Abstract

UN SISTEMA DE REFRIGERACION DE CONTENEDOR (4) UTILIZA UN FLUJO DE AIRE INDUCIDO NATURALMENTE Y UN FLUJO DE AGUA DE GRAVEDAD SOBRE LA VASIJA DEL CONTENEDOR (6) QUE ENCIERRA UN NUCLEO REACTOR (8) PARA ENFRIAR EL CALOR DE DESINTEGRACION DEL NUCLEO EN DOS ETAPAS. CUANDO EL CALOR DE DESINTEGRACION DEL NUCLEO ES MAYOR, EL AGUA Y FLUJO DE AIRE SE COMBINAN PARA PROPORCIONAR REFRIGERACION DE EVAPORACION ADECUADA, SEGUN SE TRASPASA EL CALOR DESDE DENTRO DEL CONTENEDOR HASTA EL AGUA QUE FLUYE SOBRE EL MISMO. EL AGUA SE CALIENTA POR TRANSFERENCIA DE CALOR Y LUEGO SE EVAPORA Y SE REMUEVE POR EL FLUJO DE AIRE. DESPUES DE UN PERIODO INICIAL DE UNOS TRES O CUATRO DIAS, CUANDO EL CALOR DE DESINTEGRACION DEL NUCLEO ES MAYOR, EL FLUJO DE AIRE SOLAMENTE ES SUFICIENTE PARA REFRIGERAR EL CONTENEDOR.
