Hanon Systems Estimates TFA Levels Generated by Automotive F-Gas Emissions

Hanon Systems [https://www.hanonsystems.com/En], a major South Korean provider of automotive thermal management systems, has released a report estimating the amount of trifluoroacetic acid (TFA) generated in Europe by emissions of refrigerants HFC-134a and HFO-1234yf from car cooling and heating systems. The report also describes the opportunity to limit TFA creation via the use of CO2 (R744) and propane (R290) as alternative refrigerants.
