摘  要

 随着环境与发展成为人们普遍关注的问题，节能改造已成为工业企业共同的课题。冷却水系统如同单晶工艺生产的生命线，对于正常的生产和维护设备的安全起着至关重要的作用，但也是系统能耗的主要部分。在工艺冷却水系统设计过程中，采取节能措施，开发节能设计，降低水系统的电能消耗，不仅有助于控制生产线的电能消耗来减少企业生产成本，而且对于节能减排有积极的意义。
 本文对工艺冷却水控制系统和江森的智能楼宇管理系统——METASYS系统作了概述，并对工艺冷却水节能改造工程设计方案进行了分析和详细介绍。首先确定系统的控制点、设备的选型，然后运用GX9100软件来进行上位机编程，最后对控制方案进行实施。通过现场调试的结果表明，此次方案采用江森自控的METASYS系统，拥有其独特的优越性，取得了比较好节能效果。

Abstract
 
 Nowadays, as people are paying more and more attention on environment protection and development, Energy saving modification has already become the common issue for the enterprises. Just as the lifeline of crystal production technology, cooling water system plays a very vital role in normal production and the safety of equipment maintenance, but it''s also the main part of the system for energy consumption. In the technology cooling water system design process, to take energy conservation measures and develop energy-saving design, to reduce the power consumption of the water system will not only help control the production line to reduce power consumption production costs, but also has a positive meaning for energy-saving and emission-decreasing.
 The thesis summarized cooling water control system and Johnson''s Intelligent Building Management System——METASYS system, and introduced the design of cooling water energy-saving projects in detail. First, analyzed the system''s control points, determined equipment selection, then used GX9100 software to do upper computer programming, Finally finished the control scheme. Through completing site debugging, the results show that Johnson Controls''s METASYS has its unique advantages, the proposal plays better in energy saving.
