中央空调系统的节能改造

中央空调系统的节能改造有很大的降耗空间，本文论述利用变频器和PLC的逻辑控制功能及数据通讯功能对原有空调系统实施改造的技术方案。对原空调的各个重要系统进行分析后，提出了控制系统方案及实现方法，完成了整套节能系统的改造。运行实践表明，该方案对中央空调系统降低能耗和提高效率具有重要意义。

Energy-saving Renovation of a Central Air-conditioning System

The energy-saving reformation of central air-conditioning system has a great potential space for reducing consumption. This paper expounds the technical scheme to reform the original air-conditioning system by using of the frequency converters and the PLC functions of logic control and data communication, with the analysis of every important systems of original air-conditioning, proposes a scheme of the control system and its implementation method to complete the reformation for the whole energy-saving system. The operation practice shows that the scheme is of a realistic significance for reducing energy consumption and increasing efficiency of the central air-conditloning system.
