Datacentre - thermal and airflow studies
Sizing and optimisation of cooling and ventilation systems for datacentres.
SIL3X supports nuclear stakeholders in the design and sizing of their thermal and fluid systems, as well as providing the necessary justifications for safety studies. We can intervene during the start-up phase by developing tools to compare the performance achieved on site with the expected performance at the nominal operating point. During the operational phase, we provide solutions to optimise the systems.
Design and sizing
Ventilation and airflow
Sizing and verification of ventilation systems: flow rates, pressure losses, temperatures, mixing, dead zones. System approach and local CFD when 0D is not sufficient.
Cooling and chillers
Sizing of circuits and equipment to assess cooling capacities, margins and sensitivity to ambient conditions or design changes.
I&C
Modelling of controls and their interactions with the system physics, to analyse transients before implementation.
Hydraulic networks
Assessment of grace periods, temperature front tracking, pressure losses or balancing.
Atmospheric CFD study
Modelling of hot air recirculation phenomena on cooling towers, heat plumes and their impact on the surrounding environment.
Backup diesel generator
Thermal, mechanical and energy analysis at startup and load recovery, including under constraining ambient conditions.
Performance and operation
Energy optimisation (PUE / WUE)
Assessment of PUE/WUE gains during a change of architecture, regulation or new climatic constraints or cold sources.
Thermo-hydraulic CFD simulation
3D analysis of local phenomena (heterogeneities, mixing, interactions) when the global approach is no longer representative.
Transposition / verification of on-site performance
Verification, validation and qualification of nuclear engineering codes or models, on reference cases, experimental data or independent calculations.
Refrigerant fluid retrofit
Performance evaluation after refrigerant change (regulatory developments): comparison of measurements / expected, and analysis of retrofit or replacement options.
Study simulators
Study simulators adapted to the need: representation of physical systems, integration of models and control-command interfaces.
