Why Mathematical Modeling is a Necessity to Manage the Cooling/Energy Efficiency in Todays Mission Critical Facilities
Keywords: data center, energy efficiency, thermal analysis
The presentation will discuss the use of Computational Fluid Dynamics (CFD) techniques in both Design and Operational Management of the modern data center. Efficiency (cost) for any data center is driven by the way that Total Power, Total Cooling and Total Space availability is utilized by the Owner/Operator, at any point in time. To complicate matters, the IT load distribution within a facility changes over time, thus making operational efficiency and best use of total power available moving targets. Further, Owner/Operators have little or no control on the amount of power drawn by a piece of IT equipment. This puts the cooling system at the forefront of any strategy to maximize data center operational efficiency. The presentation will reference a case study that illustrates a simulation-based technique for improving data center energy efficiency. The goal of the case study was to develop a baseline model to understand the current state of power distribution and cooling for the facility. This baseline model was used to extrapolate and make scientifically based engineering decisions aimed at improving operational efficiency as measured in PUE. The case study will be used to illustrate the methodology, highlight common cooling system inefficiencies and compare the ROI of multiple cooling system design options that can reduce cooling system operating costs by up to 25%.
