PURPOSE:To obtain the highly efficient heat exchanging device by a method wherein a cylindrical heat exchanger, formed by laminating a plurality layers of first and second elements along the circumferential direction through a partitioning plate having moisture permeating and absorbing properties so as to flow primary and secondary airflows between respective layers alternately, is rotated. CONSTITUTION:The first element 1 and the second element 2 are laminated alternately to form the cylindrical heat exchanger 6. The elements 1, 2 are constituted of a partitioning plate 3 having moisture permeating and absorbing properties, spacing plates between end surfaces and spacing plates 5 while moisture absorbing agent is coated or impregnated on the surfaces of these plates. The exchange of heat and moisture (humidity) between the primary airflow A and the secondary airflow B is effected through the partitioning plate 3 between both elements 1, 2. On the other hand, the heat exchanger 6 is being rotated and the primary airflow A and the secondary airflow B are interchanged alternately in both elements 1, 2 repeatedly, therefore, the full heat exchange may be effected in the same manner as in heat accumulating and rotating type heat exchanger. |
