Abstract
''CIRCUITO ELETRÈNICO PARA APARELHOS DE REFRIGERAçãO E DE CONDICIONAMENTO DE AR''. O escopo desta patente é um novo circuito eletrónico para substituição dos sistemas providos de compressores, empregados nos atuais aparelhos de refrigeração e ar condicionado, destacando-se pelo seu baixo custo, simplicidade de montagem e manutenção e elevado rendimento, além do reduzido número de componentes utilizados. Basicamente, este novo circuito de refrigeração compreende uma pastilha termoelétrica ( 1 ) de efeito Peltier e um circuito de modulação por largura de pulso ( 2 ) ''PWM" ('' pulse width modulation ''), alimentada por meio de corrente contínua, estando a referida pastilha ( 1 ) com sua face ''fria'' ( 3 ) disposta no interior de uma câmara de refrigeração ( 4 ) ou na face interna de um tubo de passagem de um fluido, enquanto a face externa ( 5 ) exibe um dissipador ( 6 ), sendo dita pastilha eletricamente conectada à placa circuital ( 2 ), a qual compreende um gerador de pulsos ( 7 ), um controlador de ciclos ( 8 ) e um módulo de potência ( 9 ), de maneira a manter a freq³ência e a tensão da corrente que atravessa a pastilha ( 1 ) dentro dos valores ideais, variando apenas o ciclo de atividade conforme a carga térmica exigida, podendo um mesmo circuito ( 2 ) comandar simultaneamente diversas células termoelétricas ( 1 ), dispostas em série e/ou em paralelo.
