摘要

自本世纪20年代空调诞生以来，伴随汽车空调的普及与发展，汽车空调的发展大体经历了五个阶段：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。我国汽车空调的安装随着汽车空调的发展已到达100%的普及性，空调已经成为现在汽车的一种基本配备。本文论述了空调系统的分类，凌志LS400空调控制系统的结构和工作原理，并对空调系统的重要组成部分（供暖通风系统、制冷系统、自动温度控制系统）进行详细的介绍，以及空调系统出现的故障，并对故障进行分析和探究，找到引发故障的因素，通过对其原理组成，工作作用的分析，对故障进行排除。探究对空调控制系统的维护和保养，了解到对汽车空调系统维护保养的方法，对空调系统的各个重要组成部分进行一个系统的分析，从而了解空调控制系统的工作原理。

关键词：空调控制系统结构、工作原理、故障排除、维护保养

Abstract

Since this century 20 time air conditioning was born, along with the development and popularization of automobile air conditioner, the development of automotive air conditioning has generally experienced five stages: single stage, single stage, warm air heating and integration phase, automatic control, computer control stage. China's automotive air conditioning installation with the development of automotive air conditioning has reached the 100% universal, air conditioning has become now a vehicle equipped with the basic. This paper discusses the classification of air conditioning system, the structure and working principle of Toyota Lexus 400 air-conditioning control system, and an important part of the air conditioning system (heating and ventilation system, cooling system, automatic temperature control system) are introduced in detail, and the air conditioning system fault, and the fault analysis and inquiry, to find the factors causing the fault, the composition of the principle, analysis function, elimination of faults. Research on air conditioning control system maintenance and maintenance, to understand method of automobile air conditioning system maintenance, each important part of air conditioning system is a systematic analysis, to understand the working principle of air conditioning control system.

Keywords: air conditioning control system structure, working principle, troubleshooting,

maintenance
