Abstract
This work presents the design, modeling, and evaluation of a portable cooling system based on Peltier modules, aimed at food preservation. The system was developed in collaboration with the company POLISUR 2000 S.L.U., which was interested in an efficient solution for portable coolers. Based on the container provided by the company, the cooling system to be installed was designed, and the dynamics of the complete system were modeled using a gray-box approach. The model was calibrated with experimental data and validated through cross-validation and standard metrics such as the root mean square error (RMSE) and the coefficient of determination (R²). Using the identified model, the system's ability to reach temperatures around 5 °C was simulated and assessed. Finally, a structural redesign was simulated, which enabled compliance with the operational requirement defined by the company, and the energy cost of operating the new system design over a 24-hour period was estimated.
