列车空调节能技术研究

Research on Energy-saving Technology for Train Air Conditioning System

我国轨道交通发展迅速,列车空调作为列车主要辅助设备,能耗占比较大,其节能性受到广泛关注。列车空调受到安装空间限制,且运行环境恶劣,应用场景具有载客量变化显著、车外气象参数实时变化和车门频繁启闭等显著特点,都将对列车空调造成影响。文章对目前列车空调节能技术研究进行调研,从节能空调控制技术、低能耗空调机组技术、列车空调热泵技术等3个方面进行归纳总结,并在此基础上提出列车空调节能技术的研究重点和发展方向,对列车空调节能技术的开发具有一定参考作用。

China's rail transport industry has developed rapidly.As the main auxiliary equipment for trains,air conditioning system accounts for a large proportion of energy consumption,and its energy-saving performance has received widespread attention.Train air conditioning system is limited by installation space,and its operating environment is harsh.The application scenarios have significant changes in passenger capacity,real-time changes in external meteorological parameters,and frequent opening and closing of train doors,all of which will have an impact on the air conditioning system.The article researches on the current energy-saving technology of train air conditioning system,and summarizes it from three aspects:energy-saving air conditioning control technology,low energy consumption air conditioning sets technology,and train air conditioning heat pump technology.Based on this,it proposes the research focus and development direction of train air conditioning energy-saving technology,which has a certain reference value for its development.
