Abstract

SISTEMA E MÉTODO DE DIAGNàSTICO ATRAVÉS DA CAPTAÇçO DE ONDAS MECÂNICAS EM SISTEMAS DE REFRIGERAÇçO E/OU ELETRODOMÉSTICOS. A presente invenção refere-se a um sistema e um método de diagnóstico para um sistema de refrigeração e/ou eletrodoméstico que, a partir de uma multiplicidade de grandezas físicas captadas determinam e informam a condição de operação do dito sistema de refrigeração e de seus componentes. Basicamente, as grandezas são divididas em dois grupos, sendo: (i) aquelas a partir das quais serão geradas assinaturas espectrais (grandezas relacionadas a vibrações mecânicas); e (ii) grandezas a partir das quais não serão geradas assinaturas espectrais. As grandezas do primeiro grupo são predominantes na análise do comportamento do sistema de refrigeração e/ou eletrodoméstico enquanto que as grandezas do segundo grupo se prestam a auxiliar, complementar e confirmar o diagnóstico obtido através das assinaturas espectrais. A captação das grandezas do primeiro grupo ocorrem por meio de sensores de ondas mecânicas (vibrações), acelerômetros ou ainda microfones, sendo estas grandezas dos tipos: ruído gerado pela movimentação ou presença de pessoas nas vizinhanças do sistema de refrigeração e/ou eletrodoméstico; e vibração dos componentes do sistema de refrigeração e/ou eletrodoméstico. O segundo grupo de grandezas, por sua vez, compreende parâmetros de temperatura e de tensão e corrente elétrica em componentes do sistema de refrigeração e/ou eletrodoméstico. As assinaturas espectrais geradas são comparadas com assinaturas padrões e, a partir disso, o diagnóstico do sistema é dado. Depois de diagnosticada, essa condição de operação é armazenada em uma base de dados e então um histórico de funcionamento do sistema é atualizado. As condições de operação são disponibilizadas para consulta, e, a partir da visualização do histórico, é possível constatar se o sistema de refrigeração e/ou eletrodoméstico e seus componentes apresentam falhas, ou não. Descreve-se também um compressor que pode ter o seu diagnóstico determinado pelo método e pelo sistema de diagnóstico da presente invenção.
