摘要
武汉地铁车站排热风机运行时间为每日4:00-24:00,运行时间久,能耗大。测试了某地铁站排热风机在现行运行模式下车站隧道轨行区的温湿度和CO2浓度参数,测试结果均优于地铁设计规范要求,据此提出了排热风机两种节能运行模式,即模式一:列车正常运行时关闭车站一端的排热风机;模式二:列车正常运行时车站两端排热风机隔天运行。进一步对这两种节能运行模式进行了相应的测试,测试结果表明相关运行参数满足地铁设计规范要求。排热风机的这两种节能运行模式相对于现行运行模式,综合节能率为50%。
Heat extraction fans in subway stations in Wuhan runs daily for a long time from 4 o’clock to 24 o’clock resulting in high energy consumption.This paper tested the environment parameters including temperature,humidity and CO2 concentration of the station tunnel track area of a station under the present operation mode of the heat extraction fan.The test results shows the measured environment is better than the requirement of the design specification.To reduce the energy consumption of the heat extraction fan,two energy-saving operation modes are proposed,i.e.,mode 1 and mode 2.The energy-saving operation mode 1 is that the heat extraction fans at one end are off when the subway station is in normal operation,and the energy-saving operation mode 2 is that the heat extraction fans at both ends are on each other day when the subway station is in normal operation.The environment parameters under these two modes are also tested,and the results show they meet the requirement of the design specification.When compared with the present operation mode,both energy-saving operation modes can save energy consumption up to 50%.
