凯美瑞轿车空调故障分析和维修工艺

摘要

汽车空调系统是实现对车厢内空气进行制冷、加热、换气和空气净化的装置。它可以为乘车人员提供舒适的乘车环境，降低驾驶员的疲劳强度，提高行车安全。空调装置已成为衡量汽车功能是否齐全的标志之一。作为汽车业维修人员,我们应该知道作为汽车组成的一部分:汽车空调的组成和功用,并应对汽车空调系统常见故障现象、故障部位、故障的检测、诊断和排除有一定的认识,明确其检测和诊断的基本思路。本设计以凯美瑞轿车为参照讲述了汽车空调的组成与功用，制冷剂和压缩机油，制冷原理，空调制冷剂和压缩机油的检查与加注，以及润滑系常见故障诊断与排除，以及凯美瑞空调系统的维修案例。随着汽车科技的发展，汽车空调的结构也随之越来越复杂。我们只有掌握更多的知识和实践经验，才能更好地运用检测仪器快速准确地查找汽车空调的故障原因，并把故障排除。

Abstract

Vehicle air conditioning system is a device for cooling, heating, ventilating and purifying air in the compartment. It can provide passengers with a comfortable ride environment, reduce the driver’s fatigue strength, improve traffic safety. Air conditioning unit has become a measure of whether the car is fully functional signs.

As the auto industry maintenance personnel, we should know that part of the composition as a car: the composition and function of the automobile air conditioning, and deal with the automobile air conditioning system common faults, fault location, fault detection, diagnosis and exclusion has a certain understanding, clear the detection and diagnosis of the basic ideas. This design to Camry sedan for reference about the composition and function of the automobile air conditioner, refrigerant and compressor oil, refrigeration principle, air-conditioning refrigerant and compression check and filling of lubricating oil and lubricating system common fault diagnosis and elimination, and Camry air-conditioning system maintenance case cases. With the development of automobile technology, the structure of the automobile air conditioning is more and more complicated. We only have more knowledge and practical experience, to better use of the detection instrument to quickly and accurately find the fault of the car air conditioning, and troubleshooting.

Keywords: Automotive air conditioning structure fault diagnosis and maintenance of matters needing attention
