Modern requirements for refrigeration agents in transport air conditioners
Bibliographic record
Abstract
The Scientific advances, changes in national legislation in the field of combating the effects of global warming and market requirements have stimulated the development of fourth generation refrigerants. In contrast to the first and second generation refrigerants, which provided, along with the principle possibility of achieving a refrigerating effect, such qualities as durability and operational safety, the third and fourth generations include environmental constraints in a significant way. The identification of a link between leaks of traditional second-generation chlorofluorocarbon (CFC)-based refrigerants and the destruction of the protective atmospheric layer of ozone gave rise to the third generation of refrigerants. The Vienna Convention and the Montreal Protocol were the reaction of the world community, leading to the banning of ozone-depleting substances (ODS). At the same time, hydrochlorofluorocarbons were considered as temporary or transient and hydrofluorocarbons (HFCs) as long-term working bodies. Interest in the natural refrigerants ammonia, carbon dioxide, hydrocarbons and water has increased dramatically.

How this classification was reachedexpand
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; a candidate call from one teacher head, not a consensus.
