摘　　要：通过对过冷式小型冰蓄冷系统火用分析模型的建立,采用火用分析的方法,揭示了小型过冷式冰蓄冷系统的能量转换的薄弱环节以及过冷度对各部件火用损失系数和系统火用效率的影响。分析了减少火用损失的途径,节约能源。并为系统的改进和优化提供有力的理论参考。The paper sets up the model for exergy analysis on overcooled refrigeration with ice storage system. According to the method of exergy analysis, the weak part of energy conversion in overcooled refrigeration with ice storage system is revealed and it appears the regularity of exergy loss coefficient and exergy efficiency changing with super - cooling degree. It also points out the method of decreasing of exergy loss and energy saving. In a word, the paper provides the theory reference for improvement and optimization of the system.
