Correct the airflow problem and check the charge again. When charging by the subcooling method, you should be sure to check the suction superheat as well. If the expansion valve goes bad, you can have a very low suction ...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.1. Low Refrigerant Charge (Low Subcooling) Or High Refrigerant Charge (High Subcooling) The most common cause for non-normal subcooling is a wrong refrigerant charge. If the system is overcharged (too much freon), we will get high subcooling. In the system is undercharged (low refrigerant charge), we will measure low subcooling.In this article, we will define both superheat and total superheat, calculate total superheat, explain how to use total superheat to check the refrigerant charge, and show where the measurement points are taken on an air conditioning system. Total Superheat Formula: Actual Vapor Line Temp – Sat Temp = Total Superheat.
