This case study describes the design, installation, and commissioning of a prototype cooling system for an uninterruptible power supply (UPS) system. This close-coupled UPS cooling system provides many benefits over conventional UPS cooling techniques. Some of these are lower first cost (~6%), energy efficiency (230 metric tons annual CO2 avoidance), improved thermal performance, and no UPS room footprint requirements. Additionally, this system provides excellent redundancy and concurrent maintainability.
The prototype close-coupled UPS cooling system was installed in an existing data center as part of the Phase II power expansion project.
