Case Study of Space Cooling and Heating Energy Demand of a High-speed Railway Station in China

摘要

As a new type of large-scale public building,high-speed railway stations are developing fast throughout China.In general,most of the newly built stations have large,tall and open space like waiting hall and ticketing lobby,with large area of glass curtain wall or skylight.Such features may contribute to higher energy demand of the stations,especially for HVAC system.In this paper,a medium-size high speed railway station in South China is taken as an example to study the HVAC load characteristics for such buildings.Based on measured data and relevant information,and with the help of simulation tool DeST,cooling and heating load of the station are calculated and broken down into several major parts,including fresh air load,solar radiation,internal heat and building envelop.Main features are identified for the whole station and its major spaces,and then corresponding energy saving approaches are proposed.
