摘要
为进一步研究有效的技术措施以降低室内有机污染物,对3种不同的空调送风方式下的室内甲醛浓度分布进行研究。结合甲醛气体送风换气衰减法净化甲醛气体,探究送风方式和送风速度对甲醛浓度衰减的作用关系。采用CFD方式开展了不同送风方式对室内甲醛衰减的气流组织数值模拟研究,进行了送风速度对甲醛去除效率的影响研究。研究表明,空调送风可以有效去除室内甲醛,其中孔板送风模式在人体休息时呼吸区域即距离地面0.5m处室内空气品质最优;送风速度与室内甲醛浓度的去除率成正相关。
In order to provide a reference for further research on effective technical measures to reduce indoor organic pollutants,the indoor formaldehyde concentration distribution under three different air supply modes was studied.In combination with formaldehyde gas ventilation and ventilation attenuation mode to purify formaldehyde gas,the effects of air supply mode and air supply speed on the attenuation of formaldehyde concentration were investigated.The CFD method was used to carry out the numerical simulation study on the effect of different air supply modes on air distribution for indoor formaldehyde attenuation,and study the effect of air supply speed on the removal efficiency of formaldehyde.Studies show that air conditioning air supply can effectively remove indoor formaldehyde,and in the orifice air supply mode,the quality of indoor air is the best in the breathing area of human body when the human body is resting,that is,at the height of 0.5 m above the ground;the air supply speed is positively related to the removal rate of indoor formaldehyde concentration.
