郑州科技学院专科毕业论文（设计）题目汽车空调制冷系统设计姓名专业汽车制造与装配班级08汽配系别机械工程系指导老师完成时间2010年12月15日汽车空调制冷系统设计摘要汽车空调制冷系统的发展是驾驶员及乘车在驾驶和乘车的时候能拥有一个比较舒适的驾驶和乘车环境。由于汽车空调比家用空调使用的环境更加恶劣，所以对汽车空调要求很高，另外汽车空调的安装比家用空调难度大要求高，所以需要设计出新的汽车空调制冷系统。本文针对汽车空调发展史、汽车制冷剂及汽车空调各主要部件的作用及工作原理做了讲解。还对汽车空调工作原理做了简单的说明。关键词汽车空调制冷系统组成原理AUTOMOTIVEAIRCONDITIONINGANDREFRIGERATIONSYSTEMDESIGNABSTRACTAutomotiveairconditioningandrefrigerationsystemisthedevelopmentofthedriverandrideindrivinganddrivingtimecanhaveamorecomfortablepostureanddrivingenvironment.Becauseautomotiveairconditioningthanhouseholdair-conditioneruseenvironmentmoresevere,soforautomotiveairconditioningisdemanding,additionallytheinstallationofairconditioningthanhouseholdair-conditionerdifficultrequirehigh,soweneedtodesignanewautomobileair-conditioningandrefrigerationsystem.Thispaperautomotiveairconditioninghistory,automobilerefrigerantsandautomotiveairconditioningofmajorpartsoffunctionandprincipleofworkofautomotiveairconditionerexplaining.Workprincipleofsimpleexplanation.KEYWORDSAutomotiveairconditioningTherefrigerationsystemCompositionprinciple目录中文摘要.....................................................................................................I英文摘要...................................................................................................II1汽车空调制冷系统的发展.................................................................12车空调制冷系统特点............................................................................13汽车空调制冷剂和润滑油....................................................................13.1制冷剂..............................................................................................13.2润滑油..............................................................................................24汽车空调制冷系统各主要部件.............................34.1压缩机..............................................34.1.1压缩机的合理选型和匹配....................................34.1.2确定合适的传动比..........................................54.2膨胀阀和膨胀节流管..................................74.2.1膨胀阀....................................................74.2.2膨胀节流管的结构和工作原理...............................104.3冷凝器.............................................................................................114.3.1汽车空调冷凝器的作用与布置...............................114.3.2冷凝器的结构.............................................114.4蒸发器.............................................................................................124.4.1作用和特点...............................................................................................124.4.2主要结构形式.............................................124.4.3蒸发器箱总成构造.........................................134.5储液干燥器.........................................144.6气液分离器（积累器）...............................154.7电磁离合器.........................................164.8电磁阀.............................................................................................174.9电磁旁通阀....................
