Effect of Data Center Characteristics on Data Processing Equipment Inlet Temperatures

摘要

This paper summarizes computational results for the flow and temperature distribution throughout a data center. Only the above floor(raised floor) flow and temperature distribution were analyzed for a uniform flow velocity exhausting the perforated raised floor tiles. A computational Fluid Dynamic (CFD) model was generated for the room with electronic equipment installed on a raised floor with particular focus on the effects of equipment heat load, perforated tile exhaust flowrate, placement of air conditioning(A/C) units and room height. Fourty racks of DP equipment were arranged in rows in a data center cooled by chilled air exhausting from perforated floor tiles. The chilled air was provided by eight A/C units placed inside a room 12.1 m wide x 13.4 m long. Since the arrangement of the racks in the data center was symmetric only one-half of the data center needed to be modeled. The numerical modeling was performed using a commercial finite control volume computer code called Flotherm(Trademark of Flomerics,Inc.). The flow was modeled using the k-e turbulence model. Results are displayed to provide some guidance on the design and layout of a data center.
