A report by the International Energy Agency (IEA) is highlights both direct and indirect emissions caused by automotive air-conditioning, recommending governments take a holistic approach to addressing these issues that includes the adoption of low-GWP refrigerants, improved system efficiency and increased vehicle electrification. Few reports of this kind cover both direct and indirect emissions, usually Continue reading Auto-AC has big energy role to play in reducing emissions

The red R134a sticker on a refrigerant line fitting in the image above is found under the bonnet of a cutting-edge electric vehicle that is selling well in Australia. The Hyundai Kona. Inset is a J639 label from another hi-tech EV, the Jaguar I-Pace, sold in Australia carrying 850 grams of R134a. The Kona uses Continue reading Car-makers keep using high-GWP refrigerant

SNAP approval sought for broader use of YF The United States Association of Equipment Manufacturers (AEM) has proposed that R1234yf be considered for adoption in off-road mobile machinery under the US Significant New Alternatives Policy (SNAP). Representatives from AEM met with the US Environmental Protection Agency (EPA) in May to notify the regulatory body that Continue reading R1234yf for off-highway vehicles

Greater efficiency from a smaller refrigerant charge Successful trials of a secondary loop car air-conditioning system could open the door to a range of alternative refrigerants with smaller charge sizes. Potential benefits to the consumer include improved fuel efficiency and lower servicing costs. As a global average, energy consumption by car air-conditioning is estimated at Continue reading Secondary loop auto-AC trial results

Chemours Corpus Christi plant comes online The world’s biggest R1234yf factory is now operational at Ingleside in Texas, tripling YF production capacity for Chemours, which co-developed the HFO refrigerant with Honeywell. Resulting from a $US300 million ($A425m) upgrade of the Chemours Corpus Christi plant that began in 2016, this YF production boost will help the Continue reading R1234yf production capacity triples

The end of Australian car production by Ford, Holden and Toyota has not resulted in greater uptake of R1234yf refrigerant, according to the latest Cold Hard Facts report commissioned by the Department of the Environment and Energy. Cold Hard Facts (CHF) is a detailed examination of the Australian refrigeration and air-conditioning (RAC) industry, with the Continue reading Slow YF uptake increase since end of Aussie car-making

Barbara H Minor

Those who attended the 2015 VASA Wire & Gas convention will remember Barbara H Minor’s fascinating presentation about R1234yf, which she was pivotal in the development of. She has now been honoured with The Science of Chemical Industry (SCI) America Perkin Medal for her contribution to the research and development of refrigerants that address ozone Continue reading R1234yf inventor Barbara H Minor honoured with prestigious Science of Chemical Industry award

Mercedes-Benz S-Class with R744 AC system testing at a simulated 32km/h in a chamber set to 40°C and 40% relative humidity.

German brand sharing CO2 tech to accelerate automotive adoption After years of resistance, Mercedes-Benz parent company Daimler has finally decided to adopt R1234yf in some models, but only as a stepping-stone towards the range-wide rollout of cars with air conditioning systems using CO2 refrigerant (R744). The first R744-equipped models will be the high-end S-Class and Continue reading Mercedes-Benz adopts R1234yf as CO2 stepping stone

Mario Nappa

Lead chemist in the development of new industry-standard automotive refrigerant R1234yf Mario Nappa has been awarded the 2015 Winthrop-Sears Medal for entrepreneurial achievement. Dr Nappa, who worked with Wire & Gas 2015 keynote speaker Barbara Minor on the R1234yf project, already has quite a collection awards for technical achievement, invention and engineering excellence to go Continue reading R1234yf boffin wins Chemists’ Club medal
