(Cooling of an IT wiring closet is rarely by design and usually occurs only after a fault or overheating has been generated. Historically, there have been no clear standards for specifying sufficient cooling to achieve predictable behavior within the wiring closet. A suitable IT wiring closet cooling specification should ensure compatibility with the intended load, provide clear guidelines for the design and installation of cooling equipment, prevent oversizing, maximize electrical efficiency, and be flexible enough to accommodate different shapes and types of cooling equipment. Work in the wiring closet. This article describes the theory and practical use of an improved method for developing a wiring closet cooling specification.)
