Application of air supply control to cold aisle contained data centers

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.
