I Show Where the Measurements are Taken, Tips to Help You...Subcooling is beneficial because it prevents the liquid refrigerant from changing to a gas before it gets to the evaporator. Pressure drops in the liquid piping and vertical risers can reduce the refrigerant pressure to the point where it will boil or "flash" in the liquid line. This change of phase causes the refrigerant to absorb heat before ...Unfortunately, there is a lot of misunderstanding as to what exactly Superheat and Subcool actually are and even less understanding on how to measure it. There are so many novice technicians that get ‘stumped’ on a system without even checking Subcool or Superheat temperatures…. or if they did check them they checked in the wrong section.
