恒速离心式冷水机组变频改造的节能效果分析

Analysis of Energy Saving Effect of Constant Speed Centrifugal Chiller Frequency Transformation

以无锡某医院一台600冷吨的恒速离心式冷水机组的变频改造为例,分析了其改造前后的性能,并计算了年运行能耗及费用。分析结果表明,对恒速离心式冷水机组进行变频改造的节能效果显著,有推广价值。

Using frequency transformation of 600 tons of constant speed centrifugal chiller unit in a hospital in Wuxi as an example, its performance before and after the transformation of the analysis, annual energy consumption and costs were calculated. The analysis results show that, energy saving effect of frequency transformation of constant speed centrifugal chiller plants significantly, the promotion of the value.
