Résumé

This paper is focussed on the study of the temperature and air distribution inside household frost-free refrigerators. It is well known that the correct air and temperature distribution inside the refrigerated chamber is the most important factor that affects refrigerator efficiency. In frost-free refrigerators the cooled air is supplied directly inside the fresh food and vegetable cabinets. Therefore, studies intended to establish the actual air flow and temperature distributions inside these cabinets are relevant in order to improve temperature homogeneity and to reduce energy consumption. The proposed methodology is based on the numerical simulation of the cabinets by means of computational fluid dynamics. Turbulence is solved by means of LES models. Unsteady three-dimensional numerical studies are carried out, simulating the cooling process starting from a uniform warm temperature inside the refrigerator. Furthermore, the influence of inlet and outlet ports location is also investigated.
