Additionally, it widely replaces HCFC R-22 which was ...Like R-22, R-410A is nonflammable, but can become combustible if mixed with air at elevated temperature and/or pressure. The required conditions depend on air concentration, pressure, and temperature. Do not mix R-410A with air for leak testing or other purposes. A mixture of R-410A and nitrogen can be used for leak testing.The approximate pressure of the R-410A storage cylinder at 80°F is 368 psig. Explanation: The pressure of a gas is directly proportional to its temperature, according to Charles's Law. Therefore, to determine the approximate pressure of the storage cylinder containing R-410A at 80°F, we need to know the pressure of the gas at a known temperature.What is YOUR policy for topping off a 410a system after the leak is fixed? A few years ago we were told to reclaim it all and recharge if the standing pressure didn't meet the PT chart within one degree. Any leak always showed a 8 degree difference from what it should be. ... And when we had out 3 days of above normal temps last year.

Find …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. If you wish to use this product you will need to vacate all of the old R-22 out of the system. This is due to the R-22 systems using mineral oil and this HFC blend using POE oil.
Because of this, pressure-based rules that work with R-22 do not work with R-410A. The good news is that R-410A's temperature glide is smaller than 0.2 degrees. System manufacturers agree that 410A behaves so similarly to R-22 in this respect, for small leaks, R-410A can be topped off.What is the low side and high side pressure for R410A? A typical R-22 system operating normally with a head pressure of 260 psig at a 120-degree condensing temperature and a low side pressure of 76 psig at a 45-degree evaporator saturation temperature will find the equivalent pressures in a R-410A system to be much higher.…
