1、毕业设计(论文) 题目:汽车空调制冷不良故障诊断与检修摘要随着汽车工业的发展和人们生活水平的提高,人们对汽车的舒适性、安全性的要求日益提高,汽车空调已由原来只给高档轿车配置,发展为被各型客车、货车、工程车和特殊用途车辆广泛采用的标准配置汽车空调的普及、发展和不断创新已成为汽车行业的一大亮点。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。空调的控制方法也经历了由简单到复杂,再由复杂到简单的过程。作为汽车空调系统的电路控制方面也再不段的更新改进。本文
2、从实际出发,全面、系统地阐述了空调系统的基本结构、工作原理、诊断维修方法。列举了大量的维修实例,详细地讲解了空调系统故障的现象、原因和排除方法。最后以故障检修深入探讨。关键词:汽车空调发展检修第22页ABSTRACTAlongwithautomobileindustrydevelopmentandpeoplelivingstandardenhancement,thepeopletotheautomobilecomfortableness,thesecurerequestenhancedaybyday,theautomobileaircon
