摘　　要：分析允差在国家标准GB/T18430.1—2007规定范围内变动对水冷式冷水机组性能测试的影响,研究发现:基于GB/T18430.1—2007的允差范围,会导致对水冷式冷水机组制冷量的不合理判定;同时,基于现有允差范围,还会弱化水侧污垢系数修正温差对IPLV测试工况的影响。研究成果能够为准确测定水冷式冷水机组的性能、冷水机组国家标准和能效标准的修订提供参考,也为设计高精度的试验台提供理论参考。The effect of the allowable deviation changing within permissible range stated in GB/T 18430.1-2007 on the performance test of the water-cooled chillers is analyzed.The study shows that it could lead to unreasonable determination of the cooling capacity of water-cooled chiller and weaken the effect of the corrected temperature difference of water-side fouling factor on test conditions of IPLV according to the allowable deviation of GB/T 18430.1-2007.The research results can provide reference for accurate measurement of the performance of water-cooled chiller and revision of the national standard and energy efficiency standard of chiller,but also provide theoretical basis for the design of high-precision test bench.
