Test Results on New Refrigerant for Mobile Air-Conditioning Systems Released by SAE International

WARRENDALE, Pa., Dec. 8, 2008 - More information is now available on the new alternative refrigerant for mobile air-conditioning systems -- HFO1234yf – judged by the SAE International Cooperative Research Program (CRP) to offer significant environmental benefits.

The results from the CRP 1234-1 and CRP 1234-2 programs that investigated the safety and performance of the new refrigerant for use in mobile air-conditioning systems (including those used in cars and light trucks) are available on-line at http://www.sae.org/standardsdev/tsb/cooperative/altrefrig.htm .

Of all the proposed alternatives considered, HFO1234yf has significant environmental benefits compared with current refrigerants, and additionally poses no significant safety concerns, thus offering the greatest potential to meet environmental and consumer needs. 

The research, conducted by Gradient Corporation (USA), Exponent Engineering and Scientific Consulting (USA), Ineris, Institute National del'Environnement Industriel et des Risques (France), TNO Pharma (The Netherlands), Underwriters Laboratories (USA) and WIL Research Laboratories (USA), DNV Climate Services (Japan), did not identify any significant risks (including toxicology, flammability, etc.) for use of HFO1234yf in mobile air-conditioning systems.

Major automobile manufacturers from Europe, Asia and the United States, which together account for approximately 70 percent of all new-vehicle sales in the European Union as well as worldwide, have reviewed the findings of these studies.
