摘　　要：降低数据中心能耗的一个关键问题是降低空调系统的能耗。通过分析流场以及各个机柜负载对温度场的影响,阐明了各机恒负载对全场温升的影响。提出了温升影响矩阵的概念,并以此概念为基础,建立了负载分配优化算法。通过此算法优化分配负载后,全场最高温度能够尽可能降低。经过算例的计算与比较,验证了算法的可行性。Reducing the power consumption of CRAC unit is one of key problems to lower the power consumption of data center. The influence of server thermal loads to tenlperature rise in the whole field inside data center is illustrated by analyzing the flow field and effect of load of each rack on temperature field. The temperature rise matrix and corresponding load distribution optimizing method is suggested. The maximum temperature can be lowered after the method is applied. The method is verified by case study and comparison with other methods.
