摘要
基于对广州地铁站内气流温度、速度的实测,计算相应的相对热指标(RWI),发现虽然能够按照《地铁设计规范》要求,实现从室外到站厅、站台厅温度的递减,但RWI值波动较大,导致乘客在行进过程中无法获得"暂时舒适"。因此,提出根据室外逐时温度,给定适当的相对热指标差值,确定地铁站内夏季空调各时刻运行控制温度,以满足乘客的过渡性舒适要求。根据室外逐时温度变化及客流量的波动,计算地铁站台厅内夏季典型日逐时负荷及逐时送风量,提出夏季风机分时段改变运转速度或运行台数的运行方案。探讨两种极限热损失率(HDR)所对应的冬季地铁车站内的控制温度,提出冬季站台厅温度的调节范围。
Based on the measured air temperatures and velocities in Guangzhou subway station, the corresponding Relative Warmth Index （RWI） values were calculated. It was found that temperature reduced gradually from outside to underground hall and to platform. However, the RWI values fluctuated heavily and passengers were not “comfortable for the time being”. In order to find out suitable control temperature for a subway station, it is proposed that the control air temperatures of each zone, including underground hall and platform, at every hour, can be determined by specifying a suitable RWI difference and hourly outdoor air temperature and humidity, etc. Then passengers will be comfortable during transition. According to the obtained temperature, the air supply rates are calculated and operational modes of fans are put forward. In the end, two extreme cases of Heating Deficit Rate are studied and the control temperature range of subway station in winter is proposed.
