CFC-12, the amount of vapor superheat at a point in the suction line to the compressor (point D) is calculated from the saturated vapor temperature. Freon™ Refrigerants THERMOSTATICOn a standard split system, the superheat should be maintained between 8–12°F of superheat.In other words, a higher superheat means a lower percentage of the coil is being fed with saturated (boiling) refrigerant. The higher the % of the coil being fed, the higher the capacity of the system and the higher the efficiency of the coil. This is why we often “set the charge” using superheat once all other parameters are properly set ...R-404A, R-407C, R-408A, R-409A, R-410A, R-422D, and R-507 are based on vapor free 100°F liquid refrigerant enter-ing the expansion valve, a maximum opening superheat of 7°F, and a standard factory air test superheat setting.
