R1234yf, the refrigerant jointly developed by Honeywell and Dupont that is being phased in as a replacement for R134a in Europe, is safe. So says a panel of scientists from the Joint Research Council, researching the refrigerant at the request of the European Commission. German automaker Daimler, though, disagrees with the finding, saying R1234yf can be toxic to humans when burned, according to Automotive News.
On this episode of As the A/C Refrigerant Turns, the KBA, Germany's motor authority, has released its findings on the refrigerant r1234yf. The joint venture of Honeywell and Dupont, r1234yf has pitted Daimler against France and Germany against the EU; Daimler refused to use the new refrigerant, saying it's more dangerous to occupants in a crash, so France refused to register Mercedes-Benz cars that used to old, non-EU-approved refrigerant. The latest step was France taking steps to formally ban
That didn't take long. Shortly after a French administrative court gave the French government a ten-day window to reconsider its ban on registrations of Mercedes-Benz A-, B- and CLA-Class cars using the prohibited R134a refrigerant, the government cited an EU directive to formalize banning the sale of the cars. The country's environmental ministry said that registrations "will remain forbidden in France as long as the company does not to conform to European regulations," meaning so long as they
The brief alphanumerics R134a and R1234yf are codes for a growing battle between carmakers, states and the EU. The air-conditioning refrigerant R134a has been banned by the EU for being too damaging to the environment, with R1234yf mandated as its replacement. Daimler and Volkswagen say that in their own studies, though, R1234yf can be more dangerous in an accident, potentially starting fires and releasing poisonous hydrogen fluoride gas.
The last time we checked in on the battle of refrigerants, France had enacted a registration ban on some Mercedes-Benz vehicles because their air-conditioning systems were loaded with R134a, which was found to be harmful to the environment by EU tests. Now, other EU states are considering banning the substance, according to Automotive News, as they push for a new refrigerant, R1234yf, to be used in new vehicles across the board.
About ten months ago, we reported on Daimler AG and Mercedes-Benz raising warning alarms about a newly approved refrigerant for automotive air conditioning applications, called R1234yf. The new coolant was approved for use in the European Union because it has a reduced negative effect as a greenhouse gas when compared with its precursor, R134a. However, Daimler and VW contended that the new coolant posed a serious risk in crash situations, where it could not only pose a primary fire risk, it mig
