Abstract

UN DISPOSITIVO ACONDICIONADOR DE AIRE ESTA DISPUESTO DE MANERA QUE UNA TENSION DE SALIDA DE UNA FUENTE DE ENERGIA COMERCIAL SEA CONVERTIDA EN CORRIENTE CONSTANTE POR UN CIRCUITO RECTIFICADOR Y UN CONDENSADOR, Y POSTERIORMENTE, SEA CONVERTIDA ADICIONALMENTE EN UNA TENSION DE CORRIENTE ALTERNA QUE TENGA UNA FRECUENCIA VARIABLE MEDIANTE UN INVERSOR BAJO EL CONTROL DE UN MICROORDENADOR, SUMINISTRANDOLA DESDE ALLI A UN COMPRESOR DE ENERGIA. ENTRE EL CIRCUITO RECTIFICADOR Y EL CONDENSADOR, SE SUMINISTRA UN FILTRO ACTIVO PARA CONFORMAR UNA CORRIENTE DE ENTRADA PARA QUE SEA UNA ONDA DE SENO APROXIMADO EN FASE CON UNA TENSION DE ENTRADA CONMUTANDO UN TRANSISTOR DE POTENCIA. LA SECCION DE CONTROL DE CONMUTACION Y EL MICROORDENADOR PARA CONTROLAR LA CONMUTACION SE ACTIVAN INDEPENDIENTEMENTE MEDIANTE FUENTES DE ENERGIA DISPUESTAS SEPARADAMENTE. LA SECCION DE CONTROL DE CONMUTACION SUMINISTRA UNA SEÑAL DE ALTO NIVEL CUANDO EL FILTRO ACTIVO ESTA EN UNA CONDICION NORMAL, MIENTRAS QUE SUMINISTRA UNA SEÑALDE BAJO NIVEL CUANDO EL FILTRO ACTIVO ESTA EN UNA CONDICION ANORMAL. SE SUMINISTRA UN CIRCUITO DE GENERA UNA SEÑAL DE BAJO NIVEL CUANDO EL SUMINISTRO DE ENERGIA HACIA LA SECCION DE CONTROL DE CONMUTACION SE APAGA. ESTO HACE POSIBLE QUE EL MICROORDENADOR DETERMINE LA OCURRENCIA DE UNA ANORMALIDAD EN EL FILTRO ACTIVO O EN LA SECCION DE CONTROL DE CONMUTACION INCLUSO CUANDO EL SUMINISTRO DE ENERGIA ESTA CORTADO.
