On many newer systems, especially high-efficiency systems, thermostatic expansion valves (TXVs) are used. Expansion valve systems are normally charged by using the subcooling method. Liquid sub-cooling is required so that you have only liquid entering the expansion valve with no bubbles present.

High Superheats — High superheats also are caused by the evaporator and compressor being starved of refrigerant. With the TXV restricted, the evaporator will become inactive and run high superheat. This will cause the compressor superheat to be high. The 100 percent saturated vapor point in the evaporator will climb up the evaporator coil ...Normal Subcooling High Superheat.

Low subcool= not enough refrigerant in the condenser Compression ratio is fine, unlikely to be the valves. It isn’t possible for you to have liquid refrigerant in the liquid line if the line is hotter than the boiling point of the refrigerant. A Negative subcool number is not a thing.If superheat is low and sub-cooling is high: Charge must be adjusted. System overcharged 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. Jul 10, 2019 ...

High superheat, low subcooling—or high subcooling, low superheat—can tell us ...Subcooling is when the temperature of the refrigerant liquid is below the saturation temperature. This can happen at the beginning of the refrigeration cycle, when the system is first turned on, or if there’s a problem with the system. Subcooling is the difference between the saturation temperature and the actual liquid refrigerant temperature.Sep 30, 2009 · Faced with the choice between changing one's mind and proving that there is no need to do so, almost everybody gets busy on the proof.
