冰球式蓄冷系统运行能耗的分析

摘要

本文建立了冰球式蓄冷系统计算模型，并用实验数据验证了模型的正确性，通过计算分析了不同冰球尺寸和载冷剂流量下的整个系统的蓄冷能耗变化规律，并综合考虑蓄冷时间、泵功率和制冷机 COP等因素，以最低能耗为目标，对冰球尺寸和载冷剂流量最佳值的选取进行分析%　　An encapsulated ice storage system model is established in this paper. The numerical results calculated by the model are validated by the experiments. The model is used to investigate the effects of the capsule size and the flow rate on the consumed energy of system and determine the optimal values in consideration of charging duration, power of pump and chiller COP.
