摘　　要：输配系统的运行能耗是空调冷水系统能耗的重要部分。总结分析了典型地铁车站冷水系统各部件的循环阻力情况,给出水泵选型一致的一次泵输冷比的简化计算式及水泵扬程限值图,供设计参考。由于地铁车站冷水系统输冷比普遍接近节能规范的限值,为此须严格控制最不利环路水力损失。建议水泵的设计扬程不宜大于40 m,冷水系统最不利环路比摩阻不宜大于200 Pa/m。The energy consumption of transportation system is an important part of the energy consumption of air conditioning chilled water system.The circulating resistance of each component of the cooling water system in typical metro station is summarized and analyzed,giving a simplified formula for calculating the electricity consumption to transferred cooling quantity ratio of primary pump system with the same type of pumps and the limit for the head of pumps,providing reference for design.Electricity consumption to transferred cooling quantity ratio of the chilled water system in metro station is generally close to the limit value,thus the most disadvantageous hydraulic loss of the loop should be strictly controlled.The design head of pumps should not be greater than 40 m.The resistance should not be greater than 200 Pa/m.
