Analysis of air distribution and operation mode in a data center with upper supply air conditioning

Because of the huge heat capacity, high heat-density and complex airflow in a data center, selecting a reasonable air conditioning operation mode is very important. By using the eddy viscosity model of computational fluid dynamics, analyses the air distribution characteristics and environmental parameters of upper supply air conditioning system. Through the data analysis of three kinds of air conditioning operation modes, obtains the best operation mode, and provides a practical theory for the design, retrofit and operation of the air conditioning system.
