DuPont and Honeywell announce global joint agreement to develop new automotive refrigerants

Wilmington, Delaware – DuPont and Honeywell have announced a global joint agreement to accelerate the development and commercialization of next-generation, low global warming refrigerants for automotive air conditioning. The new refrigerants would enable automakers to meet new regulations in Europe that require the use of low global warming potential (GWP) refrigerants in mobile air conditioning regulations.

The new regulation is scheduled to take effect in 2011 for new model automobiles, with the transition complete by 2017. Currently, automotive systems use hydrofluorocarbon (HFC) 134a.

Under the agreement, the companies will jointly identify, develop, test and qualify new low GWP refrigerants that are cost-effective alternatives to other technologies being considered by the auto industry. Ideally, automakers are seeking a commercially viable fluorinated gas solution that is compatible with conventional HFC-134a mobile air conditioning system technology and offers a more cost-effective industry transition. The companies will work closely with the automotive industry to qualify a low GWP alternative by mid-2007.
