To use our two examples from the previous paragraph, R134a at 0 psig and -5 F has 10 degrees of superheat, and the same refrigerant at the same pressure but at -20 F has 5 degrees of subcooling. These concepts of saturation, superheat, and subcooling are the foundation of all sealed system troubleshooting.Apr 22, 2024 · The liquid line temperature is 88 ° F. Subtracting the two numbers gives 36 ° F. High superheat and high subcooling indicates a problem with the metering device. Keep in mind that subcooling won't increase on systems with a liquid line receiver, as extra liquid will fill the receiver instead of backing up in the condenser. High subcooling shows that the condensing point is occuring earlier in the condenser while low subcooling shows that the condensing point is later in the condenser. Subcooling is used to charge systems with a TXV. Now you can see why knowing what, and why, superheat and subcooling are essential to proper diagnostics and troubleshooting.The Difference Between Superheat and Subcooling Comparing Subcooling and Superheat Subcooling – Cooling the Liquid Refrigerant.
