摘要
本文提出了一个计算任意结构换热网络灵敏度系数及灵敏度的通用数学模型，并给出了求解数学模型的方法。编制了计算机程序并用实例进行了考核计算。换热网络的灵敏度及灵敏度系数对分析干扰变量对被控变量和目标函数的影响是非常重要的。根据换热网络的灵敏度系数，可对换热网络的操作性能进行分析，对换热网络提出最佳改进方案。
A mathematical model and computer program are developed in this paper,for calculation of the sensitivities and sensitivity coefficients of the heat exchanger systems with various configurations. The mathematical formulations used in the calculations, based on the basic input information about the structure of the heat exchanger system, and the necessary data used in the theoretical analysis of the operability of the heat exchanger system can be provided by the program.
