Superheat and Subcooling are determined by the boiling temperature of the substance and unlike water many substances have low boiling temperatures. Recalling that latent heat is the heat which is added to a liquid to cause it to change from a liquid to a gas (boiling) without a change in temperature, let’s go to the next step. ...Low subcooling and high superheat are both conditions that can occur in a refrigeration system and indicate a problem with the system’s balance. Low subcooling means that there is an insufficient amount of refrigerant in the condenser, which is the part of the system where the refrigerant releases the heat it has absorbed from the evaporator.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.Subcooling (R-134A) = 88°F – 82°F = 6°F.
