摘要
区域供冷系统在节能、运行管理及经济性方面具有明显的优势,介绍了广东省某区域集中供冷系统的应用研究,分析了区域设计日负荷及全年逐时负荷。从可用能源入手,根据具体条件,分析确定了适宜采用冰蓄冷系统,并针对负荷逐步增加的实际情况提出分期建设方案,并对集中供冷系统及用户入口的设计进行了介绍。通过分析集中供冷系统的技术经济指标,得出夏热冬冷地区实行区域供冷系统具有一定可行性。
District cooling system has obvious advantages in the energy,operational management and economic aspects,the application of the regional central cooling system in Guangdong Province is introduced,the regional design day load and annual hourly load are analyzed. Available energy is analyzed according to the local conditions,the ice storage system is determined,and the stage construction program is to adapting the gradual increase load of the actual situation,and the design of the central cooling system and ？the heat exchange room for user is introduced. By analyzing the technical and economic indicators of the central cooling system applied in Guangdong Province,the conclusion that the district cooling system applying to the hot summer warm winter zone is drawn.
