Résumé

A comprehensive, validated numerical study is conducted to enhance temperature uniformity within a top- freezer refrigerator. The 3D model employs conservation laws, heat balance equations, and a porous media technique to accurately simulate airflow and thermal distribution inside a refrigerator with adiabatic walls. Three key parameters are investigated numerically: fan type, fan tilt angle, and shelf gap. Three commercial fans (Fan-1, Fan-2, and Fan-3) were considered. Fan tilt angles of 0◦, -10◦, and +10◦were examined as Case 1, Case 2, and Case 3, respectively. Four shelf gap configurations 0, 5, 10, and 15 mm were analyzed as Cases A through D. Results show that, excluding R1, temperature in the refrigerator compartment gradually increased from the Fresh Case to R2, R3, and the Vegetable Case, while remaining relatively constant in the freezer compartment. Based on performance, Fan-2 provided the best temperature uniformity. Additionally, a +10◦ fan tilt significantly improved thermal consistency compared to 0◦ and -10◦orientations. Furthermore, the maximum temperature uniformity was achieved with the widest shelf gap (15 mm, Case D).
