Proposed Refrigerant Alternatives at Boise State University
Bibliographic record
Abstract
Refrigerant usage has been under scrutiny in the last 25 years due to the Ozone Depletion Potential (ODP) of the most commonly used refrigerants. The Montreal Protocol called for the phase out of Chloroflourocarbons (CFC) and Hydrochloroflourocarbons (HCFC) refrigerants in response to the problem of ozone depletion. Because of the Ozone Depletion Potential (ODP) and high Global Warming Potential (GWP) of these refrigerants they have been and are in the process of being phased out. With this phase out comes the use of Hydroflourocarbons (HFC), which have no ODP but still have high GWP. Our proposed refrigerant alternatives to those currently in use at Boise State University are Ammonia, which is currently used in chillers to refrigerate food products, Propane, which is used in small scale refrigerants on an occasional basis, and R-1234yf which is a hydrofluoroolefin (HFO) that is currently in the research and development stage for use in automobile air conditioning units. These alternatives are proposed because of their low to nonexistent ODP and GWP, but are currently in the research and development stage for use in large scale chillers.

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.
