Análise comparativa entre a capacidade frigorífica e carga térmica de armazéns climatizados

Abstract

Several productive sectors depend on the support of industrial refrigeration in their storage processes to maintain and conserve products against agents that can cause changes in their quality until delivery to the customer. For this, sophisticated equipment are used, that operating in the appropiate form, they manage to conserve the quality of refrigeration and a reduce energy. This project purpose to evaluate the potential of improving the energy efficiency of climatized warehouses of a multinational company. For that purpose, six warehouses (A, B, C, D, E and F) containing thirty-five refrigeration machines were evaluated by means of the analysis of their thermal loads. All these data were tabulated and the values of conduction, product flow, metabolism of people, lighting, equipment and infiltration were analyzed. After the evaluations, the warehouses presented a cooling capacity higher than the demanded thermal load. With these data, we can conclude that it will be necessary to perform a rotational operation of the equipment in the other climatized warehouses according to the necessity. The proposal also fits in the installation of air curtains in the access doors of the same ones, in order to reduce the thermal load of infiltration and approach to the refrigerating capacity present in the warehouses. Therefore, the analysis made it possible to find in each climatized environment possibilities for improvements to optimize the product storage process.
