Title:
HEAT EXCHANGE ELEMENT AND HEAT EXCHANGE-TYPE VENTILATION DEVICE USING SAME
Document Type and Number:
WIPO Patent Application WO/2020/174721
Kind Code:
A1
Abstract:
A heat exchange element (106) is obtained by stacking heat exchange element pieces (115) each provided with a heat transfer plate (113) having heat transfer properties and a plurality of ribs (114) disposed on one surface of the heat transfer plate (113) so as to form alternately a single layer of a discharge air passage (116) and a single layer of a supply air passage (117), so that heat exchange is performed via the heat transfer plate (113) between a discharge air flow (103) flowing through the discharge air passage (116) and a supply air flow (104) flowing through the supply air passage (117). The heat transfer plate (113) and the ribs (114) are adhered to each other with an adhesive member. The ribs (114) are each formed from a plurality of fiber members having hot-melt properties and hygroscopic properties. The ribs (114) each have a fiber melt layer formed by melting and adhering the plurality of fiber members onto the surfaces of the ribs (114).
