Air Handler #1 - AHU-1 Or 2 - Total Load Summary Air Handler Description: AHU-1 Or 2 Constant Volume - Sum of PeaksSupply Air Fan: Draw-Thru with program estimated horsepower of 2.40 HPFan Input: 65% motor and fan efficiency with 1.2 in. water across the fanSensible Heat Ratio: 0.99 --- This system occurs 1 time(s) in the building. ---

Because of the diversity in zone, plenum and ventilation loads, the zone sensible peak time in July at 7pm is different from the total system peak time, hence the air system CFM was computed using a zone sensible load of 153,158.

Summer: Ventilation controls outside air, ----- Winter: Ventilation controls outside air.

Because of the diversity in zone, plenum and ventilation loads, the zone sensible peak time in July at 7pm is different from the total system peak time, hence the air system CFM was computed using a zone sensible load of 157,268.
