R22 suction and discharge pressure chart
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.Forane 407C Pressure Temperature Chart Forane 407C, R-407C, Pressure Temperature Chart, PT Chart, HVAC, refrigeration, air conditioning, refrigerant gas

For example, a high-efficiency condensing unit using R-22 typically operates with a suction pressure of about 68 psi and a discharge pressure of about 250 psi at an outdoor temperature of 95°F. Is R12 a low pressure refrigerant? Registered. R12 should run about 30-35 psi suction for auto AC.Efficiency Ratio (EER) is similar to that of R-22. Discharge pressure is only slightly higher and suction pressure is only slightly lower than R-22, so in most cases, existing system pressure settings can be used. While the existing Thermal Expansion Valve (TEV) sizing and power head can be used with R-438A, the slightly lower suction We would like to show you a description here but the site won’t allow us.R22 retrofit HFCs.
