Here in America our phase out began in 2010 and the refrigerant will be completely phased out in 2020. Taking R-22’s place is the HFC refrigerant blend known as R-410A, our Puron. As I write this article, in 2019, there are still thousands of R-22 machines out there, but they …

An R410a and R22 charging calculator or the "Non TXV Charging Guide" are required to determine the target total superheat. Because these systems do not "control superheat" it is critical that the airflow be as close to possible to correct prior to charging as the system will be charged to the airflow.SUPERHEAT To determine subcooling for R-401A, R-404A, R-407A, R-407F, and R-408A, use BUBBLE POINT (temperatures above 50°F) To determine superheat for R-401A, R-404A, R-407A, R-407F, and R-408A, use DEW POINT values (temperatures 50°F and below) Pressure (psig) • Vacuum (Inches of Hg) - Italic Figures Form 1A / 82012 Practical Applications of the Subcooling Chart 410a.
