Data Centre Cooling Power

Cooling of the Data Centre is widely recognised as the largest energy loss in the facility and as such represents a significant opportunity to improve efficiency. Improving air flow management is a key element to reducing power consumption from data centre cooling.

The objective of air flow management is to minimise bypass air, which returns to the CRAC units without performing cooling and the resultant recirculation and mixing of cool and hot air increasing equipment intake temperatures. To compensate, CRAC unit air supply temperatures are frequently reduced or air flow volumes increased, which has an energy penalty. Addressing these issues will deliver more uniform equipment inlet temperatures and allow set points to be increased (with the associated energy savings) without the risk of equipment overheating.
