Abstract

fetched live from OpenAlex

In the present study, recent research is considered about new generation refrigerant R-1234yf and R-1234ze (E). Chlorofluorocarbons (CFCs) had been phased out under the Montreal Protocol, CFC alternative refrigerants are searching for based on the condition of no chlorine atoms because of zero ODP. It seemed that conversion from CFC refrigerant to HFC refrigerant or natural refrigerant had progressed smoothly in the two decades. As for the low GWP refrigerants, hydrofluoric-olefins (HFOs), especially, HFO-1234yf (CF3CF=CH2: 2, 3, 3, 3-tetrafluoropropene) and HFO-1234ze (E) (CF3CH=CHF: trans-1, 3, 3, 3-tetrafluoropropene) are recently focusing in the world. Both of these HFOs have low GWP values (HFO- 1234yf is 4 and HFO-1234ze (E) is 6), and expecting as the next generation refrigerant. R-1234yf and R-1234ze (E) can used in mobile air conditioning and ejector refrigeration system.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
