R22 subcooling chart - Here is a table with these causes that will help us understand why we get low superheat normal subcooling: Low Superheat Causes: Non-Normal Subcooling Causes (High Or Low): Indoor airflow (CFMs) is too low. Oversized AC unit. Outdoor airflow is too low (or condenser coils heat exchange is impeded). High refrigerant charge (overcharged AC unit).

 
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. . Arian brotherhoods tattoos
