    Abstract

    Recently, information and communications technologies (ICT) have been widely used in the air-conditioning field, and high- performance and density ICT facilities have been rapidly growing. At the same time, the heat generated per unit area of a normal data center, where the servers and routers are concentrated, in an ICT facility is an extremely serious problem. Therefore, this study aims to investigate the performance and characteristics of the server spot cooling heat transportation system adopting CO 2 as the working fluid to prevent the occurrence of hot spots and decrease the power consumed by a conventional overall air conditioning system installed at a data center with experiments and simulations. In the result, we determined the optimum CO 2 circulation rate that maximizes the rejected heat flow rate, and minimizes power consumption.
