高温冷水机组能效特性研究的误区剖析
Misunderstandings over energy efficiency study of high temperature water chillers
摘要：
针对相关文献关于常规冷水机组、高温冷水机组在高出水温度工况下的能效特性评价及对比研究方面的认识误区进行了分析。建议采用热力完善度来比较以上两种机组在同一出水温度工况下的能效特性，认为相关文献所研发的高温离心冷水机组能效特性并不优于现有的常规离心冷水机组。

Abstract：
Analyses some misunderstandings existed in relevant literatures about energy efficiency evaluation and comparison of normal and high temperature water chillers in higher chilled water temperature operating mode. Proposes that thermodynamic perfectness should be used to compare energy efficiency of the two kinds of chillers in the same temperature operating mode. Points out that the energy efficiency of the high temperature centrifugal chiller developed in a relevant literature is not higher than that of normal one.
