乌鲁木齐某数据中心热环境分析及气流组织优化研究
|
摘要
以乌鲁木齐一个实测的典型数据中心为研究对象,利用6SingmaRoom软件对机房的气流组织和热工环境进行模拟.分析机房内不同高度平面的温度分布、空调送回风气流流线分布和气流量分布.针对机房气流混乱、冷热分布不均和局部热点问题提出三个气流组织优化措施,并进行模拟对比分析.结果表明,优化后的机房热环境得到明显改善,空调冷量可以被充分利用,有效避免了局部热点问题.
Taking a typical data center in Urumqi as the research object, the 6 SingmaRoom software was used to simulate the airflow organization and thermal environment of the data center. Temperature distribution of different height planes in the data center, the airflow return airflow streamline distribution and the airflow distribution are analysed. Three airflow organization optimization measures were proposed for the airflow chaos in the data center the uneven distribution of hot and cold and local hot spots. The simulation comparison analysis was carried out. Results show that the optimized thermal environment of the data center is significantly improved, and the air conditioning cooling capacity can be fully utilized, to effectively avoide local hot spots.
