通过对上海地铁7号线岚皋站排热风机在冬季的实际测试,分析了冬季情况下排热风机系统对应隧道内温度、站台站厅内部温度的影响,最终得出相关结论,证明排热风机在冬季情况下,以间隔时间段内夜晚开启可以降低隧道积热积湿,并且不会影响地铁白天正常运行期间地铁站内的候车环境。同时为制定排热风机相关控制策略提供相应数据理论依据。
Through the actual test of the exhaust heat fan of Langao station in Shanghai Metro Line 7 in winter, the influence of the temperature inside the tunnel and the temperature inside the station and station of the exhaust fan system in winter are analyzed. The conclusion is reached that the heat exhaust fan In winter, opening at night at intervals can reduce the accumulation of heat and moisture in the tunnel and will not affect the waiting environment inside the subway station during normal daytime operation of the subway. At the same time to provide relevant control strategies for exhaust fan to provide the appropriate data theory.
