Modular Data Center, Rapidly Deployable Solution for Greater Efficiency
Prefabricated modular data centers, often referred to as integrated modular solutions or containerized data centers, are designed to cater to specific business needs, providing a tailored and secure infrastructure that differs from conventional brick-and-mortar designs. Modular data center solutions integrate power, thermal management, and other essential components into a cohesive system that is pre-assembled and factory-tested off-site. This approach greatly minimizes deployment time and the amount of work needed on-site.
Our Client manages a diverse portfolio of innovative IT companies operating in 70 countries across Europe, the Middle East, and Africa. They provide a range of services including managed IT services and consultancy, system integration, cloud and data center solutions, software and hardware offerings, as well as technology distribution.
Scope of Conducting CFD analysis
The modular data center analyzed in this CFD study comprises 10 racks, collectively dissipating 65 kW of heat, and is cooled by five close control air conditioning units (CCUs). The project scope involves creating a 3D CAD model sufficient for performing CFD analysis, generating an appropriate mesh that accurately represents the relevant physical phenomena while ensuring good convergence, executing CFD analysis across various heat density combinations, and producing a comprehensive report that includes conclusions and recommendations for enhancements.
Mesh generated for CFD analysis
The CFD mesh is composed of high-quality polyhedral hex core elements, adhering to the best practices in CFD analysis. The total cell count is 4 million, with refinement applied in areas of high flow and thermal gradients.
CFD analysis results
The primary outcomes obtained from the CFD model include temperature contour plots, velocity streamlines, and heat flux measurements, which provide insights into the thermal behaviour and airflow distribution within the data center. These results help identify temperature variations, assess airflow patterns across the rack rows, and evaluate the effectiveness of heat removal from the IT equipment. The CFD analysis is carried out for four distinct CCU operating combinations, considering the available redundancy in the cooling system to evaluate its performance under different operating scenarios. The selected combinations are intended to represent the most adverse thermal conditions, enabling the assessment of cooling adequacy, temperature control, and the reliability of the proposed cooling arrangement under critical operating conditions.
