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.
Claims45
A data center cooling system comprising:
- a plurality of fans configured to circulate outside air at ambient conditions through an entry zone of a data center;
- a plurality of atomizers positioned upstream of the entry zone 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 fans are further configured to circulate the cooled air from the evaporation zone into the rack zone.
A data center cooling system comprising:
- a plurality of fans configured to draw outside air at ambient conditions into an entry zone of a data center;
- a plurality of atomizers positioned downstream of the entry zone configured to spray atomized water into the 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;
- an air-to-air heat exchanger positioned between the evaporation zone and the rack zone.
A method for cooling a data center comprising:
- drawing outside air at ambient conditions into an entry zone of the data center;
- spraying atomized water into the outside air downstream of the entry zone;
- providing an evaporation zone where the atomized water evaporates and cools the outside air to cool air;
- directing the cool air into a rack zone positioned downstream of the evaporation zone that comprises a plurality of computer racks arranged in a plurality of substantially parallel row, wherein the rack zone is in fluid communication with the evaporation zone.
A method for cooling a data center comprising:
- drawing outside air at ambient conditions into an entry zone of the data center;
- spraying atomized water into the outside air downstream of the entry zone;
- providing an evaporation zone where the atomized water evaporates and cools the outside air to cool air;
- directing the cool air into an air-to-air heat exchanger that is positioned between the evaporation zone and a rack zone;
- directing hot air from a rack zone of the data center into the air-to-air heat exchanger and cooling the hot air to cooled air;
- and
- recirculating the cooled air from the heat exchanger back into the rack zone, where the rack zone comprises a plurality of computer racks arranged in a plurality of substantially parallel rows.
