基于虚拟温焓图法的换热网络结构优化

Structure Optimization of Heat exchanger Network Based on Pseuco-temperature

在虚拟温焓图法的基础上,提出断开热负荷回路的规则,建立数学模型证明提出的规则,应用提出的规则对换热网络进行结构优化。通过换热网络结构优化的方法能减少换热器的个数和总费用,最后该方法应用于实例中证明方法的有效性。

Based on heat exchanger network synthesis,specific rules are proposed according to build mathematical models.Structure optimization can be done to disconnect loop of heat exchanger network by using of proposed rules. Structure optimization was performed to reduce number of heat exchangers and annual total cost. At last an example is used to show the application and effectiveness of proposed method.
