Experimental study for humidification performance of air-to-water type hollow fiber membrane humidifier

In this study, a water-to-air type hollow-fiber membrane humidifier was built, and its humidification characteristics were experimentally investigated under various test conditions. A module made of porous in which hydrophilic polymeric raw materials are mixed used. Using the selected material, shell-and-tube structured fabricated tested operating The experimental data showed that proposed modules exhibited 74.5%–91.7% effectiveness moisture transfer 2.5–15.8 g/kg conditions; furthermore, could provide performance with few temperature changes. results parametric analysis indicated inlet water critical factor affecting heating system but did not show clear effect flow rate.
