Abstract
The energy required for data centre cooling is a key fraction of total energy consumption in data centres. From a Second Law analysis point of view, the mixing of hot and cold streams in the room airspace caused by hot air recirculation is an irreversible process leading to wasted work potential in data centres. Therefore, a Second Law assessment allows one to quantify the irreversibilities leading to inefficiencies in data centre airspace. In this paper, numerical analyses of flow and temperature fields are conducted in order to evaluate the thermal performance of the data centre. Subsequently, from flow patterns and temperature profiles, First Law and Second Law of thermodynamic analysis of air cooled raised-floor data centres have been performed to reach a better thermal manageability, which will lead to more cost-effective optimum designs. The effectiveness of the exergy-based metric has been studied by analysing the impact of CRAC flow rates. It is shown that using both First Law and Second Law based metrics can be effective tool in evaluating the data centre performance.
