Barriers to the use of Low GWP Refrigerants in the Refrigeration and Air Conditioning Sector in Mauritius
Bibliographic record
Abstract
This paper is concerned with the issue of phasing out of Hydrofluorocarbons (HFCs) in Mauritius following the Kigali amendments of the Montreal protocol. For this purpose, a gap analysis was carried out among the major stakeholders in the Refrigeration and Air Conditioning (RAC) sector in Mauritius concerning the introduction of environment friendly refrigerants. Based on the gap analysis, it was found that the most frequently used refrigerants in the sector were HFCs and, to a lesser extent, hydrochlorofluorocarbons (HCFC). However, because of their negative influence on the environment, natural refrigerants such as ammonia (NH3), carbon dioxide (CO2) and Hydrocarbons (HC), having minimal impact on the environment, are being considered. On the other hand, HFOs, a new family of synthetic refrigerants also having low GWP have just appeared on the market. While these refrigerants have several advantages in terms of energy savings and thermodynamic efficiency, they also presents some drawbacks related namely to safety and availability on the market. In this paper, we discussed the major gaps in the implementation of these aforementioned new alternatives (i.e. NH3, CO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> , HC and HFOs). Additionally, we proposed some solutions to cater for these gaps. Finally, some conclusions are drawn on future possible policy and decision making with regards to the implementation of the above technology.

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.
