Abstract：
Analyses the particularity of indoor environment in underground railway stations, summarizes the air conditioning load structure and discusses the changing characteristics of the air conditioning load. By analysing the design situation and operation situation of air conditioning systems in underground railway stations, reveals the existing problems and uncovers the cause of the subcooling phenomenon in underground railway stations. Combined with actual project analysis, puts forward the method to solve the mismatching problem between the refrigerating capacity of air conditioning plants and the load demand, gives some energy saving operation management measures, and calculates energy saving potential of the air conditioning system in underground railway stations.
