Bi-surfaced raised access floor panel and cold isle forming system in a data center

A containment system for cooling computer servers on a raised floor in a data center, comprising:

• (a) a pedestal support system including a plurality of vertically extending pedestal supports each having an upper end connected to a pedestal support head and a lower end connected to a pedestal support base, said pedestal supports each connected in relation to the other in an on centers each way square matrix orientation with a plurality of horizontal stringers;
• (b) a first row of bi-surfaced raised access floor panels, said bi-surfaced panels each comprising a floor panel sub-frame and a generally square plate member, said plate member having an upper working surface and a lower plenum surface, said lower plenum surface forming a built-up member connection with an upper surface of said sub-frame, said plate having four corner formations and bisected to define a first and a second halves, wherein said first halve is substantially solid load bearing surface, and said second halve is an air grate;
• (c) a second row of air-grate raised access floor panels having a sub-frame and a generally square perforated air grate plate member, said plate member having an upper working surface and a lower plenum surface, said lower plenum surface forming a built-up member connection with an upper surface of said sub-framework, said plate having four corner formations;
• and
• (d) wherein a substantially rectangular cold aisle is formed between rows of the computer servers by locating said first and second rows of floor panels in an orientation so that said second halve of said first row of said bi-surfaced floor panels are aligned adjacent to said second row of said air-grate floor panels, wherein said first and second rows of floor panels are supported on the pedestal support system, so that said perforations, in combination, are capable of circulating an airflow from a lower plenum chamber through a cold aisle formed thereby, and into a front of at least one server cabinet, and whereby at least a portion of said server cabinet is supported on said solid load bearing surface of said first halve of said first row of said bi-surfaced raised access floor panels.
