The Research And Practice Of The Solar Energy Utilization Of Railway Passenger Stations In High Altitude Areas

Railway station was born with the birth of railway,is engaged in the business for railway passenger transport and passenger traffic and servicing work place,is the place for passengers to take a fall,it is also one of the main building of a city,is closely related to the development of the city.The railway station becomes the hub of the city's three-dimensional transportation,and the quality of the railway station is higher.Now along with the passenger railway station transportation scale,to further improve the service quality and economic engine function,to the quality of the railway station also put forward higher request,also is bound to cause the passenger demand more energy consumption.The study on how to improve indoor comfort,reduce energy consumption and reduce the impact of environmental impact is particularly urgent for the special public buildings of large railway station.There is cold winter in the high altitude areas in the southwest of China.The temperature goes through big difference between daytime and night.The heating period is quite long and the heating resources are inadequate.However,the high rate of sunshine and the strong solar radiation make these areas become the best places to make use of the solar energy.The buildings of the stations along Lahsa-Linzhi Railway,Chengdu-Lanzhou Railway and other railways in Tibetan Plateau are only in need of heating in winter owe to the influence of regional natural condition.These places belong to high altitude cold regions,solar energy resources are extremely rich,he has passed so if can reasonable to design buildings,you can reach the standard of the basic indoor thermal environment.Currently,the methods of the heating supplies in these areas are making use of gas,oil,electric heating,Air source,water source heat pump system and so on.Due to the sparsely populated characteristic in these areas,a few people use the stations so that the cost per capita of using the traditional heating way is high.Through the relevant test data in Huangshengguan region,this paper seeks reasonable ways and modes of the solar energy utilization: achieving the optimumstrategy of solar energy utilization by rational arrangement of buildings' orientation and the choice of architectural form,material,construction and component.The main research methods used were field investigation,establishing BIM models to analyze sunshine and the solar radiation and using ECOTECT to analyze the energy consumption of the solar architectural model,which will achieve optimal application effects.That will help the space utilization and energy utilization of small railway passenger stations in these areas to acquire the best social,environmental and economic benefits,and to study the best heating scheme for Huang sheng guan.
