The German car industry has stopped all developments on new refrigerants, planning to simply not comply with a EU law banning the current fluid R134a from 2011 on, according to the German NGO Deutsche Umwelthilfe. Germany’s leading TV channel ARD will focus on this issue today.
Don't get too excited just yet about 1234yf. TFA and HF issues will prove to be fatal for this chemical (even if the chemical guys are doing their best to have people not think about them).
I believe that you may have missed the point of the article above. OEMs are stopping work on all next generation refrigerants and are deliberately going against the 2011 MAC directive. They are hoping that the European Commission will do nothing. That way that can keep using 134a and the discussions, meetings and development work we've had for the last 10/15 years will have been of no use.
Regarding 1234yf, ask yourself, why is that the only guys advocating for 1234yf (besides the chemical companies themselves) are a consultant and an increasingly lonely EPA official. I challenge you to find a Press Release from an OEM in favor of 1234yf.
Too bad too sad. I had planned to buy German instead of Amerirican because of the Dorchland's auto makers forward thinking. I suppose I'll be looking accross the other pond for my next truck.
Tbc,
thanks for your reaction. My reaction was-- it was too good to be true with CO2 --.but -- Chemicalia is much cleverer than we think and right so, they have billions of dollars to loose in this game and will do anything possible to avoid CO2 to become the preferred refrigerant fluid in European Mac systems. The whole aftermarket in MAC service is totally against CO2 as far as new investments is concerned. Although R1234yf may be 10 xs more expensive as R134a and be just as bad for it’s toxicity of TFA & HF important is that it also complies with the new EU Regulation of a maximum Global Warming Potential of 130 figure. Extremely important for the manufacturing industry is that old R134a systems can be easily adopted to R1234yf at extreme profits for the aftermarket industry. Third world can change over without any problem and here comes the beauty of it all. You can also retrofit to HC’s without any problem Australia and USA have given us the examples, so far we have approx 4.5 million MAC systems running with HC’s and never have lost a tort case so far. (see Dr I.L.Maclaine-cross paper on hydrocarbon21.com with the title-- Usage & Risk of Hydrocarbon Refrigerant in motorcars for Australia & the United States). This is a peer reviewed paper Published by the IIR France. The HC solution is extremely important ( environmentally) for the third world and will also be important for the first world aftermarket ( be it with extreme difficulties ) both R1234yf and HC are flammable but 4.5 million MAC systems with HC’s and millions of user years in the field have proven that HC’s is exactly the answer to the MAC system pollution problems. I regret all the work done on CO2 systems but if the manufacturing industry is starting to quarrel over –Only New Models need the new fluids—than the EU made a mistake in the Regulation and the Auto/Car Industry is looking for a way out.
I would like to hear other comments on this issue from Fellow Members. It’s important to discuss these issues.
