Potential of a Solar Organic Rankine Cycle with Evacuated-Tube Solar Collectors as Heat Source for Power Generation in Thailand
Bibliographic record
Abstract
This paper presents a potential of a solar organic Rankine cycle (ORC) with evacuated-tube solar collectors with F R ( τα ) of 0.81, F R U L of 2.551 W/m 2 K as heat source for generating electricity under the climate of Thailand. The power output of the ORC power plant was 280 kW and the ORC working fluid was R245fa. The weather conditions of Chiang Mai (18.783 o N, 98.983 o E ) , Ubon Ratchathani (15.233 o N, 104.783 o E), Hat Yai (6.91 o N, 100.43 o E ) and Bangkok ( 13.66 o N, 100.56 o E ) represented the northern, northeastern, southern and central part of Thailand, respectively were taken as the input data of the calculations. It could be found that at Chiang Mai, the levelized electricity cost was lowest which was 0.37 USD/kWh and the annual solar-to-electricity efficiency was 4.44%. At Bangkok and Ubon Ratchathani, the levelized electricity costs were slightly higher than that of Chiang Mai. At Hat Yai, the levelized electricity cost was found to be highest which was 0.43 USD/kWh. Key words : Solar organic rankine cycle; Solar collector; Electrical power generation; Performance analysis; Levelized electricity cost

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.
