Abstract
Centrifugal chillers using CFC’s were made in India in the capacity range from 150 TR to approximately 700 TR. Currently, there are around 500 units operating in India ranging in age from 10 to 30 years. All of these units will have to be replaced eventually since CFC’s are to be phased out by 2010 in Article 5 countries as per Montreal Protocol. The World Bank has made a detailed study of the issue and proposed a Global Chiller Replacement Project whereby the old units will be replaced by the current generation of energy-efficient chillers using non-CFC refrigerants. This paper deals with a novel, alternate proposal in which solar thermal power is used to power an electric-driven compression chiller and a heat-driven absorption chiller; as a pair of units, which would replace 2 Centrifugal chillers. The concept is found to be economically viable as a CDM project. The simple payback period works out to be 2 1/2 years. The investments required are large which can be brought down if the cost of solar concentrator is reduced.

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.
