The CFD simulation includes steady state analysis & transient analysis of 3D geometry with pressure inlet / mass flow inlet and pressure outlet condition. Analysis is done with Multi Reference Frame (MRF) model with fan rpm as added input to simulate real time behaviour. As the pressure inside the pit is an unknown parameter, the analysis approach followed is to simulate the flow of gases with positive and negative (vacuum) feed pressures and calculate the exit mass flow rate availed. Simulation is also done for rated mass flow rate and the fluid behaviour is cross verified. Transient case is done to check the mass fraction of gas extracted as time progresses.

Data Centre Engineering Consultation

 

  • Establishing an Energy-Efficient Foundation for the Digital Age The digital revolution has been shaping our world for nearly a decade, with the recent pandemic accelerating this transformation. Industries across the globe are going online, embracing the realm of mainframes, and building their digital presence.


  • This ongoing digital evolution demands more robust, well-designed data centre infrastructures that prioritize energy efficiency. Adopting new standards, technologies, systems, and products is crucial for designing such energy-efficient data centres.


  • A key requirement for data centres is an uninterrupted power supply to prevent server downtime for clients. To achieve this, buildings are often over-designed in terms of MEP (Mechanical, Electrical, and Plumbing) systems, resulting in higher costs, bulky frameworks, and additional maintenance.


  • Our team of energy and data centre experts specializes in creating innovative building designs that optimize operational costs without compromising essential requirements.


Our Key Considerations for Data Centre Design Include:


  • Dynamic Ventilation and Cooling Systems: Ensuring ambient temperature is maintained at all times.


  • Comprehensive Performance Evaluation: Assessing data centre performance based on ASHRAE 90.4 standards, rather than focusing solely on Power Utilization Effectiveness (PUE).


  • Adaptive Architecture: Designing flexible and scalable structures that can grow without incurring incremental losses.


  • Holistic Infrastructure Design: Protecting servers from electromagnetic fields and situating them close to power distribution units.


  • Optimized Space and Lighting Solutions: Providing comfortable and accessible aisles for easy maintenance and audits.


  • Cost-Effective MEP Systems: Designing systems with minimal losses and built-in redundancy while keeping costs under control.
