Abstract

UN INTERCAMBIADOR DE CALOR Y HUMEDAD TIENE UN ELEMENTO 4 FORMADO POR UNA TIRA DE MATERIAL DE FILTRO BACTERIANO QUE ESTA DOBLADA LATERALMENTE EN PLIEGUES Y CURVADA EN FORMA DE LAZO DE MODO QUE LOS PLIEGUES 41 Y 42 SE EXTIENDEN RADIALMENTE. EL ELEMENTO 4 ESTA SELLADO EN DERREDOR DE SU EJE EXTERIOR EN FORMA DE UNA ENVOLTURA CIRCULAR 1 QUE TIENE UNA LUMBRERAS AFILADAS AXIALES 2 Y 3 EN SU EXTREMO OPUESTO. UN DESVIADOR CONICO DE GAS, 46,47, ESTA SELLADO EN UNA ABERTURA CENTRAL DEL ELEMENTO 4 EN CADA LADO. EL GAS EXHALADO TEMPLA Y HUMEDECE EL ELEMENTO 4, EL GAS INHALADO SE FILTRA Y RECOGE PARTE DEL CALOR Y HUMEDAD DEL ELEMENTO. EL INTERCAMBIADOR ES SIMETRICO DE MODO QUE PUEDE UTILIZARSE DE UN MODO O DEL OTRO.
