Following are examples of the recommended locations and shapes of tile cutouts. These examples facilitate two vented floor tiles (61 cm [24 in.] x 61 cm [24 in.] each) in cold aisles, while maintaining an 8-tile pitch.
Aisle Pitch and Tile Cutout Size/Location
Brush seals are strongly recommended for tile cutouts. Tile cutouts need to be cut to the size and shape that will accommodate the brush seals. The following is a recommended tile cutout size without consideration of the brush seal:
any inter-cabinet cables | 12.7 cm (5 in.) wide | 7.6 cm (3 in.) deep |
Unblocked tile cutouts will result in chilled air leakage. This may lead to reduced chilled air supply to hardware equipment through vented tiles, reduced computer room cooling efficiency, increased use of air conditioning equipment, and increased air conditioning operating cost.
