本文简要叙述了广州铁路局空调客车的发展历史,对空调客车和空调机组的概况作了介绍。重点对分装式空调机组和单元式空调机组进行了对比,利用大量统计数字来说明其故障、制冷剂消耗量和配件更换量等各项经济指标。作者认为单元式空调机组具有明显的经济效益,作为我国铁路客车主型空调机组是比较合适的。同时,希望进一步统一品种和系列化,以加快铁路空调客车的发展。
This article briefly describes the history of the development of air-conditioned buses in Guangzhou Railway Administration and introduces the general situation of air-conditioned buses and air-conditioning units. Focus on the split-type air-conditioning unit and unit-type air-conditioning units were compared using a large number of statistics to illustrate its failure, refrigerant consumption and replacement parts and other economic indicators. The author believes that unit air-conditioning unit has obvious economic benefits, as China’s main railway passenger air-conditioning unit is more appropriate. At the same time, I hope to further unify the variety and serialization to speed up the development of railway air-conditioned buses.
