摘要
采用CFD方法,对高大空间工业厂房空调系统采用两种不同的气流组织(复合型置换通风、喷口送风)进行计算,并分析两种气流组织的速度场和温度场的分布特性,应用PPD、PMV及空气龄等评价其舒适性和可行性,最后得出结论:置换通风能够为高大空间工业厂房提供一个较好的热舒适性环境,并能提高车间内空气品质。
Adopts numerical simulation, calcuhtes the air flow of mixed displacement ventilation and horizontal directing jets in large space building, analyzes the characters of the distribution of field of velocity and temperature. Then, cvluates its performance by PPD, PMV and The age of air, By contrast, draws a conclusion that the mixed displacement ventilation can maintain a thermally conffortable environment and provides better indoor air quality for large space building.
