Abstract

The main objective of this article is to investigate the difference in velocity field,temperature field and indoor CO_2 concentration distribution in a room based on the software of FLUENT when one air-conditioned room is subject to the displacement ventilation method and mixed ventilation method.The results show that the displacement ventilation method is better than mixed ventilation method in improve thermal comfort,indoor air quality and energy-saving.
