一、前言 能量系统的综合是近二十年来日益活跃的研究领域。使用启发式规则与热力学目标技术已在几种类型的综合问题(主要是换热网络)中取得显著成就,但它们并不能系统地提供普遍性的方法,一般情况下也不能保证最优。能量系统研究的另一学科分支是热经济学,目前大体可分为热经济学分析、热经济学优化与热经济学综合。其中有关热经济 I. INTRODUCTION The synthesis of energy systems is an increasingly active research field in the past 20 years. The use of heuristic rules and thermodynamic target technologies has yielded significant achievements in several types of synthesis problems, primarily heat exchange networks, but they do not provide a systematic way to universalize nor are they generally guaranteed to be optimal. Another branch of energy system research is thermal economics, at present can be divided into thermal economics analysis, thermal economics optimization and thermal economics synthesis. Which is related to the thermal economy
