摘　　要： 为了提高冷水机组自控水平,便于管理和节能,对一套原来为继电器-接触器控制的冷水机组进行信息化改造。改造方案为:以PLC和触摸屏作为现场控制器和监视器,PLC通过联网模块接入局域网,在局域网客户端上实现对冷水机组的网络监控。为旧中央空调系统的楼宇智能化改造提供比较有价值的参考。 In order to raise the level of automatic control in chiller and manage conveniently and save energy, the informatization construction was conducted for the chiller under relay - contactor control system. The construction scheme was that PLC and touch screen work as local controller and monitor, and PLC was linked to LAN by cybermodule, and the network monitor and control of the chiller were realized by LAN Client. This paper provides some beneficial reference for the BA transform in old centre aircondition system.
