Basically, superheat is the temperature a refrigerant vapor needs to maintain its gaseous state as it passes through the evaporator coil. While subcooling is the additional cooling that takes place in a condenser after the refrigerant has already been condensed.At a high level, superheat occurs when you heat vapor above its boiling point. Subcooling occurs when you cool a vapor below the temperature at which it turns into a liquid. But let’s dive in deeper, starting with superheat. Boiling is when a liquid gains heat and transforms into a vapor. Remember, superheat occurs when you heat vapor above ... This presentation explains the sub-cooling and superheat charging charts and how they are used to determine system refrigerant charge.Determining superheat and subcooling The process for determining super-heat or subcooling is exactly the It is important to recognize which kind of PT chart you have before using it to troubleshoot a system.

Assessing System Efficiency. System Maintenance and Optimization. Adjusting Refrigerant Charge. Evaluating Expansion Valve Performance. Balancing System Capacity.Higher subcooling indicates excess refrigerant backing up in the condenser. On TXV systems with high superheat, be sure to check the subcooling as refrigerant is added. If the superheat doesn't change, and the subcooling increases, the problem is with the metering device. In the case of a TXV, it's likely that the powerhead needs to be replaced. Superheat is a condition where the vapor is warmer than the saturated temperature at a given pressure, so by definition, saturation is zero superheat. Unfortunately, when a system is at 0 degrees of superheat, liquid is present but there is no way to know how much. Compressors cannot compress liquid, so it is Target Superheat and Subcooling Heed all equipment manufacturer’s specifica-tions, warnings and suggestions above anything found in this manual. To determine the target superheat (fixed orifice system) or subcooling (charts vary dramatically from one system to another), you need the manu-facturers target superheat chart or subcooling chart. Step 3. Subtract the evaporator saturation temperature from the thermocouple temperature. This difference is the system superheat. This shows the temperature rise above the bubble point temperature of the system. Review the operating specifications for your system to determine the proper superheat. Inadequate superheat can cause liquid ...
