Development of a geothermal plant combined with absorption and Rankine cycles for trigeneration
Bibliographic record
Abstract
A thermodynamic modeling through energy and exergy approaches is performed on a newly developed system for hot water, cooling and electricity production. The geothermal power plant supplies thermal energy to the Rankine cycle to produce hot water and green electricity. The absorption refrigeration system is integrated with the geothermal plant for hot water and cooling. Various parametric studies are conducted to present the exergetic and energetic losses of each subcomponent. The results of the parametric studies indicate that the maximum useful output power of the turbine is obtained as 5991 kW at a geothermal injection temperature of 460 K. Moreover, the highest heat cooling rate of the evaporator is 4397 kW obtained at the inlet mass flowrate to the pump of 30 kg/s. The highest energetic and exergetic coefficient of performance values at inlet temperature to pump of 30°C are 0.584 and 0.287, respectively. Furthermore, the maximum energy and exergy coefficient of performance values at −5°C of the outlet temperature of the evaporator are found to be 0.58 and 0.231, respectively.

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.
