换热网络的动态柔性及其优化

在探讨换热网络可控性和抗干扰能力两方面性能的基础上,提出了换热网络动态柔性的概念,并分析了该性能参数对实际换热网络运行的影响。在此基础上提出了考虑换热网络可控性和运行稳定性的优化设计方法。结果表明,将动态柔性参数引入到换热网络优化设计中,不仅能够兼顾稳态和动态两方面性能,还可得到更适合实际需要的换热网络结构。

Dynamic flexibility of heat exchanger networks and optimization

A concept of heat exchange network's dynamic flexibility has been proposed based on the discussion of the heat exchange network's controllability and anti-jamming capability,and also analyzed the influence on the actual heat exchange network.Based on this works,an optimization design method has been put forward considering the controllability and operation stability of the heat exchange network.The result shows that,more suitable structure for the actual demand of the heat exchange network can be acquired by using the method which was introduced the dynamic flexible parameter into the heat exchange network optimization design;it can also keep the steady state and dynamic performance.
