International. SAE International, the global association with more than 128,000 engineers and experts in the aerospace and automotive industries, said in its latest research that it found no problems in the use of R1234yf refrigerant for air conditioning in vehicles.
The latest International Cooperative Research Project (CRP) run by SAE says most of the manufacturers involved in the study do not believe that any new revised information will lead to a change in the overall risk assessment.
This is the fourth study of its kind, which this time was promoted by the German manufacturer Daimler after its rejection of the R1234yf, based on the tests it had carried out and which called into question the safety of the refrigerant in the event of a head-on collision.
According to SAE, many manufacturers shared results from their vehicles, and with the exception of Daimler, no other has submitted information that could suggest a concern for the safe use of R1234yf in their vehicles. It was previously concluded that this is a safe and acceptable alternative refrigerant for mobile air conditioning systems.
The new risk assessment and publication of results is expected to be completed in the second quarter of 2013. The team includes thirteen members: Audi, BMW, Chrysler/Fiat, Daimler, Ford, General Motors, Honda, Hyundai, Jaguar Land Rover, Mazda, PSA, Renault and Toyota.
