HEAT EXCHANGE MEMBRANE AND HEAT EXCHANGE ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide a heat exchange membrane, and a heat exchange element for improving basic performance and manufacturing performance, having high durability even in an environment of repeatedly causing dewing and drying, and generating no stimulative smell in the heat exchange element used for a heat exchange type ventilating fan. SOLUTION: A partition plate 2 of the heat exchange element 1 is composed of the heat exchange membrane 16 for joining a water insoluble no-binder porous sheet 15 molded on both surfaces of a moisture permeable resin film 14 without using an adhesive by a heat seal. The heat exchange element 1 is formed as a heat exchange plate 5 by integrally molding two sets of resin shielding ribs 3 arranged in respectively opposed both end parts of the obverse and the reverse of the partition plate 2 and a plurality of resin interval ribs 4 arranged at a prescribed interval in parallel to these shielding ribs 3 so as to be orthogonal on the obverse and the reverse of the partition plate 2. The moisture-proof heat exchange membrane and the heat exchange element are obtained by multi-layering these heat exchange plate 5 and partition plate 2 alternately. COPYRIGHT: (C)2004,JPO
