摘要
介绍了冷源群控节能再调试的意义,引入了冷冻站的能效指标即机房性能系数(COP),提出了以冷机效率为原则的加减机策略,重点分析了冷机在不同工况下的部分负荷效率特性。提出的冷源群控系统节能再调试的基本步骤,对实际工程项目具有现实指导作用。
The re-commission significance of chiller plant automation system was analyzed. The plant coefficient of performance（COP）that is an energy efficiency index,was introduced. The addition and subtraction strategy based on chiller efficiency was proposed. The partial load characteristics of chiller were deeply analyzed in different conditions.The basic steps of energy-saving re-commission of chiller plant automation system were given.
