Design Guidance for Command, Control, Communications, and Intelligence (C3I) Facility Cooling Systems

摘要

Design guidance has been developed for cooling systems in command, control, communications, and intelligence (C3l) facilities. This report describes design and equipment alternatives available with special attention to operation, principal applications, cost, advantages, and disadvantages. The alternatives are evaluated and ranked according to their ability to fulfill each of the following criteria: flexibility in meeting load redistribution and load expansion, humidity control, particulate matter filtering ability, static electricity control, backup cooling, reliability, lowest cost for shielding against electromagnetic pulse (EMP) and related phenomena, and lowest life-cycle cost.
