Vortex-Enhanced Air-Cool Data Center
  |
Data center suffers the severe hot recirculation (hot exhausted air re-entries the server) historically and it has elevated the cooling expenditure due to a lower cold air set point.
A novel hot aisle design was proposed to address such an issue. A vortex flow forms at hot aisle which prevents the hot recirculation effectively in the new design. It has shown a 3oC server inlet air temperature reduction through the numerical CFD study.
Potential energy saving is possible as it allows a lower fan speed or a higher cold air temperature set point. The results obtained from CFD model are going to be validated through a scale-model as well as the on-site test. |
