A modular pod may include two or more walls, a roof, and a base, an air plenum, an air inlet, and an air economizer. The two or more walls, the roof, and the base may define a substantially enclosed interior space. The return air plenum may be positioned within the interior space. The air inlet may be positioned proximate one of the walls. The air economizer may be positioned within the interior space. The air economizer may include a mixing zone and two or more air shafts. The mixing zone may be in communication with the air inlet. The two or more air shafts may be in communication with the air plenum and in communication with the mixing zone. Each air shaft may taper down from the top end to the bottom end of the air shaft.
1. A modular pod comprising:
a plurality of walls, a roof, and a base defining a substantially enclosed interior space;
a return air plenum positioned within the interior space;
an air inlet positioned proximate one of the walls; and
an air economizer positioned within the interior space, at least one server rack positioned in the interior space downstream of the air economizer, the air economizer comprising:
a mixing zone in communication with the air inlet; and
a plurality of return air shafts in communication with the return air plenum and in communication with the mixing zone, each return air shaft tapering from a first length as measured between the mixing zone and another of the walls at an end of the return air shaft proximate the roof to a second shorter length as measured between the mixing zone and another of the walls at an end of the return air shaft proximate the base.
2. The modular pod of claim 1 , wherein each return air shaft includes at least one wall that includes at least a partially perforated portion that extends from a bottom end portion to a top end portion of the at least one wall, and the at least partially perforated portion at the top end portion of the at least one wall is distal from the return air plenum.
3. The modular pod of claim 1 , wherein each return air shaft includes a substantially constant width, and the first length of each return air shaft proximate the roof is approximately 4 to 8 times greater than the second length of each return air shaft proximate the base.
4. The modular pod of claim 1 , wherein the plurality of return air shafts comprises at least three return air shafts aligned along one of the walls of the modular pod with at least one return air shaft centrally positioned between two sidewall return air shafts, and the at least one centrally positioned return air shaft has approximately double the volume of the two sidewall return air shafts.
5. The modular pod of claim 1 , further comprising an air diverter positioned between the return air plenum and the plurality of return air shafts, and at least one damper positioned between the air inlet and the mixing zone.
6. The modular pod of claim 1 , further comprising at least one of the following positioned within the interior space between the air economizer and the at least one server rack: an air cooling system, an air filter, an uninterrupted power system, or a fan array including at least one fan.
7. The modular pod of claim 1 , wherein the plurality of walls comprise a first end wall, a second end wall, a pair of opposing sidewalls that each extend at least between the first end wall and the second end wall, the first end wall is taller than the second end wall, and the roof slopes downward from the first end wall to the second end wall.
8. The modular pod of claim 7 , wherein the plurality of return air shafts are positioned proximate the second end wall.
9. The modular pod of claim 7 , wherein the first end wall and the second end wall each extend upward from the base at an acute angle relative to vertical.
10. The modular pod of claim 7 , further comprising at least one doorway defined in at least one of the sidewalls at a location closer to the first end wall than the second end wall.
11. The modular pod of claim 7 , further comprising a first doorway defined in one of the sidewalls, and a second doorway defined in the other sidewall, and the first and second doorways located on their respective sidewalls at approximately the same distance from the first end wall.
12. The modular pod of claim 1 , further comprising an architectural skin joined to at least one wall of the plurality of walls.
13. The modular pod of claim 12 , wherein the architectural skin comprises a plurality of horizontal slats.
14. The modular pod of claim 12 , wherein the at least one wall of the plurality of walls includes at least one rail, and the architectural skin is joined to the at least wall of the plurality of walls by the at least one rail.
15. The modular pod of claim 12 , wherein the architectural skin is at least coextensive with the at least one wall of the plurality of walls.
