EFICIÊNCIA ENERGÉTICA INDUSTRIAL – VIABILIDADE TÉCNICA ECONÔMICA E SUBSTITUIÇÃO DE MÁQUINAS E EQUIPAMENTOS

Abstract

The paper proposes to systematically evaluate the engineering parameters related to Energy Efficiency in the industries. This concept is associated with sustainability and the fact that there is a need to change our behavior in view of economic and environmental social issues, since natural resources are limited and human needs tend to be unlimited, whether by population increase, better standards of comfort and increased energy demand in industries, we can soon reach a critical point soon as ecosystems are degraded in search of new energy sources to meet the needs of society. With this vision, economic and environmental partner, companies are seeking a better efficiency in their production process, replacing outdated machines that require a large energy consumption, for machines that give a better response. As a consequence of this management mode, companies are reducing the costs to be paid to contracted energy concessionaires. After a bibliographic research and case study, the parameterization was applied indicating the current levels of energy efficiency, and highlighting the possible improvements in the place in relation to the reduction in consumption and financial savings. The place chosen for deployment is Cooper Standard Automotive, located in Varginha, Minas Gerais. After carrying out the current assessment of the level of energy efficiency, we looked for alternatives that would maximize this process. Thus, the proposed system reduces the total energy and water consumption, through equipment replacement. The old Chiller equipment has a 15.79% share of all the energy consumed by the company during the month. With the proposed improvements, exchange of old Chillers with more modern ones, this percentage of participation is reduced to 8.28%, considered a significant difference and an excellent level in efficiency.
