Bypass Flow Influence on Energy Performance of Data Center Cooling
Result description
The study aims to describe the influence of bypass on cooling of the data center. In this study, both numerical and experimental methods were combined in order to describe an undesirable effect of the bypass flow; a simplified analytical procedure was also used. The paper first describes basic metrics used when defining main parameters of data center cooling. The following part describes experimental data center where individual experiments were performed. For the needs of CFD simulations, suitable boundary conditions were defined in order to get as close as possible to the real flow inside the data center, based on measurements taken. Finally, a simplified analytical solution was used. On the basis of the analytical solution, detailed information on various components of the simulated data center are applied, the information being obtained during measurement. All three approaches are compared at the end and the influence of missing blanking plugs on the overall energy performance of data center cooling is described with the help of the performed analysis
