基于METASYS的空调自控系统设计 摘要 空调系统是智能建筑中楼控系统的主要组成部分，但也是系统能耗的主要部分。随着人们生活水平的不断提高，空调系统被广泛的使用，节能成为人们普遍关注的问题。由于变风量空调系统显著的节能特点，使其成为空调系统的主流。同时美国江森公司的METASYS智能楼宇管理系统，以其独特的优越性，使得空调节能得以更好的发挥。 本文首先对变风量（VAV）空调系统和江森的智能楼宇管理系统——METASYS系统作了概述，还对VAV系统的控制原理和方法进行了分析和详细说明。通过分析确定系统的监控点、设备的选型，运用组态软件设计METASYS系统的上位机人机界面，最后在MATLAB/Simulink环境下对表冷器和变风量末端的控制器进行了仿真。 关键词： 节能，VAV空调系统，METASYS系统 Design of Air Conditioning control system based on METASYS Abstract The air-conditioning system is the main constituent of the building controls system in the intelligent building, and is the main part of system energy consumption. Along with the enhancement of people living standard, the air-conditioning system were widespread used, energy saving became the universal matter of people concerned. Because of Variable Air Volume air-conditioning system’s remarkable characteristic of energy saving, it become the mainstream of air-conditioning system. Simultaneously the American company JOHNSON-METASYS intelligence building management system having its unique superiority, that makes the energy saving of air-conditioning system better. Firstly, this paper gives the outline of the Variable Air Volume (VAV) air-conditioning system and the JOHNSON—— METASYS intelligent building management system, also has analysis and specified the VAV system control principle and the method. By the analysis, determining system monitoring point, choosing the equipment, has designed the METASYS software configuration on workstation was successfully. Finally, the simulation to the cooling coil and VAV terminal controller were carried on in MATLAB/Simulink environment.
