Abstract
A data center cooling system includes an evaporative cooling system. The evaporative cooling system includes fans configured to circulate outside air at ambient conditions through an entry zone of a data center, and atomizers positioned upstream of the entry zone configured to spray atomized water into the circulating outside air. The atomized water evaporates in an evaporation zone and cools the outside air to produce cooled air, which is directed through racks of computers positioned downstream of the evaporation zone.
Claims29
A data center cooling system comprising:
- a plurality of fans arranged in a plurality of rows and a plurality of columns in a bank of fans, the plurality of fans configured to circulate outside air at ambient conditions through a human-occupiable workspace that includes an entry zone comprising an opening in an exterior wall of a data center;
- a plurality of atomizers positioned downstream of the entry zone and across an area substantially the same as the opening in the exterior of the wall of the data center, the plurality of atomizers configured to spray atomized water into the circulating outside air;
- an evaporation zone where the atomized water evaporates and cools the outside air to produce cooled air;
- a rack zone positioned downstream of the evaporation zone that comprises a plurality of computer racks arranged in a plurality of substantially parallel rows;
- wherein the plurality of fans are further configured to circulate the cooled air from the evaporation zone into the rack zone.
