Abstract(s)
O elevado consumo energético e respetivo custo associado nas indústrias, tem sido uma questão que os gestores têm vindo a refletir cada vez mais. A forma como é consumida a energia é a base de análise para verificar se a sua utilização está a ser feita de forma eficiente.
As razões para as empresas apresentarem consumos desnecessários são diversas e requerem um estudo completo às instalações. Neste seguimento, surge a implementação de medidas de racionalização de energia com o objetivo de reduzir a fatura energética das industrias e/ou de ajudar no cumprimento de compromissos nacionais e internacionais.
Esta dissertação foi elaborada no decorrer de um estágio curricular realizado na empresa Ecoinside, no âmbito de uma nova auditoria feita pela empresa, com base no SGCIE, a uma indústria consumidora intensiva de energia na área da metalomecânica.
Neste contexto, o principal objetivo deste documento é o estudo de medidas de racionalização de energia bem como a respetiva análise de viabilidade económica, com base em indicadores. Também é apresentada uma análise temporal dos consumos energéticos da indústria e o retrato da auditoria feita em 2010, bem como da nova auditoria realizada no decorrer do estágio, sendo esta a base para o estudo das medidas.
Deste modo, foram feitas medições aos consumos da indústria, realizados levantamentos termográficos a equipamentos e recolhida informação relativamente à iluminação existente bem como, de todos os dados e informações para a formulação de medidas de racionalização de energia.
Nowadays, energetic consumption and the associated high costs claims more attention by factory managers. The way energy is consumed is the basis of analysis to see if it´s use is being efficiently. There are many reasons why factories present unnecessary consumption and, because of that, it is important to do a complete study of the facilities. In this way, the implementation of energy rationalization with the objective of reducing the energy invoice of industries and/or help to satisfy the national and international commitments, is required. This master’s thesis was elaborated in the course of a curricular internship at the company Ecoinside with the objective to realize a new audit, based on the SGCIE, to an intensive energy consumer industry. The main goal of this master’s thesis is the study of energy rationalization measures as well as their economic feasibility analysis, based on indicators. It is also presented a temporal analysis of the energy consumption and the results of the audit done in 2010. The new audit carried out during this internship is the basis for the study of the measures. To provide this relevant information, measurements were made to the consumptions of the industry, thermographic surveys to equipment and was also collected information regarding the existing light as well all data and information for the formulation of rationalization of energy measures.
