Abstract

SISTEMA E MÉTODO DE DIAGNàSTICO ATRAVÉS DA CAPTAÇçO DE ONDAS MECÂNICAS EM SISTEMAS DE REFRIGERAÇçO E/OU ELETRODOMÉSTICOS. SYSTEM AND METHOD DIAGNàSTICO THROUGH CAPTAÇçO OF MECHANICAL WAVES IN REFRIGERAÇçO SYSTEMS AND / OR APPLIANCES. 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. The present invention relates to a system and a diagnostic method for a refrigeration system and / or appliance that, starting from a plurality of physical quantities captured determine and inform the operational condition of said refrigeration system and its components . Basicamente, as grandezas são divididas em dois grupos, sendo: (i) aquelas a partir das quais serão geradas assinaturas espectrais (grandezas relacionadas a vibrações mecânicas); Basically, the quantities are divided into two groups: (i) those from which spectral signatures are generated (magnitudes related to mechanical vibrations); e (ii) grandezas a partir das quais não serão geradas assinaturas espectrais. and (ii) quantities from which spectral signatures are not generated. 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. The magnitudes of the first group are prevalent in the analysis of the cooling system behavior and / or appliance while the magnitudes of the second group lend themselves to assist, complement and confirm the diagnosis obtained through the spectral signatures. 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; The capture of the first group of magnitudes occur by mechanical wave sensor (vibration), accelerometers or microphones, which are magnitudes of the types: noise generated by the movement or presence of persons in the vicinity of the cooling system and / or appliance; e vibração dos componentes do sistema de refrigeração e/ou eletrodoméstico. and vibration of the components of the refrigeration system and / or appliance. 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. The second group of magnitudes, in turn, comprises parameters of temperature and voltage and electric current components of the refrigeration system and / or appliance. As assinaturas espectrais geradas são comparadas com assinaturas padrões e, a partir disso, o diagnóstico do sistema é dado. The generated spectral signatures are compared with standard signatures, and from that, the system diagnosis is given. Depois de diagnosticada, essa condição de operação é armazenada em uma base de dados e então um histórico de funcionamento do sistema é atualizado. Once diagnosed, this operating condition is stored in a database and then an operation history of the system is updated. 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. The operating conditions are available for inspection, and from the history view, you can see whether the cooling system and / or appliance and its components are faulty or not. Descreve-se também um compressor que pode ter o seu diagnóstico determinado pelo método e pelo sistema de diagnóstico da presente invenção. It also describes a compressor that can be determined by the diagnosis method and diagnostic system of the present invention.
