R22 Pressure: R22 operates at lower pressures compared to 410A. This means systems designed for R22 cannot handle the higher pressure of 410A without modifications. 410A Pressure: 410A operates at a higher pressure, leading to more efficient cooling cycles. However, this requires stronger, more robust components in the AC system.404R pressure temperature chart is quite simple to understand. This is a table that tells you precisely what the pressure of R404A is at a certain temperature. At the low end, the pressure of 404A is 0.9 psig. At the high end, the pressure of 404A is 456.8 psig. We are, of course, talking about 404A liquid pressure. TEMPERATURE - PRESSURE CHART FOR R-22, R-410A, R-407C, R-134A & R-404A REFRIGERANTS FYI #289 9/17/2009. updated 10/10/2012.

Let’s use the target superheat formula and calculate this manually: Target Superheat (R-410A) = (3 × 69°F – 80°F – 105°F) / 2 = 11.0°F. We see that the target superheat for R-410A refrigerant in this system is 11°F. You can use the target superheat calculator above to get to this result much quicker.The R-410A has about 40 percent less heat-carrying capacity than the R-22. This causes the reduction of the replacement between the two different compressors. If an R-22 compressor has R-410A refrigerant put into the system, the motors will overload and burn out. The overloading can also cause the motor to start tripping the breaker, shutting ...

If you are checking the charge then you need to check it by Sub-cooling (TXV) or Super heat (Piston). If you are doing it any other way you are just guessing. The are to many variables to say what should the reading be with an outside temp of 80. R22 has a very similar boiling point to R290 (-41.4°F to 44°F; that’s only a 2.6°F difference). 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. The compound gauge at left is used on the low pressure side of the system and shows pressure readings in black, from 0 to 300 psi gauge pressure.
