Study of Dehumidification and Regeneration in a Starch Coated Energy Wheel
Bibliographic record
Abstract
Energy wheels were designed using desiccant-coated materials to exchange energy between supply and exhaust air streams to reduce the energy required to condition ventilation air. Recent advances in energy wheel design that use biopolymer desiccant materials have provided the motivation in this paper to investigate the performance of starch coated energy exchangers. A small-scale high amylose starch (HAS) coated exchanger was built, and its transient response to a step change in inlet humidity was acquired and studied at conditions of variable air flow rate and temperature. The humidity response, dehumidification, regeneration capacity, and the rate of moisture removal were measured. The results demonstrate that greater regeneration flow rate and temperature can enhance the regeneration capacity. In spite of the increase in the regeneration capacity, the moisture recovery (latent) effectiveness decreased as the air flow rate and/or temperature increased. The effectiveness is reduced by 15% when the flow rate increases from 10 to 50 L/min at ω = 2 rpm; whereas, the difference in effectiveness is less than 4% at ω = 20 rpm. When the air flow temperature increased by 15 °C, insignificant changes in effectiveness were found below 4%. The results of this research are anticipated to contribute to future research and development on biopolymer coated energy exchangers.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
