Interpretation of the EU PFAS Restriction Proposal and Its Impact on R&AC Industry
Bibliographic record
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.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
