Potential energy savings for conditioning fresh air with a membrane-based energy recovery ventilator.

Author(s) : NIU J., ZHANG L.

Summary

A significant amount of energy is required to condition the ventilation air in a typical air-conditioning system. In hot and humid regions such as Hong Kong, latent energy recovery dominates the total energy recovery effects. High sensible effectiveness is insignificant unless the latent heat is recovered at the same time. With the membrane ventilator, both the sensible and the latent effectiveness remain relatively stable during the whole year. The amount of latent energy recovered annually is 6.9 times higher than that of sensible. The total energy savings amount to 21.5% of the cooling load.
