Abstract
The current global scenario presents a significant increase in energy demand for HVAC-R (Heating, Ventilation, Air Conditioning and Refrigeration) systems. Considering also that Brazil has the sixth most expensive energy in the world and that there is currently a greater scarcity of natural resources for energy generation, it is necessary to seek viable alternatives with lower energy consumption to the currently most used models, without that there is any loss of quality. In contrast to this, the refrigeration systems by absorption and incineration of garbage can be lines of studies and research to be considered, considering that it is possible to reduce the consumption of electric energy and equally the environmental impacts that the usual refrigeration systems by compression provide. In this context, one of the segments of Thermal Systems Engineering studied is the exergoeconomic analysis that comprises concepts of Heat Transfer, Fluid Mechanics and Thermodynamics, based on the Second Law of Thermodynamics and which uses the notions of optimization and economic analysis. Therefore, this work aims to carry out an exergoeconomic analysis of a hybrid system of waste incineration and absorption refrigeration for the range from 5 to 10 TR, with the specific objective of developing an exergoeconomic model for the hybrid system. absorption incinerator-refrigerator, to carry out the adjustment and experimental validation of the mathematical model, perform the parametric analysis and identify opportunities for optimization. This is an exploratory bibliographic research and an experimental research using an absorption refrigerator of the Center for Research and Development of Self-Sustainable Energy (NPDEAS) of the Federal University of Paraná, in which a model will be made with a macroscopic approach of the phenomena of mass transfer and heat of an absorption refrigeration cycle, applying the principles of conservation of mass and energy in steady state for each component of the cycle, that is, each component will be considered as a single control volume. It is expected that it will be possible to predict the behavior of the absorption refrigeration system and that it will be possible to develop a scientific analysis tool to design, control and optimize absorption refrigeration systems.
