Conclusion
Under Rack Panels, like the AisleLok® Under Rack Panel, can dramatically reduce the intake air
temperature of IT equipment. The maximum IT inlet temperature reduction in the model was 18.9° F.
The average maximum IT inlet temperature reduction for all the cabinets in the modeling was 10.5° F.
Holistic airflow management, including sealing the gaps under racks, is crucial to achieving the lowest
and most even IT equipment intake air temperature distribution. Achieving low and even IT equipment
intake air temperatures allows for the greatest reduction in operating cost and increase cooling
capacity by adjusting the cooling controls. Modeling of fan speeds showed the ability to reduce fan
speeds by 10% resulting in energy savings of $5,318 annually for the small 2,260 sq. ft. computer room
(@$0.10/kWhr). This equates to $47,059 of annual energy savings for a 20,000 sq. ft. computer room.
Based on MSRP cost for the Under Rack Panel simple payback is achieved in less than 2 months.
