Document Type and Number:
WIPO Patent Application WO/2020/045003
Kind Code:
A1
Abstract:
This heat exchange element (106) is configured by laminating heat exchange element pieces (115), each including a heat transfer plate (113) having heat transfer properties and a plurality of ribs (114) provided in parallel on one side of the heat transfer plate (113), such that layers of exhaust air ducts (116) and layers of intake air ducts (117) are alternately formed. The heat exchange element (106) allows for heat exchange between exhaust air currents (103) flowing through the exhaust air ducts (116) and intake air currents (104) flowing through the intake air ducts (117) via the heat transfer plates (113). The ribs (114) are formed from a plurality of fibrous members having hygroscopic properties and include protection layers (130) covering the end faces of the ribs (114).
