The European Commission has ended its antitrust investigation into cooperation between Honeywell and DuPont (now Chemours) on the production of refrigerant R1234yf.

The ban on the use of R134a in mobile air-conditioning systems within the EU has triggered a series of research projects. Apart from the CO₂ technology (page 35), new refrigerants with very low GWP values and similar thermodynamic properties as R134a have been developed.

Bitzer has become the first compressor manufacturer to approve a full range of new low GWP refrigerants.

DuPont has created an updated version of its DuPrex 4.0 refrigerant comparison software to mark the sales launch of its new Opteon product range.

Refrigerant manufacturer DuPont expects to see the low GWP R1234yf replacement in 7 million car air conditioning systems by the end of next year.
