京张高铁清河站电热风幕节能措施研究

Research on Electric Air Curtain Energy-saving Measures for Qinghe Station on Beijing-Zhangjiakou High-speed Railway

寒冷地区的高铁站房,电热风幕在空调系统能耗占比较大。既有高铁站房的电热风幕,从设计到实际使用,均为人工就地控制,能源浪费较大。结合京张高铁清河站设计实例,提出高铁站房电热风幕可采取的主动节能控制措施。根据电热风幕工作原理,分析不同气温和客流量下清河站电热风幕可对应的工作状态。并依据2016~2017年北京市供暖季的日气温,模拟比较采取节能措施前后,清河站一个采暖季的电热风幕能耗状态。通过模拟对比分析后,得出采取节能措施后,清河站电热风幕能耗显著下降,达到节约能源的目的。该项节能措施已在京张高铁全线各站中使用,实际节能效果待站房全面投入使用后进一步验证。

In the cold area station,the energy consumption of the electric hot wind curtain in the Heating,Ventilation and Air Conditioning system(HVAC)is relatively large.The electric air curtain of the existing station is controlled manually and locally from design to practical use,resulting in a great waste of energy.This paper,combining with the design of Qinghe Railway Station on Beijing-Zhangjiakou High-speed Railway,proposes initiative energy-saving measures of electric air curtain(EAC)for High-speed Railway station,and analyzes the working conditions of the EAC of Qinghe Railway Station subject to different temperatures and passenger flows according to the operation principle of EAC.The energy consumption state of EAC of Qinghe Railway Station in the heating season is simulated and compared before and after adopting energy saving measures based on the daily temperature of the heating season in Beijing during 2016~2017.The comparative analysis shows that energy consumption is reduced with the presence of the energy saving measures and the goal of energy saving is achieved.The energy saving measures have been applied in all stations on Beijing-Zhangjiakou High-speed Railway,and the actual energy saving effect will be further verified when the stations are fully put into use.
