冬季某地下通道自然通风的测定与分析

Measurement and Analysis of Natural Ventilation for an Underground Space in Winter

冬季,对某长通道式地下洞室的自然通风进行了的现场实测。通过监测和分析空气的温度、相对湿度、风速和围护结构表面温度,揭示了冬季在自然通风情况下,室外空气进入室内后温度和相对湿度的变化规律以及在洞室内部空气、围护结构及内部热源间的热传递关系。

In winter, make a measurement of a channel underground. The measured parameters include airflow＇s temperature, relative humid, velocity and temperature of wail. Based on the measurement and analysis, found the change rule of airflow＇s temperature and relative humid in the condition of outdoor air entering channel in winter. And found the heat transfer relationship among the indoor airflow, indoor heater and wall.
