摘要
地铁空调系统的控制站厅和站台在设计温度值不变的设计运行模式下不能满足乘客舒适性要求,乘客的舒适感随新风状态变化而变化。由于乘客在站厅和站台的停留时间短,应根据相对热指标来评价非稳定条件下乘客的舒适性要求。本文在变风量调节的基础上,建立了按相对热指标来调节运行地铁中央空调系统的理论模型,在满足人体舒适性要求的前提下,解决了站台和站厅温湿度耦合问题。本文以广州地铁二号线新港东站为例,对比分析了空调系统相对热指标运行模式和设计运行模式下的舒适性和能耗等特点,为运行模式的完善提供了参考。
The design running work mode of subway air-conditioning system by controlling the temperature of the platform and hall could not satisfy passengers＇ thermal comfort. On the other hand, thermal comfort would be changed under different fresh air conditions. Because the stay period for passengers in platform and hall was relatively short, the thermal comfort should be evaluated by relative warmth index （RWI） under unsteady condition. In this paper, the theory model of running the subway air-conditioning system based on VAV technology was established, the couple problem of temperature and RH in platform and station hall would be solved and the thermal comfort level would not be influenced at the same time. Taking Xingangdong Station of Guangzhou No .2 subway as an example, the characteristics of thermal comfort and energy consumption under RWI and design running modes for air-conditioning system were analyzed.
