R22 subcooling chart
Example of how to fix a 3 ton 16 SEER AC unit running on R-22 freon that has high superheat and low subcooling: Add R-22 refrigerant (but only after you fix the leak, more below). To simplify this, we can say that: High Superheat = Amount of refrigerant in the evaporator coil is too low. Low Subcooling = Amount of refrigerant in the condenser ...Robo stated it clear, the normal superheat for a residential system can and will vary and some charts go even further than he stated 2-45 degrees. That answer above drives the point, if you do not know the evaporator load, you can not predict the superheat.

Here is a chart that contains low superheat causes and low subcooling causes: Indoor airflow (CFMs) is too low. Oversized AC unit. Outdoor airflow is too low (or condenser coils heat exchange is impeded). High refrigerant charge (overcharged AC unit). Metering device (TXV, AEV, or piston) is overfeeding.SuperCool Slide Rule. $19.99. Quantity. Add to Cart. PRODUCT INFO.

Word of Advice TV•330K ...A Practical Example of Superheat Subcooling Calculation. Consider an HVAC system with an actual refrigerant temperature of 75°F and a saturation temperature of 55°F. Using our calculator, we get a superheat of 20°F and a subcooling of -20°F. Applications of the Superheat Subcooling Calculator. a. Subcooling = 100°F – 92°F = 8°F. The calculation itself is the easy part. The harder part is how to measure the needed refrigerant temperatures for superheat and subcooling calculation. We use an HVAC manifold gauge and a clamp-on thermometer for all superheat and subcooling measurements.
nk1888 R-407C is a zeotropic blend of R-32 (Difluromethane), R-125, and R-134a (Tetrafluoroethane). It is not a drop in replacement on R-22 machines.
