Resumo

Há uma necessidade crítica de usar a energia solar abundantemente disponível em todo o mundo devido à crise energética global. O objetivo deste estudo é demonstrar o uso residencial de um motor Stirling alimentado pela energia solar em Karachi, Paquistão. O projeto foi realizado para produzir uma potência de 5 kW, a fim de abordar os problemas com a geração de energia da área doméstica e da área rural. O design foi simulado usando o MATLAB. O uso da energia solar como a entrada de calor do motor foi um dos principais componentes do design. Isso permitiu que o motor fosse construído para locais com muita radiação solar. Em regiões com abundante energia solar, fogões solares, aquecedores de ar solar e outros aparelhos podem ser usados. Para a geração de energia, no entanto, o motor Stirling foi escolhido. Os cálculos da intensidade do sol mostraram que 5 kW de saída do motor Stirling podem ser gerados a partir de 12 kW de eletricidade solar. O concentrador para se concentrar e refletir as radiações de entrada no motor Stirling foi selecionado como um prato parabólico solar. Esse processo aqueceu o fluido de funcionamento do motor, que então se expandiu e contraiu devido a forças termodinâmicas para produzir os golpes de energia do motor.
