Abstract
A new type of ducted hot aisle containment system for racks cooling of data center has been proposed and put into practice gradually. However, the related academic research has not been carried out, especially for the improvement of cooling performance and influencing factors for the cooling system. In this paper, one experiment platform with 8 racks in 2 rows with multiple-heat-sources was established and tested under various working scenarios. In terms of improving the cooling performance, airtight treatment on the basis of ducted hot aisle containment system is better than itself and is also better than only collar, which is better than no collar. Besdides, doors closing is better than that doors opening, "V" diffuser is better than "T" diffuser, and “T” diffuser is better than no diffuser. Properly increasing installation ratio of blanking panels and air volume have also favorable impact. The experimental data and results in this paper will be of great significance to the design and application of ducted hot aisle containment system for racks cooling.
