摘要
本文主要介绍了冷水机组能效标准GB19577—2015中冷水机组的能效限定值和能效等级的变化点。GB19577—2015能效等级依据冷水机组性能系数(COP)和综合部分负荷性能系数(IPLV)两项指标进行划分,并且能效等级从原来的5级变为3级。通过与国际上冷水机组能效标准的比较分析,指出GB19577—2015与国际上发达国家的能效标准存在一定差距。
In this paper,the minimum allowable values of energy efficiency and efficiency grades for water chillers of GB19577—2015 were introduced.The energy efficiency grades for water chillers of GB19577—2015 are divided into three grades according to coefficient of performance（COP）and integrated part load value（IPLV）.After comparison and analysis we discovered that there was still a certain gap between GB19577—2015 and the energy efficiency standards of developed countries.
