Optimization Ways and Effect Analysis of Airflow Organization in Data Center Computer Room
摘要
Abstract
The ways to optimize the cooling effect of the airflow organization in the data center computer room include optimizing the overhead height of the floor,combining the variable perforation rates of the perfo-rated floor,and sealing the cold and hot aisles.Compu-tational fluid dynamics(CFD)models were used to ana-lyze and evaluate the optimization effect.There is an optimal overhead height for the floor,which ensures that the maximum temperature at each height section of the computer room is relatively low and relatively evenly distributed,the cold and hot airflow mixing is less,and the air supply efficiency of the air condition-ing system is high.The combination of the variable per-foration rates of the perforated floor can improve the uniformity of airflow organization and distribution,and the optimization effect is significant.When the cold aisle and the hot and cold aisles are closed,the maxi-mum temperature at each height section of the com-puter room decreases,and the cooling effect of the air-flow organization is strengthened.Compared with the closed cold aisle,the closed cold and hot aisles have limited cooling effect on strengthening the airflow orga-nization.关键词
