Abstract
Considerated are the main mean of refrigerants and coolants in air conditioning and refrigeration equipment. Also considered the standard set by international organizations for designation to refrigerants. Are considerate the classification of refrigerants impact on the ozone layer of the Earth, which was proposed by the Montreal Protocol in 1987. Classification implies three main groups of refrigerants: chlorofluorocarbons, hydrochloric fluorocarbons, hydrofluorocarbons. Are described and presented basic properties of refrigerants in table: composition, the potential depletion of the ozone layer and global warming, temperature glide and flammability. Are described the basic meaning of the temperature glide based on PI diagrams real azeotropic refrigerant R22 and zeotropic R407C. Are designated classification coolants for their intended purpose, state of aggregation, operating temperature range, freezing point? The final table are summarized the freezing point of aqueous solutions of refrigerants depending on their concentration.

Full frame distilled prediction
Teacher imitationNot 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.
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; both teacher heads agree on what is shown here.
