摘要

Combined with the practical testing method,proposes a simplified analysis model for ice cool storage system and applies an analytic method to its optimization procedure.Optimizes two practical cases of project A and B.Obtains that the optimal temperature difference between supply and return water is 2.7 ℃ in the project A and 4.5 ℃ in the project B.The whole process simulation results of the practical cases show that the optimal temperature difference is 0.2 ～ 0.3 ℃ higher than that of simulation results,which demonstrates the effectiveness of the analysis model.The proposed model is of significance in the parameter setting and planning process in ice cool storage systems.%结合实际测试方法,提出了一个简化的蓄冷系统分析模型,并给出了其优化过程的解析方法.对应用这一模型的项目A,B2个实际案例进行了优化,得到项目A的最优供回水温差为2.7℃,项目B的最优供回水温差为4.5℃.对实际案例进行了全过程模拟,结果显示,其优化的供回水温差比模型结果略高0.2～0.3℃,表明了这一模型结果的有效性,对冰蓄冷系统的参数设定与前期设计均具有借鉴意义.
