August 21, 2018. R-22 was the most popular refrigerant used in commercial and residential air conditioning units for many years because it was considered a safe and cost-efficient refrigerant choice by the HVACR industry. But as anyone in the industry knows, R-22 was phased out in the U.S. beginning in 2010 because it is ozone depleting.Suction Pressure/EVAP DTD Rule of Thumb Another common old-school rule of thumb is that suction pressure should be close to the outdoor temperature in an R22 system. However, this rule of thumb (obviously) does not work on an R-410A system. A more applicable guideline is 20°-25° suction saturation below outdoor ambient.Pressure Temperature Charts. °F. °C.
