集中空调系统冷热水泵变频控制节能改造分析

A Focused Analysis of Energy Saving Case of Hot and Chilled Water Pumps Frequency Control in an Air Conditioning System

结合工程案例,通过现场实测,对某大楼集中空调冷热水泵变频控制系统的实际节能效果进行数据分析和理论分析;此外,提出了变频器谐波测试分析结论和变频控制策略,为空调水泵节能提供了分析思路。

Based on a project case and field measurements,analyzing the energy-saving data and results by the use of frequency control of the chilled and hot water pump of the central air-conditioning system in a building.Moreover,we also present the conclusion of the harmonic test of the frequency converter and the strategy of frequency control for providing an analytical thought for the water pump energy-saving of an air-conditioning system.
