Bhp — Brake Horsepower edb — Entering Dry Bulb

2. Conversion — Bhp to watts:

ewb — Entering Wet Bulb

Watts =

Bhp x 746

NOTES:

1.Fan performance is based on wet coils, economizer, roof curb, cabinet losses, and clean 2-in. filters.

Motor efficiency

3.Variable air volume units will operate down to 70 cfm/ton. Performance at 70 cfm/ton is limited to unloaded operation and may be additionally limited by edb and ewb conditions.
