Résumé

Insulated boxes with Phase Change Material (PCM) are critical for last-mile food delivery, yet they struggle with temperature management with high temperature and high temperature heterogeneity. This study develops two heat transfer models for a 3-kg expanded Polystyrene boxes containing 200 g gel pack placed on top of 3 kg cod during transportation. The first is a lumped model assuming uniform cod temperature, and the second is an excitation-response model predicting temperature variations at different positions. Three temperature scenarios were examined: static conditions at 5 °C and 21 °C, and a dynamic condition fluctuating between these two temperatures. Experimental validation demonstrated strong correlation between predicted and measured temperatures with the difference less than 2 °C. The lumped model offers insights for optimizing box design, including insulation, PCM configuration and product loading, while the excitation-response model enables precise temperature prediction across the box. These models provide a comprehensive approach to improve thermal performance in food delivery packaging.
