Abstract: In this paper a method based on enthalpy intervals of composite curves is presented for area targeting of Heat Exchanger Network in the presence of stream split constraints. The results show that in the case of slightly different fihn heat transfer coefficients the network structure without stream split constraints can reach a good area target, but in the case of significantly different coefficients the network structure with stream split constraints can achieve a better area target by optimally arranging match sequences.

摘要： 基于组合线能量分区的概念,提出分流约束条件下换热网络的面积目标计算方法.结果表明,当传热膜系数差别小时,分流结构具有较小的面积目标;而当传热膜系数差别大时,则分流受约束的网络结构也可具有良好的面积目标.
