摘　　要：工厂建筑冷负荷大,能耗高,提高制冷机房系统能效可大幅降低企业成本,提高经济效益。基于此,本文以广州地区某工厂空调项目为例,通过对设计参数的优化,冷热源系统、输配系统、冷却塔系统的精细化匹配,以及控制策略的选择和运行参数的设定等一系列优化措施,来实现系统整体能效的最大化。根据系统三年运行结果分析,系统全年实际运行能效稳定在5.6以上,能效目标达到了预期的节能效果。Factory buildings often have high cooling loads and energy consumption.Increasing the energy efficiency of refrigeration systems can significantly reduce enterprise costs and improve economic benefits.Based on this,this paper takes a air conditioning project in a factory in Guangzhou as an example.Through the optimization of design parameters,fine matching of cold and heat source systems,distribution systems,and cooling tower systems,as well as the selection of control strategies and setting of operating parameters,a series of optimization measures are implemented to maximize the overall energy efficiency of the system.According to the analysis of the system's three-year operation results,the actual operating efficiency of the system remains stable at 5.6 or above throughout the year,achieving the expected energy saving effect.
