随着空调蓄冷技术的不断发展，在一些分布式能源中心项目中，空调水蓄冷作为空调蓄冷的一种新方式，已逐渐展现出其在节能效果、经济效益和社会效益中的强大生命力和广阔市场。主要探讨了如何避免在自然分层水蓄冷系统的运行过程中，由于运行方式等问题造成水蓄冷罐内斜温层过大，从而导致能耗的浪费以及蓄冷系统利用率下降等一些问题。阐述了通过改进运行控制方式，使斜温层稳定在合理范围内，以确保整个水蓄冷系统安全、高效地运行。

With the continuous development of air conditioning cold storage technology, in some distributed energy center projects, air condition chilled water storage as a new way of air condition cold storage, it has gradually shown strong vitality and broad market because its energy saving effect and economic & social benefit. But some problem of operation mode caused the thermocline in water storage tank was too large, which led to some phenomenon like energywasting and system utilization rate decline. This paper mainly discussed that how to avoid this problem happened in process of naturalstratification storage system operation, and elaborated that how to ensure the operation of chilled water storage system was security and efficient by improving the operation control mode.
