This free online tool allows HVAC professionals to quickly calculate Superheat and Subcooling measurements for both R22 & R410A refrigerants.

If the actual subcooling is higher than the target subcooling, the unit’s refrigerant charge level is overcharged. Some refrigerant will need to be recovered into a recovery bottle. • Actual Subcooling +/-3° F Target Subcooling = Correct Refrigerant Level. • Actual Subcooling < Target Subcooling = Add Refrigerant.If the superheat is too low, you risk flooding the compressor. Subcooling (SC) Subcooling is another method to improve the efficiency of the refrigeration cycle. We can define subcooling as the difference between the condensation temperature and the temperature at the inlet of the expansion valve.3. Calculate superheat: Subtract the saturation temperature from the suction line temperature (Suction Line Temperature – Saturation Temperature = Superheat). Example: If you have a suction line temperature of 65°F (18.3°C) and saturation temperature at 45°F (7.2°C), the superheat calculation will be as follows: 65°F – 45°F = 20°F ...3. Restriction of the Liquid Line. Water line blockage disrupts refrigerant systems, reducing cooling efficiency and increasing energy use. Solution. The solution involves discharging excess refrigerant, but it’s vital to confirm its presence, as impairment in the metering device may also cause high subcooling.Superheat temperature measurement points. temperature. This is the temp-erature of the refrigerant when the last of the liquid has boiled into a vapor. Any vapor tempera-ture increase above the dewpoint temperature is called superheat. (See Figure 2.)

In this video I do not go into the details of superheat and subco...Superheat = Current Temperature – Boiling Point. Superheat is measured by its temperature above its boiling point. If a refrigerant vapor boiling point is 140 degrees, for example, then anything about that pressure would be too high for that specific refrigerant. To calculate the measurement of subcooling, the formula is: Subcooling = …

How to Check Subcooling. Attach the thermometer to the liquid line. This time, near the condenser. Then take the head pressure in Psi and convert it to the temperature on the pressure/temperature chart. Assuming you are dealing with a R22 system, let’s say the head pressure is 260Psi. This will convert to 120F.Subcooling is beneficial because it prevents the liquid refrigerant from changing to a gas before it gets to the evaporator. Pressure drops in the liquid piping and vertical risers can reduce the refrigerant pressure to the point where it will boil or "flash" in the liquid line. This change of phase causes the refrigerant to absorb heat before ...SuperheatCalc—SuperheatCalc is a free app in the Apple App Store and Google Play, enables HVAC service technicians to calculate target superheat for systems using fixed-orifice expansion devices, superheat and subcooling for 26 refrigerants, and airflow and psychrometric calculations to aid with field service of HVAC&R equipment.The app was a …SuperheatCalc—SuperheatCalc is a free app in the Apple App Store and Google Play, enables HVAC service technicians to calculate target superheat for systems using fixed-orifice expansion devices, superheat and subcooling for 26 refrigerants, and airflow and psychrometric calculations to aid with field service of HVAC&R equipment.The app was a …I come back the next day expecting to have to pull charge out and the subcool being way high.
