Summary

This article is describes a study about the air flow distribution inside a refrigeration chamber, using computational fluid dynamic (CFD) simulation. The software used to perform this study was Fluent 14, from Ansys. The main objective was to study the air flow inside a cold chamber and the influence of air deflection and other strategies to achieve a better efficiency in air flow, under partial load product conditions. Special attention was given to the situation when a small quantity of product is located in a small part of the chamber. Measurements of temperature and air velocity were made inside the cold chamber, to validate the model. The results demonstrate that the air recirculation inside the refrigerated chamber, when loaded by a reduced quantity of product, is strongly influenced by the localization of product and localization of evaporator. To this situation the best air circulation of interior air is achieved by the introduction of an air deflector outside the evaporator.
