 摘要
 空调器具有优良的空气调节功能，可以创造舒适的环境，从空调器的发展上看，
它经历了传统定速到现代调速的转变。传统空调器是定频定速空调器，压缩机的
转速不可调节，因此被控环境温度是波动的，舒适性差。由于电子技术、微电脑
技术、变频技术和控制理论的发展，使空调器的各方面性能大大提高，变频空调
取代了传统定频定速空调器，它优异的变频特性，可以快速制冷、制热，同时也
具有高效节能、噪音低、舒适度等特点。
 通过分析空调器的工作原理可知:制冷和制热都是利用压缩机将低压低温蒸汽
压缩为高压变温蒸汽实现的。将变频压缩机取代传统定频定速压缩机，对其进行
变频调速，可以提高空调器的性能。

CONTRLLER Abstract
 The air conditioner has preferable ability of regulating air so that it can create
comfortable environment. Its development has a great change from tradition
invariable speed to modern timing. Traditional air conditioner’s which the speed of
compressor is not regulatable, so the controlled temperature will fluctuate. With the
development of electronic technology, Micro-computer technology, variable
frequency technology as well as control theory, air conditioner’s capability get
improved in many aspects .Nowadays, the air conditioner which has advantages of
saving energy ,low noise, more comfortable,has good feature of variable frequency
and now it has replaced traditional air conditioner.
 We can know that the regulating of the temperature is realized by changing the air
from low temperature low pressure to high temperature high pressure via compressor.
by analyzing theory of air conditioner. While the variable frequency air conditioners
whose speed can be regulated replace the traditional one and improve the feature of
the air conditioner greatly.
 The fuzzy control technology is applied in air conditioner. The input comes from the
difference and the ratio of the difference of the temperature variety indoors,The output,
namely, the power frequency outside is deduced from input via using fuzzy control
theory. Namely the outdoors side the power supply frequency of the compressor, then
the controlling signal spreads to the outdoors through out-indoor serial
communication ,so it can adjust to speed of the compressor. This paper analyses the
basic structure, the principle, and the way of design of the fuzzy controller. According
to the basic and practical running experience of setting up fuzzy control rule, So that
can deduce a reasonable rule of fuzzy control, we can get preferable result o f the
temperature the fuzzy control. The hardware about this paper is 80C552 of Philips
single-chip computer, which has predominant control capability.
