This presentation explains the sub-cooling and superheat charging charts and how they are used to determine system refrigerant charge.

Thus, to ensure the cooling capacity of the refrigerant is fully utilized, the liquid refrigerant will undergo subcooling. The subcooling process acts as a safety margin to ensure 100% capacity utilization. In addition, notice that the gradient of the compression process in the above diagram is not as steep as the one in the ideal PH diagram.How do you fix subcooling? If you think your HVAC system is subcooling, you should contact a professional to have it checked out. They will be able to diagnose the problem and recommend a solution. Subcooling chart.
