摘要目前，室内的空气污染日益严重，很多地方的室内及室外空气质量经常处于非良好的状态，一些地方甚至达到重度污染，严重影响了人们的身体健康。有研究显示，人们一生中平均80%以上的时间都在室内度过，所以净化室内空气、提高室内空气质量尤为重要。目前分散式空调机组如挂壁式、立柜式等虽然有空气过滤作用，但是均为粗效过滤，不能满足改善目前空气状况的需要。这篇论文通过研究空气环境污染的现状，学习净化空调系统基本原理和常用的空气净化方式，设计了一款净化空调，并利用ProE软件建立了净化空调的基本模型。本设计属于一种实用新型产品的设计，偏向于系统结构设计，所以计算部分较为简略。为达到本设计的目标，笔者在几种系统结构形式中分析比较，选择了一种比较合理的系统结构。大胆地将静电除尘器应用于分散式空调机组，取得了较为良好的效果。86936

Abstract The indoor air pollution has become more serious so far。 And the indoor and outdoor air pollution index (API) is not that optimistic in many places, some of which are even heavily polluted and this is severely detrimental to the public’s health。As is revealed in researches, people spend over 80% of their lives inside the houses。 Thus it is of great significance to purify indoor air and improve the indoor air quality (IAQ)。At present, the wall-mounted and the floor-standing decentralized air-conditioning unit, though both function in filtering the air, are with coarse filters, which cannot satisfy the need of ameliorating the present air situation。This thesis, therefore, is to design an clean air-conditioning and has established a base model of it after investigating the present condition of air pollution and studying the basic principle of air-cleaner systems and those frequently-used air cleaning approaches。This design is a new kind of functional product, and this paper mainly focuses on the systematic structure design of it and simplifies the calculation part。 In order to achieve the goal of this design, we have selected a relatively reasonable one based on the analytic comparison of several modes of systematic structures。 Favorable results have been acquired with the application of electrostatic precipitator (ESP) in the decentralized air-conditioning unit。
Keywords: clean air-conditioning; air filter; electrostatic precipitator (ESP); air purification
