Focus on Fans Delivers Cost Savings on Cooling

Data Center Knowledge (Nov 21 2011) Servers

1. SAN JOSE, Calif. – Data center managers who are under pressure to cut costs may find that pressure is their ally – air pressure, that is. Experts in data center cooling said Friday that minor adjustments to fan speed in air handling units can yield major savings, and in many cases can be more cost-effective than installing containment systems to control airflow. New approaches could make it cheaper and easier for older data centers to improve the efficiency of their cooling systems, according to panelists at Friday’s Data Center Efficiency Summit sponsored by the Silicon Valley Leadership Group. That includes the ability to implement variable frequency drives (VFDs) in cooling systems where they previously have been seen as problematic. Is the ‘Era of Containment’ Over? Containment has been one of the major success stories in the effort to make data centers more energy efficient. By separating cool supply air and warm ... (Read Full Article)
