DuPont Refrigerants Unveils First DP-1 Refrigerant Test Car in Germany
29 November 2006
DuPont Refrigerants recently unveiled the first demonstration of its new, low global warming potential (GWP) refrigerant, DP-1, as part of its presentation at the recent European Automotive Air Conditioning (EAAC) Show in Frankfurt, Germany.
No changes were made to the demonstration vehicle’s existing MAC (Mobile Air Conditioning) system in order for DP-1 to run. Because it is compatible with existing technology, DP-1 has the potential to enable a cost-effective global transition to low GWP refrigerants across the entire global MAC industry, according to DuPont.
The auto industry is being pushed to adopt new solutions for mobile air conditioning. The EU has published the final regulation on the phaseout of HFC-134a from 2011-2017. The next-generation refrigerant must have a GWP of less than 150, and leak rate restrictions begin in 2008.
The US California Air Resources Board Climate Change has proposed the phaseout of HFC-134a from heavy equipment starting in 2010 and from cars starting in 2017. In the context of all of this, the auto industry wants a single global solution.
DP-1 is a two-component, non-flammable blend. The major component is a new non-flammable, fluorine-based compound. The minor component is a commercially available refrigerant.
According to DuPont, DP-1 offers properties and performance similar to that of R134a while featuring zero ODP (Ozone Depletion Potential) and a very low GWP estimated at 40.
