摘　　要：深部地铁车站的冷却水管道需经过百米长的通廊,冷却水水温会受到通廊热环境影响发生变化,进而对冷却塔和冷水机组的运行造成影响。为了更好地对冷却塔和冷水机组的运行效果进行优化,针对冷却水系统在长距离管道通廊中的传热特性进行了分析。通过建立的管道通廊简化传热模型,综合考虑了冷却水管与通廊空气及围壁之间的热交换过程,分析了供冷季下冷却水经过通廊后的温度变化及换热情况。采用TRNSYS软件对具体案例进行模拟,结果表明,在供冷季,冷却水供水管、回水管经过通廊后的温降最高可达0.24℃、0.18℃,总散热量最高可达38.9kW。The cooling water pipes in deep subway stations need to pass through a 100-meter-long passageway,and the water temperature will change due to the thermal environment of the passageway,which will affect the operation of the cooling tower and chilled water unit.In order to better optimize the operation of the cooling tower and chilled water unit,this paper analyzes the heat transfer characteristics of the cooling water system in a long-distance pipe passageway.By establishing a simplified heat transfer model of the pipe passageway,the heat exchange process between the cooling water pipe and the passageway air and wall is comprehensively considered,and the temperature change and heat exchange of the cooling water after passing through the passageway are analyzed in the cooling season.The simulation results of a specific case using TRNSYS software show that in the cooling season,the maximum temperature drop of the cooling water supply pipe and return pipe after passing through the passageway is 0.24℃and 0.18℃,respectively,and the total heat dissipation is up to 38.9kW.
