大温差水蓄冷技术应用及经济性分析

Application and economic analysis of large temperature difference water storage technology

水蓄冷技术作为移峰填谷间接的提升整个电网的运行效率,在不同领域予以推广,大温差(温差10℃以上)水蓄冷系统具有蓄冷水罐占地少、系统运行效率高等优势,但由于使用过程中的条件限制在实际工程中应用不多。通过对应用中的蓄冷温度控制及放冷策略进行分析,提供解决方法,保证了该技术的成功应用并取得较好的经济效果,对后续蓄冷项目的应用提供参考。

Water storage technology,as a peak-shifting and grain-filling technology,indirectly increases the operating efficiency of the entire power grid,and is promoted as a nationally-promoted energy-saving technology in various fields.The large temperature difference(temperature difference above 10℃)water storage system has the advantages of less space for storage of cold storage tanks,higher system operation efficiency,etc.However,due to the limited practical conditions in the practical use of the process,there are few applications.Analyze and provide solutions for the cold storage temperature control and cooling strategy in the application,and successfully apply it in the project and obtain a good economic effect.Provide reference for the application of the following cold storage project
