Server rack cabinet cold aisle installation for computer room or date center. Beyond implementing basic measures such as sealing moisture out of the data center and improving air flow, aisle containment to prevent the mixing of hot and cold air stands out as a method that can dramatically reduce energy costs, minimize hot spots and improve the carbon footprint of data. Cold aisle containment (CAC) is a proven data center cooling strategy that creates physical barriers around cold air supply zones, preventing contamination from hot exhaust air and eliminating the energy-wasting effects of air mixing. 1 Hot aisle/cold aisle layout involves lining up server racks in alternating rows with cold air intakes – the fronts of servers – facing each other (the. To assist in planning for a hot and cold aisle cooling containment system, 3-D graphic files and 3-D computational fluid dynamics models for use with computer aided design software have been made available on Resource Link® at By isolating the cold aisle, containment reduces unintended mixing of cold supply air with hot exhaust air, maintaining uniform, predictable.
