Résumé

An experimental and numerical study was carried out using a model refrigerator in which heat is transferred by natural convection. This transfer takes place between a cold vertical wall and the other walls, which are exposed to heat losses. Simulations using CFD software was undertaken supposing a constant cold wall (evaporator) temperature, and laminar 3D-flow and taking into account heat transfer by radiation. Two cold wall temperatures were studied: -10 and 0°C. Two configurations were investigated: empty model refrigerator and model refrigerator filled with 4 blocks of hollow spheres. The comparison of the air temperature profile in these 2 cases makes it possible to study the influence of the product item.
