1. A data center comprising:
- an access floor system;
IT racks positioned on the access floor system;
an air conditioning unit that produces cooling air;
a first air plenum below the access floor system that receives the cooling air from the air conditioning unit; and
a second air plenum;
the access floor system including directional grate access floor panels located adjacent to at least some of the IT racks, each of the directional grate access floor panels includes one or more vanes that are substantially parallel to the at least some of the IT racks;
the directional grate access floor panels are an outlet of the first air plenum and the one or more vanes are located and configured to direct substantially all the cooling air passing through the directional grate access floor panels at an angle with the vertical directly and evenly on the faces of the adjacent IT racks such that substantially all the cooling air passing through the directional grate access floor panels is utilized to directly cool the adjacent IT racks; and
the second plenum is configured to return the cooling air to the air conditioning unit after the cooling air passes through the IT racks.

10. A cooling system for a data center having an access floor system, at least two IT racks supported by the access floor system, and an air conditioning unit that produces cooling air, the cooling system comprising:
-
directional grate access floor panels in the access floor system, each of the directional grate access floor panels includes one or more vanes that are substantially parallel to the at least two IT racks; an air plenum beneath the access floor system that connects the air conditioning unit to the directional grate access floor panels and is configured such that the cooling air is conveyed from the air conditioning unit to the directional grate access floor panels; and a return air plenum; the directional grate access floor panels are adjacent to the at least two IT racks and the one or more vanes are located and configured to direct substantially all the cooling air passing through the directional grate access floor panels at an angle with the vertical and directly and evenly on the faces of the at least two IT racks such that substantially all of the cooling air passing through the directional grate access floor panels is utilized to directly cool the at least the at least two IT racks; the return air plenum is located and configured to return the cooling air to the air conditioning unit after the cooling air passes through the at least two IT racks. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A method of cooling IT racks in a data center having an air conditioning unit that produces cooling air, the IT racks being positioned on an access floor system, comprising the steps of:
-
providing directional grate access floor panels in the access floor system adjacent to at least some of the IT racks, each of the directional grate access floor panels includes one or more vanes that are substantially parallel to the at least some of the IT racks; conveying the cooling air from the air conditioning unit to the directional grate access floor panels through a first air plenum located under the access floor system; having the one or more vanes direct the cooling air through the directional grate access floor panels at an angle with the vertical such that substantially all the cooling air passing through the directional grate access floor panels (1) is distributed directly and evenly over the faces of the adjacent IT racks and (2) passes directly through the adjacent IT racks; and returning the cooling air to the air conditioning unit via a second air plenum after the cooling air passes through the IT racks. - View Dependent Claims (20, 21, 22, 23, 24, 25)
