摘要:随着科技的不断发展,人们为了创造良好的空气品质,提供舒适的生活环境,令自身生活水平不断提高,空调系统被广泛的使用。但在当前能源紧张的时代,节能减排受到了日益的重视,研究现代建筑的节能具有重要意义。31035
空调系统是智能建筑中楼控系统的主要组成部分,但与此同时其又是耗能大户。因此,节能成为人们普遍关注的问题。作为智能建筑的节能措施之一的变风量空调系统,其属于全空气系统,它具有全空气系统的一些优点;能够节约风机运行能耗和减少风机装机容量;除此之外,该系统的灵活性较好,易于改、扩建,尤其适用于格局多变的建筑。因此逐渐成为楼宇自动化空调系统设计的主要趋势。                 
本文首先介绍了变风量空调系统和智能楼宇管理系统,然后对变风量空调系统的控制构成和控制方法作了分析和详细的说明。
随后论述了在充分利用智能楼宇设备资源及其智能化特点的基础上 ,对智能楼宇变风量空调系统进行节能控制 ,使其达到最佳的运行效果和节能效果的一些方法和思路。
 最后以典型变风量空调系统为控制模型,以智能楼宇管理系统以及直接数字控制器等相关产品为研究平台,在实际工程项目中设计并应用了变风量空调系统。通过分析确定了工程项目中变风量空调系统的监控点数、设备的选型,并运用组态软件设计系统,证明本文所设计的研究方案在达到良好控制效果的同时也获得了满意的节能效果。 源自[六^维$论'文}网(加7位QQ3249`114 www.lwfree.cn

Variable air volume air conditioning system control system research
Abstract:With the continuous development of science and technology, people in order to create the good air quality, provides the comfortable life environment, make their own living standards continue to improve, air conditioning system has been widely used. But in the current era of energy, energy conservation and emissions reduction has been increasingly attention and research of modern architecture energy saving is of great significance.
 Air conditioning system is the main part of the building control system in intelligent buildings, but at the same time it is a large energy consumption. Therefore, energy saving become issues of common concern to people. As one of the intelligent building energy saving measures of variable air volume air conditioning system, it belongs to all air system, it has some of the advantages of all air system; Can save energy consumption of the fan operation and reduce fan installed capacity; In addition, the system has good flexibility, easy to change and expansion, is particularly applicable to the chequered architecture. So gradually become the main trend of building automation air-conditioning system design.
This paper first introduces the variable air volume air conditioning system and intelligent building management system, and control of the variable air volume air conditioning system composition and control method were analyzed and detailed instructions.
Then discussed in make full use of the intelligent building intelligent equipment resources and its characteristics, on the basis of the intelligent building for energy saving control of vav systems, to the best operation effects and energy saving effect of some methods and ideas.
Finally in a typical variable air volume air conditioning system for the control model of intelligent building management system, and related products such as direct digital controller as the research platform, in the practical engineering project design and application of the variable air volume air conditioning system. Project was determined by the analysis of the variable air volume air conditioning system of monitoring points, equipment selection, and use configuration software design system, proved in this paper, the designed research plan in achieve good control effect and obtained the satisfactory result of energy saving. 变风量空调系统的控制系统研究:http://www.lwfree.cn/zidonghua/20181203/27052.html
