Direct interpolation is permissible. Do not extrapolate. CFM — Cubic Ft per Minute 4. SHC is based on 80° F db temperature of air entering coil. EWB — Entering Wet Bulb (° F) Below 80° F db, subtract (Correction Factor x CFM) SHG — Gross Sensible Capacity 1000 Btuh from SHC. Above 80° F db, add (Correction Factor x CFM) to SHC TCG — Gross Cooling Capacity 1000 Btuh 5. All data points are based on 10° F superheat leaving coil. SHC CORRECTION FACTOR NOTES: 1. Contact manufacturer for cooling capacities at conditions other than shown in table. 2. Formulas: sensible heat cap. Leaving db = entering db — 1.09 x CFM Leaving wb = wb corresponding to enthalpy of air leaving coil (hlwb) Interpolation is permissible. total capacity (Btuh) Correction Factor = 1.09 x (1 – BF) x (db – 80) hlwb = hewb — 4.5 x CFM where hewb = enthalpy of air entering coil.
