汽车空调系统的结构、原理与检修(论文6000字)
摘 要
   汽车空调系统可以对车厢实现制冷、加热、换气的装置。目前，空调装置已经成为衡量汽车功能、汽车配置以及汽车价格的重要标志之一。良好的空调系统可以有效降低驾驶员的疲劳感，提供良好的乘车环境，间接提升行车安全。
    伴随着社会经济的发展，汽车行业伴随着当前的社会背景，也得到了前所未有的发展机遇。人们的生活水平提高，汽车的普及程度也逐年上升。过去，人们主要追求汽车的可靠性及安全性。发展至现在，人们逐渐重视对汽车驾驶的舒适性要求。因此，在现代轿车中，空调系统是一项必不可少的基本配备。在未来，人们对于空调系统的优化逐渐成为发展的潮流。
最近几年，环保问题逐渐成为人们日益关注的焦点，与此同时也是影响汽车发展的一项重要因素。人们开始研发及追求新型能源动力车，从而取代传统能源汽车，以达到保护环境的目的。所以，这就为汽车的空调系统带来了新的挑战。
    对此，笔者基于空调系统的结构、工作原理、检测维修这三个角度出发，进行系统全面的阐述。
关键词：空调系统，结构，工作原理，检测维修

abstract
The automobile air conditioning system can be used to refrigerate, heat and air the car. At present, the air conditioning system has become one of the important signs to measure the function of the car, the configuration of the car and the price of the car. A good air conditioning system can effectively reduce the fatigue of the driver, provide a good vehicle environment, and indirectly improve the safety of driving.
Along with the social and economic development, the automobile industry is accompanied by the current social background, and has also received unprecedented opportunities for development. People's living standards have improved, and the popularity of cars has also increased year by year. In the past, people were mainly pursuing the reliability and safety of the car. At present, people gradually pay attention to the comfort requirements for driving. Therefore, in modern cars, the air conditioning system is a necessary basic equipment. In the future, the optimization of air conditioning system has gradually become the trend of development.
In recent years, environmental protection has gradually become the focus of attention, and at the same time, it is also an important factor affecting the development of automobiles. People have begun to develop and pursue new energy vehicles, thus replacing traditional energy vehicles in order to protect the environment. So, this has brought new challenges for the automotive air conditioning system.
In this regard, the author, based on the three angles of the structure, working principle and inspection and maintenance of the air conditioning system, makes a systematic and comprehensive exposition.
Key words: air conditioning system, structure, working principle, inspection and maintenance
