基于DDC的某中央空调节能改造及应用分析

针对某中央空调系统耗能大,不易管理的情况,提出了对此系统的节能改造方案。采用DDC控制器和变频器,对冷冻水泵及冷却水泵进行节能改造,并增加上位机,实现了对此中央空调的实时监控。

In view of the fact that a certain central airconditioning system consumes a lot of energy and is not easy to manage,this paper puts forward an energy-saving retrofit scheme for this system.Using DDC controller and frequency converter,the cooling water pump and cooling water pump are reformed for energy saving,and the host computer is added to realize the real-time monitoring of the central air conditioning system.
