Due to its environmental impact, R134a, the refrigerant currently used in vehicles around the world, is being phased out. To comply with new U.S. legislation, a new refrigerant, R-1234yf, is being introduced in its place. While it is an efficient refrigerant, R134a is also known to have consequences for global warming. Increasing environmental awareness has led the scientific and industrial community to search for a less harmful alternative. Starting in 2012, a range of vehicles with air conditioning systems running on the new R-1234yf gas will enter the U.S. market. however, the great majority of vehicles on the roads will still be using the older R-134a refrigerant – and these will continue to require servicing for the next 15 years or so. This means that your workshop will need equipment that can handle both the old and new vehicles.
R-1234yf has now emerged as the best possible replacement. This gas has an environmental impact of 4 gwp (units of global warming potential) – well under the Eu limit of 150 gwp, and a major improvement on R134a, which has a whopping 1430 gwp. what’s more, R-1234yf does not have hefty cost implications for industry.
The only downside of the new refrigerant, compared to R134a, is that it can be flammable in specific circumstances. however, this can be kept under control with well-engineered air conditioning servicing machines – like our Robinair units – and some common sense precautions in the workshop./p>
