AirflowSystems are designed for typical hot aisle/cold aisle data center cooling environmentsand installation:l On raised or nonraised floors.l In hot aisle/cold aisle arrangements.The airflow provides less mixing of hot and cold air, which can result in a higher returntemperature to the computer room air conditioner (CRAC). This promotes better heattransfer outside the building and achieves higher energy efficiency and lower PowerUsage Effectiveness (PUE). Additional efficiency can be achieved by sequestering theexhaust air completely and connecting ducts directly to a CRAC unit or to the outside.Best practice is to place a perforated floor tile in front of each bay to allow adequatecooling air supply when installing on a raised floor. The following figure shows typicalairflow in a hot aisle/ cold aisle environment.Figure 1 Typical airflow in a hot/cold aisle environment5654 487 991 1223Table 7 Airflow diagram key# Description # Description1 To refrigeration unit 6 Hot aisle2 Suspended ceiling 7 Perforated rear doors3 Air return 8 Pressurized floor4 System bays 9 Perforated floor tile5 Cold aisleSpecificationsAirflow 27
