Example 2: Target Superheat Calculation (This calculation will get you close to manufacturer superheat chart results) WB is 64° F, DB is 96° F. Target Superheat Formula = [ (3 x WB) – 80 – DB] /2. [ (3 x 64) – 80 – 96] /2 = Target Superheat. 3 x 64=192, 192-80=112, 112-96=16 16/2=8° F of Target Superheat. 8° F of Target Superheat.
