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 conventional data center 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.
