铁路客车空调机组制暖故障探讨

Discussion on Heating Fault of Air Conditioning Unit in Passenger Train

通过实例阐述,讨论了铁路客车空调机组超温保护疑难故障的原因,从理论上论证了空气预热器发热元件表面翅片的安装强度对热量扩散能力以及空调机组控制系统的影响。

This paper discusses the causes of the malfunction of the over-temperature protection in the air conditioning unit of railway passenger trains, and theoretically demonstrates the influence of the installation strength of the fin on the heat diffusion capacity and the control system of the air conditioning unit.
