Mixing of hot exhaust with cold supply air causes hot spots

On average, only 40% of available cooling is utilized due to bypass and over-provisioning to eliminate hot spots

Typically, air is supplied well below ASHRAE standards in attempt to control temperature

Despite this gross over-supply (2.5x), 10% of racks still experience hot spots

Getting air where it needs to be when it needs to be there is key

Cooling capacity and rack heat density is not the issue

AdaptivCool™ Room Scale Intelligent Cooling (RSIC) provides thermal and airflow management through a patented network of intelligent active air-movers, sensors, and network hubs, controlled the AdaptivCool™ Cooling Resource Manager.

The RSIC system automatically adjusts airflow based on real-time temperature changes in the data center.

How RSIC Works X X 1 ) Under-floor and overhead airmovers eliminate hotspots and ensure that the right amount of air is delivered at the rack level to keep equipment cool. CRAC set points can now safely be raised. 2) Redundant cooling can now be safely placed in hot standby. Extra cooling is available on demand, but is not consuming energy unless it is needed. 3) Return air temperatures across all CRAC units are evened out, resulting in less CRAC humidity fighting. x

How RSIC Works CRAC Failure ZONE 4 ZONE 1 x Reserve CRAC Unit(s) Automatically Turns On During a severe rise in temperature and/or a CRAC failure, the RSIC system will automatically turn on a redundant unit and rebalance airflow across the room to ensure adequate cooling is maintained at the rack level.

AdaptivCool - Results Summary for MHCP Results for MHCP include: A reduction in the cost to cool the upper room by as much as 46% and the lower room by as much as 52%! A reduced electrical demand of 3,736 MWH Hours per year! At $0.07 per kilowatt hour, that equates to a savings of $261,500 per year! Plus expected $150k from Chiller efficiency A total of 20 CRAC units (8 units in the lower room, and 12 in the upper room) can be placed in “Dynamic Redundancy”, allowing MHCP to have redundant cooling without those units constantly consuming energy! Alternatively, a continuous IT load of 426 KW can be safely added to these rooms!

Results for MHCP include:

A reduction in the cost to cool the upper room by as much as 46% and the lower room by as much as 52%!
