【正文】 摘 要 II 摘 要 隨著汽車工業(yè)的迅猛發(fā)展和人民生活水平的日益提高，汽車開始走進千家萬戶。人們在一貫追求汽車的安全性、可靠性的同時，如今也更加注重對 舒適性的要求。汽車空調(diào)的功能是通過認為的方式創(chuàng)造一個對人體適宜環(huán)境。 本文針對于 汽車 空調(diào)制冷系統(tǒng)使用中存在的問題，分析了制冷系統(tǒng)的組成部件、工作原理、常見故障 以及后期的保養(yǎng)與維護等內(nèi)容 。并 歸納關(guān)于 汽車 空調(diào)制冷系統(tǒng)常見故障診斷 方法 與排除流程。s living standard, car entered families. People always in pursuit of automobile safety, reliability, at the same time, also pay more attention to the requirements of fort now. Therefore, air conditioning system as a basic equipped with modern cars, became inevitable. The function of auto air conditioner is through the way of thought to create a suitable environment to the human body. Automotive air conditioning refrigerating system, heating system, ventilation system, the operation control system and air purifying system. This article on automotive air conditioning refrigerating system, problems existing in the use of the ponents of the refrigeration system are analyzed, the working principle, mon failure and later maintenance and maintenance, etc. Fault inspection and related professional equipment, analysis the cause of the problem, based on the practical maintenance. And about automotive air conditioning refrigerating system mon fault diagnosis methods and processes. Keywords:Automotive airconditioning refrigeration system troubleshooting maintenance 目 錄 IV 目 錄 摘 要 .............................................................................................................................II ABSTRACT .................................................................................................................
