Abstract
An index of air re-circulation in a data center having one or more racks is determined to identify the level of heated air re-circulation into cooling fluid delivered to the one or more racks. The one or more racks comprise inlets and outlets and are positioned along a cool aisle and a hot aisle. The index is calculated by dividing the enthalpy rise due to infiltration of heated air into the cool aisle and the total enthalpy rise of the heated air from the outlets of the one or more racks.
