Assoc Prof Chua and his team are recognised globally for their research endeavours on membrane and adsorbent dehumidification for air conditioning applications in the tropics. The researchers’ award-winning paper describes the development of a hybrid solution that markedly improves air dehumidification. It comprises the integration of a composite desiccant and a nano-woven membrane for air dehumidification. The solution complements any building space’s needs, where removing moisture from the air via an energy-efficient means is a key concern.

Compared to existing commercial desiccant dehumidifier, the hybrid system requires a lower regenerating temperature, while producing air of very low humidity. The proposed hybrid solution involves the composite desiccant and membrane to work hand-in-hand to achieve enhanced moisture removal efficiency and improved energy efficiency by up to 40% compared to the best grade commercial dehumidifier. This work has been highly impactful in the area of air conditioning in megacities. When widely deployed, this “game-changing” disruptive hybrid dehumidification technology will raise the quality of life of citizens, making cities become distinctive global “green” cities.
