ABSTRACT
ABSTRACT: This paper choose a typical air-conditioned room as a research target, making use of Computational Fluid Dynamics to research the distribution of airflow organization under different positions of air inlet and air outlet. Establish the mathematical models of different vent positions to proceed numerical simulation. The distributions of vent positions are as follows, the upper vent sends air and the lower vent returns air in the same side, the upper vent sends air and the lower vent returns air in the opposite side, the upper vent sends air and the upper vent returns air in the same side, the upper vent sends air and the upper vent returns air in the opposite side. It can obtain the computation results of the indoor airflow velocity field and temperature field under four kinds of vent positions. Through comparative analysis, it finds that the best vent position is the upper vent sends air and the lower vent returns air in the same side.
