汽车手动空调常见故障与检测 摘要：随着汽车技术的发展，人们对汽车的舒适性有了更高的要求，汽车空调的出现提高了驾驶员和乘客随着汽车技术的发展，人们对汽车的舒适性有了更高的要求，汽车空调的出现提高了驾驶员和乘客的舒适性，并且在冬夏两季成为了不可缺少的现代汽车基本配备之一。汽车手动空调随着人们对舒适性的要求，技术设备的发展也越来越复杂化，这使得出现的故障也越来越多，这也对汽车空调的维修人员有了很高的要求。本文针对汽车手动空调的常见故障进行简析和研究，对今后的维修的故障问题查找起到了快捷的作用，本文从实际出发，对各个故障进行实践研究，并且认真做好记录，探讨出一系列的解决方法，解决了一些常见而又复杂的故障难题。 关键词：手动空调；常见故障；检测； Abstract: with the development of automotive technology, people have higher demands for car comfort, appearance of automotive air conditioning improves the driver and passengers to Abstract: with the development of automotive technology, people have higher demands for car comfort, appearance of automobile air conditioner to improve driver and passenger comfort, and in the two seasons of winter and summer has become the indispensable basic equipped with one of the modern automobile. Automobile air conditioning manual as people need comfort, the technology development of equipment becomes more and more complicated, which makes failure more and more, this is also the automobile air conditioner repair personnel have the very high request. This paper analyzed and studied according to the common faults of manual air-conditioned car, fault finding problem for future repair plays a quick action, this article embarks from the reality, conducts the practice research of each fault, and conscientiously do a good job record, explore a series of solutions, to solve some problems of common and complex.Keywords: manual air conditioning; common fault; detection; 目录 前言 从2年代汽车空调诞生以来，伴随汽车空调系统的普及与发展，汽车空调的发展大体上经历了五个阶段：单一取暖阶段、单一冷气阶段、冷暖一体化阶段、自动控制阶段、计算机控制阶段。作为汽车空调系统的控制方面也再不段的更新改进，同时，我国汽车空调的安装随着汽车业的发展以达到100%的普及性，空调已成为现代汽车的一向基本配备。给汽车空调的使用与维修问题带来新的挑战。最后通过对汽车空调故障检，对汽车空调系统深入探讨，以达到对汽车空调系统的了解，并运用在实际中。 四 膨胀阀的常见故障与实例检测 图4-1 4.2膨胀阀常见故障案例与检测 ·故障现象：一辆2005年生产的一汽马自达6 2.0L的轿车，发动机怠速运转正常，怠速时空调系统工作正常。但车辆行驶时，发动机动力不足，当车辆加速时，空调压缩机频繁重复结合、分离，且空调系统不制冷。当关闭空调后，发动机恢复正常。 ·故障检测：首先检测电路发面，在正常情况下，当压力开关b 、c端子之间电压为12v时，压缩机断开；压力开关b、c
