horsepower of 0.57 HP
Fan Input: 0% motor and fan efficiency with 0 in. water across the fan
Sensible Heat Ratio: 0.79 --- This system occurs 1 time(s) in the building. ---
Air System Peak Time: 5pm in August.
Outdoor Conditions: 94° DB, 78° WB, 120.06 grains
Because of the diversity in zone, plenum and ventilation loads, the zone sensible peak time in August at 6pm is different
from the total system peak time, hence the air system CFM was computed using a zone sensible load of 158,620.
