摘　　要：采用计算流体力学软件Fluent,数值模拟了空调房间在不同送风方式下的湿度分布,上送上回送风方式下空气的速度矢量分布及温度分布。研究表明:下送上回的送风方式下,湿度分层较为明显,梯度较大,人体活动区域的相对湿度较高。由上送上回的送风方式可见,研究平面内相对湿度分布规律会受空气速度及温度分布的强烈影响。Adoptingthe computational fluid dynamics software FLUENT, the article makes a numerical simulation of the humidity distribution under different air supply modes in air-conditioned room, and the velocity vector distribution and temperature distribution under the air supply mode of air supply mode of down-inlet and up-outlet, the humidity up-inlet and up-outlet. The article finds out that under the stratification is more obvious and the gradient is greater, and the air relative humidity of human activity region is lower. By the air supply mode of up-inlet and up-outlet, the article finds out that the relative humidity distribution laws will be strongly influenced by the distribution of air velocity and temperature.
