Data Center World 2020: A Virtual Experience

The design relates to a chiller assisted cooling chilled water plant for data centers. In the system and method of the design, a fluid cooler is utilized as the primary means of heat rejection of the chilled water exiting the IT environment in the data center. After passing through the fluid cooler, if the design chilled water supply is above the set point, the water is passed through the water chiller where it is cooled before being pumped back to the IT environment in the data center. The use of a fluid cooler as the primary means of heat rejection of the chilled water allows for a reduction in the size of the chiller plant and emergency power plant sized by 35% which also provides lower initial cost and fuel consumption during emergency operations. Initial reduced construction costs are also attributable to a reduction in pipe and insulation material, and less copper for emergency power distribution. The operational EUE is approximately 1.1.
