Data Center Cooling
First Claim
1. A system for providing cooled air to a data center, comprising:
- a data center having electronic equipment, wherein the electronic equipment is in operation;
a cooling water source;
a plurality of on-floor cooling units in the data center, each on-floor cooling unit configured to cool air warmed by a sub-set of the electronic equipment in the data center;
a plurality of proportioning control valves, each proportioning control valve associated with a single on-floor cooling unit; and
a controller, wherein each proportioning control valve is configured to turn in response to a signal from the controller, the valve able to be closed, fully open or partially open, wherein when the valve is closed, water is blocked from the on-floor cooling unit, when the valve is fully open, a maximum volume of water is circulated through the on-floor cooling unit, and when the valve is partially open, some percent less than 100% of the maximum amount of water is circulated through the on-floor cooling unit, and wherein the controller is configured to turn the corresponding control valve in response to a change in temperature.

Abstract
A system for cooling air in a data center includes a data center having electronic equipment in operation, a cooling water source, and a plurality of on-floor cooling units. The cooling water source is configured to retain at maximum capacity a total amount of water. Each on-floor cooling unit is configured to cool air heated by a portion of the electronic equipment in the data center using water from the cooling water source. The total amount of water is insufficient to maintain a leaving air temperature of each on-floor cooling unit below an inside setpoint when a temperature outside of the data center is above a predetermined external temperature.
