摘要:
［目的］针对地铁站能耗持续增长的态势，为准确评价当前地铁站用能水平，挖掘节能潜力，推动建筑节能工作，需要对屏蔽门地铁站的通风空调合理能耗修正。［方法］采用能耗原理模型，系统性地建立了各气候区地铁站的合理能耗基准。针对寒冷地区、夏热冬冷地区和夏热冬暖地区等不同气候区的典型城市，模拟得到了基准工况下的屏蔽门地铁站通风空调系统能耗约束值和引导值。考虑到各地气候差异和车站服务状况的差异，定量分析了气候条件、客运量、发车对数和隧道长度对地铁站通风空调合理能耗的影响程度，进而提出了各气候区不同城市、不同服务状况的屏蔽门地铁站通风空调系统合理能耗的修正计算方法。［结果及结论］气候条件中年平均湿球温度与能耗的相关性最高，相关系数R2为0.950；年总客运量从500万人次增加到1 100万人次，各气候区合理能耗指标增加2.2%~2.9%，各气候区之间差异不大；日总发车对数从140对增加到310对，各气候区合理能耗指标增加了2.0%~7.4%，不同气候区之间具有明显差异；隧道长度1 200 m的车站比800 m的车站，合理能耗指标高1.5%~4.9%，不同气候区之间具有明显差异。

［Objective］ In view of the continuous growth of energy consumption in metro stations, in order to accurately evaluate their current energy consumption level, tap energy conservation potential and promote energy conservation of buildings, it is necessary to revise the reasonable energy consumption of ventilation and air-conditioning in platform screen door metro stations. ［Method］ Based on the principle model of energy consumption, the reasonable energy consumption benchmark for metro stations in various climate areas is established systematically. For the typical cities in different climate areas including cold area, hot summer and cold winter area, hot summer and warm winter area, the energy consumption constraint value and guiding value of the ventilation and air-conditioning system in platform screen door metro stations under basic working conditions are obtained by simulation. In consideration of the climate differences and station services in different areas, the influence intensity of climate conditions, passenger volume, the number of train departures and tunnel length on the energy consumption of metro station ventilation and air-conditioning system is quantitatively analyzed.The revised calculation method is proposed for reasonable energy consumption of ventilation and air-conditioning system in metro stations with platform screen doors under different service conditions and in different cities and different climate areas. ［Result & Conclusion］ The annual mean wet-bulb temperature in climate conditions is highly correlated with energy consumption，showing a correlation coefficient R2 of 0.950. The reasonable energy consumption indicator of each climate area increases by 2.2% to 2.9% when the annual total passenger volume increases from 5 million to 11 million, showing little difference among climate areas. The indicator increases by 2.0% to 7.4% when the number of daily total departure trains increases from 140 to 310 pairs, showing obvious difference between different climate areas.The indicator of stations with a 1200 m long tunnel is 1.5% to 4.9% higher than that of stations with a 800 m long tunnel, showing obvious differences between different climate areas.
