This turns it into a boiling gas. 0000047436 00000 n Cambridge University Press, Cambridge, United Kingdom and New York, NY, USA. The canisters they come in cause a huge level of unnecessary waste, which is why the industry has regulations on these. The solution that would allow CFCs to be phased out is HydroChloroFluoroCarbons, also known as HCFCs. While there are plans to phase it out soon, many modern air conditioners are being built to use R410A as part of their cooling system. :68B6I"?uKF48R`r58j}s-Bjp :DOt=dDCq9gq?X{Z1VX#15-Tns)5o# U 0000004533 00000 n Some HCFCs are assumed to be similar in terms of Atmospheric Lifetime.
