| 在《〈关于消耗臭氧层物质的蒙特利尔议定书〉基加利修正案》的履约和“双碳”战略的双重驱动下，制冷剂替代是制冷空调领域最为关注的热点之一。采用热物性相近的低GWP的HFOs制冷剂和天然制冷剂作为替代品，实现HFCs的削减被认为是较为合适的替代技术路线；但随着2023年2月欧盟出台的PFAS限制提案，引发了对HFOs制冷剂替代前景的担忧，这可能影响全球制冷剂替代发展。因此，首先对PFAS物质进行了介绍，分析了含氟制冷剂与PFASs的关系，并对PFAS法案的形成脉络和关键内容进行了解读，总结了不同领域对此的观点，希望对未来制冷剂替代方案的制定提供一定思辨意义和参考价值。 |

| Abstract: |
| Driven by the compliance of the Kigali Amendment to the Montreal Protocol on substances that deplete the Ozone Layer and the "carbon peak and carbon neutrality" strategy, refrigerant substitution has become one of the most important hot spots in the R&AC(refrigeration and air conditioning) field. Using low-GWP HFO refrigerants, which have similar thermal properties to natural refrigerants, as alternatives to achieve phase-down of HFCs, represents an appropriate replacement technology. However, with the announcement of the EU’s PFAS restriction proposal in February 2023, some concerns regarding the future of HFOs have emerged, which could affect global refrigerant substitution development. Therefore, this study introduces PFASs and analyzes their relationship with fluorinated refrigerants. We then interpret the formation and key contents of the proposed PFAS law. Finally, this paper summarizes the views of different fields on this issue to provide discernment and reference values for the formulation of future refrigerant substitution programs. |
