Abstract
Refrigeration and air conditioning systems is a recurring theme in academia and industry. In this sense, twelve combinations of layout, fan velocity and diameter as well as initial temperature, were studied for a small refrigerator employed as a domestic wine cellar. The chamber utilizes a forced convection fan installed in the ceiling and a thermoelectric plate with a coupled fan, installed on the back wall. Simulations were done on a commercial code that works with finite element method. Results obtained led to the conclusion that, for this type and size of refrigeration chamber, the best positioning of the ventilating units and thermoelectric cell is the center of the inner walls, respectively upper and posterior. The simulations showed that the increase of fan velocity, even as the increase of its diameter, did not promote better refrigeration. Contrarily to the mainstream found in the literature, the positioning of the cold source higher also did not promote better results. The friction of the wind-jet with the walls seems to have promoted unwanted heating. New simulations with other layouts are recommended in order to increase the accuracy of the conclusions.
