Photo 1: Measure superheat and subcooling together to “see” the refrigerant state in the evaporator and condenser. You can “see” the refrigerant state in both the evaporator and condenser. I misdiagnosed a lot of systems when I tried to shortcut and look at only one of these measurements based on the type of metering device.

Attach the Manifold Gauges. Connect the manifold gauges to the low-pressure port. Ensure it is attached securely to prevent any leakages and to get accurate readings. Take Temperature and Pressure Readings. Using a thermometer, take the temperature reading of the suction line — this is the line that carries the refrigerant back to the unit. Superheat and subcooling are the two fundamental concepts in any HVAC system. 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.Bryan with HVAC School goes over AC pressures, subcooling, and superheat in his troubleshooting mindset presentation from the BTrained HVAC training event in Birmingham, AL.

Superheat Versus Subcooling. Superheat and subcooling serve different purposes in HVAC systems. While superheat focuses on the evaporator side, ensuring that all liquid refrigerant boils off before reaching the compressor, subcooling deals with the condenser side, making sure that refrigerant loses enough heat after condensation.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.the superheat constant. Subcooling involves two measurements as well: one for pressure and one for temperature, but this one is taken from the liquid line. Target subcooling can be found on the system nameplate. The actual subcooling should be within ±3°F of the target subcooling for correct refrigerant charge. An improper …As we will see in the R-22 and R-410A examples at the end, target superheat for a system using R-22 and the target superheat for a system using R-410A (or any other refrigerant) are the same.

If we put all of these causes in a neat table, we can quickly see what is causing high superheat and high subcooling in air conditioning units: Low refrigerant charge (undercharged system). Restriction in the liquid line (usually ice). Indoor airflow (CFMs) is too high. Indoor heat load is too high. Learn how to calculate superheat and subcooling values for different refrigerants and HVAC systems. Find out why these measurements are important for proper refrigerant charge, diagnosis …By taking superheat and subcooling measurements. SUPERHEAT Superheat is the amount of heat added to a dry vapor, in the absence of liquid, to raise the vapor temperature above its boiling point (saturation point) corresponding to the pressure at which it is operating.
