Recently, membrane-based dehumidification having abilities of high water vapor permeability is regarded as emerging technology for heating, ventilating, and air-conditioning (HVAC) system. In this system, energy consumption can be reduced by using selectively water vapor permeable membrane extracting water vapor from the humid air without release of latent heat. We fabricated hydrophobic polymer based dense membrane incorporated with hydrophilic fillers and it was confirmed that the membrane has high water vapor permeable property using a standard method described in ASTM-E96. However, ASTM method does not provide sufficient information about the membrane performance for actual operating environments. In this presentation, we studied the water vapor permeable property of the membrane under various temperature and humidity conditions using a home-made chamber. |
