简析冷热源群控系统

Analysis of the Group Control System of Cold-heat Sources

结合光启城项目阐述冷热源群控系统,所制定的群控策略不仅满足该项目的空调负荷需求,还能及时响应空调负荷的变化,实现冷(热)源的供冷(热)量与末端用户实际需求量的精确匹配,在满足空调负荷的前提下通过负荷预测控制,优化控制机组运行台数、冷(热)量输出,提高系统的整体运行效率。

The paper discusses the group control system of cold-heat sources for Guangqicheng project. For this project, the group control strategy not only meets the needs of the project＇s air conditioning loads, but also can response timely to changes in air conditioning loads so as to meet the end users＇ actual demand for cold （hot） energy. Under the premise of meeting air conditioning loads, this group control strategy optimizes the number of control units in operation and cold （heat） output by load forecast control to improve the system＇s overall operating efficiency.
