Abstract

Ventilador centrífugo de un acondicionador de aire. El ventilador centrífugo incluye un conducto de guía y un rodete. El conducto de guía presenta una placa frontal, una placa posterior y una pared en espiral para guiar un flujo de aire. La placa frontal está conformada con un abertura de aspiración y en una parte superior, comprendida entre la placa frontal y la placa posterior está prevista una abertura de descarga. El rodete se instala en el interior del conducto de guía para impulsar el aire aspirado a través de la abertura de aspiración hacia la abertura de descarga. El conducto de guía presenta asimismo un elemento antirruido para evitar que los ruidos producidos en un espacio intermedio comprendido entre la placa posterior y el rodete se emitan hacia la abertura de descarga.Centrifugal fan of an air conditioner. The centrifugal fan includes a guide duct and an impeller. The guide duct has a front plate, a back plate and a spiral wall to guide an air flow. The front plate is formed with a suction opening and a discharge opening is provided on the upper part, between the front plate and the rear plate. The impeller is installed inside the guide duct to propel the sucked air through the suction opening into the discharge opening. The guide conduit also has an anti-noise element to prevent the noise produced in an intermediate space between the back plate and the impeller from being emitted towards the discharge opening.
