地铁冰浆集中供冷系统二次管网保温层厚度及管道内径的优化
Optimization of inner diameter and insulating layer thickness of secondary pump system for central cooling system of underground railway stations with ice slurry
摘要：
以二次管网供冷管路的年费用为目标函数，建立了优化模型。分析了电价、输送半径、车站负荷、区间隧道温度、隧道风速、冰浆含冰率、保温层价格和导热系数及系统的COP对二次管网年费用的影响。

Abstract：
Taking annual cost of secondary pump system as objective function, develops an optimal model. Analyses the impact of power price, transportation radius, cooling load of underground railway stations, temperature and air velocity in section tunnels, ice packing factor, price and thermal conductivity of insulation materials, and system COP on the annual cost.
