摘　　要：为了实现集中空调水系统的节能控制,分析了集中空调定流量水系统改造为变流量运行的可行性,并结合工程实例给出了利用变频器和工控计算机实现该项目的水系统变流量节能控制方案.硬件系统采用计算机加变频器的电机调速,通过RS-485连接,结构简单、性能可靠;软件部分采用V isualC++6.0编写整个程序,结构清晰、稳定可靠.运行结果表明,采用变频器对中央空调水系统施行变流量改造可以带来良好的节能效果.This paper analyzed the feasibility of convert the constant flow hydraulic system to variable system in order to realize the regulating of the water flow rate in central air conditioning. The detailed design scheme, which uses transducer and industrial computer to implement the hydraulic system energy efficiency controlling for this projiect, is illustrated. The hardware system which uses transducer and computer is connected by RS -485. Software partially uses Visual C ＋ ＋ 6.0 to compile the entire procedure. Result of the project proves the energy-saving effect of this control system.
