| 摘 要： | 实验研究了室内初始温度对自然置换通风特性的影响。结果表明，实验舱内的初始温度越大，其热分层特性越明显，且最高测点与最低测点的温度差值越大。此外，室内污染物的分布和清除效率也受室内初始温度的影响，随着室内初始温度的升高，室内污染物的清除效率和房间上部区域的污染物浓度增大，同时房间上部与下部的浓度分层现象越明显。

| Abstract: | The characteristics of natural displacement ventilation process are experimentally studied.It is found that with the increase of the initial temperature of the room, the thermal stratification characteristics is the more obvious and the temperature difference of the highest point and lowest point is greater.In addition, the distribution of indoor pollutants and removal efficiency are affected by the initial temperature, removal efficiency of pollutants and the pollutant concentration in the upper of room will be higher if the indoor initial temperature is increased, simultaneously, the density stratification phenomenon between the upper and lower of room is more obvious. |
