WebSubcooling can be caused by a low airflow or a filthy evaporator. Subcooling can be reduced by a dirty condenser. Subcooling will be reduced if an orifice is too large (and vice versa). You must use liquid pressure rather than discharge pressure to properly calculate subcooling. What happens to the compressor when the superheat is too low? WebLow 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.
