A320飞机空调系统工作原理与使用维护分析

摘要

飞机空调系统是飞机中一个很重要的系统,它的基本任务是使飞机的座舱和设备舱在各种飞行条件下具有良好的环境参数,与飞机在飞行过程中人员的正常工作和生活以及设备的正常工作有着直接关系。空调系统遍布飞机驾驶舱、客舱、货舱和电子设备舱等,管路、部件、系统结构繁多,在使用过程中,很容易出现各种问题。

本篇论文首先通过对飞机空调系统进行了一个概述性的描述,说明了人体会环境参数的要求。然后以空客320飞机空调系统为例,对A320飞机空调系统以及部件进行了详细的介绍。最后对A320飞机空调系统常见的故障进行了分析并且提出了排故措施。在提高对飞机空调系统的认知度的同时,也为以后的工作提供了参考资料,减少了不必要的资源浪费。

A320 飞机空调系统工作原理与维护分析

Airbus A320 Air Condition System

Working Principle and Maintenance

Abstract:

The air condition system is a very important system in an aircraft. The main function of this system is to maintain a suitable parameter during flight in the pressure zones. It directly affects human’s and equipment’s working. Air condition system distributes in many components like cockpit, cabin, cargo and electronic compartment. It has a high possibility to get malfunction because of its complicated ducts, components and structure.

Firstly, a summary of air condition system is introduced. It provides human’s requirement of environment parameters. Secondly, airbus 320 air condition system and its components are introduced in detail. At last, several kinds of common failures are analysed and the relative troubleshooting procedure is advised. It can help people understand the aircraft air condition system, provide reference media and save the resources at the same time.

Key Words: air condition, working principle, failure analysis.
