  • Dupont and Honeywell to Produce Eco-friendly Refrigerant2009-04-10
  • The global warming issue has led the auto industry to take steps to reduce the emission of greenhouse gases into the atmosphere. Newer technologies have led to the reduction of carbon dioxide emission on new cars. Particulate filters and other related components makes sure that the carbon dioxide formed by burning petroleum products in an internal combustion engine will be purified before being shot out of the vehicle's tailpipe.

    But aside from a vehicle's internal combustion engine, it also poses a threat to the environment due to the refrigerants they use on automobile cooling units. To reduce this threat, two giant companies have formed a partnership to develop an eco-friendly refrigerant that can be used on automotive air conditioners.

    DuPont and Honeywell recently announced that they have formed an agreement that will see them sharing resources, investment and technology to produce the future of vehicle refrigerants. The partnership aims to develop a refrigerant that will help car manufacturers meet stricter European legislations concerning the threat of refrigerants to the environment. Currently, automobile air conditioning systems uses HCF-134a. The said refrigerant poses a serious threat to the environment because of its high global warming potential.

    The partnership is geared towards the developing of new refrigerants which will have a significantly lower global warming potential. They are also looking at the cost effectiveness of the new refrigerant that they are aiming to produce.

    Currently, the auto industry is already considering new technologies but is held back by their cost. That is the reason why DuPont and Honeywell are aiming to develop a refrigerant that will cost less than alternative technologies. One of the more famous alternative refrigerant technologies is the use of carbon dioxide. Using that technology though would mean significant costs in transition so DuPont and Honeywell look to develop a refrigerant that is fluorine-based which is well-matched to the HFC-134a technology currently being used.

    Terrence Hahn, the Vice President and General Manager for Fluorine Products at Honeywell, have this to say about their aim: "Honeywell has a proven track record of developing refrigerant technologies to meet industry and customer requirements. We look forward to providing a near drop-in replacement that reduces the need for costly system redesign for the automotive industry. For the consumer, we will provide an environmentally friendlier, low-GWP solution without sacrificing comfort or reliability."

    DuPont's Vice President and General Manager for DuPont Fluoroproducts Cynthia C. Green have this to say: "DuPont science and innovation helped ease the transition from chlorofluorocarbons to alternative products for both industry and society. Now we are quickly responding to the global automotive industry's request for new refrigerants with lower global warming potential that offer a strong balance of benefits for safety, performance and cost-effectiveness. By leveraging DuPont and Honeywell resources, we can expedite product qualification and commercialization to provide a new global industry solution in time to meet regulations and effect an accelerated reduction in greenhouse gas emissions around the world."

    The development of a new refrigerant that will be developed by the partnership will surely be a good step forward for the auto industry. Initiatives such as this shows the way forward in the battle against global warming just like a Nissan light which shows the way ahead for drivers.
