Heat exchanging system

Abstract

A heat exchanging system including a heat exchanger element formed by stacking, in predetermined spaced relation, a plurality of thermally conductive partition plates, primary and secondary air streams being allowed to alternately flow through laminar spaces between the partition plates, and heat exchange being effected between the primary and secondary air streams while the primary and secondary air streams are cyclically switched. In accordance with different embodiments, the partition plates may be impermeable to moisture and be capable of accumulating moisture, (b) be moisture transmissive and hygroscopic, or (c) be impermeable to moisture and have no capability of accumulating moisture. In addition, in accordance with different embodiments, the direction of flow of the air streams can be such that (a) the alternate flows of both of the primary and secondary air streams are in the same direction, (b) the alternate flows of at least one of the primary and secondary air streams are in opposite directions, or (c) the alternate flows of both of the air streams are in the opposite directions. In this way, a high-efficiency total heat exchanging function or a high-efficiency sensible heat exchanging function can be obtained.
