Abstract

Information systems play an important role in today's advanced information society. The concentration and performance of the information processing devices that make up these systems are increasingly rapidly, and this has led to an increase in the heat concentration of Data Centers as well. For this reason, air conditioning systems for Data Centers must offer a high level of reliability to constantly maintain appropriate room temperatures. In a previous report, we proposed a calculation method for evaluating the reliability of air conditioning systems - targeting central heat source A/C systems and distributed A/C systems as well as co-generation systems with complex system configurations - and examined the unique features of this calculation method. In this paper, we will use the previously proposed calculation method to conduct the following studies, targeting cases in which the systems have actually been implemented. 1) Study methods for evaluating reliability with consideration to change in the performance of air conditioners, and change in room temperature accompanying A/C system stoppages. 2) In an A/C system comprised of several A/C units, evaluate how the reliability characteristics of each individual air conditioner, and the number of devices that make up the system, affect the overall reliability of the system. 3) Evaluate how the individual units that make up a co-generation system affect the overall reliability of the system.
