Abstract

SE PROPORCIONA UN SISTEMA DE VENTILACION PARA UN RECINTO EN UNA PLANTA DE ENERGIA NUCLEAR. EL RECINTO ALOJA UNA BOMBA DEL AGUA DE ALIMENTACION DE EMERGENCIA Y SU TURBINA DE VAPOR IMPULSORA. UN EYECTOR MONTADO EN EL RECINTO ES SUMINISTRADO CON VAPOR EVACUADO DE LA TURBINA DE VAPOR IMPULSORA. EL CHORRO DE VAPOR FORMADO POR EL EYECTOR ARRASTRA AIRE CALIENTE FUERA DEL RECINTO, CON LO CUAL PREVIENE LA EXCESIVA ACUMULACION DEL CALOR EN EL RECINTO. UNA ENTRADA DE AIRE EFECTUADA EN OTRA PARED DEL RECINTO SUMINISTRA AL RECINTO CON AIRE DE AMBIENTE FRIO. EL EYECTOR Y LA ENTRADA DE AIRE ESTAN SITUADOS PARA ASEGURAR QUE EL AIRE QUE ENTRA FLUYA SOBRE LA BOMBA, CON LO CUAL LA ENFRIA. UN CONDUCTO TRANSPORTA LA MEZCLA VAPOR/AIRE DESCARGADA POR EL EYECTOR A LA ATMOSFERA.
