These absorption chillers from Thermax Inc. take the heat from the turbines and use it produce cold water for the data center’s cooling system. Absorption chillers use a lithium bromide solution to absorb vapor from evaporating water, creating a vacuum. The 585 degree F heat from the turbines re-concentrates the solution and releases the water vapor, which is then condensed in a cooling tower, which returns water to the data center at 45 degrees F (7 degrees C). IBM says this approach increases the amount of cooling generated.
