Recorded at the 45th annual Mobile Air Climate Systems Conference (MACS 2025) in Orlando, Florida, Honeywell experts explore the advantages of retrofitting older 134A systems with 1234YF refrigerant, highlighting its significantly lower global warming potential. They also discuss the growing complexity of thermal management in EVs, where efficient cooling for batteries and electronics is essential, and the ongoing search for standardized, high-performance refrigerants. Gain insights into the environmental benefits of transitioning to 1234YF, the challenges of EV thermal management, and the critical need for education and training in the automotive aftermarket.
