Study on the Influence of Energy-saving in Data Center by Air Distribution Analysis

With the continuous growth of energy consumption in data center, the requirement for air conditioning system in data center is getting more strict. The design of air distribution is considered as a key factor. Reasonable air distribution scheme could improve cooling effect and reduce energy consumption of air conditioning system. Among the solutions of high heat density in many data centers, the side air supply scheme of fan wall system could improve the non-uniformity of air distribution in the environment of data center. This study will take a typical data center as the research object, a simple and easy-to-implement heat channel closure scheme is introduced. Three cases are designed for different positions of the fan wall system, and the indoor air distribution and temperature distribution of each scheme are simulated by CFD (Computational Fluid Dynamics) analysis. The simulation results showed that the reasonable layout scheme of fan wall system can greatly improve the air distribution in the data center, and improve the thermal environment as well, lead to a better heat removal effect and finally reduce energy consumption of data center.
