摘　　要：为解决不同蓄冷率对冷水机组、蓄冰装置、土建投资和年运行电费产生的成本增量或减量影响不同,提出了全寿命周期成本分析方法。通过实际项目冷负荷计算、系统配置及全寿命周期成本计算,对比分析得到了不同蓄冷率与系统全寿命周期成本的变化关系曲线。结果表明:冰蓄冷系统全寿命周期成本受系统投资、运行费用、建设用地综合开发费用等多方面影响,需根据项目实际情况,开展全寿命周期成本分析对比,方可确认实际工程的最佳蓄冷率;案例项目冰蓄冷系统全寿命周期最佳蓄冷率为26.2%,供冷站全寿命周期成本约为59708万元。In order to solve the varying impact of different cold storage rates on the cost increase or decrease of chiller units,ice storage devices,civil construction investment and annual operation electricity costs,a whole life cycle cost analysis method is proposed.Through the cooling load calculation,system configuration and whole life cycle cost calculation of an actual project,the relationship curve between different cold storage rates and whole life cycle cost is obtained by comparative analysis.The results show that the whole life cycle cost of ice storage system is affected by system investment,operation cost,comprehensive construction land development cost,etc.It is necessary to analyse and compare the whole life cycle cost according to the actual situation of the project in order to confirm the optimal cold storage rate of the actual project.The optimal cold storage rate for the whole life cycle of the ice storage system of the case project is 26.2%,and the whole life cycle cost of the cold station is approximately 597.08 million yuan.
