在合成最优换热网络时,存在着调优迭代计算时间长、过程复杂等问题,本文围绕这一课题,以智能图表法为理论基础,结合C++的编程思想,以Microsoft Visual Studio 2008为开发平台,利用换热网络优化节能技术编写了换热网络合成软件。该软件具有以下功能:根据冷、热物流相关数据,计算换热网络夹点、生成温—焓组合曲线图并标出夹点温度,计算出最大热回收量和最小能量体用量,根据物流匹配换热规则和智能图表对相关冷热物流进行匹配,计算出冷热物流热交换的热负荷、换热面积、操作费用等,自动合成最优换热网络并将计算结果存于文本文件result.txt中。经实例核算后与其它文献数据对比结果可靠合理,表明该程序应用方便,计算速度快,可大大简化合成换热网络的计算过程。
When synthesizing the optimal heat exchange network, there are many problems such as long time of tuning iteration, complicated process, and so on. Based on this topic, based on the theory of intelligent charting, combined with the programming ideas of C ++ and Microsoft Visual Studio 2008 Platform, the use of heat exchanger network optimization of energy-saving technology to compile the heat exchanger network synthesis software. The software has the following functions: Calculate the pinch points of the heat exchange network according to the relevant data of cold and hot logistics, generate the temperature-enthalpy combination curve and mark the pinch temperature, calculate the maximum heat recovery and the minimum energy consumption, according to the logistics matching Heat transfer rules and smart charts to match the relevant hot and cold logistics to calculate the thermal load of hot and cold logistics heat exchange, heat transfer area, operating costs, etc., automatically synthesized optimal heat exchange network and the results stored in a text file result. txt. The results of the comparison with other literature data after the example calculation are reliable and reasonable, which shows that the program is easy to use and fast in calculation, which can greatly simplify the calculation process of the synthetic heat exchange network.
