Resumo

A refrigeração tornou-se parte integrante do nosso dia a dia e pode ser considerada um processo quase impossível de substituir. Portanto, a única forma de tornar esse processo eficiente é reduzir o consumo de energia dos componentes do refrigerador. Uma maneira de fazer isso é reduzir o consumo de energia do compressor adicionando nanopartículas a um refrigerante ou lubrificante. Este estudo tem como foco a produção de nanolubrificante (Al2O3/lubrificante sintético) e a dispersão do nanolubrificante no compressor R-134a. Este estudo investiga quanta energia pode ser reduzida quando nanopartículas de óxido de alumínio (Al2O3) são dispersas em lubrificante SL-32 (líquido base). Foi feita uma comparação entre o lubrificante SL-32 com e sem adição de nanopartículas de óxido de alumínio e mostrou uma redução de 0,913% no consumo de corrente e 2,74% na potência na mesma temperatura inicial de 31° C em ambos os casos. Portanto, pode-se concluir que nanopartículas de alumina podem ser utilizadas para reduzir a energia utilizada pelos compressores, criando um nanolubrificante com lubrificante SL-32.
