Abstract:
1. An airflow distribution control system for usage in a raised-floor data center comprising; an under-floor partition with an adaptively controllable flow resistance, the partition being adapted constructed into a plenum beneath the raised-floor in selected positions; a sensor communicatively coupled to the partition that detects a parameter indicative of airflow distribution in the data center, tracks the parameter over time, and adaptively controls the flow resistance beneath the raised floor based on the tracked changes in the parameter to balance air flow distribution to match thermal loads imposed by data center equipment; a plurality of under-floor partitions with controllable flow resistances, the partitions being selectively positioned in the plenum; a network of distributed sensors communicatively coupled to the plurality of under-floor partitions; and a controller coupled to the distributed sensor network and the controllable flow resistances, the controller adapted to determine a spatial distribution of at least one parameter sensed by the sensor network, track the determined spatial distribution over time, and automatically control flow resistances in the plurality of partitions mutually independently based on changes in tracked spatial distribution.
