中央空调系统节能降耗改造中PLC与变频器的应用实践探讨

摘要

The power consumption of the central air conditioning accounts for a considerable part of the building energy consumption, the energy saving and consumption reduction of the energy consumption is conducive to the construction of efficient and efficient operation. Described the energy-saving principle and operation of central air-conditioning system, combined with the analysis of a building energy saving renovation examples, gives the scientific and reasonable reconstruction scheme and the scheme were energy-saving evaluation. Experiment results show that, in the central air conditioning system in the application of PLC and frequency converter can effectively reduce low energy consumption of the system and to the construction of energy-saving emission reduction has an important significance.%中央空调的耗电量占了建筑耗电量相当大的一部分，对其进行有效的节能降耗改造有利于建筑高效益地运行。阐述了中央空调系统的运行和节能原理，结合某大厦的节能改造实例分析，给出了科学合理的改造方案，并对该方案进行节能评价，实践结果证明，在中央空调系统中应用PLC与变频器可以有效降低系统能耗，对建筑的节能减排具有重要意义。
