High Superheat High Subcooling: Only 2 Possible Causes + Fixes · Low refrigerant charge (undercharged system). · Restriction in the liquid line (usually ice).

1. a) Most walk-in coolers and freezers use a TX valve to regulate the flow of refrigerant into the evaporator. If the superheat is low the TX valve will allow refrigerant to flow into the evaporator at a rate that exceeds the capacity of the evaporator and as a result liquid will enter the suction line.Since both superheat and subcooling are changes in temperature, they are both sensible heat processes. When an air conditioning system cools air, sensible heat has been removed.
