Résumé

Recent advances have introduced ionic membranes that can provide high water permeability in heating, ventilation, and air conditioning (HVAC) applications. These materials can be useful in many applications to help provide more efficient building technologies and higher indoor air quality through devices such as ionic liquid heat pumps (ILHPs), ionic liquid desiccants (ILDs), and energy recovery ventilators (ERVs). Water transmission mechanisms behind the water transport is not well understood, since different ionic membranes provide transmission in different ways. Water transportation can be a function of ionomer structure via the building blocks of the backbone, or from the functional groups on the side chains or from subtle features in membrane design and composition. In this work, we studied the permeation properties of different advanced ionic membranes. Membranes that show high water selectivity, and permeabilities exceeding 2*10-5 g/(s*m^2*Pa) are presented. High performance membranes are identified for optimum applications for different HVAC systems.
