Summary

Air conditioning manufacturers are changing to R32 refrigerant due to its zero ozone depletion, lower Global Warming Potential (GWP) compared to HFC 410A, superior energy efficiency, and high refrigeration capacity. R32 is classified as "mildly flammable" or "lower flammability" according to International Standard ISO 817:2014, with a burning velocity of 6.7 cm/s and a heat of combustion of 9.5 MJ/kg. The risk of ignition is low, requiring a concentration between 14% and 29% volume, a velocity lower than 3-4 times its burning velocity, and an ignition source of sufficient energy. Even if ignited, the flame propagation is limited by characteristics such as quenching distance. Despite its classification as "extremely flammable" on the Material Safety Data Sheet (MSDS), the risk of ignition and flame propagation is relatively low.
