地铁热环境研究对于地铁空间布局设置合理性与节能运行具有重要意义,针对高寒地区城市地铁空间布局的热能效应进行相关研究。首先分析了高寒地区城市气候特征与地铁空间布局要素,给出了高寒地区城市地铁空间的主要功能;针对其气候的特殊性,分析了地铁出入口的温度缓冲布局,空间逐层增温的主要技术手段,以及乘客的热舒适感受温度、湿度及气流速度的范围;通过地铁空间建筑围护结构的传热、空间内人员的人体散热,以及隧道屏蔽门玻璃传热分析高寒地区城市地铁空间的热能效应。通过仿真,验证了城市地铁空间热量变化与空调设备运行及隧道空间热量的关联性,在地铁空间热能效应调节过程中应进行综合考虑,并采取措施进行针对性调控。
The research on thermal environment of metro is significant for the space layout rationality of metro and the energy-saving operation. The thermal energy effect of urban metro space layout in alpine region was researched. Firstly, urban climate characteristic and metro space layout element in alpine region were analyzed, and main functions of urban metro space in alpine region were given. According to the particularity of climate, the temperature buffer layout of subway entrance and subway exit, main technical means of increasing temperature layer by layer in space, passenger’s thermal comfort, and the range of temperature, humidity and airflow speed were analyzed. Through the heat transfer of building envelope in subway space, the heat dissipation of human body in space, the heat transfer of glass of platform screen doors and the thermal energy effect of urban subway space were analyzed. Simulation results prove the correlation among the thermal change of urban subway space, the operation of air-conditioning equipment and the heat of tunnel space. In the process of adjusting the thermal energy effect of subway space, it is necessary to comprehensively consider this correlation.
