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.Freon™ NU-22B™ has an ASHRAE A1 classification and is non-ozone depleting and nonflammable. It is well-suited for AC applications because it closely mimics the operating characteristics of R-22 and works over the same operating pressures as R-22.

R-404A rose to prominence in the late 1990’s with the phasing out of CFC and HCFC refrigerants like R-12 and R-502. There had to be a replacement for the Ozone damaging refrigerants of the past and the successor was the HFC R-404A that we all know of today. 404A’s reign however was short lived.FreonTM MO99TM (R-438A) and FreonTM NU-22BTM (R-422B) Refrigerants Retrofit Guidelines Introduction, Safety, General Retrofit Procedure Introduction FreonTM MO99TM and FreonTM NU-22BTM refrigerants have proven to be reliable, cost-effective, non-ozone depleting retrofit refrigerants.
