Abstract

Patente de Invenção: <B>"UNIDADE DE CONTROLE DE TERMOSTATO ELETRÈNICO E O SEU USO EM CONTROLADOR DE TEMPERATURA DE MúLTIPLOS PONTOS PARA SISTEMAS DE REFRIGERAçãO E AQUECIMENTO"<D>. A presente invenção refere-se a uma unidade de controle de termostato eletrónico digital que compreende: - um elemento sensor de temperatura de junção p-n, - uma fonte de corrente constante para acionar o citado elemento de junção p-n, - a saída do citado elemento de junção p-n está ligada a um conversor analógico digital para produzir uma saída digital que está ligada a um circuito para corrigir a sensibilidade e os valores de desvio do sensor usando-se dados de calibragem armazenados em memória não-volátil, - a saída corrigida está ligada a uma entrada de pelo menos um comparador digital, e a outra entradaf de cada comparador digital recebe um valor de resistência digital a partir da citada memória não-volátil ou do meio de controle variável, - a saída do(s) citado(s) comparador(es) é filtrada usando-se filtros de ruído digitais, e é armazenada num engate de controle para estabelecer/restaurar a entrada de um engate de controle em função da saída do(s) comparador(es) digital ou digitais.
