Research output: Chapter in Book/Report/Conference proceedingConference proceeding contribution


The mixing of hot and cold air streams in a data centre room associated with the recirculation of hot air is an irreversible process that reduces the cooling potential and leads to inefficiency. A comprehensive thermodynamic analysis is undertaken to determine strategies to achieve optimum cooling performance. Initially the flow and temperature distributions in the data centre are obtained using a computational fluid dynamics package. Each component of the data centre is then considered as a control volume and a second law analysis is applied to each component to obtain the exergy destruction, and hence the irreversible energy losses, for that control volume. An exergy based performance metric (EPM) is used to quantify the performance of the configuration.
