Analysis of influence of running time on heat transfer efficiency of buried tube heat exchanger under different working conditions
Bibliographic record
Abstract
There are still some problems with the actual heat transfer in ground-source heat pump systems. In order to study the influence of different working conditions on the heat exchange efficiency of the buried tube heat exchanger, the temperature field around the buried tube heat exchanger is simulated by using fluent software. The results show that the closer the temperature field is to the tube wall, the greater the temperature change is, and it has no effect on the soil layer with larger radial distance. In summer condition, soil temperature and heat transfer increase with increasing inlet velocity of working medium. When different backfillers are used, the backfillers with relatively large thermal conductivity can improve the heat transfer and improve the heat transfer efficiency. By analyzing the influence of different working conditions on the heat transfer efficiency of the buried pipe heat exchanger, the research results can provide reference value for the practical design of buried pipe and the future heat transfer simulation optimization of the heat pump system.

How this classification was reachedexpand
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.
