Integrated Control of Multiple Data Centre Cooling Units*

Energy management is one of the biggest challenges in today's fast growing world of technology. While data centres play a critical role as a facility for storage and IT operations, they also consume a significant amount of energy to operate, especially for cooling. Efficient cooling of data centres involves meeting temperature constraints while minimizing power consumption. We first demonstrate the applicability of a zonal model for a modular data centre. We then leverage this zonal model to demonstrate that a joint workload assignment and cooling control problem has a simple solution: equally load the servers and maximize the setpoints of the cooling units to meet redline temperature constraints.
