摘要
本文对南方某地下地铁车站出入口环境进行了测试研究。通过对出入口壁面温度,地面温度,空气温度以及室外空气参数的测试,分析了车站出入口产生结露现象的原因,并给出了相关工程措施建议。测试结果表明:出入口壁面、地面温度低于室外空气露点温度,是造成壁面与地面结露的主要原因。部分长出入口内设置风机盘管,其出风口温度较低,是造成吊顶凝水结露的主要原因。
The entrance and exit environment of an underground subway station in the south was tested and studied. By testing the wall temperature, ground temperature, air temperature and outdoor air parameters, the causes of condensation are analyzed. Relevant engineering measures and suggestions are given. The test results show that:(1) the temperature of the wall and ground at the inlet and outlet is lower than the dew point temperature of the outdoor air, which is the main reason for the condensation of wall and ground;(2) Fan coil units are set in some long inlets and outlets, and the low temperature is the main reason for dew condensation on the ceiling.
