Thermodynamic Tools for Holistic Analysis and Optimization of Energy Efficient Data Centers
A Chip to Cooling Tower Thermodynamic System Simulator: The Villanova Thermodynamic Analysis of System (VTAS) tool
Build a data center thermodynamic simulator to model a system constructed from individual components in cooling systems (e.g., servers, racks, room, CRAC, chiller, cooling tower, air side economizer) and electrical distribution systems (e.g., AC transformers, UPS, PDU, converters, rectifiers, inverters)
VTAS (Villanova Thermodynamic Analyzer of Systems) is a MATLAB simulation tool (more information below).
System components are described by both simple and more sophisticated models
VTAS uses 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
Villanova Thermodynamic Analysis of Systems (VTAS)
The Villanova Thermodynamic Analysis of Systems (VTAS) is a chip-to-cooling tower thermodynamic analysis tool for data center cooling systems. It allows for:
- Pinpointing efficiency bottlenecks in data center cooling systems
- Modeling transient system behavior
- Comparing different cooling solutions
VTAS Version 3.14
Version date: 13-Aug-2019
Updates for this version:
- GUI option to lay out individual components
- Validated Level 1 CRAH component model with varying UA
- Option to not specify CRAH outlet humidity
- Various bug fixes, including PUE calculation method
- New accompanying freely-available calculator
- Test suite confidence indicators
