【摘要】 针对多台冷水机组联合运行的一次泵定流量系统,建立其主要设备的能耗模型,以及全局能耗最优化目标函数,运用Matlab软件进行"动态规划"求解,从而实现空调水系统运行策略的优化。最后,结合某实际工程,与仅考虑冷水机组能耗的运行策略优化进行比较,验证了基于全局能耗的运行策略优化节能性更好。 【Abstract】 For the primary pump constant flow rate system with multiple chiller units operate together,the energy consumption model of its main equipments is established with the optimal objective function of integrated energy consumption.The"dynamic programming"is computed with the Matlab software to optimize the air-conditioning water system operation strategy.At last,the optimal operation strategy,which only considering the energy consumption of the chiller plants,is compared with a real project in Zhengzhou province,and the optimal opera-tion strategy based on the integrated energy consumption is verified to achieve better energy efficiency effect. 【关键词】 空调水系统; 全局能耗; 运行策略优化; 动态规划 【Key words】 air-conditioning water system; integrated energy consumption; optimization of operation strategy; dynamic programming
