Testing and rating non-ducted air conditioners in Malaysia: The applicability of ISO standard 5151
Bibliographic record
Abstract
Air conditioners are one of the major energy-consuming appliances in the Malaysian domestic sector. According to a load survey, air conditioners account for around 8.3% of the total residential electricity consumption in Malaysia. To reduce the energy consumption in this sector, Malaysia Energy Center is considering implementing minimum energy efficiency standards for room air conditioners sometime in the coming year. The first step towards adopting energy efficiency standards is to create a test procedure for rating and testing this appliance. An energy test procedure is the technical foundation for all energy efficiency standards, energy labels, and other related programs. As room air conditioners are a climate-dependent appliance, the climatic condition for a particular country or region is an important determinant in developing the test conditions. Therefore, before setting the test conditions, the requirements for a specific country and region must be clarified. This article is an analysis of the applicability of ISO 5151 nonducted air conditioner test conditions, based on the climatic conditions in Malaysia. International adoption of ISO 5151 by several countries is also discussed. There is a trend towards international harmonization of appliance test standards; this work can be considered as support to that end.

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.
