数据中心机房上送风空调气流组织及运行模式分析

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

数据中心机房的设备发热量大、热密度高、气流复杂,选取合理的空调运行模式尤为重要。采用计算流体力学的涡黏模型分析了上送风空调的气流组织特性和环境参数,通过对3种空调运行模式下的数据进行分析,得出了该机房空调的最佳运行模式,并为此类机房空调系统的设计、改造和运行提供了切实可行的理论依据。

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.
