Maximum Aisle Length: When equipment cabinets form a continuous row, the aisle length should not exceed 16 meters. Many data center designs have computer rooms where cold air is distributed through a raised floor system tha uses the under floor space as a supply air plenum formed by the raised floor. Cold aisles are ormed by the space. Refer to the latest ASHRAE publication, "Thermal Guidelines for Data Processing Environments", dated 2011. This document can be purchased online at https://www. A dedicated section outlines a detailed procedure for assessing the overall cooling health of the data center and optimizing. This guide provides an overview of best practices for energy-efficient data center design which spans the categories of information technology (IT) systems and their environmental conditions, data center air management, cooling and electrical systems, and heat recovery. (2) The return air outlet is above the back of the A2~A16 and B2~B16 cabinets, and the vertical weak current bridge is placed on the upper part of the B18 cabinet to connect with. 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.
