Abstract
Un conjunto perfeccionado de control variable para controlar el flujo de aire acondicionado a una zona, del tipo que incluye una caja que tiene una entrada para recibir aire acondicionado desde una fuente de suministro de aire acondicionado y una salida para entregar aire acondicionado a la zona, una cámara impelente de entrada para conectar la caja con conductos procedentes de la fuente de suministro, un registro situado dentro de la caja para controlar el flujo de aire a través de la misma , dividiendo el registro a la caja en una cámara de expansión y una cámara de salida, un dispositivo de medición del flujo de aire para medir el flujo de aire a través de la caja un motor situado al exterior de la caja para controlar la apertura y el cierre del registro, y un órgano de control situado al exterior de la caja y que responde a la temperatura de la zona y al flujo de aire acondicionado a través de la caja para controlar el funcionamiento del motor, caracterizado porque el dispositivo de medición del flujo de aire comprende un tubo que tiene un extremo de aguas arriba y un extremo de aguas abajo, formando el extremo de aguas arriba una sección de orificio, una expansión brusca del orificio para formar una cámara de expansión en el extremo de aguas abajo formando el extremo de aguas arriba una sección de orifico, una expansión brusca del orificio para formar una cámara de expansión en el extremo de aguas abajo del tubo, una sonda de presión estática situada en la cámara de expansión del tubo, en la expansión brusca del orificio, una sonda de presión total que tienen su abertura paralela al flujo de gas y mirando hacia aguas arriba, y unos conductos que conectan la sonda de presión estática y la sonda de presión total a dicho órgano de control.
