Refrig-Superheat and Subcooling Charging Methods Cylinders Most R-410A cylinders have an internal dip tube which allows the feeding of liquid when the cylinder is in an upright position. They must be inverted for for vapor flow. Color is rose (pink).Normal evaporator superheats: The TXV will try to maintain superheat even at an excessive overcharge. As mentioned above, the TXV may overfeed slightly during its opening strokes, but then should catch up to itself if still within its operating ranges. High compression ratios: The condenser flooded with liquid during the overcharge will run high …

Follow heat as it moves through the system to see if the system is or is not performing as it should. That means understanding and measuring all three types of superheat: evaporator, total, and duct system. 1. Evaporator superheat.
