摘要
考虑回油模型、换热模型、压降校核模型及制冷剂的热物性参数,建立了竖直单U形管换热器的计算机优化程序。以某工程为例,预测了优化设计参数,并分析比较了优化前后系统的COP、运行费用及初投资。
Considering the oil return model,heat transfer model,pressure drop checking model and refrigerant thermo-physical parameters,establishes an optimal computer program.With a project example,predicts the optimum values of design parameters,and analyses and compares the system COP,operational and initial costs between before and after the optimal design.
