WebJun 28, 2024 · What does high subcooling and high super heat mean? If superheat is high and sub-cooling is high: Could have blockage in coil, orifice or line set. If superheat is low and sub-cooling is low: Orifice could be too big, there is no orifice in the unit of the orifice is stuck and refrigerant is by-passing it. WebJul 30, 2024 · Superheat can be measured as the difference between suction line temperature and evaporator temperature. A high superheat condition means that the evaporator is starving for refrigerant because it is boiling off too soon (before it can make it to the evaporator).

WebApr 5, 2016 · Superheat In order for superheating to occur, the opposite process of subcooling must take place. This is the act of applying heat to a substance that is already at its saturation point. As an example, water turns to steam at 212 degrees Fahrenheit. Applying heat to steam when the water is 212 degrees is superheating the steam.
