不同送风方式对室内负离子分布影响的数值模拟

采用计算流体力学方法,对混合通风、地板送风及置换通风三种工况下室内负离子的动态传播过程进行了数值模拟.通过对模拟结果进行讨论,分析了室内负离子的分布特征,结果表明,置换通风情况下负离子净化器比其余两种工况能更有效地控制房间较低位置(走动区或办公桌)产生的污染物,同时,当负离子净化器间歇运行时,置换通风工况需要最短的开机...

Numerical Simulation of Different Types of Ventilation's Influence on Indoor Negative Ion Spreading in Air

A simulation on the dynamic process of negative ion concentration among mixing ventilation,underfloor ventilation and displacement ventilation was conducted by using a Computational Fluid Dynamics(CFD) program.The results of an investigation simulation the distribution of negative ion in the three different types of ventilation indicate that displacement ventilation has a stronger impact on control the pollutants from indoor lower position(walking area or desk) than the other two kinds of ventilations,and w...
