Step 12. Compare the super-heat reading to the gauge's psi reading. If the super-heat reading is more than 20 degrees above the P/T chart's reading, then add R-22 until the super-heating reading reaches the optimal range -- between 8- and 18-degree super-heat, depending on the environmental conditions. Many technicians charge the system until ...

2. Then take the suction pressure and convert it to temperature on a temperature/pressure chart. Subtract the two numbers to get superheat. For example, 68 psi suction pressure on a R-22 system converts to 40°F. Let's say the suction line temperature is 50°F. Subtracting the two numbers gives us 10°F of superheat.

R407c is an HFC refrigerant that will replace the R22 refrigerant, as per Montreal Protocol. It is a mixture of R32 (23%), R125 (25%), and R134a (52%) that has a boiling point of -46.84°F. The same as R22, due to useful pressure-temperature properties, R407c is used in air conditioning systems, cars, and refrigeration units. Below, you will ...

TXV’s control the superheat. You can, however, check the superheat to see if the TXV is working properly. To Determine Sub-Cooling: 1. Take the high side pressure and convert it to temperature using chart or gauge. 2.Superheat and subcooling. How do you find superheat? Measure the suction line temperature and suction pressure at the suction side service valve. Ensure the temperature probe is insulated from any external influences. Convert the gauge pressure to saturation temperature and subtract this temperature from the suction line temperature.Table 2 (continued) Freon™ 22 Superheated Vapor — Constant Pressure Tables V = Volume in m3/kg H = Enthalpy in kJ/kg S = Entropy in kJ/kg·K Saturation Properties in ( )In determining a Target Superheat cross referencing the indoor wet bulb and outdoor dry bulb temperatures, the charging chart will recommend the proper Target Superheat for …Overall Process: Enter refrigerant, temps, and pressures The math is done for you; superheat calculations, subcooling calculations, and airflow calculations all display Target, Actual, and Difference Repeat steps 1-2 until all HVAC Diagnostics check out as "Okay"; send system status report VIA text message or email as needed

Many units have a charging chart, behind the name plate on the condensing unit, use this first. Charge by superheat for fixed metering devices, and use subcooling for TXV’s, if your not sure check the manufacturer documentation.According to the R-22 PT chart, this is equal to about 54°F. With the thermometer, we measured the saturated R-22 temperature of 45°F. Here is how we can calculate the R-22 superheat in this system: Superheat (R-22) = 54°F – 45°F = 9°F. The superheat calculator also gives us 9°F superheat for R-22 refrigerant.May 14, 2014 · But if you take a charging chart and plug in the numbers, it comes out the same. +/- a cou [ple of degrees. example: Carrier R22 chart wet bulb 66 condenser 90 required Sh 13 @70 psi suction. 3 x 66=198 198-80= 118 118 - 90=28 28/2 =14 sh Don't know why but it works. Doug. At 100°F, however, the pressure of R22 is 195.9 psig and the pressure of R290 has a pressure of 174.3 psig (check the R290 PT chart below). This is a 20+ psig difference and you will easily tell if you have an R290 or R22 freon.
