摘　　要：针对现有的机房空调性能评价指标AEER对于新开发机房空调类型考虑的不足,提出一种新的性能评价指标AEER^(*),并给出其推导过程。针对性地选取已完成测试的机房空调的EER数据,分别计算AEER值和AEER^(*)值,得出以下结论:对于压缩机单循环的机房空调,其AEER值和AEER^(*)值较为接近;现行的AEER指标,对于制冷剂泵-压缩机双循环机房空调或其他类型利用自然冷源的机房空调,弱化EER_(a)和EER_(b)这2项评价指标;使用AEER^(*)作为机房空调性能评价指标,更为科学并且贴合实际。A new performance evaluation index AEER^(*)is proposed and its derivation process is given in view of the shortcomings of the existing performance evaluation index AEER of the new developed type air conditioner for computer room.The EER data of the air conditioner for computer room are purposefully selected,AEER and AEER^(*)values of the samples are calculated.It is concluded that for the air conditioner for computer room with single cycle compressor,AEER and AEER^(*)values are relatively close;the current AEER index weakens the two evaluation indexes of EER_(a) and EER_(b) for air conditioners for computer room with refrigerant pumping-compressing dual cycles or other types air conditioners for computer room using natural cold sources;it is more scientific and practical to use AEER^(*)as the performance evaluation index of air conditioner for computer room.
