Abstract
Energy and water are essential for life. In the last decades, the energy demand has presented a high growth, stimulating the search for renewable sources of energy. At the same time, drinking water is also becoming a scarce resource. In this way, technologies that promote the preservation of these two resources are gaining worldwide prominence. Solar chimneys are devices that use solar energy to generate a flow of hot air, which can be used to movement wind turbines and produce energy. Recently, several studies have proposed the use of the heat generated for water desalination. The present work proposes a mathematical model for a solar chimney for the production of energy and drinking water for the city of Brumadinho, Brazil. The results will be compared with literature data for the city of Dalian, China. The proposed solar chimney has as main components a solar collector, a tower, a wind turbine and a high efficiency condenser. The model will be defined based on three models in the literature. It is intended to evaluate the influence of the collector size, solar irradiation and the efficiency of the generator on the electrical power produced and on the overall efficiency of the system.
