Abstract(s)
No setor agroindustrial alentejano têm sido detetadas diversas deficiências nos
processos produtivos, responsáveis por desperdícios e custos de energia desnecessários que
poderiam ser evitados através da adoção de medidas corretivas apropriadas. Os sistemas de
frio, que possuem um peso relevante no consumo global, constituem um importante foco
de localização dos gastos observados.
O presente trabalho surge como forma de analisar o padrão de utilização de energia
naquele setor, identificar as causas que originam os desperdícios encontrados e, também,
sugerir e avaliar o impacto de medidas como forma de os atenuar. O destaque é
especialmente atribuído aos sistemas de frio.
Para tal foi efetuada uma recolha de dados a respeito das caraterísticas e consumos
energéticos de uma amostra de empresas no Alentejo, uma organização e análise gráfica da
informação e um estudo técnico-económico de medidas de eficiência energética préselecionadas.
Construiu-se ainda um simulador do consumo energético em câmaras
frigoríficas para auxiliar aquele estudo, determinando-se a economia potencial de cada
medida.
In the agroindustrial sector from Alentejo it has been noticed several deficiencies located in the production processes, which are the cause of unnecessary energy losses and costs that could be corrected through the implementation of adequate measures. Refrigeration systems, which have a huge weight in global consumption, are also an important location where those losses may be found. Present work aims to analyze the behavior of energy use inside that sector, to identify causes of energy losses and also to suggest and to evaluate the impact of pre-defined measures as a way to diminish those wastages. Focus is primarily given to refrigeration systems. To accomplish such goals a data collection was conducted in a sample of companies located in Alentejo, in order to retrieve information about their characteristics and energy consumptions. Data was organized to perform a graphic analysis, and finally a technical and economical study was done to a set of pre-defined energy efficiency measures that are possible to apply. In order to help this study, it was built an energy consumption simulator of cold chambers to determine the potential savings of individual measures.
