  • Data center with low power usage effectiveness
    Patent number: 8635881
    Abstract: A system for providing cooled air to electronic equipment includes a data center having electronic equipment in operation, a plurality of on-floor cooling units, and a cooling water source. The on-floor cooling units cool air warmed by the electronic equipment. The cooling water source is configured to supply cooling water that reduces a temperature of the on-floor cooling units. The power usage effectiveness (“PUE”) of the system is less than 1.3, wherein the PUE is defined by energy used to operate the data center divided by energy used to run the electronic equipment.

  • CONTROLLING DATA CENTER COOLING
    Publication number: 20130233532
    Abstract: A data center cooling system includes a data center having electronic equipment that is supported in multiple racks; a cooling fluid source; multiple cooling units in the data center, where each cooling unit is configured to cool air warmed by a sub-set of the electronic equipment in the data center; multiple control valves, including a control valve associated with a particular cooling unit of the cooling units; and a controller arranged to modulate the control valve associated with a particular cooling unit, to open or close the control valve to substantially maintain an approach temperature set point of the particular cooling unit.
