Abstract
Embodiments of the invention provide high-efficiency cooling in a data center in response to a cooling and/or humidity demand using a system having multiple cooling loops to allow for a higher chilled liquid temperature of a first chilled liquid loop, while maintaining data center room temperature and humidity control. Specifically, the system includes a plurality of integrated cooling systems each comprising one or more specifically sized chillers and a liquid loop to address the cooling demand. A free cooling heat exchanger is coupled to the first liquid loop for use when a wet-bulb temperature surrounding the data center is at or below a free cooling set point of the first chilled liquid loop. The system isolates humidity control components to a second chilled liquid loop, and enables greater control of the first chilled liquid loop of the data center to meet specific IT loads.
