摘 要
随着近年来经济的迅速增长，中国的能源形势日益严峻，能源的供给已经成
为了经济增长的瓶颈，各行各业越来越认识到节能的重大意义。节约能源，建设
节能型社会已经成为我国经济社会发展的必然选择。当前我国建筑能耗约占社会
总能耗的 30%，其中中央空调能耗占整个建筑物运行能耗的 60%左右。中央空调
系统节能控制在节能领域具有非常重要的地位。
本文基于变频器设计并实现了一套能有效实现中央空调节能的控制系统。本
文简述了模块式中央空调控制系统的工作原理， 详细介绍了该节能控制系统的
原理图、电路图、和该模块式空调控制系统的硬件系统配置，并简述了其软件系
统的设计。该控制系统是在对现有中央空调工作原理及现有的各种中央空调节能
控制系统进行详细研究和分析基础上，设计并实现的， 其性能可靠， 节电效果
显著。
本文还为某一图书馆设计了此中央空调控制系统，并讨论了中央空调节能原
理：环境温度通过温控器反馈给变频器，从而通过变频器频率变化来调节风机、
水泵电动机转速，随电动机转速变化使风机、水泵的风量、流量随之变化，从而
来达到节能的目的。

Abstract
Abstract
Along with the rapid economic growth in recent years, China's energy situation
becomes increasingly serious, energy supply has become the bottleneck of the
economic growth, various industries increasingly recognized the significance of
energy conservation. To save energy, building energy-saving society has become
China's economic and social development of the inevitable choice. The current our
country building energy consumption accounts for about 30% of the total energy
consumption society, including central air conditioning of the total energy
consumption of building the operating energy consumption around 60%. The central
air conditioning system in energy saving energy control is a very important position.
Based on the inverter is designed and realized a set of effective energy saving
realize central air conditioning control system. This paper briefly describes the
module type central air conditioning control system was introduced, the principle of
energy control system principle diagram, diagram, and this module type
air-conditioner system configuration of the control system, and introduces the
hardware design of the software system. This control system is on existing central air
conditioning working principle and all kinds
