摘要
多台冷水机组联合运行系统中,各冷水机组系统大部分时间处于部分负荷运行状态。根据冷水机组COP与其负荷率(PLR)之间关系特性,提出一种自适应的负荷优化分配方法,分别根据具有相同和不同额定制冷量冷水机组的系统,对此方法进行了介绍,并与使用回归方法获取PLR与COP关系的策略进行了比较,发现节能效果更明显。
In the multiple chillers system, the chillers are usually loaded partly in the most of running times. According to the relationship between COP and PLR of the system, an optimal loading strategy is presented. Adaptive method is employed to obtain the relation between PLR and COP, and the objective function of chillers system energy consumption is set up to obtain the optimal PLR through optimizing. The simulation results show that the strategy of using adaptive method to obtain the relationship between PLR and COP and incorporating it into online control in the multiple chillers system is better than regression method for saving energy.
