Summary

This paper investigates a method combining one-dimensional (1D) and three-dimensional (3D) simulations for application in refrigerators to support refrigerator design optimization through integrated thermal and airflow analysis. Using AMESim simulation software, the method conducts 1D simulations and applies the generated data to the boundary conditions of 3D simulation in STARCCM+ for data interaction. The horizontal evaporator structure was optimized based on the prototype with a vertical evaporator as the case study. This modification further enhances the uniformity of airflow distribution and improves energy efficiency. The case study has significant design improvements, such as enhanced air distribution with airflow velocities of 2.4–3.0 m/s and increased effective storage volume. The calibrated heat resistance correction coefficients of the prototype were validated for broader applicability, establishing the framework as a practical reference for similar refrigeration systems. The developed methodology provides a robust platform for data-driven advancements in refrigeration design.
