High Density Cooling Solutions- Taking IT to the Next Level: The Cold Aisle Containment Alternative

摘要

A key strategy to increase cooling efficiency that is currently being deployed in operational data centers and discussed by the IT market at large, is to maximize the separation of cold and hot air flow paths. Aisle containment has emerged as a relatively low cost and easy to implement solution. The testing of the Cold Aisle Containment system validated the assumption that utilizing a cold aisle containment system enables the data center environment to support higher density loads while providing a more efficient use of the environmental equipment. Increased efficiencies of up to 40% were achieved utilizing cold aisle containment in comparison to environments without containment. The CRAC units were able to support ΔT's (supply/return) ranging from 75 to 100℉ (23.89 to 37.78℃), depending on load conditions.
