Experimental and Theoretical Investigation on a Solar Chimney System for Ventilation of a Living Room
Bibliographic record
Abstract
The present work relates to the analysis of an energy system based on the solar chimney for passive ventilation of a living space. It consists of an experimental and theoretical study of the energy performance according to some geometrical and environmental parameters. The designed prototype was installed and followed for several days. In parallel, a numerical code was developed in FORTRAN platform to simulate the phenomena in the solar chimney and compare the theoretical results with those experimental in the transient regime. The results obtained relate to the distributions of temperature on the glazing, within the airflow and on the internal wall of the chimney. The hourly rate of air change (ACH), the air-outlet velocity and its mass flow rate have also been determined. The comparison of the results obtained in this study with those of the literature has shown a good agreement. The obtained results have shown that the incidental solar radiation plays a fundamental role in the energy performance of such systems and there is an optimum value of the ratio between the width of the chimney and the wall opening for a high rate of air renewal.

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.
