Abstract

fetched live from OpenAlex

CFCs such as Freon 11,12, 22 and HCFCs such as Freon 22 are the refrigerant that depletion the Ozone, and so their production/consumption will be phased on under international legislation ( Montreal Protocol, Vienna Treaty, Kyoto Protocol, Keppres 1992, Kepmen.Deperindag 1998, SNI 06-6500/65011/65012- 2000) . Depletion of the ozone, that mean the increasing the amount of ultra violet light that reach us, this increases the incidence of skin cancer, eye cataract and reduces crop yields, etc\nThe new generation of the hydrocarbon refrigerant is MusiCool, because of The production by Pertamina near The Musi River in Palembang. To replaces the CFCs, HCFCs , there are several alternative refrigerants. It are HFCs (hydro Flouro Carbons) and Hydrocarbons (CA) refrigerant ( Petrozon, Musi Cool). Petrozon and MusiCool are produced by Pertamina, its blend of butane, isobutane, propane. But MusiCool is a new product (2004) of the Indonesian hydrocarbon refrigerant and are produced by Pertamina, Plaju South Sumatera.\nMusiCool is natural refrigerant, its environmental friendly and at least the performance as well as CFC/HCFC, and in many cases running costs from electricity consumption will reduces. The comparison of the Global Warming Potential (GWP) base 500 years: MusiCool : HFC134a : CFC-12 = 3 : 1300 : 4000. The Ozone Depletion Potential (ODP): MusiCool : HFC134a: CFC-12 = 0 : 0 : 1 . And The Atmospheric life time (year): MusiCool : HFC134a : CFC-12 = I : 15 : 120 . But the Hydrocarbon refrigerant ( Petrozon, MusiCool) are flammable when mixed with air and was ignited. If the MusiCool concentration in the air is not more than 2%, there is not enough for combustion (self ignition about 473° C).\nThere are a three products of the MusiCool, ie : MC 12, MC 22, and MC 134. The Characteristic of the MC 12 is similar with Freon 12, MC 22 similar with Freon 22 and MC 134 similar with HFC 134a.\n\nKeywords : Hydrocarbon refrigerant, Friendly Ozone, Refrigeration machine.

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.
