摘要
在换热节能系统稳态机理模型的建立过程中,使用常规方法难以测量换热参数,这给系统机理模型的确定带来了一定的困难。为了满足系统建模对精度较高和计算量较小的要求,引入了多元逐步回归法对换热参数进行软测量。分别对实际现场采集的数据进行了试验研究,获得了最优回归方程。交叉检验结果表明,该方法是可行的。
In establishment of the steady-state mechanism model for heat exchange energy saving system, some of the heat exchange parameters are difficult to be measured by using conventional method ; this brings certain degree of difficulty for determining mechanism model of the system. Based on the requirements of high accuracy and less amount of computation in system modeling, the method of multiple stepwise regression is introduced to do the soft measurement for heat exchange parameters. The experimental research is conducted with the data collected in the field, and the optimal regression equation is obtained. The cross-validation result shows that this method is flexible.
