摘　　要：中央空调耗电量在建筑耗电量中占较大的比重,因此对中央空调节能改造技术的研究具有重要意义。首先介绍了中央空调和水泵的变频调速的基本原理。然后通过对具体实例的分析,提出了一套切实有效的改造方案,针对改造方案进行系统的节能评价。最后得出结论,PLC与变频器应用于中央空调,能够大大降低系统能耗,对我国的节能减排事业具有重要意义。Power consumption of central air-conditioning has a big ratio in building energy, therefore the research of energy-saving retrofitting for central air-conditioning system is significant. Firstly, the principle of central air-conditioning and frequency converted are introduced. A set of practical energy-saving reconstruction system is proposed through analyzing specific case, with evaluation on the energy-saving scheme. In conclusion, the application of PLC and converter in air-conditioning can greatly decrease the energy of the system, which has vital significance to the energy-saving and emission-reduction in China.
