Example: Suppose the evaporator outlet temperature is 100 degrees and its inlet is 90 degrees, calculate super heat. Therefore, the super heat is 10 degrees. Prev Article. Next Article. The clamp-on thermometer reads 77°F. Here is how we use the subcooling formula to manually calculate the subcooling in this system: Subcooling (R-22) = 89°F – 77°F = 12°F. We see that the calculated subcooling for R-22 refrigerant in this system is 12°F. This is the manual calculation. The best answer is—as usual—whatever the manufacturer says it should be. If you really NEED a general answer, you can generally expect: High Temp or A/C systems to run 6-14°F of superheat. Medium Temp – 5-10°F. Low Temp – 4-10°F. Some ice machines and other specialty refrigeration may be as low as 3°F of superheat.SUPERHEAT HVAC FORMULA.
