Refrigerant (R-1234yf)

Product Information

Opteon™ XL10 (R-1234yf) is a mildly flammable
refrigerant with global warming potential (GWP) less than
1 for replacement of R-134a in new equipment designs.
Opteon™ XL10 is a low GWP hydrofluoro-olefin (HFO) based
refrigerant with the optimal balance of properties to replace
R-134a in positive displacement, direct expansion medium
temperature commercial and industrial applications.

Benefits• < 1 GWP ( >99 % reduction versus R-134a) ; meets1)

F-Gas and Eco-Design GWP requirements; zero ozone
depletion• Close performance match to R-134a in terms of capacityand efficiency• Easily convertible from R-134a design with minimalchanges

Opteon™ XL10 offers similar performance to the refrigerants it
is designed to replace which makes it easy and cost-effective
to apply in new equipment without major modifications.
Classified as mildly flammable (ISO/ASHRAE Class 2L),
Opteon™ XL10 allows much higher charge sizes than othermore highly flammable refrigerants and can be safely usedby following the applicable codes and standards. With aGWP of less than 1, Opteon™ XL10 falls not only under the• Single component, no temperature glide• Non-toxic and mildly flammable (ISO/ASHRAE A2L)
• Allows >1.7 kg minimum filling charge under new Codes &2)Standards (e.g. ISO 5149 or EN 378)

• Miscible & stable with POE lubricantsOpteon™ XL10 properties

What to expect at similar operating conditions
The data below was obtained from theoretical cycle calculations for high temperature (0 °C mean evaporating temperature)and medium temperature (-10 °C mean evaporating temperature) refrigeration scenarios. For both the high and medium
temperature scenarios the following parameters were used: evaporator superheat = 4 K, suction line superheat 8 K, Liquid
subcooling 2 K and compressor efficiency = 70 %. 3)
