A malfunctioning tool can result in refrigerant flow ...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.The less refrigerant flowing through the system, the less the suction line of the system will cool off. You can have a warm suction line (high superheat) due to low charge, a restriction, or high airflow. This indicator is one of many that you need to consider when diagnosing refrigerant problems. Looking at the pinched hose example, we can see ...

In the last Contracting …It doesn’t necessarily mean “really cold” — only “below saturation”. Conversely, the right side of the dome is the vapor side. A refrigerant plotted directly on that right line is at saturation and fully vapor. If it moves to the right, then it becomes superheated. So “superheated” refers to refrigerant anywhere to the right of ...

Subcooling. Subcooling is the temperature below the condensing temperature of a substance.
