Opengate presents on; Innovations in Data Center Airflow Management at the ASHRAE Winter Conference, Tuesday January 27 2009, Chicago IL.

Chicago IL. ASHRAE Winter Conference: Sustainable Urban Design - Engineering Tomorrow…Today.

With increasing heat loads in the data centers proper management of airflow within rack enclosures has become crucial. While avoiding any mixing of hot air with the incoming cold air, effective management and removal of hot air from the rack enclosures is the key factor in maintaining server inlet air temperatures within ASHRAE recommended guidelines. This seminar provided an overview of issues and covers recent design innovations for airflow management within rack enclosures.

Key points from Opengate’s presentation;

• Managed rack heat containment allows the use of dynamic controls to achieve 1:1 cooling supply to IT demand
• CRAC airflow supply can be delivered based on rack demand rather than under floor pressure
• CRAC units can be turned on or off based on reported airflow consumption of the IT equipment or load
• Cooling efficiency can be maximized by; matching cool air supply to actual demand, raising supply air temperature to upper ASHRAE limits, raising entering water temperature and maximize free cooling hours with economizers
