Cooling requirements

Use the cooling system requirements table below in conjunction with the cooling requirements graph and chilled airflow area graphic to determine the area of floor tiles to supply chilled air to the system.

The model 9118-575 requires air for cooling. As shown in Figure 1, rows of model 9118-575, and systems must face front-to-front. The use of a raised floor is recommended to provide air through perforated floor panels placed in rows between the fronts of systems (the cold aisles shown in Figure 1).

The following table provides system cooling requirements based on system configuration. The letter designations in the table correspond to the letter designations shown in Cooling requirements graph.
