Opteon™ XP40 (R-449A) refrigerant

Opteon™ XP40 (R-449A) is a non-ozone depleting, low global warming potential (GWP) hydrofluoro-olefin (HFO) based refrigerant replacement for R-404A/R-507, R-407A/F, and R-22 for new equipment and retrofit of existing systems. Opteon™ XP40 has a GWP of 1282, which is a 67% reduction, and provides energy consumption 8-12% lower than R-404A/R-507. Compared to R-407A, Opteon™ XP40 offers improved performance, similar capacity and 33% lower GWP.

Properties

What to Expect After a Retrofit

The data below was obtained from a display case/condensing unit converted to Opteon™ XP40 from R-404A with only adjustments to the TXV (1.5 turns closed) during low- and medium-temperature operation at two ambient conditions per ASHRAE Standard 72-2005.

Note that actual performance for a specific system depends on a number of factors, including equipment conditions and operating environment.
