Estudo de viabilidade técnica e econômica de um sistema de poligeração energética aplicado em uma unidade hospitalar

Abstract

Focus on renewable energy, as well as energy generating systems efficiency, has grown with the increasing planet´s energy demand and the predicted limitation on energy resources over the years. A good viable alternative to more efficient and clean energy production, given the environmental concerns, is utilizing a polygeneration system integrating multiple forms of energy storage and production combined. The studies on polygeneration grow as the years go by and hospital units have proven to be promising system installation sites, due to its high energy demand through the year, using distinct kinds of energy, such as electric, heat, as well as steam in bigger installations. The present study aims to propose a polygeneration system model, integrating multiple forms of energy generation, including photovoltaic systems, heat pump and other existing storage models by analyzing a small hospital unit in Bahia´s countryside. The study develope a model of the individual components and their integration on the system. After proposing the model, was anallyzed technical and economic viability. For that, values for COP, energy saving, prediction on macro investments for the main components model and financial indicators such as payback time, LPV and IRT were generated. The results showed that the polygeneration system proposed can supply the predicted energy demand for the hospital and can be considered an economic investment with attractive values according to the financial indicators calculated. The present study can also provide information data to be applied on other configuration systems and more elaborated optimizing simulations, for better projects on polygeneration in the future.
