摘　　要：以管网年折算总费用最低为目标,选取管径、冷水流速、管道保温层厚度作为优化变量,将用户冷负荷需求和合理冷水流速范围作为约束条件,建立区域供冷系统管网优化目标函数,并采用正交优化方法进行优化计算。以株洲市神农城区域供冷管网为例进行计算,结果表明:管网设计参数对管网经济性的影响排序依次为:d(管径)、v(流速)、δ_t(保温层厚度),且三者都是不可忽视的主要因素;株洲市神农城区域供冷系统管网优化设计参数组合为d_e=300 mm,v_e=1.06 m/s,δ_(te)=0.057 m,年折算总费用为282 729元;正交优化法可以作为区域供冷系统管网优化设计的工具,适合一般工程技术人员使用。With the minimum total cost of pipe network taken as the goal,the pipe diameter,the cold water flowrate and the thickness of the pipe insulation layer taken as the optimization variables,the user cooling load demandand the reasonable cold water flow velocity range taken as the constraint conditions,an effort has been made toestablish the objective function of the pipe network optimization of the district cooling system,with the orthogonaloptimization method adopted to optimize the calculation.The results show that:arranged in a descending order,theinfluence of design parameterson the economical efficiencyof the pipe network will be:d(pipe diameter),v(velocity),δt(thermal insulation layer thickness),with all the three factors being fundamentally indispensable;the optimal designparameters of the district cooling system in Zhuzhou Shennong Urban District will be:de=300mm,ve=1.06m/s,δte=0.057m,with its annual total cost being282729yuan;the orthogonal optimization method,which can be usedas an optimization tool for the optimal design of pipe network in the district cooling system,proves to be useful andhelpful for the general engineers and technicians.
