IT data centres of today consume significant amounts of power which makes thermal management of data centres an extremely challenging task. A detailed thermodynamic analysis of data centres using the first and second laws can be a useful tool in identifying the data centre efficiency. The work presented in this paper describes detailed thermodynamic analysis of an air cooled raised-floor data centre for exploring its optimised performance. Each component of the data centre has been considered as a control volume and thermodynamic laws are applied on each component in order to compute energy losses due to irreversibility. This provides the analytical framework required to design energy-efficient thermal management systems for data centres. Computational fluid dynamics (CFD) is used to build and simulate the flow and thermal fields in the data centre. CFD results have been used to evaluate the exergy destroyed in each of the components (using a purpose-built computer program).
