Avaliação e projeto de um sistema de aquecimento solar para a moradia estudantil UFGD

Abstract

The increase in energy demand due to population growth and its demand for electrical and electronic equipment, in addition to the reduction of the supply of fossil fuels and the growing concern with the environment, has led to the search for renewable, less polluting and viable sources of energy from the point technical and economic view. Solar thermal power is an excellent alternative to these problems, since it is a non-polluting source and has its inexhaustible array. In this work, the insertion of a solar thermal system in the student residence of the Federal University of Grande Dourados (UFGD) was studied from the energy and economical analysis for the supply of hot water to the bath. The work was done using the ABNT NBR 15569 standard and the data were based on the consumption habits of the residents: time and time of use. Considering the impact on the energy cost of the electric shower at peak hours and the investment in the thermal solar water heating system, the financial attractiveness of this project was verified, with a return on investment of 4.96 years and an expectation of financial return of 213 % of the total invested at the end of its useful life.
