PURPOSE:To contrive to separately perform sensible heat exchange and total heat exchange at high efficiency in a single heat exchanger, by a method wherein a columnar rotor provided with moisture-nonpermeable moisture-absorptive partition walls stacked in a circumferential direction with a spacing therebetween is rotated, and a primary gas flow and a secondary gas flow are caused to alternately pass between the layers of the stack. CONSTITUTION:The primary gas flow A enters an element 1 through an outside peripheral part, and flows out through a left end part in the axial direction, while the secondary gas flow B enters an element 2 through an outside peripheral part, and flows out through a right end part in the axial direction. Since the heat exchanger is rotated, the primary gas flow A passes through the element 2 by entering through the left end part in the axial direction and flowing out through the outside peripheral part, namely, in the direction opposite to the direction in which the secondary gas flow B has passed through the element 2, while the secondary gas flow B passes through the element 1 in the direction opposite to the direction in which the primary gas flow A has passed. Namely, by rotating the elements, the gas flows passing through the elements 1, 2 can be exchanged. accordingly, since the partition walls 5 are formed of a moisture-nonpermeable material, sensible heat exchange is effected, and since the partition walls 5 are coated with a moisture-absorptive agent and due to the rotation, total heat exchange can be effected. |
