For an electric car to deliver the best capabilities and comfort, the temperature of its components and cabin must be managed effectively.  Batteries and control units that get too hot during operation, for example, can cause degraded performance, charging and range issues. Ineffective cabin heating and cooling solutions, similarly, can result in excessive power draw … Continue reading All-electric Audi Q4 e-tron features two cooling loops, R744-charged heat pump

It’s official: Mercedes-Benz has confirmed to SightGlass News that it is no longer pursuing carbon dioxide as an automotive refrigerant. The experience of CoolCar Hamilton with grey import R744 Mercedes models, as featured in Issue 23 of SightGlass News, suggests the systems are problematic. An inability to cool effectively in hot climates, as experienced by … Continue reading Mercedes-Benz dumps R744

By Craig Van Batenburg (Article reproduced by permission of SAE International) The Automotive Career Development Center (ACDC) that I founded over 20 years ago provides training and tech support to the world’s independent electric-vehicle (EV and hybrid) technicians, who will be asked to fix and maintain the systems as they age. Our facility in central … Continue reading Heat pump technology a game changer for widespread electric vehicle adoption

The Society of Automotive Engineers and Daikin are reportedly working to assess the performance and safety of a new refrigerant blend called D1V140 that is 77 per cent R1234yf, with the rest being a mystery Daikin-developed product called HFO1332(E). D1V140 is said to deliver better heat pump performance than YF, which has been found to reduce system capacity by … Continue reading Daikin developing YF blend for EV heat pumps

Honeywell has announced that industrial enclosure and air conditioning specialist Philip Doyle Manufacturing (PDM) will use its Solstice N15 refrigerant. Based in Ontario, Canada, PDM will employ the N15 refrigerant in industrial air-conditioning systems designed for applications such as overhead cranes. N15 is designed as a replacement for R134a, R227ea and R124 and an HFC/HFO … Continue reading Cranes cooled by N15

Latest Cold Hard Facts report shows slowly increasing OEM uptake of R1234yf in Australia THE latest Cold Hard Facts report into Australia’s air-conditioning and refrigeration industry reveals that R1234yf is finally gaining a foothold in the local automotive market. In other industry sectors, lower global warming potential (GWP) refrigerants including those based on or blended … Continue reading HFO still on the go-slow in Australia

Technology will help stem illegal sales, reduce influx of illicit refrigerants EFFORTS to counter the extensive illegal refrigerant trade in Europe are about to be bolstered by a new advanced software system from the United Kingdom.  The system, which will be developed by online trading specialist Vistalworks, will be designed to automatically find and identify … Continue reading Refrigerant robocop

There is no doubt that refrigerant-based thermal management of electrified drive systems and batteries will place those with strong knowledge and skills in mobile air-conditioning and auto-electrical systems at the forefront of the sector in years to come. The accelerating adoption of this thermal control method for critical systems in vehicles also highlights the importance … Continue reading Precise refrigerant charge essential to maximise EV range: Study
