Recently, the reporter learned from relevant sources, U.S. Environmental Protection Agency on Feb. 28 approved a vehicle air conditioner refrigerant alternatives HFOs-1234yf (HFO1234yf), its global warming potential is only 4.

    It is understood widely used in automotive air conditioning on the HFC-134a, although not damage the ozone layer, but the global warming potential up to 1430. EPA pointed out that car manufacturers, to make cars and light trucks to achieve greenhouse gas emission standards, choose one HFC-134a than the global warming potential lower cost of refrigerant is is both a good and effective methods.

    The European Union banned from this year onwards HFC-134a refrigerant, require vehicle air conditioning refrigerants GWP must be less than 150. It is obvious that the new refrigerant to fully meet the needs of the European Union, this new type of vehicle air conditioner refrigerant alternative to HFCs olefin-1234yf (HFO1234yf) popular in Europe and America and even global market reach.
