通过对埋深约250m的北京SSL地下水电站交通洞换热特性5d的连续现场实时监测,分析了洞内空气温度随距洞口距离的变化规律及交通洞的节能潜力,测试结果表明地下交通洞对送风空气有明显的降温和升温效果。测试发现夏天1000m温降最大约达6℃,温升近3℃;每km最大供冷能力可达380kW以上,供热能力达140kW以上,且在交通洞末端靠近主厂房处温度维持在约23℃,北京SSL水电站利用地下隧洞节能潜力巨大,在夏季及冬季可以部分或全部替代空调冷热源,具有显著节能意义。
Through continuous on-site real-time monitoring of the traffic heat exchange characteristics of Beijing-Hong Kong SSL underground water station with a depth of about 250 m, the variation law of the air temperature in the tunnel with the distance to the tunnel and the energy saving potential of the traffic tunnel are analyzed. The test results show that the underground traffic tunnel Supply air has obvious cooling and heating effect. It is found that the maximum temperature drop of 1000m in summer is about 6 ℃ and the temperature is about 3 ℃. The maximum cooling capacity per km is 380kW and the heating capacity is more than 140kW. At the end of traffic tunnel, the temperature near the main plant is about 23 ℃, Beijing SSL hydropower station underground tunnel with great potential for energy saving, in summer and winter can be part or all of the replacement of air-conditioning heat and cold, with significant energy saving significance.
