摘要
TFT-LCD工厂具有投资高、建筑体量大、能源消耗量大的特点。为了在工厂设计、建设、运营阶段有的放矢地做好节能降耗工作，针对重点耗能工序、耗能设备以及影响能耗的关键因素，采取科学、合理、可行的节能措施和节能工程，从而达到更好的节能效果。本文对TFT-LCD工厂能源消耗种类、能源消费结构及能源分布特点、主要能源加工转换过程中的能量平衡、能效指标等进行了研究分析。总结我院多年来完成的同类项目经验数据，通过层次分析法、能量平衡分析方法、标准对照方法等对主要用能体系及用能特点进行深入剖析。分析结果表明，电力是TFT-LCD项目消耗量最大的能源，约占全厂综合能耗的75%以上，其中工艺生产设备电力消耗约占全厂用电的45%~50%，阵列为最主要的工艺耗能工序，厂务系统中冷水机组等动力设备是主要耗能设备；氮气是消耗量最大的耗能工质，约占全厂综合能耗的20%。能源消费结构及用能特点基本符合此类工厂实际运行特点，对TFT-LCD面板项目节能具有较高的指导价值。
Abstract
TFT-LCD factory has the features of large investment
FAB size and energy consumption. To save energy and reduce consumption more effectively during FAB design
construction and operation
scientific
reasonable and feasible energy-saving measures and projects were taken to the key energy-consuming process
energy-consuming equipment as well as the critical factors affecting energy consumption. In this paper
the type and structure of energy consumption
distribution characteristics
energy balance
and energy efficiency index in TFT-LCD factory were studied. Analytic hierarchy process
energy balance analysis and standard comparison method were used to deeply analyze the main energy system and characteristics by summarizing the empirical data of similar projects designed by CEEDI these years. The analysis shows that electricity is the largest consumption of energy
accounting for about 75% of the comprehensive energy consumption of the whole factory. The power consumption of production equipment accounted for about 45% to 50% of all electrical
and array is the main energy consuming process
while the chiller system is the main energy consuming facility. In addition
nitrogen is the largest consumption medium
accounting for about 20% of the comprehensive energy consumption of the whole factory. The energy consumption structure and characteristics in this paper is consistent with actual operation characteristics of such factories
and it could be of high directive value to energy-saving for TFT-LCD projects.
