Résumé

This paper describes the thermal profile of a 23.2 × 29.9 m data center and the measurement techniques employed to fully capture the detailed thermal environment. In a portion of the data center 4.9 × 7.9 m, which encompasses very high powered servers, the heat flux is 5500 W/m2. Most racks within this area dissipated approximately 19 kW. Detailed measurements were taken in this data center of electronic equipment power usage, perforated floor tile airflow, cable cut-out airflow, computer room air-conditioning airflow, and electronic equipment inlet air temperatures. In addition to these measurements, the physical features of the data center were recorded such that a detailed CFD model could be employed to compare the results.
