摘　　要：多台冷水机组联合运行系统中,各冷水机组大部分时间处于部分负荷运行状态.根据冷水机组的性能系数(COP)与其负荷率R之间关系的特性,提出一种新的负荷优化分配方法:将自适应方法用于获取R与COP的关系,进而建立系统能耗方程,利用最优化方法得到最优负荷分配率.结果表明,应用自适应方法获取R与COP的关系,并运用于多台冷水机组联合运行系统的在线运行控制,节能效果优于采用回归方法获取R与COP关系的优化策略.In the multiple chillers system, the chillers are usually loaded partly in the most of running times. According to the relationship between COP and R of the system, an optimal loading strategy is presented. An adaptive method is employed to obtain the relation between R and COP, and the objective function of chillers system energy consumption is set up to obtain the optimal R through optimizing. The simulation results show that the strategy of using adaptive method to obtain the relationship between R and COP and incorporating it into online control in the multiple chillers system is better than the regression method for saving energy.
