UL SUBJECT 2755-2011模塊化數(shù)據(jù)中心的研究概況

1.1 This Outline of Investigation covers Modular Data Centers (MDC). The Modular Data Centers coveredby these requirements are pre-fabricated units consisting of an outer enclosure housing ITE and varioussupport equipment such as electrical service and distribution equipment, HVAC systems and the like.Some configurations may have the support equipment housed in a separate enclosure. A typicalconstruction may use a standard ISO shipping container or other structure as the outer enclosure, racksor cabinets of ITE, NEC compliant service entrance equipment and power distribution components, powerstorage such as a UPS and an air or liquid cooling system.1.2 These factory-built modules incorporate pre-installed materials and equipment which, afterinstallation, may be concealed and may not be accessible for inspection at the final installation site.1.3 The modular data centers covered by these requirements are intended for fixed installation eitherindoors or outdoors based on their construction and resistance to environmental conditions. MDCsintended for outdoor use shall be identified with a NEMA environmental class rating.1.4 These requirements are intended to demonstrate compliance with the National Electrical Code (NEC),NFPA 70 and other national Codes such as Building, Fire, Plumbing, Mechanical, and the like. Wherestate or local codes differ from the national codes anticipated by these requirements, determiningcompliance with these codes is the responsibility of the local authority having jurisdiction.1.5 When these requirements do not cover a specific technology or construction feature, the applicablerequirements of the National Codes shall be used.1.6 This Outline of Investigation assumes that the final installation of the MDC will be performed byqualified service personnel in accordance with the applicable installation instructions, installation practicesand national installation codes. These MDCs are intended for installation subject to approval by theAuthority Having Jurisdiction.
