某数据机房气流组织模拟及运行优化
Air distribution simulation and operation optimization for a data room
摘要：
对某采用风管精确送风的数据机房进行数值模拟，分析机房的温度场和气流组织情况，评估了部分空调机组出现故障或空调温度设定值提高时，机房的温度场分布及对设备运行安全的影响。CFD模拟结果表明，风管送风温度偏低，运行中可能存在结露的风险；如果1台空调压缩机出现故障，在维修恢复前将该台空调整机关停可减轻故障对机柜散热的影响；如果把温度设定值从22 ℃提高到25 ℃，机房整体温度随之升高，机柜进排风温度也会上升2~3 ℃，运行不安全。
Abstract：
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.
