3D CFD Modeling of UFAD Cooling System in a Sample Data Center

Since 1990, data centers have taken on an increasingly central role in the progress of two parallel areas: Information technology (IT) services and telecommunications. Effective cooling of data centers is important for their proper operation and has a key part since the design of the earliest facilities. As computing capabilities advance, heat dissipations from IT servers have increased from a few kW to more than 20 kW within the past decade, particularly in high-performance server racks. Server rooms need significant advances in cooling technologies to enable the successful deployment of their hardware’s. This approach is about three dimensional CFD modeling of under flow air distribution (UFAD) cooling system in a sample data center with its total instruments. CFD results have been compared with the available experimental data, shown good agreement. Results show, CFD modeling of cooling patterns in a data center can help HVAC designers to decide how much cooling capacity needs to cool data center. Modeling pressures and velocities leads to know if there is recirculation or by-pass air around server racks.
