【摘要】 本文采用数值模拟方法,对应用置换通风方式的一典型办公室房间的气流组织进行计算,并分析其速度场及温度场的分布特性。然后应用PPD、PMV及空气龄评价其舒适性。最后,得出结论:置换通风系统能够提供一个较好的热舒适环境并能提高室内空气品质。更多还原

【Abstract】 Adopts numerical simulation, calculates the air flow of a typical office which apply displacement ventilation, analyzes the characters of the distribution of field of velocity and temperature. Then, evluates its performance by PPD,PMV and THE AGE OF AIR, draws a conclusion that the displacement ventilation can maintain a thermally comfortable environment and provides better indoor air quality.更多还原
