Bhp Ð Brake Horsepower
NOTES:
1.Fan performance is based on wet coils, economizer, roof curb, cabinet losses, and clean
2.Conversion Ð Bhp to watts:
Bhp x 746
Watts =
Motor efficiency
3.Variable Air Volume units will operate down to 70 cfm/ton. Per- formance at 70 cfm/ton is limited to unloaded operation and may be additionally limited by edb (entering dry bulb) and ewb (enter- ing wet bulb) conditions.
