COOLING CAPACITY REQUIREO-BTU/HR
INSTRUCTIONS:
1. Determine Ihe area lo be cooled In square feet and locale that
point on the left srde of chart
2. Move horizontally across to the center lrne of Band A, 0 or C
according to the condition of the cethng in the area to be cooled.
Band A-Occupied Space Above Ceding
