Reuters have reported U.S. supplier Honeywell’s joint venture with chemicals company DuPont to produce R1234yf refrigerant for car air conditioning systems may be anti-competitive, following a near-three year EU probe.
EU Directive 2006/40/EC or what’s known as the MAC Directive calls for the phase-out of current fluorinated greenhouses gases such as R134a. The current refrigerant HFC R134a does not meet this requirement. There are three possible refrigerants for the alternative automotive solution and to date; HFO-1234yf has proved to be globally the manufactures choice. This does not affect current production models which will continue to use R134a
