WebLow superheat normal subcooling can indicate that the refrigerant charging is high either due to plugged evaporator coils or due to plugged air filters. The reason for the normal subcooling despite the low superheat is because the refrigeration system is installed with a liquid line receiver. WebYou get superheat when you have 100% vapor, and you have subcooling when you have 100% liquid; any liquid-vapor mixtures are in a saturated state. We usually measure superheat outside at the suction or vapor line. It's best to take the superheat reading as close to the port as possible. charabanc imagesWebStudies had shown that the subcooling and superheating applications cause an increase of around 10% in the system performances. Plus, depending on the choice of refrigerants, an effective subcooling and superheating application causes a saving up of up to 10% in the energy consumption.
