First, two types of cooling systems for data centers were compared in a real scale experimental room. One was ceiling return system and the other was room return system. For both of them cooling air was supplied from raised floor. As a result, ceiling return system presented better cooling performance as it made room air temperatures lower than room return system. Secondly, we applied these results to practical air conditioning design and created useful equations for designing. Using these equations we found that ceiling return system could make not only running but initial costs for air conditionings less than the other. Finally, computational fluid dynamics (CFD) models were used to evaluate if they could reproduce experimental results and it revealed CFD tools were very useful for designing airflow in data centers.
