Air distribution simulation and operation optimization for a data room

Simulates a data room with the duct accurate air supply system, and analyses the temperature field and air distribution. Evaluates the temperature field distribution and the influence on operation security of cabinets when part of the air-conditioners fail or the air conditioning temperature set point increases. The CFD simulation results show that a lower duct supply air temperature may bring about the condensation risk in operation; if one of the compressors fails, the air-conditioner should be shut down before being restored to reduce the influence on cabinet heat dissipation; and if the air conditioning temperature set point is improved from 22 to 25 ℃, the data center temperature will rise and the supply and exhaust air temperature will also increase 2 to 3 ℃ causing the cabinet unsafe operation.
