<P>PROBLEM TO BE SOLVED: To effectively suppress clogging due to frost formation, in a heat exchange element and a heat exchange ventilator using the same. <P>SOLUTION: A heat exchange element 1 includes a plurality of permeable films 2, and ribs 3 retaining an interval between the permeable films 2, and the permeable films 2 and the ribs 3 are stacked so that exhaust flues 4 and air supply flues 5 are alternately formed one by one roughly orthogonally to each other. As a height of the exhaust flue 4 is increased from an outlet (SA) side of the air supply flue 5 to an inlet (OA), the clogging due to frost formation can be effectively suppressed. <P>COPYRIGHT: (C)2013,JPO&INPIT |
