Advanced Composite Membranes for Water Vapour Separations

Membrane based energy recovery ventilation (ERV) is now a key component of most energy efficient modern buildings. The ERV market is estimated to grow to $3.8B by 2022. ERVs improve the indoor air quality of buildings through ventilation and reduce the energy cost of ventilation by using building exhaust air to pre-condition fresh building supply air. In cooling conditions heat and humidity are removed from the incoming air and in heating condition heat and moisture are added to the incoming air. The membrane in the device allows the transport heat and moisture without transport of other gases and contaminants from the exhaust air to the supply air. Current polymeric membrane ERV technology is durable and has moderate performance, but new materials are required to further increase the membrane vapour transport performance and function to make more efficient devices.
