Abstract

"CIRCUITO ELETRôNICO PARA EQUIPAMENTOS DE REFRIGERAçãO RESIDENCIAIS E COMERCIAIS". O escopo desta patente compreende um circuito eletrônico desenvolvido para substituir os usuais sistemas de refrigeração dotados de compressores de gás, presentes nos equipamentos e aparelhos de refrigeração comercializados atualmente para uso residencial, podendo também ser utilizados conjuntamente com estes sistemas convencionais, contribuindo para elevar a sua vida útil, este novo circuito, que propicia sensível economia de energia, destacando-se pela sua simplicidade e reduzido custo de fabricação e manutenção. Basicamente, o novo circuito de refrigeração é composto de uma ou mais pastilhas termoelétricas (1) de efeito Peltier, cada uma delas tendo sua face "fria" (2) provida com um dissipador (3) e disposta no interior da câmara de refrigeração (4) de uma geladeira ou outro aparelho semelhante, enquanto a face externa (5) exibe um segundo dissipador (6), sendo dita pastilha eletricamente conectada a uma placa circuital (7) (PWM), que compreende um gerador de pulsos (8), um controlador de ciclos (9) e um módulo de potência (10), alimentada por meio de corrente contínua derivada de uma bateria ou da saída de um retificador de corrente alternada, sendo o acionamento e desligamento do circuito determinados por um termostato de duplo par de contatos, ou ainda por um par de sensores (11) e (12), dispostos no interior da câmara (4), enquanto uma segunda versão prevê a combinação do circuito acima com um sistema de refrigeração convencional, provido de compressor (13), resfriador (14), condensador (15), válvula de expansão (16) e evaporador (17), comandados por um termostato de três contatos ou por um termostado de três contatos ou por três sensores independentes (11), (12) e (18).
