Abstract

fetched live from OpenAlex

'Drop-in' working fluids for the domestic refrigerator are focus of research in developing countries like India where the useful life of a refrigerator is about twenty years, which is past CFC phase out commitment as per the Montreal Protocol. After analysing the different working fluids based on their thermodynamic properties, HC-290/HC-600a and FC-218/HFC-134a/HC-600a were focused for the study to assess their suitability as drop-in working fluids in domestic refrigerators. The most important component, compressor is tested for its chemical and material compatibility as per the Life Cycle Test. Result revealed that both the compressors with said combinations of refrigerant and lubricating oil have passed the test. FC-218/HFC-134a/HC-600a/MO combination showed slightly better results then HC-290/HC-600a/MO combination but HC-290/HC-600a is environmental friendly as compared to FC-218/HFC-134a/HC-600a having slightly high GWP. However, there is no commitment to phase out HFCs in near future by the government of India and FC-218/HFC-134a/HC-600a/MO can be safely used as a drop-in substitute.

Not 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.
