二次网供热系统分时分区质-量调节的研究

摘要

对集中供热二次网中存在不同类型建筑的系统进行了运行调节的模拟研究，分析了采用分时分区供暖方案下的负荷变化情况。针对该类型供热系统，提出了采用分时分区质-量调节供热的控制策略，并与典型的质调节方式做了比较，模拟结果显示该控制方案既保证了不同类型建筑热用户的用热需求，又达到了节能目的。%The operation regulation ofsecondary heating system with different buildings types was simulated and analyzed, the changes in load was analyzed under the heating scheme with time-sharing and partitions. For this type of heating system, introduces in detail the time-sharing and partitions mode and constant-variable flow control strategy, compares with the typical adjustment way, shows that the control scheme not only ensures the heat demand of thermal users in different types of building, but also achieves the purpose of energy saving.
