R1234yf or its profoundly more tongue-twisting proper chemistry name 2,3,3,3-tetrafluoropropene is replacing r134a (1,1,1,2-tetrafluouroethane), which replaced Freon-12 (dichlorodifluoromethae).
Anyhoo here’s the brief history of automotive refrigerants:
In the olden days they used freon-12 which was awesome as a refrigerant but might as well have been Sarin gas as far as the ozone layer was concerned. It was also a pretty good propellant for aerosol cans.
Developed countries basically ditched Freon-12 in 1996, and developing countries boned it in 2010.
The refrigerant in your car right now is probably the r134a that’s been in common use for about 20 years. It’s about the same as Freon 12 as a refrigerant, but its effect on the ozone layer is insignificant. It doesn’t burn in most environments, either, and it’s non-toxic.
But it is very bad for greenhouse. It’s like 1300 times worse than CO2 when you calculate the Global Warming Potential against standard protocols.
The new refrigerant – let’s just call it Twelve-34 – has a global warming potential less than 1.
Global Warming Potential for dummies – CO2 has a GWP of One. All other gasses are indexed in relation to that. Methane is 34. Nitrous oxide – one of the gasses that got the Monkey Spankers doing the whole Cool Hand Luke bit – is 298. Like that. The current refrigerant is pretty bad.
The new refrigerant – Twelve-34 – is more flammable than the current one, but Honeywell/DuPont, which makes the stuff, in China, says it is: “Very difficult to ignite with an electric spark.”
Mercedes-Benz disagrees. Probably because they’re arseholes who want to delay spending the big bucks on the new refrigerant.
But following up on the three-pointed swastika’s disagreement, the German Federal Motor Transport Authority (the KBA) did its own tests and concluded that Twelve-34 is more flammable than the current refrigerant but determined that Twelve-34:
“Poses no material risk to occupants.”
After three rounds of tests, the KBA found:
“No sufficient proof was found with the cars tested that would have hardened the suspicion of a serious danger as defined by the product safety law.”
Among carmakers, Benz seems to be a lone voice with its knickers in a twist over Twelve-34.
However, if Twelve-34 does burn, that’s bad – because A) cars are jam-packed with stuff that just loves to burn, and B) when Twelve-34 burns it decomposes into some rather bad shit that a sane person would opt not to breathe, given the choice…
…toxic, corrosive shit like hydrogen fluoride (which is, like, gagging to become hydrofluoric acid) and also something called carbonyl fluoride – which is almost phosgene gas, and almost as bad for you. So that’s nice.
But my take on this – with my engineer’s hat on – is this:
Petrol is some of the most dangerous stuff imaginable. And you are in closely-coupled systems with tremendous acquired energy – sharing that space with that dangerous stuff – every day.
Robust engineering is all that ensures the risk of catching fire is low – in both normal operation and in the aftermath of a collision. Except of course in a Ford. They don’t seem to give a crap about that, in opposition to the position taken by most other carmakers.
In the context of all that – I simply do not see this new refrigerant as a problem. And the benefit of Twelve-34 is crystal clear.
Like most automotive technology – the wide implementation of Twelve-34 is going to occur under the radar. Your air conditioning in your car is going to function exactly the same, and I doubt there will be any tangible increase in risk as a result.
