Abstract
Cooling fluid pressure within a plenum of a cooling system is controlled by activating the cooling system, sensing pressure within the plenum in at least one zone of the data center, determining whether the pressure is within a predetermined pressure range, and modulating at least one of a plurality of automatically adjustable vents in response to the pressure being outside the predetermined pressure range.
Claims29
A method of controlling cooling fluid pressure within a plenum and of cooling a plurality of racks in a data center, said method comprising:
- activating a cooling system having a cooling device in fluid communication with said plenum, said plenum being in fluid communication with a plurality of automatically adjustable vents configured to supply cooling fluid to said racks;
- sensing pressure within said plenum in at least one zone of said data center;
- and
- automatically actuating at least one of said plurality of automatically adjustable vents in response to said pressure within said plenum being outside of a predetermined pressure range, thereby substantially yielding a neutral-to-positive airflow at said plurality of automatically adjustable vents and thus substantially balancing said pressure within said plenum on a zonal basis.
A cooling system for cooling racks in a data center, said system comprising:
- a cooling device for supplying cooling fluid to said racks, said cooling device including a fan;
- a plenum in fluid communication with said fan;
- a plurality of automatically adjustable vents in fluid communication with said plenum;
- and
- means for sensing pressure within said plenum in at least one zone of said data center, said means for sensing pressure producing output upon which said plurality of automatically adjustable vents automatically adjust to substantially balance the pressure within said plenum.
A system for controlling cooling fluid pressure within a plenum of a cooling system for cooling a plurality of racks in a data center, said system comprising:
- means for activating said cooling system, said cooling system including a cooling device in fluid communication with said plenum;
- means for sensing pressure in at least one zone of said data center within said plenum;
- and
- means for actuating at least one of a plurality of automatically adjustable vents in response to said pressure within said plenum being outside of a predetermined pressure range to substantially yield a neutral-to-positive airflow at said plurality of automatically adjustable vents.
