In this thesis, a performance analysis for an actual application of a hollow-fiber membrane (HFM)-based dehumidification system is investigated. Experimental tests and simulations on the application of the system were conducted. Further, basic data were suggested by testing and analyzing the HFM unit, module, and array, to determine the basic performance of the HFM-based dehumidification system. Also, considerations for its expansion into a system were examined. In addition, parameters that change the performance of the HFM-based dehumidification system were identified. The energy demand of the HFM-based dehumidification system was performed additional simulation for different load scales and usages. Also, its dehumidification efficiency was compared with cooling-based dehumidification systems. This results can be used as the base data for actual system designs. Major and minor variables affect the performance of membrane-based dehumidification systems. The major variables include the temperature, humidity, pressure difference, and available area, whereas the minor variables include the header loss, vacuum pump efficiency, and pressure loss during pipe installation. The results of this study show that as the temperature increases, the water flux, dehumidification rate, humidity, and pressure difference increase. However, with an increase in the available area, the water flux decreases, while the dehumidification rate increases.
