Abstract
This paper deals with a thermo-mechanical exergy analysis of Balcova Geothermal District Heating System (BGDHS) in Izmir, Turkey using actual system data and an assessment of the district heating system performance, energy and exergy efficiencies, and exergy destructions. The exergy destructions in the overall BGDHS are quantified and illustrated using an exergy flow diagram. Also, both energy and exergy flow diagrams are compared. The exergy destructions in the system particularly occurs in terms of the exergy of the fluid lost in the pumps, the heat exchanger losses, the exergy of the thermal water (geothermal fluid) reinjected and the natural direct discharge of the system, accounting for 3.06%, 7.24%, 22.66% and 24.1%, respectively of the total exergy input to the BGDHS. Both energy and exergy efficiencies of the overall BGDHS are investigated for system performance analysis and improvement and are determined to be 37.60% and 42.94%, respectively.

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 it
