Thermal Energy Systems Lab
Backup power units represent a key element in data centres ecosystem; they ensure reliability in case of power outage. These systems are essential, not only for ensuring consistent supply of power but also to maintain cooling for servers. Diesel gensets are commonly used: they are reliable, well established technology but are not green, or silent. Data centres cannot be considered green if they rely on diesel backup solutions; thus we suggest a novel zero-emission alternative. The objective of this project is to investigate and assess the potential of alternative zero emission liquid air systems, which utilize cryogenic fluids, to provide efficient ‘green’ power and cooling back-up. It will also create a test bed for a broad exploration of use of cryogens in data centres; including managing peak ambient temperatures, nitrogen for fire suppressant, super cooling for superfast IT. The main driver and focus of this project will be that of working on system level optimization and component design/testing of an integrated system for data centres cooling. In parallel it is intended to understand the economics of operating the proposed system in a data center environment, to meet power and cooling demands both commercially and sustainably.
