Why CFD for Energy Efficiency?

While winter temperatures make it a little easier to distract yourself from the costs of data center cooling, the realities are that for many companies, data center cooling remains a topic of high importance. At BRUNS-PAK, we have long championed design options that can make significant difference in your data center HVAC costs, including:

  • Airside Economization: the use of “free” outside air in your cooling plan
  • Heat Wheel Integration: integration of heat wheel exchange systems for optimizing energy efficiency
  • Higher Data Center Ambient Temperature: following the guidelines in ASHRAE 9.9 means real savings
  • Hot Aisle/Cold Aisle Configuration: reducing hot/cold mixing can produce measurable improvements in cooling efficiency

However, one item that companies do not take regular advantage of is CFD Modeling. Computational Flow Dynamics is often used in data center design projects, but its use in understanding airflow and cooling efficiency in existing data centers can yield measurable improvements in the optimized configuration of your data center assets, along with recommendations for HVAC improvements.

As leaders in the use of CFD modeling, BRUNS-PAK can provide expert consultation on ways to leverage this technique to support both short-term energy efficiency optimization modifications, and long-term strategic options for improving your data center sustainability profile.
