送风控制在冷通道封闭数据中心中的应用
Application of air supply control to cold aisle contained data centers
摘要：
机房空调送风控制方式在调节冷通道温湿度时具有反应直接、迅速的优点。分析了传统的机房空调回风控制模式应用在冷通道封闭的数据中心机房时存在的问题。在实测数据的基础上，分析了回风温度控制和送风温度控制2种方式下冷通道温湿度的稳定性。结果表明：送风控制方式下温湿度的波动明显减小，稳定性好。
Abstract：
The supply air control mode of the data centers air conditioning system features direct and rapid response when adjusting the temperature and humidity of the cold aisle. Analyses the problems existing in the traditional return air control mode of cold aisle contained data centers. Based on the measured data, analyses the stability of the temperature and humidity of the cold aisle through the two methods of return air temperature control and supply air temperature control. The results show that the fluctuation of temperature and humidity at the air supply control mode is significantly reduced, with good stability.
