| 抄録(英) | Driven by electric mobility and mobile machinery needs, the market demands efficient thermal management with refrigerants that work across climates, meet low-GWP and PFAS-free requirements, and require minimal system changes. This study evaluates two novel blends, R474B and R491A, as drop-in candidates versus common automotive refrigerants. Laboratory tests under heating, cooling, and high-load conditions show performance can be limited by existing equipment and safety constraints, though cooling and dehumidification needs were met. Overall, the results show the new refrigerants are technically viable and offer a promising path for future EV thermal management. 翻訳 |
