Abstract

Patente de Invenção: <B>''SISTEMA VENTILADOR''<D>. Um ventilador mecânico portátil (10) utiliza um compressor de velocidade constante (20) e um circuito de contorno de recirculação. Fluxo de contorno é governado por uma válvula de contorno deslocada por mola (26), assim conectada a ambos, à entrada (24) e à saída (28) da válvula de controle do fluxo principal (12), para manter uma pressão diferencial através da válvula de fluxo, suficiente para operar o ventilador com consumo mínimo de energia. A válvula de fluxo é operada por meio de um microprocessador (82), de acordo com tabelas de consulta derivadas de forma empírica para ambos, para produzir o fluxo de ar desejado e para fornecer uma medida daquele fluxo de ar.
