摘　　要：我国电力供应中出现的峰谷负荷差大的现象促进了蓄冷空调系统的发展。在一些大型的能源中心建设项目中,空调水蓄冷展现了其在节能效益、经济效益以及社会效益上的巨大优势。水蓄冷罐是整个蓄冷系统的关键设备,其效率的高低直接影响到整个系统的运行经济性。通过测试某能源中心水蓄冷项目实际案例,介绍减小斜温层厚度的若干改进措施,可为水蓄冷系统的优化运行提供参考。The cold storage air conditioning system is developed in China, because of the phenomenonof large peak - valley load difference in power supply. In some large - scale energy center constructionprojects, air - conditioning chilled water storage shows its huge advantages in energy - saving, economicand social benefits. Storage tank is the key equipment of the entire storage system, its efficiency directlyaffects cost of the entire system. By testing the actual case of a water storage project in an energy center,some improvement measures to reduce the thickness of the thermocline are introduced, which can providereference for the optimal operation of the water storage system.
