摘要(Abstract):
水力失调使管网系统的流体机械效率下降,造成能源浪费.而刻画管道的水力状况基础参数是管路阻况系数。由于实际工程的复杂性,设计的管路况系数与实际值有一定的差别,提出了基于多目标优化的方法对空调冷冻水系统的管路进行阻抗辨识,在辨识的基础之上,对水力状况进行评估和调整,在实际工程中有很高的参考价值。
An improperly balanced waterpower system will almost certainly have low efficiency of the water-transport process and use excess energy.And the fundamental parameter that characterizes the hydraulic state of a water pipeline is the hydraulic resistance coefficient(HRC).However,the actual values of the HRC may be different from the theoretical values because of the complexity of actual situation.A novel method-multi-goal optimization(MGO) strategy-for HRC estimation in chilled water system is described.On the base of the identification,the hydraulic state can be evaluated and adjusted,which is very useful to real project.
