This Research Committee seminar will introduce an open-source, free software package that provides practical, end-to-end (from the IT equipment, to heat rejection, to the ambient) modeling and optimization for data center cooling. The software can be used as a stand-alone tool by data center designers, service consultants and facility managers, or be integrated into existing data center management software for autonomous optimal operation. It is the first practical tool that couples the modeling of airflow-management and cooling systems to enable a global data center cooling optimization. The equation-based Modelica modeling language allows a fast and flexible modeling of various cooling system configurations. Its self-learning regression model enabled by an in situ adaptive tabulation algorithm and a fast fluid dynamics model can predict the critical airflow information under various operational conditions within a few milliseconds. We will demonstrate the usage of our tool at two data centers located in two different climate zones.

Funded by the US Department of Energy, this is the joint efforts of University of Colorado Boulder, Lawrence Berkeley National Laboratory, and Schneider Electric. The software and related publications are available at our project website
