捷达空调风扇控制线盒原理

捷达空调风扇控制线盒原理 捷达各车型空调压缩机及风扇的控制原 理 空调压缩机及风扇控制原理分析 夏季来临，经销商面临维修空调不制冷或电子扇工作不正常的故障越来越多，同时关于抱怨 维修时间长、费用高、一次修复不成功的案例越来越多，为了提高维修生产效率和故障判断 的准确性，特此整理了捷达各车型风扇控制器的控制原理。 个人认为空调不制冷首先分成两个大方向: 空调压缩机电磁离合器吸合——不制冷或制冷效果不好 空调压缩机吸合不制冷或制冷效果不好的故障基本上都是制冷循环的原因，主要集中在亏制 冷剂、压缩机、膨胀阀及蒸发箱赃污或鼓风机及风道等控制元件故障。这些故障很容易检查 和判断，在这里不做深入说明。 空调压缩机电磁离合器不吸合——不制冷 压缩机电磁离合器不吸合可以再细分为两个方向: A:压力不足(低于 2bar)导致的压缩机不吸合，这类故障可以划分到第 1 大类故障处理范 畴，即制冷循环问。 B:电路导致的空调压缩机电磁离合器不吸合——以下的文字及图片就主要阐述空调压缩机的 电磁离合器控制原理及吸合应具备的基本条件。电磁离合器的控制最终都是由风扇控制器控 制，那么我们实际上只要将输入和输出风扇控制器的信号研究透彻，就可以从容的应对压缩 机电磁离合器的控制和风扇的控制的相关故障，达到提高维修效率和一次修复率的目的。 以下就分别介绍各不同类型的风扇控制器原理及分析: 一:车 型:JETTA 5V AHP发动机 风扇控制器零件号:L357 919 506 A school)], 4 4 house building as well as more than 1000 copies of books, more than 10 kinds of collection of newspapers and magazines, fires burnt down.
