Recently membrane-based energy exchanger has drawn substantial attention due to its high performance for heat and moisture transfer. Because much research revealed that carbon nanotube (CNT) has strong transport ability in several fields like water filtration, sea-water desalination and water collection due to its unique properties, we try to apply CNT in heat exchanger for heat recovery in buildings. In this paper, we primarily compare the heat transfer properties of CNT-based membranes produced by us with that of other membranes in test rigs. The effect of inlet temperature on the heat transfer characteristics of CNT is then investigated. Results show that the total heat transfer coefficient of the CNT does not change significantly with the change of the inlet air temperature and the average heat transfer coefficient of the CNT is 49.11 W•m-2•K-1.
