摘要(Abstract):

根据冷水机组及水泵性能曲线建立了描述中央空调水系统特性的优化计算模型。使用模拟退火最优化算法,寻找在特定的负荷下,使系统达到最小能量消耗和最优的系统性能时系统中各类参数的取值。同时,分别就该最优化控制方案与标准控制方案进行比较,说明这种优化控制方法的优越性。
The chiller and pump performance curves of the principle is described in detail,and performance curve to established of the optimization model is utilized,It is used that simulated annealing optimization algorithm to find the specific load,in order to access the system under load and the minimum energy consumption superior system performance when the system changes in the state of various parameters to achieve optimal control the overall situation.The optimal control program with the standard control programs is compared,such optimal control program performance is given out.
