摘　　要：空调机组是通过调节客室温度提高列车舒适性的重要装置,也是列车能耗的主要部件之一。目前轨道车辆空调机组主要分为定频空调和变频空调2种;定频空调是根据客室内热负荷的需求,压缩机以固定转速运转,通过启停压缩机改变制冷量输出,实现客室温度调节;变频空调是根据客室内热负荷的需求,通过变频器控制压缩机的转速,提供线性可变制冷量输出,实现客室温度调节。文章分析了25G、25T型铁路普速客车空调的应用现状,详细介绍了铁路普速客车上定频空调改造成变频空调的技术方案以及验证情况,结果表明,变频空调技术提高了铁路普速客车的舒适性并且节能,优势明显,建议推广。The air conditioning set is an important equipment for improving the comfort of the train by adjusting the temperature in the passenger compartments and is one of the main energy-consuming components of the train.At present,the air conditioning sets of rail vehicles are mainly divided into two types:the fixedfrequency air conditioner and the inverter air conditioner.The fixed-frequency air conditioner can adjust the temperature in the passenger compartments by starting or stopping the compressor running at a fixed rotating speed to change the cooling capacity output according to the demand for thermal load in the passenger compartments;while the inverter air conditioner can adjust the temperature in the passenger compartments by controlling the rotating speed of the compressor with the frequency converter to provide a linear and variable cooling capacity output according to the demand for thermal load in the passenger compartments.This article analyzes the current application status of the air conditioners for railway passenger cars running at ordinary speed of types 25G and 25T,introduces in detail the technical solution for transforming the fixed-frequency air conditioner into the inverter air conditioner in the railway passenger cars running at ordinary speed and its verification situation.It turns out that the technology of inverter air conditioner has improved the comfort of these railway passenger cars running at ordinary speed and saved the energy and has clear advantages,so it’s recommended to generalize this technology.
