Thermodynamic Tools for Holistic Analysis and Optimization of Energy Efficient Data Centers

Sample Project:

A Chip to Cooling Tower Thermodynamic System Simulator (VTAS)


Ortega, Wemhoff, Fouladi (Villanova University)


Build a data center thermodynamic simulator to model a system constructed from individual components (servers, racks, room, CRAC, chiller, cooling tower, air side economizer)


  • VTAS  (Villanova Thermodynamic Analyzer of Systems) is a MATLAB simulation tool (release 1.0 December 2012)
  • System components are described by both simple and more sophisticated models
  • VTAS allows flow network modeling to compute operating temperatures and pressures; exergy calculations, transient modeling capability for component models
  • VTAS allows modeling of air, hybrid and liquid cooling systems
