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。
Subway air-conditioning system control station hall and platform in the design temperature value of the design mode of operation can not meet the passenger comfort requirements, passenger comfort with the status of the changes in fresh air changes. Due to the short stay time of passengers in the station hall and platform, the comfort requirements of passengers under unsteady conditions should be evaluated according to the relative thermal index. In this paper, based on the variable air volume adjustment, a theoretical model for adjusting the operation of the central air-conditioning system of the subway is established according to the relative thermal index. Under the premise of meeting human comfort requirements, the problem of temperature and humidity coupling between the platform and the station hall is solved. Taking the Newport East Station of Guangzhou Metro Line 2 as an example, this paper comparatively analyzes the relative thermal index operation mode and the comfort and energy consumption under the design operation mode of air conditioning system, and provides a reference for the improvement of operation mode.
