摘要
分析了铁道客车空调机组在车辆运行过程中的通风量和冷凝风量的变化及对制冷量的影响,由此解释了空调机组运行故障的原因。针对车辆段客车空调机组检修试验中存在的问题,提出了要结合车辆运行和静态两种工况进行模拟试验的观点,并对具体的试验方法进行了讨论。
The variations of fresh air vohane end condense air vohane as well as its influence on performance of train air - conditioning unit are discussed in this paper, which cause air- conditioning unit in moving condition-maybe. There are some problems in train air- conditioning unit＇s maintenance test because the performance of air - conditioning unit is different when the train is running or quiescence. In order to resolve these problems, a point that simulation experiments on the air- conditioning unit should be done in these two different situations respectively is put forward, and some concrete ways are studied in this paper.
