Urban rail transit plays an important role in solving traffic congestion problems,optimizing urban functional configuration,and improving residents'travel environment,etc.However,as a"large energy user",urban rail transit needs a lot of energy.In recent years,with the"Dual-Carbon Goals"(realizing carbon peak before 2030 and carbon neutrality before 2060)in China,the development of green and low-carbon urban rail has become a consensus.The energy consumption of ventilation and air conditioning system accounts for 50%~60%of the operating energy consumption in metro station,and energy saving measures is of great significance for green low-carbon urban rail and its energy efficiency.Based on experience of engineering design,the running status and problems existing in the urban rail air conditioning system are analyzed,combined with specific energy-saving design of large system,small system,multi-online system and air conditioning water system,discussing the main energy-saving measures and the development direction of energy-saving technology from the aspects of equipment and system configuration.
