Ratings are net; they account for the effects of the evaporatorfan motor power and heat.2. Direct interpolation is permissible. Do not extrapolate.3. The following formulas may be used:Example: 15.0 kW (at 240v) heater on 208v= 15.0 (.75 mult factor)= 11.25 capacity at 208vSensible capacity (Btuh)1.10 x cfmt ldb = t edb --Wet--- bulb temperature corresponding to enthalpyair leaving evaporator coil ( hlwb)t lwb =total capacity (Btuh)4.5 x cfmhlwb = hewb ---Where: hewb = Enthalpy of air entering evaporator coil4. The SHC is based on 80_F (26.6_C) edb temperature of airentering evaporator coil. Below 80_F (26.6_C) edb, subtract (corrfactor x cfm) from SHC.Above 805F (26.6_C) edb, add (corr factor x cfm) to SHC.Correction Factor = 1.10 x (1 + BF) x (edb + 80).5. Integrated capacity is maximum (instantaneous) capacity less theeffect of frost on the outdoor coil and the heat required to defrost it.50XL
