‘Cool Refrigerant’ Meets Environmental, Consumer Needs


The Society of Automotive Engineers (SAE) International Cooperative Research Program, sponsored by major automotive manufacturers including Chrysler, Ford, General Motors, Fiat, Jaguar, Land Rover, Hyundai, PSA, Renault, and Toyota, recently released a report summarizing results of its industry evaluation of low global warming potential (GWP) refrigerant, hydrofluoro olefin (HFO)-1234yf, which was co-developed by DuPont. The report validated that HFO-1234yf is safe to use in mobile air conditioning, and that of all the proposed alternatives considered, HFO-1234yf has significant environmental benefits. The report concluded that HFO-1234yf offers “the greatest potential to meet environmental and consumer needs.”

“DuPont is pleased that SAE International and leading automotive manufacturers have recognized the benefits of HFO-1234yf,” said Cindy Green, vice president and general manager, DuPont Fluoroproducts. “HFO-1234yf has a dramatically lower global warming potential than the R-134a refrigerant used today, and the best overall lifecycle climate performance globally, which makes it the preferred environmental solution. Since it is a near drop-in replacement for R-134a, it is also a practical choice, keeping costs down for both automakers and consumers at a critical time.”

DuPont estimates the use of HFO-1234yf refrigerant in new cars has the potential to save more than 590 million gallons (about 2,200 million liters) of fuel annually – the equivalent of taking approximately 1.5 million cars off the road each year, based on equivalent cooling and energy performance and global adoption of HFO-1234yf by the year 2017.
