Abstract

fetched live from OpenAlex

<p>This thesis investigates the performance of Helical Steel Piles (HSPs) as in-ground heat exchangers for Ground-Source Heat Pump (GSHP) systems. Eight HSPs with integrated plastic tubing for fluid circulation were installed at the Eby Rush Transformer Station in Waterloo, Ontario. The CFD model simulations needed for the design of the experimental site as well as the installation process is detailed in Chapter 2. The control strategy and the tests required to assess the performance of the system are presented in the same chapter. Chapter 3 presents the CFD model modifications, optimization, and validation based on the harvested data from the experimental site. The capacity, coefficient of performance (COP), and power consumption of this novel system were investigated through conducting heating and cooling tests. The results indicate the feasibility of using HSPs as in-ground heat exchangers to provide sustainable thermal energy.</p>

Full frame distilled prediction

Teacher imitation

Not 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.
