摘要
PM_(2.5)颗粒对室内空气品质的影响日益受到重视,可吸入的颗粒物对人体的健康造成直接的威胁。采用数值模拟的方法分析空调系统送风条件下,四种不同的通风方式对PM_(2.5)颗粒浓度及运动分布的影响。结果表明:四种通风方式中,顶送顶回方式下室内PM_(2.5)颗粒浓度最小,空气净化效果最佳。选择合理的通风方式,合理的气流组织,对于降低室内PM_(2.5)颗粒物浓度有着重要作用。
The influence of PM2.5 particles on indoors air quality has received growing attention. Particulate matter poses a direct threat to human health. This paper adopts the method of numerical simulation, and analyzes the influence of four kinds of ventilation patterns to the distribution and concentration of PM2. 5 particles under the air-conditioning system supply condition. The results shows that among four ventilation modes, upper air supply and upper air return mode can make the lowest indoor PM2.5 particle concentration and the best air purfieation effect. Choosing a reasonable ventilation and air distribution play a vital part to reduce PMz5 concentration indoor.
