Europe brought up a question of a ban of sale of Mercedes
Э the kspertny committee of 28 European Union countries recommended European Commissions to forbid sale in Europe of new Mercedes A and B-classes, reports ITAR-TASS. Justification: Germans fill the "wrong" coolant in conditioners of these models. Earlier the European Commission demanded from all automakers since January 1, 2013 to pass to use of a coolant of HFO 1234yf (2,3,3,3-tetraftorpropen) which is less harmful to environment, than such widespread coolant, as R134а (1,1,1,2-tetraftoretan).
Conditioners in cars started to mount in the first half of the 1930th in the USA. Foreign firms were engaged in it, it was some kind of tuning. The first brand which has offered for the models the conditioner as an option, there was Packard. There was it at the end of 1939. The main part of system occupied a luggage carrier half (the compressor stood, of course, in a motor compartment) and was ineffective, but the beginning was necessary (in pictures the Packard Super Eight model of 1940 of release). Similar experiences were put by Cadillac firm in 1941. But distributions did not receive these early systems.
Though R134а freon absolutely slightly influences an ozone layer in comparison with the coolants used in conditioners even before, at substance of HFO 1234yf the so-called potential of global warming is lower, than at R134а in 335 times. Alas, round so remarkable connection scandal inflamed. In December of last year the Daimler company carried out tests and found out that тетрафторпропен turns into the real fiery sphere, costs to it only in a mix with oil for the compressor of the conditioner to get on hot details of the engine. Ignition occurred more than in sixty five percent of modelled head-on collisions. And burning of a mix was accompanied by allocation of poisonous gas, besides with high corrosion properties.
After some break in the forties the modern history of automobile conditioners was opened by the Chrysler Custom Imperial 1953 model of modeling year. On it own Airtemp conditioner was already quite normal factory option. Imperial slightly outstripped rivals of other American brands at whom the optional conditioner appeared in the same 1953.
The Daimler company refused to use in conditioners new progressive structure before carrying out more detailed researches as safety of people in failures it is obvious more important than an ozone layer. The European Commission should discuss together with the German authorities (they are responsible for performance by the German companies of instructions of the European Union) how to arrive with the recommendation of Daimler of rather new experiments. If the understanding is not found, Mercedes are threatened by a ban on realization. Meanwhile since July of this year France «» imposed a temporary ban on registration of new Mercedes on anticipation just because of old freon.
