Résumé

During last years, supermarkets have increased the demand for closed refrigerated display cabinets due to new regulations and trends on energy and sustainability. However, the performance of this type of refrigerated display cabinets is not completely known, being of utmost importance how the airflow distributions could affect over the temperature distributions inside the cabinet. Consequently, this work presents a numerical evaluation of the performance of closed display cabinets focusing on the effect of the sliding doors opening process. The set of computational fluid dynamics (CFD) simulations served to validate the use of immersed solid approach in order to accurately analyze and evaluate transient behavior of the turbulent air flow distributions and temperature evolutions inside the cabinet and overthe products, and characterizing the air curtain disruptions and the warm air entrainment during the opening process of the cabinet sliding doors (i.e. from closed doors, through doors opening process and to doors totally open).
