<p>A heat exchanger element, wherein a plate heat exchanger (16) is provided with spacers (13a, 13b) and a plurality of air duct ribs (13c), and in which an air exhaust unit, forming a plurality of air exhaust ducts, and an air supply unit (13), forming a plurality of air supply ducts, are layered. Moreover, the air exhaust flow and the air supply flow (5) orthogonally intersect or obliquely intersect at both ends (30) of the air exhaust duct and the air supply duct (15), and face in the center portion (31). In addition, the air supply duct (15g), closest to the inlet side of the exhaust air flow of the plurality of air supply ducts (15), is an enclosed region.</p> |
