Análise técnico-econômica da implantação de um sistema de aquecimento solar para suprir a demanda de água quente dos vestiários de um frigorífico localizado na região Oeste do Paraná

Abstract

This work proposes a system of hybrid heating water using primary source solar energy and an auxiliary source, electricity or GLP for auto-completion of heating. This paper had as main objective to measure and analyze the economic viability of a solar heating system water to meet hot water demand in the poultry slaughterhouse in western Paraná. For this different scenarios were studied, varying both the type of solar collector (closed plane or vacuum 'U' shaped) and the auxiliary power source, and then compared to conventional water heating systems. The F-Chart method and a calculation routine developed in this dissertation were used to size the systems. For this project, the study showed the economic viability of all scenarios of solar water heaters in conjunction with an auxiliary power source. The most economically worthy configuration was the use of flat solar collectors and electric power as an auxiliary power source. The comparison with the use of a conventional source showed R $ 92,916.84 NPV, IRR 59.9% and turnaround time of about 1 year and 11 months.
