摘　　要：地铁列车内送风是否均匀直接影响着车内乘客的舒适性,合理的送风道结构是保证送风均匀的前提条件。本文从列车空调送风道的均匀送风原理出发,对现有地铁列车上4种常见均匀送风风道的送风形式做了介绍,分析了各种风道的结构特点、影响各种送风道送风均匀性的因素以及使用受到限制的原因。并对现有车辆的风道优化方案做了简单介绍,提出以后对风道进行设计优化的方向。最后用fluent对比了条缝式静压送风主风道的两种送风方式的送风均匀性,发现主风道采用孔口送风的送风均匀性优于连续条缝。Whether the air supply to rail transit vehicles is uniform or not will directly affect the thermal comfort condition of passages inside the car. To ensure the uniform air supply, we must chooseproper air ductsfor different types of rail transit vehicles. This article presents the introduction of uniform air supply system theory and four common air supply air ducts on the existing rail transit vehicles. Then, it analyzes the structure characteristic of these four air ducts, and the factors affecting the uniformity of air supply, and the reasons why they are restricted to be used. Then several uniform air supply ductsoptimization methods on the existing rail transit vehicles are briefly introduced, and the direction of uniform air supply ductsoptimization is put forward. Finally, it compares two methodsof air supply for the main air duct used inSlit type static pressure air supply duct, with the FLUENT method, and finds that when the main air duct use perforated plate to deliver air to the static pressure duct, the uniform air supply is better than using continuous slit.
