Abstract

Described herein is a data center that provides for efficient cooling using HVAC units positioned outside of the facility.

Claims (38)

1. A facility with an internal area separate from an outdoor environment, the internal area for maintaining electronic equipment disposed in a plurality of cabinet clusters, the facility comprising:

a building that includes an exterior load wall extending in a vertical direction and separating the internal area from the outdoor environment, the internal area containing a volume of air;

one or more wall openings in the exterior load wall;

a floor within the internal area on which the plurality of cabinet clusters are disposed;

a plurality of cabinets for holding the electronic equipment therein, the plurality of cabinets forming a plurality of rows, the plurality of rows forming the cabinet clusters, the cabinets arranged so that the electronic equipment disposed within the cabinets emit heated air from the cabinets;

one or more air conditioning units, located in the outdoor environment that are configured to receive the heated air, condition the heated air to create cooled air, and emit the cooled air back into the internal area;

a warm air escape channel within the building that extends through the one or more wall openings that is configured to direct the heated air from the cabinets, through the one or more wall openings to the one or more air conditioning units;

a cool air pathway within the building extending from the one or more air conditioning units through the one or more wall openings and towards the cabinet clusters to provide the cooled air to a cold aisle; and

the warm air escape channel, the cool air pathway and the one or more wall openings aligned with a top region of the cabinets in the vertical direction.

2. The facility according to claim 1 wherein the one or more wall openings in the exterior load wall are configured to attach to one end of a warm air escape channel connector or a cool air pathway connector.

3. The facility according to claim 2 wherein another end of the warm air escape channel connector or cool air pathway connector is configured to attach to the one or more air conditioning units.

4. The facility according to claim 1 wherein the one or more air conditioning units also receive outdoor air.

5. The facility according to claim 1 wherein the one or more air conditioning units further includes an outdoor air inlet that allows intake of outside air to a filter chamber, and a spring-loaded mechanical closing lever, the spring-loaded mechanical closing lever causing automatic closure of an outside air damper disposed within the outside air inlet upon a disruption in electrical power, thereby preventing intake of the outside air that contains gaseous exhaust to the filter chamber upon the disruption in electrical power.

6. The facility according to claim 1 wherein the heated air emitted from the cabinets is directed toward a central hot air area associated with each cabinet cluster.

7. The facility according to claim 6 further comprising a thermal shield providing a contiguous wall around a hot air containment chamber, that is located above the central hot air area, the thermal shield traps the heated air within the hot air containment chamber and causes substantially all the heated air within the central hot air area to be contained as it rises up from the central hot air area.

8. The facility according to claim 7 wherein the heated air rises up from within the hot air containment chamber into the warm air escape channel.

9. The facility according to claim 7 wherein the warm air escape channel is disposed within the building above the hot air containment chamber, the warm air escape channel being lowerly bounded by a false ceiling.

10. The facility according to claim 1 wherein the one or more air conditioning units are disposed on a ground level support structure.

11. The facility according to claim 1 wherein the one or more air conditioning units recirculate the volume of air at least once every 10 minutes.

12. The facility according to claim 1 wherein the one or more air conditioning units recirculate the volume of air at least once every 5 minutes.

13. The facility according to claim 1 wherein the one or more air conditioning units recirculate the volume of air at least once every minute.

14. A facility with an internal area separate from an outdoor environment, the internal area configured to house electronic equipment disposed in a plurality of cabinet clusters, the facility comprising:

a building that includes an exterior load wall extending in a vertical direction and separating the internal area from the outdoor environment, the internal area containing a volume of air;

one or more wall openings in the exterior load wall;

a floor within the internal area on which the plurality of cabinet clusters are disposed;

a plurality of cabinets for holding the electronic equipment therein, the plurality of cabinets arranged into a plurality of rows of cabinets, the plurality of rows of cabinets forming a cabinet cluster so that the electronic equipment disposed within the cabinets emits heated air from the cabinet;

a thermal shield formed above the plurality of cabinets to direct the heated air into at least one thermal compartment;

one or more air conditioning units located in the outdoor environment that receive the heated air condition the heated air to create cooled air, and then emit the cooled air back into the internal area;

a ceiling;

a false ceiling located beneath the ceiling such that a warm air escape channel is formed between the ceiling and the false ceiling, so that the heated air is lifted upward from the at least one thermal compartment to the warm air escape channel and toward the one or more wall openings and into the one or more air conditioning units;

a cool air pathway within the building, wherein the one or more air conditioning units deliver cooled air through the one or more wall openings into the cool air pathway, and the cool air pathway configured to direct the cooled air towards cold aisles of the plurality of rows of cabinets; and

the warm air escape channel, the cool air pathway and the one or more wall openings aligned with a top region of the cabinets in the vertical direction.

15. The facility according to claim 14 wherein the one or more wall openings in the exterior load wall are configured to attach to one end of a warm air escape channel connector or a cool air pathway connector.

16. The facility according to claim 15 wherein another end of the warm air escape channel connector or cool air pathway connector is configured to attach to the one or more air conditioning units.

17. The facility according to claim 14 wherein the one or more air conditioning units further receive outdoor air.

18. The facility according to claim 14 wherein the one or more air conditioning units recirculate the volume of air at least once every 10 minutes.

19. The facility according to claim 14 wherein the one or more air conditioning units recirculate the volume of air at least once every 5 minutes.

20. The facility according to claim 14 wherein the one or more air conditioning units recirculate the volume of air at least once every minute.
