EFFECT OF CORRUGATION ANGLE ON THE MOISTURE TRANSFER AND PRESSURE DROP FOR HUMIDIFYING ELEMENT MADE OF CELLULOSE AND PET
ABSTRACT
In this study, new humidifying element samples were made, and the moisture transfer and pressure drop characteristics were investigated. Results show that the new sample (cellulose 50% and PET 50%) yielded superior moisture transfer and pressure drop performance than the currently widely used GLASdek (glass wool) and CELdek (cellulose). The jm factors of the new sample are 33%−39% larger than those of GLASdek and 3.2%−13% larger than those of CELdek. On the other hand, f factors of the new sample are 0%−44% smaller than those of GLASdek, and 4.0%−35% larger than CELdek. In general, the jm or f factor increased as corrugation angle increased. The moisture transfer efficiency index (jm/f1/3) was the largest for a 15°/15° sample, followed by 30°/30°, 45°/45°, 15°/45°, and 60°/60° samples. Correlations are developed to predict jm and f factors of the samples having different corrugation angles.
