Systems and methods for cooling in power distribution centers
A power distribution center includes a housing comprising multiple walls and multiple openings, one or more UPS modules and battery racks, and at least one exhaust air duct disposed above the one or more UPS modules and battery racks. The at least one exhaust air duct has an outlet aligned with at least one first opening. The power distribution center is configured to receive cooling air from outside the power distribution center and convey the cooling air to the one or more UPS modules and battery racks. The one or more UPS modules and battery racks are configured to transfer thermal energy to the cooling air, thereby creating heated exhaust air. The at least one exhaust air duct is configured to receive and convey the heated exhaust air to the at least one first opening to expel the heated exhaust air to an exterior space.
1. A power distribution center comprising:
a housing comprising multiple walls and multiple openings in the walls;
one or more uninterruptible power supply (UPS) modules and one or more battery racks disposed within the housing; and
at least one exhaust air duct disposed above the one or more UPS modules and the one or more battery racks, the at least one exhaust air duct having an outlet aligned with at least one first opening of the multiple openings,
wherein the power distribution center is configured to receive, through at least one second opening of the multiple openings, cooling air from outside the power distribution center and convey the cooling air to the one or more UPS modules and the one or more battery racks,
wherein the one or more UPS modules and the one or more battery racks are configured to transfer thermal energy to the cooling air during operation, thereby creating heated exhaust air, and
wherein the at least one exhaust air duct is configured to receive the heated exhaust air from the one or more UPS modules and one or more battery racks and convey the heated exhaust air to the at least one first opening in order to expel the heated exhaust air to an exterior space.
2. The power distribution center of claim 1 , wherein the at least one exhaust air duct is adjustable in elevation above the one or more UPS modules and the one or more battery racks.
3. The power distribution center of claim 1 , wherein the at least one exhaust air duct is mounted to one or more adjustable sliding rails disposed on at least one of the multiple walls, wherein the one or more adjustable sliding rails are configured to enable an adjustment in elevation of the at least one exhaust air duct.
4. The power distribution center of claim 1 , wherein the cooling air is received from a data center adjacent to the power distribution center.
5. The power distribution center of claim 4 , wherein the cooling air flows from the data center to the power distribution center due to a positive air pressure differential between the data center and the power distribution center.
6. The power distribution center of claim 1 , further comprising:
a flexible air dam disposed between a first exhaust air duct of the at least one exhaust air duct and a first UPS module of the one or more UPS modules, the flexible air dam configured to conform to at least one exterior surface of the first UPS module.
7. The power distribution center of claim 1 , further comprising:
a cooling coil aligned with the at least one second opening, the cooling coil configured to cool the cooling air as the cooling air is received into the power distribution center.
8. The power distribution center of claim 1 , further comprising:
at least one fan disposed adjacent to the at least one first opening, the at least one fan configured to promote movement of the heated exhaust air through the at least one first opening.
9. The power distribution center of claim 1 , wherein the at least one exhaust air duct is insulated.
10. The power distribution center of claim 1 , wherein the at least one first opening is disposed vertically higher in the power distribution center than the one or more UPS modules and the one or more battery racks.
11. A method comprising:
receiving, through at least one second opening of multiple openings disposed in multiple walls of a power distribution center, cooling air from outside the power distribution center and conveying the cooling air to one or more uninterruptible power supply (UPS) modules and one or more battery racks disposed within the power distribution center;
transferring thermal energy to the cooling air from the one or more UPS modules and the one or more battery racks, thereby creating heated exhaust air;
receiving the heated exhaust air from the one or more UPS modules and one or more battery racks by at least one exhaust air duct disposed above the one or more UPS modules and the one or more battery racks; and
conveying the heated exhaust air to an outlet aligned with at least one first opening of the multiple openings in order to expel the heated exhaust air to an exterior space.
12. The method of claim 11 , wherein the at least one exhaust air duct is adjustable in elevation above the one or more UPS modules and the one or more battery racks.
13. The method of claim 11 , wherein the at least one exhaust air duct is mounted to one or more adjustable sliding rails disposed on at least one of the multiple walls, wherein the one or more adjustable sliding rails are configured to enable an adjustment in elevation of the at least one exhaust air duct.
14. The method of claim 11 , wherein the cooling air is received from a data center adjacent to the power distribution center.
15. The method of claim 14 , wherein the cooling air flows from the data center to the power distribution center due to a positive air pressure differential between the data center and the power distribution center.
16. The method of claim 11 , wherein a first exhaust air duct of the at least one exhaust air duct comprises a flexible air dam disposed between the first exhaust air duct and a first UPS module of the one or more UPS modules, the flexible air dam conforming to at least one exterior surface of the first UPS module.
17. The method of claim 11 , further comprising:
cooling, by a cooling coil aligned with the at least one second opening, the cooling air as the cooling air is received into the power distribution center.
18. The method of claim 11 , further comprising:
promoting, by at least one fan disposed adjacent to the at least one first opening, movement of the heated exhaust air through the at least one first opening.
19. The method of claim 11 , wherein the at least one exhaust air duct is insulated.
20. The method of claim 11 , wherein the at least one first opening is disposed vertically higher in the power distribution center than the one or more UPS modules and the one or more battery racks.
